When ordering a Motorized Worm Gear Reducer it is necessary to select a reducer size (series), model, gear ratio,assembly style, and motor description. If accessories are required, they must be ordered separately and in addition tothe reducer.
Orders may be placed by mail, telephone, fax or e-mail.
With the introduction of High Efficiency motors and the rising cost ofenergy machine designers and equipment builders are demandingequipment and components that operate at higher efficiency levels.HUB CITY has designed their own worm gear speed reducersaround a system of gearing that substantially increases theefficiency. This system is called “RECESS ACTION WORMGEARING”. Recess action worm gearing is a venerable and wellproven gear system. The greatest enemy of worm gearing is heat,heat generated by friction resulting from the rubbing action betweenthe worm and worm gear. By reducing friction an entire series ofbenefits are gained, such as a substantial increase in efficiency,
increased wear life, lowerstarting and running torque,and smoother conjugatetooth action.Fig. 1 shows a conventionalgear system with the pitchplane at one-half the workingdepth. Initial contact takesplace at point A (note thedirection of rotation) wherethe follower tooth begins todig into the tip of the drivertooth. As contact progressesfrom point A to point E thereis approach action. Approachaction is a sliding in. It has adetrimental scraping actionwhich tends to wear awaythe surface of the gears. Thefriction is very high (note Fig.3) causing scuffing and thedirection of the friction vectorin approach action opposesthe direction of rotation.From point E to point D thereis recess action. Recessaction is a sliding out with thefollower gear tooth moving
away from the driver. The friction forces in recess action are lowerthan those in approach action, and are in the direction that aidsrotation. In addition recess action tends to cold work the gearsurfaces improving the contact and load capacity.
Fig. 2 shows the same gear set in recess action. Slightmodification of the tooth profile moves the pitch plane from itsnormal center location to the outside diameter of the followermember. The initial point of contact now occurs at point E which ison the line of centers of the gear system. This contact thenprogresses to point D which is completely recess action. The recessaction gear system therefore offers all the advantages that occur inthe recess action portion of a conventional gearing system andavoids the problem conditions that occur in the approach action.
A good example of recess action can be illustrated by a water wheel.If the water spout is behind the vertical center line of the waterwheel, the buckets will be filed before they reach the high point of thewheel. Some energy of the water will be expended in lifting the fullbuckets to the high point of the wheel and therefore there will be apower loss. This is the same as approach action. If, however, the
buckets are filled at the vertical center point of the wheel, then all ofthe energy of the water will be used in the rotation of the wheel andthe amount of power delivered by the wheel will be much greater.
In addition to full recess action gearing, the Hub City gearingsystem also employs the use of larger pressure angles than arenormally found in conventional worm gear sets. The pressure anglesutilized in these gear sets are 20°, 25° and 30°. The use of largerpressure angles enables the gear sets to have a wider face widthand still maintain conjugate action of the tooth forms. Thecombination of larger pressure angles, wider face widths, and theuse of high alloy bronze materials, results in worm gear teeth thatare capable of substantially higher bending loads and surface wearloads.
Fig. 4 shows the contact lines of a conventional worm gear setprojected on the end view of the worm. The contact starts at theoutside diameter of the worm gear and travels up to the outsidediameter of the worm. Fig. 5 shows the contact lines of a recessaction worm gear set projected on the end view of the worm. Herethe contact lines progress across the face of the worm gear. Thetotal length of the contact lines in Fig. 5 is less than that in Fig. 4, butthe position of the contact lines are more favorable relativecurvatural conditions so that the unit loading in regard to surfacestresses can be nearly double those of the lines shown in Fig. 4. Theactual wear load capacity in Fig. 5 is about 150% of that shown inFig. 4. The loading of the worm thread as a cantilever beam issubstantially that of concentrated loads in Fig. 4 while it approachesthat of uniformly applied loads in Fig. 5.
In a worm gear set the lubrication that does the most good iscarried on the face of the worm gear teeth. The lubricant on theworm thread surface tends to be scraped off by the lines ofcontact. The lubricant on a worm gear tooth is pushed ahead of thecontact lines. Through the period of engagement the same thread onthe worm is in continuous contact with the same tooth on the gear.
In Fig. 4 the lubricant on the worm thread is practicallyexhausted by the left part of the contact lines so that the right part ofthe contact lines see virtually none of the lubricant. The lubricant onthe worm gear tooth of the conventional worm gear set is pushedahead of the contact lines toward the outside diameter of the worm.In Fig. 5 the lubricant on the gear tooth and worm thread iscontinually swept ahead of the contact, resulting in more adequatelubrication of both the worm thread and the worm gear tooth.
A continuing test program in the Hub City test facility has proven thatrecess action worm gears are capable of carrying higher gear loadswith less gear wear. The increased efficiency of the gear sets resultsin less energy loss of the Hub City worm gear speed reducers.

Before selecting the proper Hub City speed reducer for yourapplication, a review of the basic engineering principles will behelpful.
TORQUE — The measure of twisting force that produces or tends toproduce rotation. It is measured by multiplying a known factor by itsperpendicular distance from the axis of rotation.
Torque = Load (L) x Radius (R)T = L x R
Torque is generally expressed in terms of inch-pounds or foot-pounds. ALL THE TORQUE VALUES SHOWN IN THISMANUAL ARE IN UNITS OF INCH-POUNDS.
EXAMPLE: A rope supporting a weight of 100 pounds is woundaround a cylinder of 6 inch radius. What is the resulting torque?
T = L x R= 100 lbs. x 6 inches= 600 inch-pounds
HORSEPOWER — The measure of the rate at which work is per-formed. It is equivalent to the amount of work required to lift 33,000pounds one foot in one minute.
Horsepower =Load in pounds x Velocity (FPM)
33,000
HP =L x FPM33,000
RELATIONSHIP OF HORSEPOWER AND TORQUEThe distinguishable feature between torque and horsepower is thattorque is independent of speed or time.
Horsepower is a function of velocity which in turn is a factor of bothradius and speed of rotation (RPM). The relationship between horse-power and torque can therefore be expressed in formula form.
Torque x SpeedHorsepower = 63,025
T (in.-lbs.) x RPMHP = 63,025
RATIO — The relationship between theinput and output speed of the reducer.
Ratio = Input RPMOutput RPM
OVERHUNG LOAD — That force which when applied to a shafttends to produce a bending effect. It is always present when a gear,sprocket or pulley is affixed to the shaft to transmit power.
An application factor must also be applied depending on the methodused to transmit power.
Overhung load (OHL) = Torque x OHL FactorRadius of Gear, Sprocket, etc.
OHL= T (in.-lbs.) x (K)R (in.)
The magnitude of OHL should always be kept to a minimum.Excessive loads could lead to fatigue failure of either the bearing orthe shaft. A good practice to follow is to locate the sprocket as closeto the gear housing as possible. ALL OHL VALUES IN THISMANUAL ARE FIGURED AT THE CENTER OF THE SHAFTEXTENSION. Also, as can be seen by the above formula,increasing the sprocket radius will result in a reduced OHL.
UNDESIRABLE DESIRABLE
EXAMPLE: A sprocket 4 inches in diameter is mounted on a shaft ofa reducer rated at 460 in.-lb. torque. Determine the resultingOverhead Load.
OHL = T x (K)R
460 x (1.00)OHL = 2 = 230 lbs.
ROTATION — Input (High Speed Shaft) to the Hub City “Worm GearReducer” can be either clockwise or counter-clockwise.
OPERATING CHARACTERISTICSVELOCITY LIMITS — Worm gear speed reducers are limited inspeed by the rubbing velocity of the gear set. Gear sets using a steelworm with a cast iron gear are limited to a rubbing velocity 500 feetper minute. Gear sets with a steel, heat treated ground worm andbronze gear are limited to a maximum rubbing velocity of 1,500 feetper minute.
Consult factory for ratings higher than shown in the standardrating tables.
MAXIMUM TORQUE — The minimum speed of 100 RPM DOESNOT illustrate the lowest recommended speed of the worm gearspeed reducers. This minimum speed illustrates the maximumrunning torque of the gear box. The unit will efficiently run at speedsbelow 100 RPM. When it is necessary to knowhorsepower values at these lower speeds simply convert the torqueshown at 100 RPM to horsepower using the actualoperating speed. Maximum momentary or starting torque islimited to 300% of rated capacity for worm gear speed reducers.

Mechanical RatingsThe mechanical capacity of a motorized worm gear reducer is generally based on the surface endurance limit of theworm gear material. In some cases the shear strength of the worm gear material may be the limiting factor such as inlow speed, high torque applications. Maximum mechanical ratings are calculated to be used with a service factor of 1.0.This is for continuous service free from shock loading and a total duration of up to 10 hours per day. Applications out-side of these conditions require further modification of the unit mechanical ratings. The selection tables provided showthe required unit size based on mechanical capacity, for service factors from 1.00 to 2.00. Table 1 defines the servicefactor for various applications.
Thermal RatingsThe thermal capacity of a HUB CITY reducer is the actual horsepower (without service factor) which it will transmitcontinuously for 2 or more hours without the temperature exceeding 200° F.
Thermal ratings may be ignored when the continuous operating period does not exceed 2 hours and the shutdownperiod equals or exceeds the operating period. However, when the operating period exceeds 2 hours or the operatingperiod exceeds the shutdown period, thermal ratings must be considered. If the thermal capacity of the unit isexceeded, a larger unit must be chosen or provision made for additional cooling. Design options listed will provideincreased thermal capacity. The selection tables provided show the required unit size based on thermal capacity.
Worm gear units should have a run-in period of about 50 hours. Abnormal heating may occur during this run-in periodand does not necessarily indicate that the unit is beyond thermal capacity unless heating is excessive or continuousbeyond the run-in period.
Thermal Design OptionsAs a result of continuing research and development programs HUB CITY can now offer several design options which willincrease the thermal capacity of our standard line of worm gear reducers. The addition of these options providesadditional options in selecting and applying worm gear reducers.
The design options available are:
1.THE USE OF HUB CITY SYNTHETIC LUBRICANT. HUB CITY lubricant is available in quart containers and isnormally stocked by our authorized distributors. It is recommended that HUB CITY synthetic lubricant be used in allworm gear applications because of its ability to increase the operating efficiency of the drive. The use of HUB CITYsynthetic lubricant can increase thermal capacity from 10% to 15% depending on unit size.
2.FAN COOLING. Cooling fans are available as a factory assembled option for all units from Series 260 through Series520. Series 260 through Series 520 fans are also available as a field installed option. The use of cooling fans willincrease thermal capacity from 10% to 50% depending on unit size and speed.
The design options may be used in combination and will provide compound effects on the thermal capacity of a drive.The selection tables provided clearly illustrate this.

Table 1 designates the Service Factors for various powersources, durations of operation and shock load classifica-tions. Table 2 defines shock load classifications for variousapplications.
For other operating conditions it is necessary tocompensate for load and power source effects. Theequivalent load torque or horsepower is computed bymultiplying the actual or specified value, by the servicefactor. It is recommended that the unit selected have acapacity equal to or in excess of this equivalent load.
Extreme repetitive shock loads, and those applicationswhere excessively high energy loads must be absorbed(as when stalling), require special consideration toestablish higher service factors. Many applications requirefewer hours of service and the service factors can therefore be reduced substantially (equivalent to anincrease in ratings). Please consult the factory for theseapplications.

When ordering a motorized worm gear reducer, it isnecessary to select reducer size (series), gear ratio,model, and assembly style. The motor description mustalso be specified. If accessories are required, they mustbe ordered separately and in addition to the reducer.
SELECTION EXAMPLE. A belt conveyor, uniformlyloaded, requires a direct coupled worm gear speedreducer to drive a light continuous belt. A 2 HP 1750 RPMelectric motor is to be the prime move. Reducer outputshaft must drive conveyor at approximately 115 RPM. Themachine is expected to operate 24 hours per day.
STEP No. 1. Table 1 (page C-7) indicates service factorrequirement of 1.25 for an electric motor drive underrequired 24 hour uniform load conditions.
STEP No. 2. Decide whether the application will requirethe reducer to be selected based on mechanical rating orthermal rating. Units may be selected based onmechanical rating only if the continuous operating perioddoes not exceed two hours and shutdown period equals orexceeds operating period. Since our example requires 24hours per day service the unit must be selected based onthermal capacity.
STEP No. 3. Refer to the Selection Tables on pages C-9to C-13. Follow the first column down to the 2 HP table.Locate the required Output RPM in the next column. Thenearest value to 115 RPM is 116.7. Follow across to theRatio column, which indicates a 15:1 ratio is required.
STEP No. 4. Note that in many cases, there are severallines for the same ratio. The next column shows theService Factor, and all available series are listed to coverservice factors from 1.00 to 2.00. Since the requirement isfor 1.25 service factor, the first listing, with 1.26 servicefactor, is the correct one. The next column shows theseries 260 would provide this service factor based onmechanical rating only. The next column showing OutputTorque, indicates the resulting torque with 2 HP input, is884 in-lbs.
STEP No. 5. Since this unit also requires a thermalcapacity of 2 HP, the Thermal Selection columns mustalso be used. Follow across to the Basic Unit columnwhich indicates a 320 series is required. The remainingcolumns show the series required with the thermaldevices. The 260 series is listed under the Fan column.
STEP No. 6. The standard 320 series, and the fan-cooled260 series would meet both the mechanical service factorand thermal requirements. Note that the mechanicalservice factor would be 2.75 if the 320 is selected. Eitherone could be used based on customer preference.General specifications are listed on page C-15, showingoverhung load, etc. Dimensions are listed on page C-16 toC-19. Also verify that the required motor HP is listed forthe desired reducer.
STEP No. 7. After the correct series is selected, use thedata below to properly place an order, selecting eitherreducer model or shaft-mounted model as desired.
OUTPUT SHAFT MODELS. Specify Model (324 or 264Fan-Cooled), Ratio (15:1) and Style (A, B or C).
HOLLOW BORE MODELS. Specify Model (325 or 265Fan-Cooled), Ratio (15:1) and Bore Size shown in HollowBore chart.
STEP No. 8. Specify the electric motor description.Available motors are listed on pages C-51 to C-53. Thestandard motor is 1750 RPM 208-230/460 volt, 3 phase,TEFC.

L u b r i c a t i o n a n d I n s t a l l a t i o nHUB CITY WORM GEAR SPEED REDUCER MODELS — These instructionsapply to all HUB CITY Worm Gear Speed Reducer models.
CAUTIONLUBRICATIONALL SPEED REDUCERS ARE SHIPPED DRY, OIL MUST BE ADDEDPRIOR TO OPERATION.
All HUB CITY Worm Gear Speed Reducers are splash lubricated. The uniquedesign of the reducers permits nearly universal mounting by placing a fill,drain and oil level plug at the proper location for mounting positions. Figures1-12 show common mounting positions for the different style reducers.
Review the approved mounting positions and lubrication levels identified inFigures 1 through 12 on this sheet. Do not deviate from the mountingpositions or lubrication levels shown without contacting the factory.
After selecting the position that the unit will be mounted but before operating:Remove Fill and Breather Plug (1, Figures 1-12) and Oil Level Plug (2,Figures 1-12). Clean threads on removed plugs and plug holes withdegreaser. Fill gearbox with recommended lubricant (see next page) to a levelnear the centerline of the uppermost horizontal shaft or until lubricant startscoming out oil level plug hole. Install plugs securely in gear case. Note — Plugwith breather (1, Figures 1-12) must always be installed in the top of gearcase, opposite Drain Plug (3, Figures 1-12). HUB CITY Worm Gear SpeedReducers Series 60, 70 and 80 have drain plug at 3A position.
CAUTIONDo not operate the unit without making sure it contains the correct amount ofoil. Do not overfill or underfill with oil, or injury to personnel, unit, or otherequipment may result.
CHANGING LUBRICANT — After the first 100 hours of operation, drain outinitial oil, flush out the gear case with an approved nonflammable, non-toxicsolvent and refill. Thereafter, oil should be changed at least every 2,500operating hours or every 6 months, which ever comes first.
CAUTIONOil should be changed with greater frequency if unit is used in a severeenvironment such as dusty or humid or high or low temperatures.
WARNINGOil, housings, and other components can reach high temperatures duringoperation, and can cause severe burns. Use extreme care when removinglubrication plugs and vents while servicing the unit.VARIATIONS FROM NORMAL CONDITIONS — Input speeds of more than1,800 RPM may require an adjustment in oil level. Side mount units (seeFigure 1) that run less than 800 RPM with the output shaft vertical may requirea zerk fitting installed to lubricate upper bearing. When input is in a verticalposition consult factory for special lubrication instructions.
Figures 1-4 show four common mounting positions of the shaft output andhollow bore units. Figures 5-8 show four common mounting positions of DropBearing Units. Figures 9-12 show four common mounting positions of verticalmount Units.
When position selected is Output Vertical-Up (Figures 5 & 9) or OutputVertical Down (Figures 6 & 10) an adequate amount of lubrication must besupplied to the upper Bearing through Grease Fitting (4, Figures 5, 6, 9 & 10).
All HUB CITY Drop Bearing Models are equipped with Double Seals on theOutput Shaft. Periodically the Pipe Plugs should be removed (5, Figures 5-8)a Grease Fitting inserted in one plug hole and enough grease injected topurge all of the old grease from between the seals.
CAUTIONIf unit is used in the food or drug industry (including animal food) consult thepetroleum supplier or HUB CITY for recommendations of lubricants whichmeet the specifications of FDA, USDA and/or other authoritative bodieshaving jurisdiction. Standard lubricants are not suitable for these applicationsor these industries.

I n s t a l l a t i o n I n s t r u c t i o n sWARNING
SHIELD ALL R OTATING PARTSFor safety, purchaser or user must provide protective guards over all shaftextensions and any moving apparatus mounted on the unit. The uses isresponsible for checking and complying with all applicable safety codes in his areaand providing suitable shields.
WARNINGWear protective clothing and eye shields when installing or maintaining unit andmachine
WARNINGA unit cannot be used as an integral part of a machine superstructure which wouldimpose additional loads on the unit other than those imposed by the torque beingtransmitted, or by any shaft mounted power transmitting device such as sprockets,pulleys, or couplings.
WARNINGUnits ARE NOT to be considered fail safe or self locking devices. If these featuresare required, a properly sized, independent holding device must be utilized.
WARNINGAny brakes that are used in conjunction with a unit must be sized or positioned insuch a way so as to not subject the unit to loads beyond the capacities publishedin this catalog.
WARNINGMake certain that all tools and other items are clear from rotating parts beforestarting machine. Stand clear, and start machine slowly to be suer all componentsare secure and operating properly.
WARNINGMake certain that the power supply is disconnected before attempting to service orinstall the unit, or remove or install any components. Lock out the power supply,and tag it to prevent unexpected application of power.
OPERATING POSITIONS — Normal Speed Reducer positions are shown inFigures 1-12. For special applications, mounting position may be inclined.However, if position varies more than 15°, it may be necessary to make someadaptations to maintain a sufficient oil level. Contact your local distributor or HUBCITY for recommendations. Input rotation of Speed Reducers can be eitherclockwise or counterclockwise.
WARNINGFor safe operation and to continue the unit warranty, when installing,reinstalling, or replacing a factory installed fastener for servicing purpose, or toaccommodate the mounting of guards, shields or other light load imposing devices,or for mounting the unit, it becomes the responsibility of the purchaser or user toproperly determine the quality, grade of fastener, thread engagement, load carryingcapacity, tightening torque, and the means of torque retention.
COUPLINGS — Flexible couplings to input and output shafts are recommendedbecause they minimize bearing and gear wear caused by slight misalignment.Follow coupling manufacturer’s recommendations for installation and shielding.
SHEAVES AND SPROCKETS — When mounting sheaves or sprockets, thecenter of the load should be located as close to the reducer as possible. Excessiveoverhung loading could result in early failures of bearing or shaft. Refer to thegeneral catalog or contact your local distributor for overhung load ratings. Followmanufacturer’s recommendations for installation and shielding.
CAUTIONThe exterior threaded holes on this drive are for mounting the drive or drive acces-sories (couplings, sprockets, etc.). They are not to be used for lifting the drive orany driver/driven equipment.
CAUTIONInspect shafts and components for paint, burrs, or other imperfections beforeinstalling components. Do not use excessive force or pounding to installcomponents onto unit shafts, as this may cause damage to shafts, bearings, orgears.
SHAFT MOUNT UNITS — The Torque Arm Pad Ref. 4A (Figure 3) can be attachedto any of the four available mounting surface locations of the unit.
Install and position Torque Arm Ref. 4 at 90° to the place (a line drawn) betweenthe center of the output hollow bore and the bolt that attached the Torque Arm 4 tothe Torque Arm Pad 4A of the unit, Ref. (Figure 3). The Torque Arm should bepositioned to be in tension, NOT compression, based on output rotation of the geardrive.
CAUTIONExcessive setscrew torque may cause damage to the output sleeves inhollow bore units. Please refer to the following table for recommendedtightening torque.
Shaft Mount Reducers equipped with QD bushings utilize a bushing on both sidesto provide shaft support. However the keyways on QD bushings are not timed tothe mounting holes, therefore it is not possible to install keys in both bushings. Onekey is sufficient to carry the transmitted torque.
CAUTIONWhen installing Q/D Bushing Kits, follow the Q/D Bushing manufacturerrecommendations for bolt tightening torque and installation methods. Failure to doso could result in damage to the bushings and unit.
CAUTIONTest run unit to verify operation. If the unit being tested is a prototype, that unit mustbe of current production configuration.
RUN-IN PERIOD — A new unit will not operate at maximum efficiency during therun-in period. Increased current draw or heat rise may be seen during this time.
PREVENTATIVE MAINTENANCE — Keep shafts and vent plug clean to preventforeign particles from entering seals or gear case. Inspect periodically for oil leaks.
CAUTIONMounting bolts, coupling fasteners, and other power transmitting devices should beroutinely checked to ensure that all parts of the unit are firmly anchored to provideproper operation (loose fasteners can cause alignment problems and excessivewear). Check end play in shafts. Noticeable movement might indicate service orparts replacement is necessary.
CAUTIONIf the unit cannot be located in a clear and dry area with access to an adequatecooling air supply, then precautions must be taken to avoid ingestion of contami-nants such as water, and to avoid a reduction of cooling ability due to exterior con-taminants.

These general maintenance instructions cover Series 130 through Series 520Worm Gear Reducers. Your reducer may be slightly different than thereducers shown in the figures below, and to the right, but these generalinstructions will still apply.
It is advisable to periodically inspect your Speed Reducer for any signs ofimpending service. Spare or replacement parts can often be ordered andobtained before disassembly is necessary, thus minimizing machinedown-time. The following symptoms can be inspected visually withoutdisassembly and may, in some cases, indicate extensive maintenanceprocedures.OIL LEAKING FR OM SEALS—indicates that shaft and/or seals are worn andneed replacing. Keep dirt and foreign particles off shafts in the area of theseals to minimize wear.OIL LEAKING FR OM INPUT OR OUTPUT CAPS, CAP SCREWS OR PIPEPLUGS—might be corrected by retightening or removal and recoating withLoctite® or pipe sealant as required before tightening. If this does not correctthe leaking condition, disassembly will be necessary to replace o-rings.EXCESSIVE END PLAY OF SHAFTS—if there is noticeable shaft movementwhen couplings are removed and shaft is moved back and forth, it may be anindication of bearing wear. Replacement may be required.EXCESSIVE BACKLASH —would indicate worm gears which might have tobe replaced.HIGH INTERNAL OPERATING TEMPS (ABOVE 200°F OR 95°C)—if a unitexhibits high internal operating temperatures, one or a combination of thefollowing may be the cause.1. Unit is overloaded, application may require replacement with higher
capacity unit.2. Damaged bearings, components or improper bearing setting.3. Improper oil level, lubricant type or lubricant contamination.4. High ambient temperature.5. High speed operation in excess of rated values.
IMPORTANTIn the initial factory assembly, Loctite® is used on the threads of allcapscrews. If any screws are removed, a new application of Loctite® isrequired. NOTE: Screw threads and the threaded hole must be degreasedbefore application of Loctite®.
WARNINGFor safe operation and to continue the unit warranty, when installing,
reinstalling, or replacing a factory installed fastener for servicing purposes, orto accommodate the mounting of guards, shields or other light load imposingdevices, or for mounting the unit, it becomes the responsibility of the customeror user to properly determine the quality, grade of fastener, threadengagement, load carrying capacity, tightening torque, and the means oftorque retention.

M a i n t e n a n c e I n s t r u c t i o n sThe figures on page B-128 represent a general design configuration for HubCity Century Series Worm Gear Speed Reducers. There are design differ-ences from model to model, and a general outline of the basic construction isoffered here for clarification and future reference:
INPUT SHAFT ASSEMBLY STYLES
Motoriz ed Versions
Series 130-380 Single ball bearing construction opposite motor end asshown in Figure 4.
Series 450-520 Double tapered bearing arrangement opposite motorend, not shown
Shaft Input Versions
Series 130-260 Ball bearing construction as shown in Figure 2. No openinput cap.
Series 320-520 Direct mounted tapered bearings, straddle mounted onworm, and open input cap used as shown in Figure 3.
Housing Construction
Series 130-260 Have 56C/143TC flange cast integral with housing. Allother input flanges and all other models utilize bolt-onconnection.
Series 130 Utilizes an expansion plug instead of high speed cover(Ref. #4)
OUTPUT SHAFT ASSEMBLY STYLESAll series, with the exception of the Series 130, use a straddle mountedtapered bearing design as shown in Figure 1 on both shaft and hollow boreoutputs. Series 130 uses ball bearings.
Series 450, and 520 hollow shaft units have flanged output sleeves.
DISASSEMBLY PROCEDURE
CAUTIONThe exterior threaded holes on this drive are for mounting the drive or driveaccessories (couplings, sprockets, etc.). They are not to be used for lifting thedrive or any driver/driven equipment.
WARNINGMake certain that the power supply is disconnected before attempting toservice or install the unit, or remove any components. Lock out the powersupply, and tag it to prevent unexpected application of power.
Refer to the figures on page B-128 for the discussion on assembly anddisassembly procedures.
1. Disconnect reducer from drive motor, couplings, or driven shafts to guardagainst personal injury. Remove all sprockets or sheaves from reducershafts with a puller tool to prevent accidental damage to shafts.
2. Remove Pipe Plug from bottom of Gear Case and drain all lubricant fromunit.
WARNINGOil, housings, and other components can reach high temperatures duringoperation, and can cause severe burns. Use extreme care when removinglubrication plugs and vents while servicing the unit.
WARNINGWear protective clothing and eye shields when installing or maintaining unitand machine.
3. If old seals are to be salvaged, cover keyways with cellophane tape,plastic shim stock, or paper before sliding seals over keyway. Remove capscrews from Output Shaft Caps (2) and CAREFULLY remove output shaftassembly. Be careful to keep bearings clean andnot to damage Worm Gear (8) teeth.
4. Remove cap screws from closed input cap (4)and open input cap if applicable. Series 130requires removal of expansion plug. The expan-sion plug is a non salvageable part. CAREFULLY remove input shaft assembly. Onmotorized units, remove entire quill assemblyfrom the back of the unit. On shaft input units,remove input seal (18) or open cap if applicableand snap ring (27) if used and press worm shaftout through front bearing (9). NOTE: Someseries allow removal of input shaft assemblywithout removal of front seal through closed capend. On Series 80, remove bearing locknut, lockwasher, and flat washer. Press input shaft out ofhousing and bearings.
5. Examine Seals (13) for wear or damage and remove from caps or housingonly if replacement is necessary. (When servicing units, seals shouldalways be replaced.) When removed from caps or housing, seals shouldnot be reused.
6. Remove Bearing Cups (11) from output caps and input caps whenapplicable with a puller tool. If driven out, gently tap opposite sides of thebearing cups with a flat punch so they are removed evenly and no damageoccurs to caps.
7. To remove Worm Gear (8) and Bearing Cone (12) from Output Shaft (6),rest one side of gear on blocks and press shaft through gear and onebearing cone as shown in Figure 5.
CAUTIONDo not attempt to strip the gear and both bearing cones off the output shaft inone operation. The Key (17) will lodge against Bearing Cone (12) and severedamage will occur.
Series 450, and 520 units have flanged output sleeves on the shaft mountmodels. To remove the worm gear from these models, the sleeve must bepressed out so gear moves away from the flange. The back side of the flangeis recessed to allow a puller to be used to remove the bearing cone from theshort end of the output sleeve.
8. If input shaft bearings are to be reused, use bearing puller tool or properbearing removal fixture so no damage occurs to bearings.
ASSEMBLY PROCEDURE
1. All parts, including the gear case, should be cleaned thoroughly with anapproved, non-flammable, nontoxic solvent. Any accumulation of sludgedeposits or corrosion should be removed. Whenever input or output capsare removed, it is recommended that seals and shims be replaced. Theseand other miscellaneous items are included in each Reducer Repair Kit.Before reassembly, examine input and output shafts for grooving in theshaft seal area. If the shafts are to be reused, polish out any imperfectionswith a fine grade of emery cloth. The polishing motion should becircumferential, not axial or spiral in direction. Shaft grooving .010 deep orgreater cannot be corrected by polishing. These shafts should be replacedor the seal installed in a new axial location to allow contact in non groovedareas. Some units do not allow space for repositioning of the seal.

2. Replace Bearing Cups (14) in output caps and input caps when applicablebeing careful to remove any foreign particles in the counterbore. Bearingcup must seat squarely in counterbore of cap. If cups must be tapped intoplace, use a rubber hammer or brass driver to protect cup surfaces. Do notinsert seals at this time.
3. PREASSEMBLY OF INPUT AND OUTPUT SHAFTS.IMPORTANT: The Models 130-380 motorized style input and Series 130-260 shaft style units use a National Fine Grade 8 cap screw to secure therear ball bearing to the shaft. The assembly procedure for the cap screw iscritical and MUST be followed to assure proper gearbox operation.A. Clean the cap screw to be free of dirt and oil.B. Clean the threaded hole with a swab or air pressure.C. Apply Loctite® Primer N to the threaded hole. Do this before
preassembly so the primer is dry when you are ready to install the screw.D. Assemble the rear bearing, taking care to press on bearing inner race
only.E. Slide the flat washer onto the screw.F. Apply green Loctite® #640 to the screw and also the threaded hole in
the worm.G. Tighten the screw to the appropriate torque as listed below.
Series Cap Scre w Tightening Torque130 5/16-24 x 3/4 20 ft.-lbs.180 5/16-24 x 3/4 20 ft.-lbs.210 5/16-24 x 3/4 20 ft.-lbs.260 3/8-24 x 1-1/4 37 ft.-lbs.320 1/2-20 x 1-1/2 90 ft.-lbs.380 1/2-20 x 1-1/2 90 ft.-lbs.
NOTE: PREASSEMBLY OF BALL BEARING STYLE INPUT SHAFTS.Series 130 and 210 require assembly of the rear ball bearing in the housingafter the worm shaft has been inserted. Models 180 and 260 can have bothbearings preassembled before final assembly. The procedure for securing thecap screw listed above should be carefully followed for Models 180 and 260at this time.
When reassembling worm and worm gear assemblies, refer to Figures 1 and2 so that all parts are included in their proper position. Be sure that parts arepressed tightly against one another and that noforeign material is included between them. If shafthas a shoulder, the appropriate gear, spacer, orbearing must be assembled tightly against it.
Figure 6 shows the recommended method ofpressing the Bearing Cone (1) onto the Shaft (3).An Inserting Tool (2) is shown pressing evenly onthe bearing inner race. This tool may be machinedfor this purpose in your shop. A substitute insertingtool may also be made from tubing which wouldhave an I.D. sufficient to accept the shaft and anO.D. no lar ger than the inner bearing race.
CAUTIONContact on the cage of the bearing, or using thebearing cup to press the bearing on, will damagebearing.
4. Installation of Input AssemblyA. Shaft input styles using ball bearings, Models 130-260.
Install preassembly into housing. Models 130 and 210 will require installationof rear bearing while input shaft is in the housing. Install washer and capscrew, taking care to follow the procedure outlined in Section 3 on these models at this time. Then install proper amount of shims (24) between bearing outer race and end cap to eliminate any axial movement of bearingouter race. Liberally add grease to o-ring (25), Loctite® cap screws (14) andtighten properly.
B. Shaft input styles using tapered bearing. Models 320-520.Install preassembly into housing. Preassembly will consist of worm shaft andtwo bearing cones. Install two (2) each shims 23 & 24 between gear case andinput caps. Bearings are adjusted by adding or removing shim until bearings
bind, then adding one .002 shim at a time until shaft rotates freely with .001-.003 endplay. Liberally add grease to o-ring, Loctite® cap screws and tightenproperly.On Series 80, install only Roller Bearing Inner Race on input shaft. Install shaftin housing, install Inner Bearing Cup, then press both bearing cones onto shaft.Install Outer Bearing Cup, flat washer, lock washer, and locknut. Tighten lock-nut fully and bend tang of lock washer into slot on locknut. Install roller bearinginto housing and install open cap. No bearing adjustment is required at opencap. Adjust tapered roller bearings with gaskets at closed cap.
C. Motorized style assemblies using a single ball bearing. Models 130-380.Install preassembly in housing. All units should have bearing installed on shaftand cap screw assembled by following procedure listed earlier at this time.Install proper amount of shims (24) between bearing outer race and end capto eliminate any movement of bearing outer race. Liberally add grease to o-ring (25), Loctite® cap screws (14) and tighten properly.
5. Installation of the output assembly. IMPORTANT: The Worm must becentered on the Worm Gear for maximum gear life. Follow the procedure belowto achieve proper bearing adjustment and gear position.A. Insert output assembly carefully into gear case so that worm is meshed with worm
gear. Install one each .002 and .005 shims (22) (23) on each Output Cap (2,Figures 1 and 2) and install caps over shaft. Fasten caps and shims to gear caseby torquing down cap screws evenly.
B. Adjust bearings by removing or adding shims untilbearings bind. Then add one shim at a time until shaft rotatesfreely, with no endplay. NOTE: the position of the gear will becloser to center if the total shim pack thickness on each capdoes not vary by more than .005. After adjusting bearings,but before permanently bolting output caps or installingo-rings, coat worm gear teeth with blueing compound.
C. Turn Worm Shaft (7) by hand while putting a slight load onoutput shaft so that worm marks contact points in blueingon gear.
D. Sight through pipe plug holes with an inspection light and determine if the contactof the worm is centered on both sides of the gear. If worm is not centered, thegear position must be shifted by moving shims from one side to the other. Thiswill maintain proper bearing adjustment. See Figure 7.
E. Liberally apply grease to o-ring and Loctite® cap screws and tighten properly.
6. Oil Seals (13, Figures 1 and 2) can now be installed in input and output caps.Before installing seal, coat O.D. of seal with Permatex and apply grease to seallips. Force should be applied evenly, with a driver, near the outer edge of the sealuntil seals are flush with outer surface of caps. If seals must be installed withouta seal driver, a rubber hammer or brass driver should be used to protect the seal.
CAUTIONDamage to seals can be avoided by covering the shaft keyways with cellophanetape, plastic shim stock, or paper before sliding seals onto the shaft. The springloaded lip of the seal must face toward the inside of reducer to operate properly.
7. Apply sealant to drain plug and replace in the bottom of the gear case. Removefill and breather plugs and fill gear case with recommended lubricant, followingall the procedures detailed in the Lubrication and Installation Instructions whichare included with Speed Reducer.
CAUTIONDo not operate the unit without making sure it contains the correct amount of oil.Do not overfill or underfill with oil, or injury to personnel, unit, or other equipmentmay result.
CAUTIONDo not mix nonsynthetic and synthetic oil in the unit.
WARNINGMake certain that all tools and other items are clear from rotating parts beforestarting machine. Stand clear, and start machine slowly to be sure allcomponents are secure, and operating properly.For further information that may be helpful, see the Lubrication, Installationand Illustrated Replacement Parts sheets for your Speed Reducer.
