RPP BELT PROFILE

RPP PANTHER ULTRA-CORD belts have the proven reinforced parabolic profile. The RPP beltprofile is illustrated in Figure 1. The RPP belt profile, a deeper and more efficient belt toothdesign, enables the belt to transmit more power, while occupying less space.

The reinforced parabolic profile of the RPP PANTHER ULTRA-CORD belt has an angle whichincreases from the base to the top of the tooth. This increasing angle enables a deeper toothdesign.

The reinforced parabolic profile in conjunction with the increased tooth depth results in the following advantages:

• A substantial reduction in noise compared to standard profile and similar curvilineartooth designs, and an even greater reduction when compared to chain and other mechanical drive systems.

• An improvement in tooth jump resistance.

• An increase of torque and power transmission capability.

• Higher resistance to tooth shear.

• Improved belt and sprocket meshing.

RPP PANTHER ULTRA-CORD Belt Features

RPP PANTHER ULTRA -CORD belts are particularly recommended for efficient, compact drives whichexperience high torque loading.

RPP PANTHER BELT FEATURES

• Wide range of sizes in 8mm and 14mm pitches. (See Table 1 - Page 9)

• Highest horsepower ratings of any rubber synchronous belt in the industry.

• More compact drives.

• Reduced noise. (See Figure 2 - below)

• No lubrication or maintenance as required for chain drives.

• Allows the use of idlers on the backside of the belt unlike competing polyurethane systems.

• Precision ground backside for reduced vibration.

Figure 2

Because the RPP PANTHER ULTRA-CORD retains the already proven RPP belt profile (recognized as the quietest system on the market), it possesses all the known advantages of low noise of the RPP belt profile. Inaddition to this it has the extra advantages of:

• Further reduction of noise by reduced belt widths due to the higher performance rating of the system.

• Low noise characteristics compared to drive systems using polyurethane, steel etc. due to the rubber construction.

• Use of smaller diameter sprockets create lower belt speeds and thereby less noise.

RPP PANTHER ULTRA-CORD Belt Features

The new RPP PANTHER ULTRA-CORD Belt achieves a level of performance previously possible only withmechanical drive systems (chain, gears, line shafts etc.) which contain inherent disadvantages of weight, noise,cost and maintenance. RPP PANTHER ULTRA-CORD Belt enters the market with physical characteristics that yieldoutstanding versatility unavailable in other belt drives or mechanical systems.

The RPP PANTHER Drive System (belt and sprockets) can supply up to 125% more horsepower than RPP PlusBelts, providing the most complete product line in the industry. This data is presented graphically in Figure 3 above.

Because of the positive engagement and high flexibility of RPP PANTHER ULTRA-CORD Belts, high levels of effi-ciency are obtained. A well designed and installed RPP PANTHER system will be 98% efficient and will retain thisefficiency with minimal maintenance. Chain and V-belt drives possess inherent inefficiencies and require a highlevel of maintenance (lubrication and retensioning). Many of these systems are currently in use with efficiencieswell below 95%. This significant increase in efficiency can result in a payback of the initial cost differential within avery short period of time.

CLASSIFICATION OF RPP PANTHER ULTRA-CORD BELTS

RPP PANTHER ULTRA-CORD belts are available in 8mm and 14mm pitches.The dimensional parameters for these RPP PANTHER belt pitches are shown in Figure 5.

Figure 5

To obtain a full description of the RPP PANTHER belt the following data is used:

a) Belt Pitch: The distance in millimeters between two adjacent tooth centers as measured along the pitch line of the belt. (See Figure 6)

b) Belt Pitch Length: The total length (circumference) of the belt as measured along the pitch line. (The theoretical pitch line of an RPP PANTHER belt lies at the center of the tensile member.)

c) Belt Width: The width of the belt measured in millimeters.

Figure 6

Tolerances on belt width are shown in Table 4 on page 10.Tolerances on belt thickness are shown in Table 5 on page 10.All RPP PANTHER belts are supplied with ground back to class 2 thickness tolerances.Belts with special controlled thicknesses (ground to class 1 tolerances) are offered forapplications where variations in belt thickness cause problems such as vibration, conveying problems etc...

RPP PANTHER ULTRA-CORD BELT SPROCKETS

RPP PANTHER ULTRA-CORD SPROCKETS

The RPP sprocket tooth profile has been designed and perfected to be used in conjunction with the RPPPANTHER ULTRA-CORD belt profile. This sprocket profile is mandatory in attaining maximum func-tionality of the drive.

NOTE: RPP PANTHER ULTRA-CORD SYNCHRONOUS BELTS SHOULD ONLY BE USEDWITH RPP PANTHER SPROCKETS.

These sprockets are specifically designed to handle the high loading imposed by the RPP PANTHERULTRA-CORD belts. Extensive testing and market feedback confirms the reliable nature of the RPPPANTHER ULTRA-CORD system.

RPP PANTHER ULTRA-CORD Sprockets are easily identified by their black finish.

Carlisle RPP PANTHER ULTRA-CORD sprockets are constructed from high quality materials, and manufactured under high standards of quality control with particular attention to the tight dimensionaltolerances required. The sprocket teeth are designed to mesh and conform exactly to those of thebelt, resulting in a drive which functions as a precision gear system.

RPP PANTHER ULTRA-CORD SPROCKET NOMENCLATURE

A typical sprocket designation is detailed below:

QD Bushings Bore & Keyset Dimensions

Standard keyseats are used in the bore of all bushings. However, as the bore increases in size, it may be necessaryto reduce the depth of the keyseat. When this happens, the correct rectangular key to suit is furnished at no charge.This does not affect the ability of the bushing to carry the load. The rectangular key, or flat key as some call it, fits inthe standard keyway in the shaft.

The Metric system does not refer to keyseat or keyway dimensions as does the English system. Instead, dimensions aregiven for the key itself, which is rectangular in shape, not square as in the English system. This meets ISO standards.

This nomograph shows the maximum speed limit (in rpm) for a standard statically balancedsprocket of a given diameter and face width. To exceed this speed limit the sprocket should alsobe dynamically balanced.

To use, lay a staightedge between diameter and face width. Read maximum rpm recommendedfor standard balance where edge crosses slanted line. For faster speeds, dynamic balancing isrecommended.

EXAMPLE: If a 20 in. diameter x 5 in. (127 mm) face width sprocket runs faster than 1575 rpm,dynamic balancing is recommended.

NOTE: CAST IRON PRODUCTS CAN SAFELY OPERATE UP TO A MAXIMUM SPEED OF 6500 FEETPER MINUTE. SPROCKETS REQUIRED FOR FASTER SPEEDS MUST USE DUCTILE IRON WHICHHAS A MAXIMUM SAFE OPERATING SPEED OF 10,000 FEET PER MINUTE.

RPP PANTHER ULTRA-CORD Drive Selection Procedure

SAFETY NOTE � WARNING!FAILURE TO FOLLOW RECOMMENDED APPLICATION INFORMATION AND RECOMMENDED PROCEDURESFOR INSTALLATION, CARE, MAINTENANCE AND STORAGE OF PRODUCTS MAY RESULT IN FAILURE TO PER-FORM PROPERLY AND MAY RESULT IN DAMAGE TO PROPERTY AND SERIOUS BODILY INJURY. MAKE SURETHAT PRODUCT SELECTED FOR ANY APPLICATION IS RECOMMENDED FOR THAT SERVICE.

RPP PANTHER BELT DRIVE SELECTION PROCEDURE

The selection of a stock RPP PANTHER belt drive is accomplished by completion of the following:A. Collection of basic drive data.B. Calculation of system design horsepower.C. Selection of belt pitch.D. Determination of belt length, sprocket diameters and center distance.E. Determination of required belt width.F. Determination of sprocket requirements.G. List selected material components.

A) Collection of Basic Drive Data: (use drive assistance data sheet, See Table of Contents)1A) DriveR: Type, power rating, rpm and shaft diameter.2A) DriveN: Type, power absorbed, rpm and shaft diameter. Does shock loading exist?3A) Service: Intermittent, periodic, or continuous.4A) Layout: Maximum sprocket widths and diameters, center distance, drive orientation and idler details.5A) Drive Orientation: Vertical or horizontal shafts.

6A) Drive Design Considerations:a) In most cases, the RPP PANTHER ULTRA-CORD belt will be considered in drive situations where its

significant increase in horsepower capacity allows the belt to be used in place of an extremely wide belt of lesser capacity or in situations where a chain would normally be utilized. For this reason, it is mandatory that RPP PANTHER ULTRA-CORD sprockets be used in conjunction with the belt to assure that the completedrive system consists of components of equal capacity. These sprockets are specifically designed dimensionally to enable proper meshing of the belt and sprocket and structurally to withstand the high load capacity of the belt.

b) In situations where speed-diameter combinations result in sprocket rim speeds above 6500 feet per minute,cast iron sprockets are not sufficient and special ductile iron sprockets must be used.

c) On all two-sprocket drives, the minimum flanging requirements are two flanges on one sprocket (normally thesmaller sprocket), or one flange on each sprocket on opposite sides. On vertical shaft applications, one sprocketshould be flanged on both sides and all other sprockets in the system flanged on the bottom if the sprocket axes parallelism cannot be held within 0.001 inches per inch of sprocket face width. On drives with more thantwo sprockets (including idlers), the minimum flanging requirements are two flanges on every other sprocket orone flange on each sprocket, alternating sides around the system.

d) Idlers can be used to clear obstructions, increase wrap, or to provide for installation and tensioning allowances on fixed center drives. They should be located in the slack belt span and can be on either the inside or backside of the belt. Inside idlers should be no smaller than the smallest load sprocket in thesystem. Inside idlers shall have the RPP PANTHER ULTRA-CORD Belt tooth profile unless they are larger in diameter than a 40 tooth sprocket. Flat inside idlers and all backside idlers should be flat and uncrowned. Backside idlers should be no less than 1.3 times the diameter of the smallest loaded sprocket in the system. To minimize tracking problems, the idler should be located nearest to the sprocket from which the belt is exiting.

EXAMPLE: 10 H.P. Nema B motor with an output speed of 1750 rpm is to drive a centrifugal pump at 1422 rpm. The center distance is approximately 17.5 inches. The service time is 14 hours per day at constant load.

DriveR = Nema B motor, 1-1/4 inch shaft diameter.P1 = 10 HP.n1 = 1750 rpm.

DriveN Machine = Centrifugal Pump, 1-1/2 inch shaft diameter.Minimal shock loading.P2 = Not known. (Assume 10 HP).n2 = 1422 rpm.

Service = 14 hours per day.Center distance = 17.5 inches.

B) Calculation of System Design Horsepower (Dhp)1B) Refer to DriveR (prime mover) table on page 25 to determine the class of the prime mover.

EXAMPLE: Class II

2B) Select the basic service factor (SF) from Basic Service Factors table on page 25 according to the type of driveN machine and class of motor.

EXAMPLE: SF = 1.4

3B) The corrected service factor is now obtained by adding or subtracting the following correction factors;

Cm = correction factor for speed up drives (See Additional Service Factor Speed-Up Drives table page 25.Cf = correction factor for operation conditions (see Additional Service Factor Operating Conditions table page 25).The corrected service factor (SFc) is then calculated as follows:

SFc = SF + Cm + Cf

EXAMPLE: SF = 1.4Cm = +0Cf = +0.2SFc = 1.4 + 0 + 0.2 = 1.6

4B) The Design horsepower (Dhp) is now obtained by multiplying the power to be transmitted by the corrected service factor.Dhp = P1 x SFc

EXAMPLE: Dhp = 10 x 1.6 = 16 DHP

C) Selection of Belt Pitch

The correct belt pitch can be selected from Graph 2, using the design power (Dhp) obtained in step 4B and the rpm of the smaller sprocket (n1).

EXAMPLE: Dhp = 16 HP, n1 = 1750 rpm.Therefore Belt Pitch = 8mm.

SAFETY NOTE � WARNING:USE ONLY RPP® PANTHER® ULTRA-CORD SPROCKETS. THEY ARE SPECIFICALLY DESIGNED TO HANDLETHE HIGH RATINGS IMPOSED BY THE RPP PANTHER ULTRA-CORD BELT.

D) Selection of Belts, Sprockets, and Center Distance

1D) Determine Speed Ratio (K) as follows:

K =n1n2

EXAMPLE: K =1750

= 1.231422

2D) Refer to the Center Distance Selection Table (on pages 46-63) for the selected belt pitch to determine which sprocket combinations give the desired speed ratio. The most suitable sprocket combination can then be selected as follows:

a) By examining the Horsepower Tables (on pages 37-45), eliminate any sprocket combinations which are not capable of transmitting the required power.

b) By examining the Center Distance Selection Table, eliminate any sprocket combination for which the required center distance cannot be obtained with a standard belt size.

iii) The final sprocket combination is then selected based upon the priorities required for the particular drive, in terms of flexibility in driven speed, center distance, drive cost etc...

EXAMPLE: DriveR Sprocket = 26 Teeth, DriveN Sprocket = 32 Teeth, Center Distance = 17.48 in. Belt Length = 1120 mm (140 Teeth), Belt Pitch = 8mm.

3D) Check that the ratio of the number of the teeth on the belt to the number of teeth on the sprocket is not a whole number. If this is the case alter the drive if possible, otherwise the belt life could be reduced.

EXAMPLE: Ratio is not a whole number.

140= 4.375

32

140= 5.385

26

28

4D) Determine the teeth in mesh factor (Cd).Determine the number of teeth in mesh on the smaller sprocket (nt) by using the following formula:

nt = [ 0.5 - (D-d) ] x n6L

where:L = Center distance (in.)n = Number of teeth on small sprocketD = Pitch diameter of large sprocket (in.)d = Pitch diameter of small sprocket (in.)

The number of teeth in mesh (nt) is then used to find the teeth in mesh factor (Cd).If nt is greater than six, then Cd = 1If nt is less than six, then the value of Cd must be obtained by consulting Teeth in Mesh Factors table on page 30.

EXAMPLE: nt = 12.85, therefore Cd = 1.0

E) Required Belt Width

1E) From the Horsepower Table the horsepower rating (Hp) for a particular belt pitch and width can be obtained by selecting the value corresponding to the number of teeth and the rpm of the smaller sprocket.

EXAMPLE: Z1 = 26 teeth, n1 = 1750 rpm. Therefore Hp = 23.53 (at 1750 rpm) for a belt width of 35mm


2E) Multiply the horsepower (Hp) for the belt by the belt length correction factor (KL - in Center Distance Selection tables pages 46-63), to obtain the actual power rating (Hpa) of the belt.

EXAMPLE: KL = 1.0, and Cd = 1.0; therefore Hpa = 23.526 x 1.0 x 1.0 = 23.526

3E) The final step is to calculate the actual drive system service factor (SFa).This is accomplished by comparing the original input motor horsepower (P1) from step A to the actual power rating of the selected belt (Hpa):

SFa = HpaP1

EXAMPLE: SFa = 23.526 = 2.3510

4E) The corrected service factor (SFc) in step 3B was equal to 1.6 while the actual service factor (SFa) is equal to 2.35. This positive comparison provides assurance that the drive design just completed exceeds the input requirements and should yield excellent durability.

F) Bushing Requirements:Determine bushing requirements to fit selected sprockets and shaft diameters as shown in the input data. Tables on pages 16 through 21, contain the necessary data for these determinations.

G) Selected Material Components:

EXAMPLE:DriveR sprocket = 26PTH8-35MPB (1 1/4 Bore)DriveN sprocket = 32PTH8-35QT (QT 1 1/2 Bushing)Belt = 1120PTH8M-35Center distance = 17.48”

INSTALLATION AND TENSIONING ALLOWANCESCenter distance allowances for an RPP PANTHER ULTRA-CORD Belt drive are necessary to assure that the belt can beinstalled without damage and then tensioned correctly. The standard installation allowance is defined as the minimumdecrease in center distance required to install a belt when the flanged sprocket is removed from the shaft for belt installa-tion. This value is shown in the second column of Table 13. If this minimum value is not available consult Engineering fordesign consultation. This table also lists the minimum increase in center distance required to assure that a belt can beproperly tensioned.

The shortest center distance for each sprocket combination (Center Distance Selection tables), may not fully accommodatethe values in Table 13 due to potential sprocket interference.

If a belt is to be installed over flanged sprockets without removing the sprockets, the additional center distance allowancenecessary for installation is shown in Table 14. This value must be added to the allowance shown in Table 13.

DRIVE INSTALLATION AND ALIGNMENT

Table 13 - Center Distance Allowance Table 14 - Additional Center DistanceFor Installation and Tensioning Allowance

Reduce the center distance by the amount shown in Tables 13 and 14 or change the idler position so that the belt can bepositioned on the drive with ease. When installing the belt, never force it over the sprocket flange. If necessary, removethe smaller sprocket from the shaft.

NOTE: RPP PANTHER ULTRA-CORD belts are constructed to attain proper pitch dimension when subjected to tension.For this reason, the belt may not fully engage in large diameter sprockets without applying tension to the belt.Shafts must be correctly aligned (parallel). Misalignment causes uneven pressure on the teeth of the belt, uneven loadingof the tensile member and extreme edge wear on the belt which can result in premature belt failure.

Sprocket axes must be aligned and alignment maintained to prevent the belt from riding against the flanges or over theedge of the flangeless sprocket. The mounting attachments of the driveR and driveN should be rigid enough to preventchanges in sprocket alignment or drive center distance as the load is applied to the drive.

Mounting procedures, which are included with sprockets and associated bushings, should be followed to insure propermounting. Bushings are easy to install and remove. They are the split through flange and taper design which provides atrue clamp on the shaft that is essentially equivalent to a shrink fit. Bushings have a very gradual taper (3/4 inch taper perft. on the diameter). The result is that it securely clamps the shaft with extreme holding power.

NOTE:Care should be taken to use no lubrication on the shaft, sprocket or bushing in order to prevent possible slipping on theshaft or possible bursting of the sprocket through excessive force created by the taper of the bushing. Also, cap screwtorque limitations should be adhered to in order to prevent damage.

RPP PANTHER ULTRA-CORD Installation & Tensioning

32

TENSIONING PROCEDUREWhen installing a RPP PANTHER belt, the belt tension is chosen so as to avoid the problems listed below:

i) TOOTH JUMPAssure that the belt is tensioned adequately to prevent tooth jump under the most severe load conditions that the drive will encounter.

ii) EXTREMELY HIGH BELT TENSIONAvoid extremely high tension which results in elevated noise levels and reduced belt and bearing life.

METHOD 1: STANDARD RPP PANTHER BELT INSTALLATION AND TENSIONING PROCEDURE

The procedure for determining the correct belt tension, is as follows:

A. Calculate the installation tension (Ts).B. Calculate the nominal deflection force (Fnom).C. Calculate or measure the free span length (t).D. Determine the deflection distance (def).E. Measure the actual deflection force (Fact).F. Compare the actual deflection force (Fact) to the calculated nominal deflection force (Fnom).

The application of the installation tension is based on measuring the force required to deflect one span ofthe belt by a given amount as shown in Figure 7 below. Completion of steps A through F are necessary tocomplete proper tensioning.

A - Installation TensionCalculate the installation tension (Ts) using the following formula:

Ts (lbs) = 81938 * HPDia. * RPM

Where: HP= Motor base horsepower.Dia. = DriveR sprocket pitch diameter (inches).RPM = DriveR sprocket speed.BW = Belt Width (mm).Mass = Mass Factor (Obtained from Table 16).

Note: Ts must be compared with the minimums listed in Table 15

B - Nominal Deflection Force

Calculate the nominal deflection force (Fnom) required to attain the above installation tension (Ts):

Fnom (lbs) = Ts16

EXAMPLE: 181.3 = 11.3 lbs16

C - Free Span Length

Calculate the free span length (t) of the belt. This value can be determined by:

t (in) = L2 - (D-d)2

2

Where: L = Center distance (inches)D = Pitch diameter of large sprocket (inches)d = Pitch diameter of small sprocket (inches)

t (in) = (17.48)2 - (3.208 - 2.607)2

t = 17.477 inches

D - Deflection Distance

Determine the deflection distance by:def (in) = 0.0156 (t).Where (t) = free span length (inches).

EXAMPLE: def (in) = 0.0156 x 17.477def (in) = 0.27 inches

E - Measure Actual Deflection Force

With the belt installed on the drive and tensioned to a level required to eliminate all slack in the system (snug fit)begin the tensioning procedure. At the center of the belt span to be tensioned, apply a force equal to the deflectionforce calculated previously in step B. This force is applied perpendicular to the span so as to deflect the belt by theamount equal to (def) calculated in step D. For belts wider than 2.0 inches, place a section of rigid member (such askey stock) across the belt width to prevent belt distortion and insure proper tensioning. Be sure that either the driveRor driveN sprocket is free to rotate.

F - Deflection Force Comparison

Compare the actual force (Fact) necessary to deflect the installed belt at the center of the free span by theamount calculated in step B. If the measured force (Fact) is greater than 1.10 times the calculated force (Fnom),the belt is too tight. If the measured force (Fact) is less than 0.90 times the calculated force (Fnom), the belt istoo loose. In both cases a tension adjustment is necessary.

METHOD 2: SIMPLIFIED RPP PANTHER BELT INSTALLATION AND TENSIONING PROCEDURE

Table 17 presents the nominal center distance and take up allowance required to install and tension RPP PANTHER belts under the following conditions.

Condition A - one flanged sprocket and one unflanged sprocket. When sprockets have been mounted and properly aligned, put belt over flanged sprocket first, then slip it onto the unflanged sprocket. As indicated before,in that RPP PANTHER belts are designed to transmit extremely high loads, the complete engagement of the beltin large diameter sprockets may require the application of tension during installation. Tension belt by adjustingcenter distance or by using an idler if center distance is fixed.

Condition B - both sprockets flanged. Put belt over larger sprocket first, then over smaller sprocket. Tension beltby adjusting centers or by adjusting tensioning idler.

Condition C - minimal center distance adjustment. Mount one sprocket on shaft loosely and put belt on sprock-et. Put other sprocket into belt loop and slip the sprocket onto the other shaft. Move whole drive into proper posi-tion and alignment and secure sprocket to shafts. Tension belt by adjusting center distance.Less allowance for installation and take-up may be possible. This can be determined by a summation of require-ments in Tables 13 and 14, page 20

NOTE: DO NOT PRY OR OTHERWISE FORCE BELTS ONTO SPROCKETS AS THIS CAN RESULT IN PERMANENTDAMAGE TO THE BELT.

Table 17 - CENTER DISTANCE ALLOWANCE

NOTE: For drives with shock loadingor other unusual conditions, the force may have to be increased for proper operation of the drive.

BELT TENSION

RPP PANTHER Belt Drives do not require as much tension as other belt drives that depend on friction to trans-mit the load. The installation procedure should begin by installing the RPP PANTHER Belt with a snug fit, neithertoo tight nor too loose. After the belt has been so tensioned, a force to deflect the belt by a certain amount toassure proper tension can be measured. Measure the belt span (t) as shown in Figure 7. With one sprocket freeto rotate, use a spring scale to apply a perpendicular force to the center of the belt width at the mid-point of thebelt span. For belts wider than 2”, it is suggested that a strip of keystock, or something similar, be placed acrossthe belt under the point of force to prevent distortion.

Measure the force required to deflect the belt 1/64” for each inch of belt span. For example, the deflection for a32” belt span is 32 x 1/64 = 1/2” deflection. The force required to deflect the belt this amount at the proper ten-sion is listed in Average Tensioning Values tables on pages 35 and 36.

NOTE: Utilization of the simplified tension procedure (Method 2) may not result in ultimate belt life due to deflection forces in Average Tensioning Values table being less accurate than the nominal deflection force calculated in Method 1.

Engineering Data

SPROCKET DIAMETER AND SPEED

Blanks in the Belt Horsepower Rating tables indicate therim speeds exceed the safe operating speed of 6500 feetper minute for cast iron sprockets. For rim speedsgreater than 6500 feet per minute, contact CarlisleEngineering for other recommendations.

FLANGED SPROCKETS

Due to tracking characteristics, even on the best aligned drives, all synchronous belts have a tendency tomove axially and will ride off the edge of the sprockets.In order to keep the belt on the sprocket, side flanges are needed.

On all synchronous drives the following conditionsshould be considered when selecting flanged sprockets.

1. Two Sprocket Drives: One sprocket must haveflanges on both sides or both sprockets must haveone flange but on opposite sides.

2. Long Center Drives: When the center distance isequal to or greater than eight times the small sprocket diameter, both sprockets should be flanged.

3. Vertical Shaft Drives: One sprocket should beflanged on both sides, and all other sprockets in thedrive system should have one flange on the bottomside.

4. Multiple Sprocket Drives: Every other sprocket in thesystem should be flanged on both sides or one flange on each sprocket alternating sides around theentire system.

On many synchronous drive applications, you won’t haveto be concerned about flanged sprockets, because mostof the smaller sprockets (up to and including 80 teeth)are already furnished with flanges on both sides of thesprocket. A flanged sprocket is identified by a letter “F”in the type column in the stock sprocket dimensionaltables.

Safety Note � WARNING!FAILURE TO FOLLOW RECOMMENDED APPLICATIONINFORMATION AND RECOMMENDED PROCEDURES FORINSTALLATION, CARE, MAINTENANCE AND STORAGE OFBELTS MAY RESULT IN FAILURE TO PERFORM PROPER-LY AND MAY RESULT IN DAMAGE TO PROPERTY ANDSERIOUS BODILY INJURY. MAKE SURE THAT BELTSSELECTED FOR ANY APPLICATION ARE RECOMMENDEDFOR THAT SERVICE.

FIXED CENTERS(NO ADJUSTMENT)

True fixed center applications are those where no provision has been made to adjust either the driveR ordriveN shaft. Fixed centers are not recommended forany synchronous belt drive other than motion transfer(low or no torque) drives. Fixed center applications implythe need for exact tolerances. Although length tolerances for synchronous belts are considerably lessthan those for other belts, such as v-belts, etc., no beltcan be manufactured without some tolerance. Sprocketmanufacturing tolerances also contribute to fixed centerdrive problems. Fixed center applications do not allow for proper belt installation and tensioning practices and prevent accepted maintenance procedures.

Because fixed center applications prevent proper beltinstallation and tensioning procedures, reduced belt performance can result. Through the use of an idler, theproblems associated with fixed center drives can be eliminated. See engineering section on use and application of idlers.

IDLERS

The use of an idler should be limited to those applicationswhere it is absolutely necessary, such as fixed centerdrives. A common serious fault is the use of idlers whichare too small. The use of such idlersintroduces severe bending stresses in the belt resultingin reduced belt life.

An idler may be located on either the inside or outsideof the belt drive, but in either case should be on the slackside (lower tension belt span). An inside idler (groovedsprocket) should not be smaller than the smallest loadedsprocket in the drive system. A flat, uncrowned, idler pul-ley may also be used on the inside as long as its diameteris equivalent to the diameter of a 40 groove sprocket, ormore.

Outside idlers are always flat, uncrowned, pulleys.Diameters should be a minimum of 1.3 times larger thanthe smallest loaded sprocket in the system. Arc ofcontact shouldbe kept to a minimum to reduce the reverse bendingstresses on the belt.

Spring-loaded idlers are not recommended for usewith synchronous belt drives. This is due to the abilityof synchronous belts to self-generate sufficient tensionto overcome any reasonable spring force. The belt willjump teeth in this situation because the effectivenessof the spring has been eliminated. Additional springforce will only impose higher belt tension which may beexcessive and dramatically reduce the belt life.

Synchronous Drive Systems Installation

The synchronous belt drive will perform successfully when proper installation procedures are followed.

SPROCKET INSTALLATION

1. Thoroughly inspect the bore of the sprocket and thetapered surface of the bushing. Any paint, dirt, oil orgrease must be removed.

2. Assemble bushing into sprocket. Loosely insert thecapscrews into assembly, but do not lubricate capscrew threads. (Note: Install M thru S bushingsso the two extra holes in the hub are located as far aspossible from the bushing’s sawcut.)

3. With key in keyseat of shaft, slide sprocket to itsdesired position with capscrew heads to the outside.(A few small sprockets may have to be installed withthe capscrews on the inside.) If it is hard to slide thebushing onto the shaft, wedge a screwdriver bladeinto the sawcut to overcome the tightness.

4. Line up assembly so as not to misalign belts, and tight-en capscrews evenly and progressively. Apply the rec-ommended torque to capscrews. There should be 1/8”to 1/4” gap between the sprocket hub and the bushingflange. If gap is closed, the bushing is oversized andthe next smallest bushing should be used.

SPROCKET ALIGNMENT

Sprocket alignment and parallelism of the shafts are veryimportant. Proper alignment helps to equalize the loadacross the entire belt width, thereby reducing wear andextending belt life.PLACE A STRAIGHTEDGE against the outside edge of

the sprockets and move sprockets until the straightedgetouches the two outside and two inside edges of sprock-ets. The straightedge should cross the sprockets as nearthe shafts as possible. A string can be used if a straight-edge is not available. Remember the string should con-tact at four points as explained above.

After aligning the sprockets, check the rigidity of thesupporting framework. Shafts should be well supportedto prevent distortion and a resulting change in the centerdistance under load. Do not use springloaded or weight-ed idlers. Idler sprockets or pulleys must be locked intoposition after adjusting belt tension.

Please note: at least one sprocket must have a flange.

An alternate method can be used to properly tension thebelt on a synchronous drive. After the drive has beeninstalled and tension applied, the deflection force can bemeasured to verify the proper tension. Stop the driveand measure the belt span (see sketch). Using a springscale, apply a perpendicular force to the exact center ofthe belt width and near the center of the belt span.Measure the force required to deflect the belt 1/64 inchfor every inch of span length. For example, the deflectionfor a 32 inch span would be 1/64 multiplied by 32, or 1/2inch.

Actual installation tension required depends on peakloads, system rigidity, number of teeth in mesh, etc. Fordrives with shock loading or other unusual conditions, theforce may have to be increased for proper operation ofthe drive.

Note: For belts wider than 2 inches, it is suggested thata rigid strip of keystock or something similar be placedacross the belt between the point of force and the belt toprevent belt distortion.

Safety Note �WARNING!FAILURE TO FOLLOW RECOMMENDED APPLICATIONINFORMATION AND RECOMMENDED PROCEDURES FORINSTALLATION, CARE, MAINTENANCE AND STORAGE OFBELTS MAY RESULT IN FAILURE TO PERFORM PROPER-LY AND MAY RESULT IN DAMAGE TO PROPERTY AND SERIOUS BODILY INJURY. MAKE SURE THAT BELTSSELECTED FOR ANY APPLICATION ARE RECOMMENDEDFOR THAT SERVICE.

BELT INSTALLATIONDo not pry or otherwise force the belt onto the sprockets, as this can result in permanent damage to thebelt. Either remove the sprocket’s outside flange orreduce the center distance between the pulleys so thatthe belt can be easily installed.

Synchronous belts are not to be tensioned as you woulda V-Belt or any other belt that depends on friction totransmit the load. They should be installed with a snugfit, neither too taut nor too loose.
