General
Function of Slew Drive
Slew drives comprise a highly robust Slewing Ring provided withgear teeth (1), one or several toothed drive elements (2), a wormgear in this case, seal (3), housing (4) and a hydraulic or an electricdrive (5). Slew Drives are designed for grease lubrication.
In a Slew Drive the rolling elements (6) carry the load between theinner ring (7) and outer ring (8). The raceway system’s capacity isdetermined predominantly by Slewing Ring design, the depth ofhardening and the number and size of the rolling elements. Spacers(9) separate the rolling elements and minimise friction and wear.

Load distributionDepending on external load, the load distribution contact and theangle around the rolling elements will vary.
In the case of axial load, all rolling elements are loaded in the samedirection.In the case of radial load, a segment of the rolling elementscarries the load.In the case of tilting moment load, a segment on one side and asegment on the opposite side carry the load.Mostly, a combination of axial, radial and tilting moment loadsoccur.

“Compressive” loads
“Suspended” loads
Radial loads must be transmitted by means of frictional contactbetween Slew Drive and the attached structure.
A good bolt connection is vital for satisfactory function of theSlew Drive. Bolt connection and tilting clearance of a Slew Drivemust be checked regularly.
•
•
Axial loads can be “compressive“ or “suspended”.
A “suspended” axial load and the load on a rising segment intilting moments must be adequately resisted by mounting bolts.
•
•
GearSlew Drives of series WD are designed with worm gear.Slew Drives of series SP are designed with spur gear. Permissibletorque is specified in the Technical Information section.
DriveDrive is provided by either an attached hydraulic or electric motor.Both motor mountings as well as the shaft/hub connection conformto industrial standards, hence hydraulic motors available on themarket can be mounted without difficulty.For electric motors, corresponding adapter pieces are necessary. Thedesign specification for drive motors is undertaken by IMO, basedupon rotational speed and torque information provided by thecustomer.
HousingHousing is designed as a welded or cast component and adaptedto the size of the Slew Drive. As a standard feature, housings aresupplied with a priming paint.
All catalog bolt data is valid only for “compressive” loads!
SealingPolymer seals protect the Slew Drive from normal dirt penetration,dust and light sprayed water. For very dirty and wet environments,the seals shall be protected with pre-mounted labyrinth seals on themounting structure.Performance and reliability of a Slew Drive depend strongly onavoiding ingress of contaminents to the interior of the unit.
Pressure washing must not be used to clean Slew Drives.
Operating temperatureStandard version IMO Slew Drives can be used in ambienttemperatures from –20°C up to +70°C.
Selection criteria
The following criteria must be considered for the correct selectionof a Slew Drive.
Position of the output shaftVertical: Slew Drives of all series can be used
(even with a self-locking gear).
Horizontal:
Alternating:
All Slew Drives can be used with the exception of theWD-H series and WD-L series sizes 0478 and 0625.Here, it is necessary to use a Slew Drive with a 2-startgear, since using gear with self-locking and externaldriving force does not ensure smooth (jerk free)operation.
Slew Drives provided with self-locking gear cannot beused. Using a Slew Drive of series WD-H with 1-startgear without self-locking is possible only up to 5°inclination angle to the vertical, otherwise smoothoperation cannot be guaranteed.
Slew Drives that are not self-locking can, as an option, be equippedwith a locking brake, if required.
LoadsExternal forces such as axial load, radial load and tilting momentmust lie below the static limiting load curve, as regards their operatingload point. For this, please refer to the chapters “Static capacity ofraceway“ and “Mounting bolts”.
Shocks, vibrationsTo account for the peculiarities of different applications, the shockfactors for gears should be considered. Slew Drives of the series WDare not suitable for applications under permanent vibration.
Back loadKeep in mind that in the case of series WD Slew Drives, due to thehigh gear ratio, that in the case of back load (e.g. caused by boomimpacting on obstacle), there is danger of irreparable damage tothe worm gearbox, so long as the driving torque exceeds themaximum permissible table values Md max.
Caution: Catalog bolt data is not valid in this case!

TorqueThe operating torque may not exceed the maximum torque specifiedin the Technical Data section, calculated with application servicefactor 1. Explanations of different torque specifications are as follows:
Series SP:
Maximum torque Md max:Slew Drive series SP-H, SP-M:Maximum torque is limited by maximum radial load ofthe planetary gear-set used.
Slew Drive series SP-I:The maximum torque is limited by the input torque ofthe attached hydraulic motor and the strength of theparallel key connection for a 25 mm shaft.
Nominal torque Md nom:The nominal torque is calculated with a safety factoragainst tooth base fatigue SF1, at the rotational outputspeed specified in the Technical Data section, under one-way varying load.
DutySlew Drive series WDs are designed for intermittent duty. Applicationwith continuous running or with higher rate of duty andsimultaneously high output torque are not permissible.This would lead to unacceptable temperature increase in the gearingand thus to premature failure of the Slew Drive.Transmission of the maximum torque is to be limited to 10% ofeach minute. Please check the diagram for the maximum permissibleduty per minute of the respective series on P. 49 and P. 59.
Static capacity of raceway
Static capacity of the Slew Drive is determined by:
• Hardening depth of the raceway• Number and size of the rolling elements• Slewing Ring design• Raceway geometry
The limiting load diagram shows permissible axial and tilting momentloads for a respective size unit.
Every loading case including the required or recommended safetymust lie below the limiting load line.Series WD:
Maximum torque Md max:The calculation of the maximum torque with a safetyfactor against tooth fracture SFS 1 is done according toG. Niemann / H. Winter, Machine Elements, Band III, 1986,for worm gears and is influenced by:• Limiting value of tooth base stress• Module• Gearing width
Nominal torque Md nom:The nominal torque is calculated with a safety factoragainst tooth wear of SF1,• at the output speed specified in the table• for a calculated service life of 10000 h• at a duty of 5%For Slew Drives with two motors, the specified values arevalid for a slewing angle of � 170°.
Series SP and WD:
Maximum holding torque Mh:The maximum holding torque determines which retroactivetorque can be transmitted or held without damage beingcaused to the gearing. In general, the value of themaximum torque is assumed.
Rotational speedSlew Drive series SP:The maximum permissible speed is
Slew Drive series WD:The maximum permissible speed is specified in the Technical Datasection. For higher speeds, our Engineering Department shouldbe consulted.

To address the peculiarities of different applications, the followingapplication service factors are to be considered in the prevailingloads:
Application service factors are to be considered in the followingequations for the prevailing loads:
Slew Drive: pre-selected SP-M 0741/2-05894
The following values are achieved with an application servicefactor of 1.25:
FaxD = Fax • fa
MkD = (Mk + 1.73 • Frad • ) • faDL

To account for the prevailing radial load, the tilting moment isincreased accordingly.
This equation applies only if:
Frad � 220 • + 0.5 • FaxMk
1000
Should the value be exceeded, the limiting load diagram no longerapplies.Please contact our Engineering Department.
Calculation example:
Application:
Load:
Slewing equipment for a constructionmachine under normal operation
Axial loadRadial loadTilting moment load
55 kN6 kN86 kNm
FaxD = 55 • 1.25 = 68.75 kN
MkD = (86 + 1.73 • 6 • ) • 1.25 = 117.11 kNm7411000
At this point it can be verified in the limiting load diagram, whetheror not the pre-selected Slew Drive is statically adequate.
If the operating load point lies below the limiting load line then theSlew Drive is statically adequately dimensioned. If loads frequentlyoccur during the slewing process, the selected type should bereevaluated dynamically for lifespan. For this, please contact ourEngineering Department.
Mounting bolts
Prevailing loads must be safely transmitted. To ensure this, mountingbolts should be sized to handle the raceway loading.The bolt curve is depicted in the static limiting load diagram, subjectto the following conditions:
Caution: In the case of “suspended” loads, the bolts are subject toadditional tensional forces.Please contact our Engineering Department.
Static load carrying capacity of mounting bolts
Determining the operation load level, both with and without radialload, occurs along with the verification of the static load carryingcapacity of the raceway.
If the prevailing load case lies below the limiting load line in thestatic limiting load diagram then the bolt connection is staticallyadequately dimensioned.

For tightening torques.For Slew Drives with through holes, use the largest possible metricbolts with regular threads.

Friction torque
The friction torque in Slew Drives depends upon many influencefactors, e.g.:• Rigidity and flatness of the mounting structure• Load and loading combination• Rotational speed and operating temperature• Design of Slew Drive• Number and frictional torque of seals• Lubrication grease and level of filling• Manufacturing tolerances• Other factors
The friction torque of an unloaded Slew Drive can be determinedapproximately with the following equations:
Slew Drive series SP, with minimum Slew Drive clearance greaterthan zero
MwA = 0.2 •DL2
2000
Slew Drive series WD-L, with preloaded Slew Drive
MwA = 2.0 •DL2
2000
Slew Drive series WD-H, with preloaded Slew Drive
MwA = 4.0 •DL2
2000
Dynamic load Slew Drive capacity of mounting bolts
Mostly, static dimensioning of a mounting bolt is sufficient.In cases where very high numbers of stress reversals act on the SlewDrive, dynamic verification is necessary. For this, please contact ourEngineering Department.
Pressure lock of mounting bolts
When radial loads act on the Slew Drive, it must be ensured thatthese loads can be transmitted without shearing forces occurringinside the bolts. Therefore, it must be determined whether theradial load can be transmitted via frictional contact between themounting structure and the Slew Drive.
nb = number of fixing holes per ringFsp = pre-stressing force on a mounting bolt
If the prevailing radial load exceeds the limit value, we request thatyou contact our Engineering Department.
Frad max =nb • Fsp
18.8
For Slew Drives with a different number or size of bolts in the innerand outer ring, the permissible radial load is to be determined forboth rings. The smaller value is the limiting value.Frictional contact prevails if Frad max is greater than the prevailingradial load.
Slew Drives, series WD-H, are basically to be centralized.
Securing the mounting bolts
When a customer desires that the mounting bolts be secured, werecommend the following products (manufacturer specification isvalid):
Loctite®
Application of Loctite 270 is suitable for the highest level ofconnections. This prevents loosening and the threads are also sealed.
Nord lock®
Nord lock, self-locking washers, are recommended for cases ofvibration or dynamic loading cycles. Due to a pair of square taperedwashers with tapered surface gradients between both Nord-locksecuring washers greater than the gradient of the bolt threads, anyloosening tendency of the bolt is immediately prevented.
Other bolt securing systems are not recommended.
The friction torque for a Slew Drive under load can be determinedwith the following equation, approximately:
Mw = 0.005 • (4400 • Mk + 4 • DL • Frad + DL • Fax) + MwA
Gear
Slew Drive series SP
Type of gear
Slew Drives series SP are provided with spur gear according toDIN 3960, DIN 3962 and DIN 3967.If higher torque is necessary or longer operating lifespan is required,it is possible to manufacture the gear in tempered or hardened form.
Permissible torqueCorresponding data is available in the Technical Information section.
Drive pinionThe pinions used in different sizes are provided with hardened gear.In the Technical Data section you will find data about transmissionratios and numbers of teeth.The drive pinion in direct drive units is supported by two radialbearings integrated into the housing and the drive mount.
40
Technical Information
LifespanThe expected lifespan of the gear depends on the operating conditions.The following factors are key:• Torque• Output speed• Duty factor• Ambient temperature, etc.
Lubrication
To ensure flawless operation and long usable life, adequate andregular lubrication is necessary. The grease fulfills the followingfunctions:
For the raceway:
• Reduction of friction and wear in the rolling contacts• Corrosion protection• Lubrication of seals• Additional sealing effect of the grease “collar”
For the gears:• Smooth running• Less wear• Reduced operation noise• Longer operating life• Less heat development
Initial greasing
IMO Slew Drives are supplied pre-lubricated. High-quality lithium-complex grease, based on mineral oil, with EP-additives accordingto DIN 51825, KP2P-20 is the standard lubrication.
Regreasing intervalsRegreasing must be done at regular intervals, depending on frequencyof use and ambient operating conditions. General attention mustbe paid to ensure that the grease used during the greasing iscompatible with the sealing material. Special attention should bepaid to ensure that lubricating grease types originally specified areused throughout the life of the unit.Should you wish to use other types of grease, it must be verifiedwhether the grease is compatible with that used for initial greasing.Please contact your grease manufacturer.Please observe also the data in the “Installation and MaintenanceInstructions” chapter.Beside regular regreasing during operation, it is also necessary togrease the Slew Drive after long standstill periods. Equally importantis to grease the equipment in which the Slew Drive is integratedafter cleaning.
Tooth backlashTooth backlash is factory-set at the highest point of the gear. Itdepends on the module of the gear and is calculated according tothe following formula:
Tooth backlash to be set = 0.03 to 0.04 • module
Slew Drive series WD
Design of the gearSlew Drive series WD is designed with a hardened worm gearaccording to DIN 3960, DIN 3962 and DIN 3967,
Permissible torqueCorresponding data is provided in the published Technical Informationsection.
Worm shaftWorm shafts are made of hardened steel, with ground tooth flanks.
Tooth backlashThe tooth backlash is set at approx. 0.3 mm for Slew Drive seriesWD.
Self-locking
Series SP Slew Drives
Series SP Slew Drives are not self-locking.
Series WD Slew Drives
Self-locking only exists in the case of series WD Slew Drives if itcannot be driven from the output side. Self-locking is directly relatedto the efficiency of the Slew Drive, which depends on very manyfactors, e.g.
• Lead angle• Angle of friction• Rotation speed• Lubrication• Material matching• Surface finish, etc.
Theory indicates self-locking occurs if the gear efficiency is < 50%.Data in the Technical Data section conforms to this statement.However, it is vital to determine the actual existence of the self-locking characteristics in the supplied Slew Drive individually duringactual usage.We take no responsibility for conformity of the theoretical data inthe Technical Data section with the practically prevailing self-lockingor non-self-locking characteristics.
Shock coefficientAs for the applications in which impact is expected, the appropriateimpact coefficients must be considered when determining the SlewDrives’ maximum torque rating.

Please follow the Installation and Maintenance Instructions.Following the Installation and Maintenance Instructions is importantfor the reliability and safety of our product and has considerableinfluence on its service-life. The latest revision of the Installationand Maintenance Instructions can be downloaded at www.imo.de.Contact us to receive a paper copy.
ATTENTION:Slew Drives must not be cleaned with pressure washingequipment. During pressure washing, large amounts ofpressurized water can penetrate into the Slew Drive throughthe sealing gap and cannot be removed, even by massive re-greasing. This will strongly reduce the usable lifespan of aSlew Drive.
Mixing greasesGrease with different thickener and base oil should generally notbe mixed. The manufacturer should always confirm if different greasetypes can be mixed.
Shelf life of lubricantsLubricants are subject to ageing even if unused. If after 3 yearsgrease is not yet used, it should be replaced.
Design of mounting structure
Safe transmission of application loads and reliable operation of SlewDrives is achieved, along with other factors, through using adequatelydesigned mounting structures.To ensure safe operation of Slew Drives, there are certain minimumrequirements to the mounting structure.
• Sufficient rigidity (see “Installation and Maintenance Instructions”)• Maintain flatness according to “Installation and Maintenance Instructions“• No hard points (e.g. through cross beams)• Surfaces for bolts must be machined plane• Hollow mounting structure is preferred• Use all mounting bolts• Bolts of recommended strength should be used• Minimum strength of attached structure 500 N/mm2
Very different mounting structure solutions can be used, dependingupon maximum load and application.If hollow mounting structure is designated for attached structure,flange thickness should be at least 50 % of Slew Drive’s overallheight. The thickness of the hollow mounting structure should beabout 30% of flange thickness. For weight-critical applications,flange thickness can only be reduced if appropriate stiffening ribsare provided and the specifications on permissible flatness andperpendicularity deviations and deformation under load are upheld.Values on this are specified in the“Installation and Maintenance Instructions“.

Technical Information
Typical selection:Worm gear driven types have proven themselves as steeringgears. Features such as high torque, low output rotary speedwith smaller assembly height and diameter clearly speak for theapplication of WD design. The smallest assembly height of aworm gear driven Slew Drive is provided by the WD-L series.
Enables higher output rotary speedsVery narrow in size around the Slewing Ring, but the drive isbroad in axial directionOffers a large, open internal diameterVery suitable for upper structures with larger radial diametersBasically not self-locking in designCan be equipped with locking brakesThe position of output shaft is insignificantPreferred design for vibration and impact loading applications

SP design:
Typical applications:Handling and automation equipment, packaging machines, toolchangers, grippers, construction machines, land and forestry machines,etc.
2. Step: Selecting a suitable design size in the limiting loaddiagram for “compressive” load:
A suitable Slew Drive is selected iteratively. For a pre-selected SlewDrive, (e.g. WD-L 0478/3-04904), an operation load point is calculateddepending on external loading, the application service factor andthe raceway diameter DL.Loading is permissible for raceway and bolt connection, providedthat the operating point lies below the limiting load line of a pre-selected Slew Drive.If the operation load point lies above the corresponding limiting loadline, a Slew Drive with higher power rating must be selected, forwhich the limiting load line lies above the current operation loadline. For the newly selected size, the operation load point must becalculated again and the permissibility of the new operation loadpoint must be verified against the limiting load line.On the contrary, if the operating load point also lies below the limitingload line of a smaller size, then, for this size, permissibility of thenewly calculated operating point can be verified within the limitingload diagram.This iterative approach is repeated until an optimally suitable size isdetermined, by which the operation load point lies below thecorresponding limiting load line.
The following conditions must be fulfilled:

Step 2),the size WD-L 0478/3-04904 selected in Step 2 has to be selected. If the operating torque Md B is greater than 24288 Nm, thenWD-L 0625/3-06290 must be selected; in this example, however, WD-L 0625/3-06290 is not an economical solution.
Step 3: Static reliability verification of operationtorque Md B:
The following condition must be fulfilled:Operating torque Md B � maximum torque Md max(see series overview WD-L P. 48)
Example: 13200 Nm � 24288 Nm (condition fulfilled)

Due to the high gear ratio and the large surface contact between worm and worm gear, very high torque values can betransmitted using very small sized Slew Drives (highest power density). Worm gear driven Slew Drives of the light seriesWD-L are short-cycle drives for rotation and swiveling applications . Use in continuous rotation applications is notpermissible due to higher duty. The duty should be selected so that over-heating around the gearing contact cannotoccur. Diagram 2 exhibits the maximum permissible duty per minute, depending upon operation torque. When thismaximum permissible duty per minute EDmax ’ is exceeded, the permissibility must be checked by the IMO EngineeringDepartment.
The following conditions apply when determining the maximum permissible duty per minute and when verifying the wearcharacteristic of worm gearing:- Output speed: n = 1.0 rpm- Wear safety factor of worm gearing: SW = 1.3- Observance of the maximum permissible duty EDmax ‘ (see diagram 2)- Ambient temperature 20°C
Determining the maximum permissible duty per minute EDmax ‘ :The maximum permissible duty per minute should never be exceeded
Wear characteristics of the worm gearing:

The operation is permissible as regards wear characteristics,if the following relationship prevails:

WD-
H
Due to the high gear ratio and the large surface contact between worm and worm gear, very high torque values can betransmitted using very small sized Slew Drives (highest power density). Worm gear driven Slew Drives of the heavy series,WD-H, are short-cycle units for rotation and swiveling applications. Use in applications with continuous rotation is notpermissible, due to the higher duty. The duty is to be selected so that over-heating around the gearing contact cannotoccur. Diagram 2 exhibits maximum permissible duty per minute, depending upon operation torque. When this maximumpermissible duty per minute EDmax ’ is exceeded, the permissibility must be checked by the IMO Engineering Department.
The following conditions apply when determining the maximum permissible duty per minute and when verifying the wearcharacteristic of worm gearing:- Output speed: n = 1.0 rpm- Wear safety factor of worm gearing: SW = 1.3- Observance of the maximum permissible duty per minute EDmax ‘ (see diagram 2)- Ambient temperature 20°C
Determining the maximum permissible duty per minute EDmax ‘ :The maximum permissible duty per minute may never be exceeded
Wear characteristics of the worm gear:
Gw:Bh:
EDB:Md B:
The application is permissible as regards wear characteristics,if the following relationship prevails:
If this relationship is not fulfilled, a high rate of wear must beexpected.

Verifying tooth base fatigue strength:
Valid for the following conditions:- Output speed: n = 5.0 rpm- Repeated load- Ambient temperature of 20°C
Md B:Md nom:
Operation torque [Nm]Nominal torque [Nm] for SF = 1 and n = 5.0 rpm (see dimensions table)
The operation is permissible as regards the fatigue stress oftooth base, if the following equation is fulfilled.
If this relationship is not fulfilled, then there is imminent dangerof fatigue fracture of the tooth base.
Gw � Bh •EDB100
Fatigue stress of tooth base needs to be consideredhowever, if the following equation is met (if so, referto below additional steps to verify life):
Md B > Md nom
If the following equation is met, the stress levelof tooth base is below the endurance limit andfatigue is infinite:
Md B � Md nom
Gw:Bh:EDB:
Limit value from diagram [h]Operation time [h]Duty [%]
Verification of the pitting and wear safety of tooth flanks must be done by theIMO Engineering Department!

Material tests areperformed accordingto the latest industryrecognized methods(i.e. ultrasonic testing-developed by theFraunhofer Institute).
The quality chain starts with the choice of theraw material (i.e. for the production of seamlessrolled rings of the SP series) and is continuous,including the ongoing testing of the currentproduction series.
IMO Slew Drives have to meet the highest quality requirements
because they are often used assafety critical components.
Development, design, calculationand sales are performed strictlyaccording to DIN EN ISO 9001
certified procedures.
