Functional Description, Section

Gerotor motors are robust hydraulic driveline elements withuniversal applications.

The Gerotor has a special design feature (Gerotor reduction)that allows low output speeds without the need for additionalgear stages. In many cases, this can help to reduce costsand cut down weight.

Gerotor motors are self-lubricating and practicallymaintenance-free, merely requiring a regular oil change.

The Gerotor motors cover a torque spectrum from 10 daNmto 100 daNm and operate in a power range from 10 kW to30 kW.

Mode of operation:Gerotor motors are internally geared motors that converthydraulic energy into mechanical energy.

The Gerotor consists of a ring with an internal gear profile,and an excentric pinion mounted in this internal ring gear. Thepinion has one tooth less than the internal ring gear and soonly advances by one tooth space every time it rotates withinthe ring. This results in the speed reduction which ensures

good low-speed characteristics and high output torques.

A cardan shaft with crowned profile on either end transmitsthe power from the pinion to the output shaft.

Series GMS and GMT motors are controlled using a rotatingdisc valve driven by a second, shorter cardan shaft.

Motor torque is dependent on the size of motor (cc perrevolution) and the pressure differential between the inlet andoutlet connections.

Variants

The motors offers a wide choice of special versions for particularapplications in addition to its comprehensive range of standardmotors.

– Wheel motors with recessed mounting flange

– Short motors for use with gearboxes

Permissible shaft load for GMS, GMSWThe tapered roller bearings on the output shaft mean it canaccept high levels of axial and radial shaft load.

Radial load starting characteristics are considerably betterthan motors with plain bearings.

The broken curve plots the maximum permissible radial load.Loads above and beyond this level can lead to breakage.

The central solid curve plots the permissible radial loads fora theoretical service life (B10) of 3000 hours at 200 min-1.The expected service life can be calculated for differentspeeds and/or radial loads.

Please refer to the "General information" brochure for moredetailed information about the caculation methods.

These data assume the use of a hydraulic fluid with asufficient anti-wear additive content.

Details of internal toothing

GMSS is a GMS motor without the output shaft and bearings.It is designed for direct mounting onto a gearbox that alreadyhas its female input shaft in bearings.

The cardan shaft of the GMSS describes a tumbling motion.Consequently, the motor itself cannot be fitted with a shaftseal. The add-on component (gearbox) must be fitted with ashaft seal on its input end in order to prevent the motorleakage oil from flowing into the add-on unit.

The maximum permissible backflow pressure (pressure in themotor leakage oil line ) is dependent on the loading capacity

of the shaft seal. We always recommend fitting a leakage oilline.

The gearbox input must be designed so the leakage oil fromthe motor lubricates the cardan shaft profile and the bearings.Route the leakage oil line so lubrication to the motor is stillassured when it is stopped. Use the tapered sealing ringsupplied with the motor in order to direct the leakage oil to thelubrication.

Fill the GMSS with hydraulic fluid through its leakage oilconnection before taking the motor into operation.

Permissible shaft load for GMT, GMTWThe tapered roller bearings on the output shaft mean it canaccept high levels of axial and radial shaft load. Radial loadstarting characteristics are considerably better than motorswith plain bearings.

The broken curve plots the maximum permissible radial load.Loads above and beyond this level can lead to breakage. Thecentral solid curves plots the perissible radial loads for atheoretical service life (B10) of 3000 hours at 200 min-1.

The expected service life can be calculated for differentspeeds and / or radial loads.

Please refer to the "General Gerotormotors" brochure formore detailed information about the calculation methods.

These data assume the use of a hydraulic fluid with asufficient anti-wear additve content.

RE 14 060/03.96


GMTS-assembly, leakage oil connection and add-on components (Dimensions in mm)

GMTS is a GMT motor without the output shaft and bearings.It is designed for direct mounting onto a gearbox that alreadyhas its female input shaft in bearings.

The cardan shaft of the GMTS describes a tumbling motion.Consequently, the motor itself cannot be fitted with a shaftseal. The add-on component (gearbox) must be fitted with ashaft seal on its input end in order to prevent the motorleakage oil from flowing into the add-on unit.

The maximum permissible backflow pressure (pressure in themotor leakage oil line ) is dependent on the loading capacity

of the shaft seal. We always recommend fitting a leakage oilline.

The gearbox input must be designed so the leakage oil fromthe motor lubricates the cardan shaft profile and the bearings.

Route the leakage oil line so lubrication to the motor is stillassured when it is stopped. Use the tapered sealing ringsupplied with the motor in order to direct the leakage oil to thelubrication.

Fill the GMTS with hydraulic fluid through its leakage oilconnection before taking the motor into operation.
