The GTM in-line planetary gearboxhas been designed for direct mounting to servo motors in high-precisionapplications. A wide range and modularconstruction make it possible to use the GTM in all factory automationapplications.

In the GTM in-line planetary gearbox, theservo motor is connected to the sun gearof the gearbox. This sun gear drives threeplanetary gears that rest in pinion cages.The planet gears revolve inside a ring gear,which is machined directly into the case ofthe gearbox, for unparalleled rigidity.

The GTMR right-angle hypoid gearboxhas been designed for highly-dynamicservo motors and allows for single-stagetransmission ratios of up to 15:1.For ratios greater than 15:1, a primary,planetary stage is added without increasingthe physical size of the gearbox.

Rexroth GTM and GTMR Benefits: Low noise: Cavities create noise, and our

internal cavity is smaller. The RexrothGTM and GTMR series are rated up to10dB lower than our closest competition.

Robust: Compared with other gearboxesof the same size, the Rexroth GTM andGTMR use the largest tapered rollerbearings possible. This allows for bothhigher radial and axial loads and givesthe bearings longer life.

Low operating temperatures: Thetapered roller bearings act as a pump,so that the minimum amount of oil canbe used in vertical, horizontal or angledapplications. This design allows theRexroth GTM and GTMR to generateless friction and less heat.

Safety and reliability: The cold-fusionprocess between the coupling anddriving gear allows high emergency- stop torque for maximum safety andreliability. The Rexroth GTM and GTMRspecify 1,000 emergency stops before lossof accuracy, compared with one time forcompetitive gearboxes.

Precision in motion

GTM and GTMR gearboxescan be fully integrated withRexroths complete line of

motors and drives.

Planetary and hypoid gearboxes from Rexroth have many innovative benefits for use ina broad variety of applications. Installed in environments from machine tools to printingmachines, these robust, compact systems provide precision in motion.

1. The robust output shaftensures the highest possibleaxial loads.

2. High radial force capability ismade possible through the useof large tapered roller bearings.

3. High accuracy is achievedthrough the use of highly-accurate, precision-groundgearing.

4. Robust Viton seals ensurepermanent IP65 integrity.

5. High torsional rigidity isachieved from an optimizedsun gear with stable supportfor the planetary gears at both ends.

6. Low-noise operations are theresult of optimized gear shapes.

7. Compact design isaccomplished by usingseparated drive bearings.

8. A special galvanic surfacetreatment makes the casingenvironmentally resistant.

9. Hermetically-sealed casing is accomplished by using capscrews rather than simpleplugs.

10. An integrated surface-treatedring-gear assists in thelubrication of the planetarygears.

11. High acceleration torquecapabilities are achieved byenforcing precision internalmachining tolerances.

12. Low gear temperatures andminimized losses are the resultof using the smallest possibleseal diameters.

13. The compression couplingensures backlash-free powertransmission.

14. A dual-stage version of theGTM in-line planetary gearboxis available for ratios greaterthan 10:1 (up to 100:1).

Diagram 1: Dynamic factor k1

For the peak torques caused by shortacceleration times with high cycle rates, the dynamic factor needs to be considered. For applications with fewer than 1,000 cycles per hour and for continuous duties, the dynamic factor k1 = 1.0.

Diagram 2: Frequency factor k2

There is a substantial influence of highoutput torques on the gearbox lifetime.The frequency factor takes intoaccount the duration percentage ofmaximum acceleration torque of thetotal cycle. For continuous duties, thefrequency factor k2 = 1.0.
