1 Introduction to the Product
1.1 GTE Planetary Gearboxes
Fig.1-1: Mounting example: GTE planetary gearboxes mounted on IndraDyn S
motors
Application area In combination with the drive and control system of Rexroth, GTE planetary
gearboxes provide a low-cost automation system for various sectors of indus‐
try.
They are well-suited for use with gear racks or toothed belts in handling sys‐
tems with high speed and accelerations (e.g.: loader and robots).
The low-backlash with shave-grinded (honed) planet wheels permits the exe‐
cution of exact positioning tasks. Furthermore, the gearboxes are suited for
S1-operation-required for application in e.g. the printing sector.

Mode of functioning The GTE series of planetary gearboxes offers a coaxial input and output. The
output shaft of the motor is connected to the sun gear with a non-positive
compression clamp coupling. This sun gear drives three planetary wheels,
which roll off on an internal gear with internal gear teeth, as a single-stage
gearbox and four planetary wheels as a two-stage gearbox. The planetary
gears are fixed in the planet carrier, which acts as the output. By dividing the
load among the planetary gear on three or four planetary wheels, a balanced
force splitting occurs. This allows for a very compact gearbox with a high
power density.
High operational reliability ● Maintenance-free operation through lifetime lubrication
● Use under adverse environmental conditions is possible due to the com‐
pletely enclosed IP54 design.
● Safe and lasting sealing by abradant bearing sealants.
● Hermetically sealed housing
● Non-positive from backlash-free torque transmission via the compres‐
sion coupling
High performance data ● High accuracy via shave grinded (honed) planetary wheels, low back‐
lash gearing with low torque play.
● High efficiency, low temperature and minimum power loss made possi‐
ble by using the smallest possible seal diameters.
● Low running noise by optimized gear profiles.
● High emergency stop torque made possible by internal transferred pow‐
er.
● Highly dynamic because of inertia
● Low weight through compact type of construction
Easy to mount to machine ● The high radial-load capability and tilt resistance makes it possible to di‐
rectly mount a pinion or pulley.

Introduction to the Product
● The design of the output shaft with a solid shaft shoulder makes axial
tightening of output elements simple.
● The gearbox can be mounted in any position. Due to the defined bear‐
ing position and pump current a sufficient lubricant supply is always en‐
sured.
● The output elements can be mounted in two different ways:
– non-positive shaft-hub connection by means of a plain output hol‐
low shaft, or
– connection by means of an output shaft with keyway
