Fig. 1-1: Mounting example: GTM Planetary gearbox on an MKD motor
In combination with the drive and control systems of BOSCH REXROTH,
GTM planetary gearboxes, provide a low-cost automation system for
various sectors of industry.
They are well-suited for use with gear racks or toothed belts in handling
systems with high speed and accelerations (e.g.: loaders, robots).
The low-backlash, ground and matched gearing permits the execution of
exact positioning tasks. Furthermore, the gearboxes are suited for S1-
operation-required for use in printing sector.

1-2 Introduction to the Product Planetary Gearboxes
DOK-GEAR**-GTM********-PR01-EN-P
The GTM series of planetary gearboxes offers a coaxial input and output.
The output shaft of the motor is connected to the sun gear with a
compression clamp coupling. This sun gear drives the planetary gears,
which revolve within the ring gear. The planetary gears are fixed in the
planetary carrier, which acts as the output. By dividing the load among the
planetary gears, a balanced force splitting occurs. This allows for a very
compact gearbox with a high power density.
•Maintenance-free operation through lifetime lubrication
•Use under adverse environmental conditions is possible thanks to the
completely enclosed IP65 design.
•Viton seals on the input and output provide safe and effective
protection.
•Hermetically sealed housing
•Power transfer free from backlash-free torque transmission via the
compression coupling.
•High accuracy through use of ground, gears and low backlash.
•High torsional rigidity by optimized planetary gears supported on both
sides with stabile needle bearings.
•High efficiency, low temperature and minimum power loss made
possible by using the smallest possible seal diameters.
•Low running noise by optimized gear profiles.
•High emergency stop torque made possible by internal transferred
power.
•High dynamic because of low inertia
•Low weight through to compact design
•The high radial-load capability and tilt resistance makes it possible to
directly mount a pinion or pulley.
•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 bearing design
and its pumping action, a sufficient lubrication supply is always
ensured.
•Flange mounting is permitted in all installation positions because of the
B05 design (EN 60034-7:1996-06).
•The output elements can be mounted in two different ways:
•Compression fitting on the smooth shaft (standard), or
•Connection by means of an output shaft with keyway
Mode of functioning
High operational reliability
High power
Easy to mount to machine
