Planetary Gearbox

High operational reliability
High performance data
Easy attachment to machine
Risk of explosion! Fatal injuries, damage to the building and installation.
A motor-gearbox combination must comply with the explosion protection re‐
quirements according to the ATEX directive 94/5EC.
Servo planetary gearboxes according to ATEX for the attachment to MKE mo‐
tors are not offered or supplied by Rexroth, neither separately, nor mounted to
motors.
Renowned gearbox manufacturers have explosion-protected gear‐
boxes in their scope of delivery.
Please contact one of the following manufacturers recommended by Rexroth,

Planetary gearboxes of the GTS and GTP series are mechanically suitable for
the assembly on MKE motors.
They are particularly suited for use in S5 operation in gear racks or toothed
belts in handling systems with high speeds and accelerations (e.g.: loader, ro‐
bots).
Gearboxes of the GTS and GTP series are not certified according
to the directive 94/9/EC. For MKE motors with attached encoders,
Rexroth assumes no warranty or liability. The Ex protection verifi‐
cation certificate refers exclusively to the MKE motors. All further
mechanical add-on pieces are not considered and need an addi‐
tional inspection under the responsibilty of the machine or system
manufacturer.
● Low-maintenance operation owing to lifetime lubrication
● Use under adverse ambient conditions is possible (owing to the com‐
pletely closed design in IP 65 degree of protection)
● Low-play gear teeth with minimum reverse play owing to ground gear pairs
● High torsional strength owing to load distribution to three planetary wheels
● High efficiency owing to planetary wheel principle
● High dynamic because of inertia
● Low weight due to compact design
● Direct overhung mounting of gear pinions and belt pulleys, owing to the
bearing being designed for high permissible radial loads
