Maximum Transferable Output Torque
At M
out, nenn
, Bosch Rexroth`s planetary gearboxes are designed for high-
cycle operation, in other words, if the application torques are always less than
the nominal torque, no recalculation is necessary. However, it is possible to
transfer higher application torques in the case of short torque peaks or long
periods of intermittent duty. The following figure serves as guideline:

Increase facture depending on the number of rotations of the output
shaft
The maximum application torque must not exceed 1.6 x M
out, nenn
. The num‐
ber of rotations of the output shaft at the max. torque has to be calculated. If
the number of rotations is larger than 15.000.000, the gearbox may only be
subjected to the nominal torque of the gearbox. If the number of rotations is
smaller than 15.000.000, the increase factor can be calculated by means of
the following formula:
If f > 1.6, f is set to 1.6
If f > 1.0, f is set to 1.0
The maximum transferable moment M
out, max
of the gearbox is then calculated
by means of M

= f · M

.
the maximum application torque must not exceed the calculated maximum
output torque of the gearbox.
