4.6 Gearboxes in foot or flange version
NOTICE
Impermissible housing loadings caused by incorrectly installed add-on elements
Do not subject the gearbox housing to excessive stress by adding add-on elements to the
foot or flange.
Add-on elements must not transmit forces, torques, and vibrations to the gearbox.
To prevent strains on the housing, fasten the gearbox only on the flange or the foot fastening
for force and torque transmission. Refer to Gearbox with foot mounting (Page 32).
The second mounting option (foot or flange) is intended for add-on elements, e.g. protection
covers with an intrinsic weight of up to max. 30 % of the weight of the gearbox.
