4.10 Torque arms with shaft-mounted gearboxes
Torque arms can absorb the reaction torque and the weight force of the gearbox.
NOTICE
Dangerous transient torques due to excess backlash
Take care to prevent the torque arm from causing excessive constraining forces, e.g. due
to the driven shaft running out-of-true.
NOTICE
Impermissible gearbox loading caused by incorrect mounting
Do not tension torque arms when mounting.
The torque arm bush must be supported by bearings on both sides.
