12.3.18 Torque arms with slip-on gearboxes
12.3.18.1 General information regarding torque arms
Torque arms can absorb the reaction torque and the weight 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.
NOTICE
Damage to the rubber elements caused by solvent
Solvents, oils, greases, and fuels damage rubber elements.
Avoid contact at all times.
12.3.18.2 Mounting torque arms on parallel shaft gearboxes
We recommend using pretensioned, damping rubber elements.
Fixing accessories such as brackets, bolts, nuts, etc. are not included in the scope of supply.
