4.11 Torque Restraint

The VLT® OneGearDrive® requires a suitable torque restraint to resist the reaction torque. The torque arm with mounting set is avail-
able as an option (see 9.7.1 Torque Arm
due to the driven shaft running untrue. Excessive backlash can result in excessive shock torques in switching or reversing opera-
tions.
