Mechanical Torque Limiters

Product Type: Torque Limiters

Mechanical torque limiters are single or multi-position, ball/detent interface torque overload devices. They protect drive and driven components from damage associated with torque overloads.

Backlash free torque transmission is accomplished with a series of balls nested in hardened detents in the units interface. Possible torque ranges from 40-24,000 in-lbs. Overloads are detected with a proximity sensor that signals the drive to shut down. High-speed applications use a full disengagement model that free wheels when an overload occurs.

Re-engagement is done manually by jogging into position. See more at Design World Motion Control Tips Protecting Against Mechanical Overload Damage
