The torque limiter is a protective device that limits torque transmitted in a drive system by slipping when a preset value is exceeded as a result of shock load, overload or machine jam. It automatically re-engages when the overload is removed, no setting being required. Torque is transmitted by spring loaded friction faces, the value being preset by adjustment of the spring force by simple setting of the adjustment of the nuts and bolts.
It’s suitable to use with
- pulleys or
- a flange plate as the centre member clamped between the friction facings.
