Description: 
The Series 200 torque limiter is a state-of-the-art mechanical device that will disengage at a pre-set torque value. The trip torque is set above the normal start-up and operating torque, but below a torque setting which would normally damage the driving and/or driven equipment. In the event of a jam, the torque limiter eliminates the threat of damage by disconnecting the inertia in the drive train. In the normal drive condition, torque is transmitted through the drive balls (A) which are seated in detents in the drive plate (B) and the slide plate (C). These are all held together under pressure from spring (D). When the driven machine either jams or an overload occurs which is greater than the torque setting, the balls roll out of their seats and force apart the drive plate (B) and the slide plate (C). The balls are retained by the cage plate (E) and roll freely on the flat surface of the drive plate (B) and slide plate (C). Three types are available. They are Type AC - automatic rapid reset, Type ACT - automatic synchronous rest and Type AF - freewheeling, manual reset for high speed. Series 200 is offered in a large number of styles ensuring the right solution is available for all application such as timing, HTD and V-belt drives, chain and sprocket drives, gear drives, flexible or rigid couplings, flywheel or large gear mounting and special of unusual drive conditions.
