Warner Wrap Spring Clutches PSI

PSi series of mechanically actuated wrap spring clutches are simple devices providing high torque in a compact design. Specific models of this kind of clutches are start/coast-to-stop, start/stop – single revolution, and overrunning/one-way clutches.

Start/Coast – To-stop

The start/stop clutch is engaged until the collar that contains the spring tang is disengaged. Once it is stopped, the load is disengaged and coasts to a stop.

Start/Stop – Single Revolution

Attaching one end of the spring to the output hub results in a single-revolution clutch. The load is stopped through the spring to the collar. Precise non-cumulative error single-revolution cycling is achieved. Braking torque equals 10% of the maximum torque rating.

Overrunning/One-Way

This clutch continuously drives the load. The load can overrun the input should its speed exceed the input speed. In the reverse direction, the unit acts as a one-way clutch, preventing the load from backing up.
