The basic wrap spring clutch and wrap spring brake consist of three elements: an input hub, an output hub, and a spring whose inside diameter is slightly smaller than the outside diameter of the two hubs. The torque capacity of a wrap spring clutch or wrap spring brake is a direct function of the diameter of the hub and the tensile strength of the spring.
- Wrap spring clutches or wrap spring brakes will not slip. It will attempt to supply the torque demanded, up to the mechanical limitations of the spring.
- The torque demand of the wrap spring clutch is equal to the system frictional torque of the load plus the dynamic torque of acceleration.
