A SSPTP torque limiter is an Friction based automatic equipment that protects mechanical equipment, or its work, from damage by mechanical overload . Torque Limiting Couplings, specifically, work by slipping during torque overload to prevent driven components from experiencing excessive torque loads.
It works on friction theory, which provides jerk free disengaging and engagement of the drive.
A torque limiting coupling limit the torque by slipping on friction disc. It may also uncouple the load completely.
A torque limiter is especially useful when you want to limit any damage due to crash stops and jams. If a torque overload occurs, the Torque Limiter is able to protect critical equipment by disconnecting the driving shaft from the driven components.
