Description:
A Torque Limiter is also known as an
Overload Clutch. Its main function is to prevent damage to machine components and operations due to mechanical overloading. Mechanical overloading is common in several applications such as sudden crash stops and jams. When mechanical overloading is detected, the torque limiter reacts by limiting the torque either by slipping or completely uncoupling the load.
Torque limiters that work by uncoupling the load or drive are known as ‘disconnect type torque limiters’. This method prevents residual torque from reaching the load. This type of Torque Limiters includes Shear Pin, Ball Detent, Synchronous Magnetic, and Pawl and spring. These need to be reset after the load has
The second type of Torque Limiter is classified as ‘Limiting Types’. These devices use slipping to limit the machine’s torque. Slipping refers to letting the drive shaft move faster than the driven shaft and dissipating the excess power as heat. Examples of torque limiter applications that use slipping include Magnetic hysteresis, magnetic particle clutches and friction plates.
