A torque limiter is an automatic device that protects mechanical equipment, or its work, from damage by mechanical overload. A torque limiter may limit the torque by slipping (as in a friction plate slip-clutch), or uncouple the load entirely (as in a shear pin). The action of a torque limiter is especially useful to limit any damage due to crash stops and jams.
Torque limiters may be packaged as a shaft coupling or as a hub for sprocket or sheave.
A torque limiting device is also known as an overload clutch.
Helical Inline gear units feature closely stepped speed reduction ratios, infinite life gears, high permissible radial forces and minimum backlash in a space saving design. A flexible modular design allows for a variety of input, output and mounting configurations.
