Spring Clutches for Rotary Motion Control...-Image

Tiny Clutch/Helander Products, Inc. specializes in the design and manufacture of miniature clutches to serve a broad range of rotary motion control situations. Talk to us about Overrunning Spring Clutch, On-Off Spring Clutch, Indexing Spring Clutch, Adjustable Indexing Spring Clutch, Positive Stop Indexing Spring Clutch.

The basic wrap spring clutch consists of three parts: an input hub, an output hub, and a spring. The inside diameter of the spring is slightly smaller than the outside diameter of the two hubs. When the parts are assembled and one hub is rotated in the direction that the spring is wound, the spring wraps down tightly on both hubs causing the clutch to drive. The greater the force the tighter the spring grips the hubs. When the rotation is reversed, the spring loosens its grip and slips. In the free direction there is slight drag caused by the spring being slightly smaller than the drums. This friction can be used to create a non adjustable torque limiter as well.
