Abstract

A wrap spring clutch having a tri-lobe rotor 1 is shown in the drawing in place of the usual round shaft. As the clutch is energized, the wrap spring 2, which is anchored to the body 3 at 4, wraps down on to the lobes causing simple line contact. Slight distortion of the spring into the inter-lobe zones 5 causes a positive-locking action across the lobes. The tri-lobe concept provides a seif-cleaning action within the clutch.
