ABSTRACT:
A wrap spring clutch/brake apparatus includes a clutch mechanism for supplying increased frictional torque at low rotational speeds to a load. The clutch mechanism is formed of an inner cylindrical-shaped member, an outer annular member disposed concentrically around the inner cylindrical-shaped member, and a garter spring disposed concentrically around the outer annular member. The outer annular member is formed of a plurality of identical-shaped segmented fly-weights. Each segmented fly-weight has an inner arcuate section and an outer arcuate section disposed in a spaced apart relationship from the inner arcuate section by intermediate section. The inner arcuate section is disposed to be frictionally engaged with the outer circumference of the inner cylindrical-shaped member at lower rotational speeds to add increased frictional torque to the shaft output and is adapted for radial movement away from the frictional engagement with the inner member at relatively high rotational speeds.
