This clutch is designed to engage and disengage a motor from a shaft (not shown). The triangular lobes are attached to the outer ring through a living hinge. As the outer ring is driven by a belt, the lobes flex toward and lock onto the shaft. The idea behind it works, but unfortunately it doesn’t for my application. The shaft also translates and this clutch requires ‘grounding’. I use the term grounding to refer to the physical attachment of the inner ring, not an electrical characteristic.
