ELASTOMERIC SPRING PULLEY ASSEMBLY FOR ROTARY DEVICES

摘要

A pulley assembly for a rotary device such as an automotive alternator comprising a pulley, a hub, and one or more elastomeric springs to cushion and attenuate the effect of sudden rotational velocity variations of the pulley and the hub. Premature spring failure is prevented by a mechanical stop arrangement that limits the amount of relative rotation between the pulley and hub to prevent over-compression of the springs.
