Abstract
An isolator comprising a hub, a pulley frictionally engaged with the hub through a bushing for instantaneous rotational movement, the bushing and hub having a coefficient of friction, a resilient member engaged between the pulley and the hub for transmitting a torque, and a locking member for retaining the pulley on the hub.
Claims
exact text as granted — not AI-modified1 . An isolator comprising:
a hub; a pulley frictionally engaged with the hub through a bushing for instantaneous rotational movement, the bushing and hub having a coefficient of friction; a resilient member comprising a torsional spring engaged between the pulley and the hub for transmitting a torque; a first cam member having a first cam surface, the first cam member fixed to the pulley; a second cam member having a second cam surface slidingly engaged with the first cam surface; the first cam member and the second cam member pressingly engaged between the resilient member and the hub; and a locking member for retaining the pulley on the hub.
2 . The isolator as in claim 1 further comprising a roller bearing disposed between the first cam surface and the second cam surface.
3 . The isolator as in claim 1 further comprising a damping member disposed between the pulley and the hub for damping a pulley oscillation.Join the waitlist — get patent alerts
