| 摘要 |
Embodiments of the present invention include strut based overrunning pulleys that provide one or more of greater durability, lower heat generation, high torque loads carrying capability, potentially tunable vibration dampening, tunable to maximum permissible torque loads before elastic (repeatable) slippage, and/or ease of end of life assessment. In some embodiments, a pulley assembly includes a shaft; a pocket plate having a plurality of pockets; a notch plate adjacent the pocket plate and having a plurality of notches facing the pockets of the pocket plate; a plurality struts disposed in the pockets; a resilient member disposed within the pockets and biasing the struts towards the notches; and a body disposed about the shaft, pocket plate, and notch plate; wherein one of the pocket plate or the notch plate is rotationally coupled to the shaft and the other of the pocket plate or the notch plate is rotationally coupled to the body.
