TORSIONAL VIBRATION ABSORPTION SYSTEM

摘要

A system for absorbing vibration and transmitting torque from a rotating power source to a rotatable load includes a rotatable driving member configured as an input to be driven by the power source to rotate about an axis of rotation. The system has a cam plate with a cam surface. A spring is configured to extend lengthwise in a radial direction relative to the axis of rotation. The spring is configured to be compressed due to the cam surface during relative rotation of the driving member and a driven member when the cam plate is operatively connected to rotate in unison with said one of the driving member and the driven member. The spring therefore has an effective spring rate dependent upon the cam surface, compression of the spring absorbs torsional vibration of the driving member, and the cam plate.

1. A system for absorbing vibration and transmitting torque from a rotating power source to a rotatable load, the system comprising:
a cam plate having a cam surface and configured to be rotatable about an axis of rotation with one of the power source and the load; a spring configured to extend lengthwise at least partially in a radial direction relative to the axis of rotation and rotatable with the other of the power source and the load; and wherein the spring is configured to be compressed due to the cam surface during relative rotation of the power source and the load, the spring therefore having an effective spring rate dependent upon the cam surface, compression of the spring absorbing torsional vibration of the power source.
