Parametric studies on modified configurations of ball-type passive balancers for improved transient and steadystate responses

A passive balancing device is a bearing with a set of masses that are free to move about a shaft axis of rotation. Beyond the first critical speed of the shaft, the masses assume positions that reduce vibrations due to imbalance. The conventional design of passive balancers is a dual-ball bearing. This type of balancer only performs its function at supercritical speeds and when the ball/track contact is nearly frictionless. In this work,...
