Dynamic balancing - device for balancing of rotating machine parts, in particular grinding wheels

摘要

A device for balancing rotating bodies such as grinding wheels, by causing the center of gravity of a counterweight to move along a predetermined path relative to the body while the latter is rotating. The path followed by the center of gravity of the counterweight is such that it is caused to continually and repeatedly increase and decrease its radial distance from the axis of rotation as it progresses angularly around the axis. Preferably, provision is made for reversing its direction of movement along the path so that balance may be approached by the shortest route.
