ABSTRACT:
An arrangement for continuously compensating for unbalance of a rotary member such as a grinding wheel comprises an annular container which is adapted to be coaxially secured to the rotary member to be balanced. The container is subdivided in its circumferential direction into a plurality of balancing chambers which are accordingly disposed at different angular positions in relation to the rotary member. A compensating liquid can be introduced into the respective balancing chambers from the exterior thereof to provide an unbalance compensating effect. Associated with each of the balancing chambers is a respective chamber emptying valve which for the purpose of emptying compensating liquid from the respective chamber can be actuated by an actuating piston arranged coaxially with respect to the container and axially displaceable by a drive controlled from the exterior of the arrangement. The actuating piston actuates valve displacement elements which are radially displaceable for opening and closing the chamber emptying valves, by the axial displacement of the actuating piston.
