Grinding machine for rolling bearing rings - has ring resting on three support rollers and driven by locating rollers at periphery

摘要

The machine is distinguished by the method of clamping the ring for grinding. The ring (1) rests on three support rollers (3) which are mounted on slides (2) spaced 120 deg. apart. One slide is fixed and the other two can be radially adjusted to accept different sizes of ring. The fixed slide has a pair of rollers (4) which bear against the outside surface of the ring and locate it. The adjustable slides have rollers (5) which bear against the outside surface of the ring, one being driven to rotate the ring during grinding. The clamping forces are low, and the location of the ring against the rollers is facilitated by slightly inclining the roller axes. ADVANTAGE - Automatic workpiece loading is simplified. Quickly and easily adjustable for different sizes of work. Effect of clamping forces on accuracy is reduced.
