Abstract

Official abstract text for this publication.

A device for producing a curved lateral surface on a rolling element for a rolling bearing includes a grinding apparatus for grinding the curved lateral surface and a retaining apparatus having a control wheel with a convexly profiled peripheral feeding surface for retaining the rolling element during the grinding. The retaining apparatus may include a plurality of control wheels. The control wheel or the convexly profiled peripheral feeding surface may be formed from a ceramic, a resin-bonded synthetic, or a metallic material. The device may include a dressing apparatus for profiling the convexly profiled peripheral feeding surface of the control wheel.

First claim

Opening claim text (preview).

The invention claimed is: 1. A device for producing a curved lateral surface on a rolling element for a rolling bearing, comprising: a grinding apparatus for grinding the curved lateral surface; a retaining apparatus comprising a control wheel with a convexly profiled peripheral feeding surface for retaining the rolling element during the grinding; and a dressing apparatus for profiling the convexly profiled peripheral feeding surface of the control wheel. 2. The device of claim 1 wherein the retaining apparatus comprises a plurality of control wheels. 3. The device of claim 1 , wherein the control wheel or the convexly profiled peripheral feeding surface is formed from a ceramic, a resin-bonded synthetic, or a metallic material. 4. The device of claim 1 , wherein the dressing apparatus is arranged to convexly profile the convexly profiled peripheral feeding surface. 5. The device of claim 1 further comprising a control apparatus for controlling the dressing apparatus. 6. The device of claim 1 , wherein the grinding apparatus is a grinding wheel with a concavely profiled peripheral grinding surface. 7. A device for producing a curved lateral surface on a rolling element for a rolling bearing, comprising: a grinding wheel with a concavely profiled peripheral grinding surface for grinding the curved lateral surface; a retaining apparatus comprising a control wheel with a convexly profiled peripheral feeding surface for retaining the rolling element during the grinding; and a dressing apparatus for: sharpening or calibrating the concavely profiled peripheral grinding surface; profiling the concavely profiled peripheral grinding surface; or profiling the convexly profiled peripheral feeding surface. 8. The device of claim 7 , wherein the dressing apparatus is arranged to: concavely profile the concavely profiled peripheral grinding surface; or convexly profile the convexly profiled peripheral feeding surface. 9. The device of claim 7 further comprising a control apparatus for controlling the dressing apparatus. 10. A method for producing a curved lateral surface on a rolling element for a rolling bearing comprising: providing the device of claim 1 ; arranging the rolling element on the convexly profiled peripheral feeding surface; grinding the curved lateral surface; and processing or convexly profiling the convexly profiled peripheral feeding surface with the dressing apparatus. 11. The method of claim 10 , further comprising: providing a control apparatus; and controlling the dressing apparatus with the control apparatus to convexly profile the convexly profiled peripheral feeding surface. 12. The method of claim 10 , wherein the processing or convexly profiling the convexly profiled peripheral feeding surface with the dressing apparatus comprises wire electrical discharge machining.
