Method of removing scratches and damages from the saddle shaped outer surface of the inner race for constant velocity axle joint of a car

Abstract

A novel system of removing scratches and damages from the saddle shaped outer surface of an inner race for a constant velocity axle joint of a car is comprised of an “O”-ring shaped sandpaper comprised of a flexible ring and an abrasive surface developed by adhering powders of abrasive materials such as aluminum oxide, ceramic aluminum oxide, aluminum zirconia, zirconia and silicon carbide to the outer surface of the flexible ring. The “O”-ring shaped surface of the sand paper of this invention fits the saddle shape of the outer surface of the inner race for constant velocity axle joint of a car. The sandpaper of this invention is mounted on a conventional belt sander equipped with three concave grooved belt wheels. The method of this invention enables even grinding and polishing of the saddle shaped outer surface of the inner race, which was impossible by the prior arts.

What is claimed is:  
     
         1 . A novel system of removing scratches and damages from the saddle shaped outer surface of an inner race for constant velocity axle joint of a car and a system, including an “O”-ring shaped sandpaper, being comprised of a flexible “O”-ring and an abrasive surface developed by adhering powders of abrasive materials applied to the outer surface of the flexible “O”-ring, and a band sander equipped with three concave grooved belt wheels.  
     
     
         2 . The abrasive material, in  claim 1 , is aluminum oxide.  
     
     
         3 . The abrasive material, in  claim 1 , is ceramic aluminum oxide.  
     
     
         4 . The abrasive material, in  claim 1 , is aluminum zirconia.  
     
     
         5 . The abrasive material, in  claim 1 , is zirconia.  
     
     
         6 . The abrasive material, in  claim 1 , is silicon carbide.
