ABSTRACT:
A wear distributing arrangement for reduction of wear in parts of a grinding machine is disclosed. The arrangement includes the provision of multiple corresponding projections and recesses at evenly spaced radial locations around the circumference of any two parts in a rotating assembly designed to be disassembled and reassembled. Parts bearing projections are reassembled into parts bearing recesses in a random fashion, so that wear to one portion of a part does not prematurely wear it.
