METHOD FOR ADJUSTING AN AXIAL BIASING FORCE OF A SHAFT IN A TRANSMISSION

摘要

A method for adjusting an axial biasing force of a shaft in a transmission is described that involves manufacturing a variety of shims of different lengths by bending wires into rings that are not closed along their circumference. Shims are selected from the variety of shims of different lengths dependent and inserted between the first tapered roller bearing and a housing wall of the transmission for adjusting a manufacturing biasing force. By heating the assembled transmission to an operating temperature, the biasing force is decreased below the manufacturing biasing force or becomes zero. This accomplishes a minimal friction and therefore a smooth synchronization while still avoiding play during operation.
