METHOD FOR PRODUCING AN ASSEMBLY BY FRICTION WELDING

摘要

Cluster gear assemblies are produced by a method and apparatus which join a plurality of pre-machined gears by a common joining member. The plurality of gears are held in relative nonrotative relationship by special holding means which further establish precise angular and axial alignment between the gears and axial alignment between the joining member and the gears. Joining of the various members to produce the assembly is accomplished by friction welding.
