PLANETARY GEAR CARRIER JOINT FOR PRECISION RE-ASSEMNBLY AND TORQUE TRANSMISSION

摘要

A planetary gear carrier has a drum cover and drum hub that make up a drum of the carrier and a carrier plate spaced from the drum cover defining a space in which the planetary gears reside. The drum cover, drum hub and carrier plate are joined by keys that are formed integrally with at least one of them that mate with surfaces of the other parts for precise assembly and re-assembly, and windows are defined through sets of spline teeth of the dram cover and drum hub through which planetary gears may be inserted for assembly to the carrier while the drum cover, drum hub and carrier plate are assembled to one another.
