Abstract
A planetary transmission assembly including a composite planetary staking pin is disclosed. The composite planetary staking pin fixes a planetary gear to a planetary carrier, and the planetary gear is supported on the composite planetary staking pin by rolling elements. The composite planetary staking pin includes an inner pin body having axial ends with circular grooves. The composite planetary staking pin is fixed to the planetary carrier via staking of the axial ends of the inner pin body. An outer sleeve of the composite planetary staking pin is fixed to the inner pin body. The outer sleeve defines a circumferentially extending helical channel that provides a lubricant flow path between an inlet defined by the planetary carrier and an outlet to the rolling elements.
