Power take-off unit having two-piece output gear assembly

摘要

A power take-off unit (40) includes a rigid housing (41) having an input gear (42) rotatably supported therein. An output gear assembly is rotatably supported within the housing. The output gear assembly (50) includes a toothed gear member (51a) and a bell member (52b) that are splined together. The toothed gear member (51a) meshes with the input gear (42) such that it and the bell member (52b) are rotatably driven thereby. The bell member is selectively connected through the clutch assembly (60) to an output shaft (54) that is rotatably supported on the power take-off housing (41). The output shaft (54) extends outwardly from the housing of the power take-off unit (41) and is adapted to be connected to a rotatably driven accessory. The two-piece structure of the output gear assembly (50) minimizes the cost and expense of manufacture and inventory and is more readily adaptable for varying the overall speed reduction gear ratio of the power take-off unit (40) as desired.
