摘要

An automotive differential has two annular housing parts that are screwed together and an adjustment collar that is screwed into one of the annular housing parts. A ring gear is supported by bearings in the respective housing parts for rotation on a longitudinal axis that is perpendicular to a plane through the juncture of the two annular housing parts. A pinion gear is also rotatably mounted in the annular housing part that carries the adjustment collar for rotation on an axis that is not parallel to the longitudinal axis of the ring gear. The pinion gear meshes with the ring gear. Gear backlash and bearing preload are adjusted by indexing the two housing parts with respect to each other and by positioning the adjustment collar with respect to the one housing part.
