TORQUE-PROPORTIONING DIFFERENTIAL WITH CYLINDRICAL SPACER ABSTRACT OF THE DISCLOSURE A gear differential is disclosed for supplying driving torque from an input shaft to a pair of aligned axially spaced output shafts, including a carrier housing driven by the input shaft and having a center section and a pair of end cover sections, a pair of side gears journalled in opposite ends of the center section for splined connection with the output shafts, respectively, and pairs of differential helical pinions having threads of opposite hands, respectively, the helical pinions of each pair being mounted with a running fit in longitudinal bores contained in opposite ends of the center section for threaded engagement with the side gears, respectively, the adjacent ends of the helical pinions being in overlapping enmeshing threaded engagement, characterized by the provision of a spacer cross pin member having a cylindrical shank portion extending transversely between, and for contiguous engagement by, the adjacent ends of the output shafts. The end cover sections of the housing are formed from pearlitic nodular iron, the adjacent ends of the cover sections being flame or induction hardened, whereby each section may be bolted by short bolts directly in contiguous engagement with the corresponding end of the center section, respectively.
