ABSTRACT:
A parallel-axis gear differential includes pairs of combination gears (66 and 68) mounted within pockets (76 and 78) formed in a differential housing (10, 12). Each combination gear includes a first gear section (70) for meshing with one of two side gears (58 or 60), a second gear section (72) for meshing with the first gear section of its mating combination gear, and a stem section (74) interconnecting the first two gear sections. Each pocket includes two bearing portions (84 and 86) for rotationally supporting the gear sections (70 and 72) and an intermediate portion (88) providing clearance for the stem sections (74). Windows (90) are formed through an exterior (92, 94) of the housing as passageways connecting the exterior of the housing to the intermediate portions (88). A spacing block (50) separates the side gears (58 and 60) through a distance approximately equal to an amount of overlap between the stem sections (74 ) of the combination gear pairs.
