ABSTRACT:
A parallel-axis gear differential (10) includes a planetary gearing assembly of sun gears (22 and 24) and planet gears (26, 28, 30, 32, 34, and 36) carried within a housing (12). The planet gears (26, 28, 30, 32, 34, and 36), which are mounted in pairs within pockets (38, 40, 42, 44, 46, and 48) formed in the housing (12), include a first point of meshing engagement (74, 76) with one of the side gears (22, 24) and second and third points of meshing engagement (78 and 80) with a paired planet gear. A radial load component "Ws1" at the first point of engagement (74, 76) is adjusted with respect to a combined radial load component "Ws2" of the second and third points of engagement (78 and 80) for maintaining the planet gears (26, 28, 30, 32, 34, and 36) in their proper running positions within pockets (38, 40, 42, 44, 46, and 48).
