Abstract
A parallel-axis gear differential has pairs of top and bottom planet gears (38 and 40, 42 and 44, and 46 and 48) operatively connecting a pair of side gears (30 and 32). Each of the planet gears has a main gear section (74, 80) and a transfer gear section (76, 82) interconnected by a stem section (78, 84). Teeth (86 and 88) of the side gears (30 and 32) are separated through a clearance space (100) formed by a hub (98) of side gear (32). Within the clearance space (100), teeth (90 and 94) of the main planet gear sections (74 and 80) overlap the side gear teeth (86 and 88). Inner and outer ends (102 and 104) of the side gear teeth (86 and 88) are inclined at a chamfer angle (A) throughout a distance that extends between top and bottom lands (106 and 108) of the side gears.
