Title: Differential gear
Inventor: KAMIBAYASHI HIROKAZU
IPC: F16H48/38
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain proper clearances between housing holes and pinion gears after heat treatment by increasing an inner diameter of an opening side of the housing hole compared to that of a bottom side by a specified value before a differential bear case is heat-treated. SOLUTION: Before heat-treating a differential gear case 3 of a differential gear 1, opening sides of housing holes 29, 31 are machined to increase in diameter by contraction margins due to heat treatment from the bottom side. Proper clearances are thus obtained by heat treatment, from the opening to the bottom, between the housing holes 29, 31 and pinion gear 33, 35. Remarkable inclination of the pinion gear 33, 35 is thus prevented. It is thus possible to prevent occurrence of partial abrasion and pitching of the pinion gears 33, 35, housing holes 29, 31 and side gears 9, 11, and to remarkably improve durability. Differential limiting force of the pinion gear 33, 35 due to rotational resistance is kept properly by the proper clearances.
