摘要： A differential apparatus (7) comprises: a differential casing (21) rotated by an engine power; a plurality of pinion gears (65, 66) slidably housed in accommodation holes (63, 64) formed in the differential casing: a pair of side gears (35, 37) geared with each other via the pinion gears, two opposing end surfaces thereof being slid relative to other either directly or via a thrust washer (61); and a block member (47, 91, 97) interposed between two inner circumferential surfaces of the two side gears so as to center the side gears, respectively. In particular, at least one oil sump (77, 79; 95; 101) is formed between the block member and the side gears, to supply lubricant to sliding portions between the block member (47, 91, 97) and the side gears (35, 37) and between two opposing end surfaces of the two side gears, by a centrifugal force generated by the rotating differential casing. Further, it is preferable to further form at least one central oil passage (301, 303, 305) at the centering portion (365) so as to extend from an inner circumferential side to an outer circumferential side of the boss portions (357, 359) of the two side gears (353, 355). Further, it is also preferable to form at least two radial oil passages (881, 885; 977, 978) between inner wall surfaces of the differential casing (821, 921) and the side gears (835, 837; 939, 941), respectively in such a way that a radially inward end thereof communicates with the helical oil passage (877, 879; 979L, 979R) and a radially outward end thereof communicates with sliding portion between the side gear and the differential casing, respectively.

摘要： A differential apparatus includes a differential casing, a pair of side gears and plural pairs of pinion gears. The pinion gears are accommodated in bores formed in the differential casing, respectively. On the side wall of the differential casing a plurality of lubrication holes are formed for introducing the lubrication oil into the differential casing. Each lubrication hole is arranged so that a center thereof is positioned in the vicinity of a meshing point of the pinion gears. In operation, due to the screw pumping effect of the pinion gears, plenty of lubrication oil is introduced into meshing portions of the pinion gears.

摘要： A differential apparatus includes a differential casing, a pair of side gears and plural pairs of pinion gears. The pinion gears are accommodated in bores formed in the differential casing, respectively. Each pinion gear has an outer diameter smaller than that of a standard gear to be determined corresponding to predetermined gear specifications. With such a forming of the pinion gears, the tip circular thickness of each pinion gear is increased, so that surface pressure at respective tips of the pinion gears is reduced to improve the seizure resistant capability.
