Document Type and Number:
Japanese Patent JP2023114856
Kind Code:
A
Abstract:
To provide a differential arrangement which inhibits complication of a cast while enabling an oil hole for supplying a lubrication oil to the interior of a differential case to be formed by casting to improve mass productivity.SOLUTION: A differential arrangement 1 includes: a differential case 2 integrally having a cylindrical part 21 and a bottom part 23; a first side gear 31 and a second side gear 32 disposed within the differential case 2; and a pinion gear set 4 formed by causing a first pinion gear 41 which engages with the first side gear 31 and a second pinion gear 42 which engages with the second side gear 32 to engage with each other. In the differential case 2, an oil hole 20 for introducing a lubrication oil is formed extending in an axial direction. One axial end 201 of the oil hole 20 is formed at the cylindrical part 21 and the other axial end 202 of the oil hole 20 is open on an outer surface 23a of the bottom part 23. A width W of the oil hole 20 in a circumferential direction of the cylindrical part 21 is formed so as not to narrow from the one end 201 to the other end 202.SELECTED DRAWING: Figure 2
