LUBRICATING STRUCTURE FOR DIFFERENTIAL DEVICE

摘要

PROBLEM TO BE SOLVED: To enable more lubricating oil scattered from a bearing to be led to a lead-in hole. SOLUTION: The lead-in hole 19 opposing to a bearing 34 in an axial direction and establishing communication between an inside and an outside of the center case 3 is formed on the center case 3. A case side annular part 83 projecting in a rotary shaft axial direction at a rotation radius direction outside of the center case 3 more than the lead-in hole 19 is provided on the center case 3. A stationary side annular part 85 projecting in an axial direction at a radially outside more than the bearing 34 is formed on a support part 32 of a bell housing 8. An oil pocket 81 is formed between the center case 3 and the support part 32 of the bearing 34 and the bell housing 8. The case side annular part 83 and the stationary side annular part 85 overlap in the rotation radius direction by dimension a. COPYRIGHT: (C)2008,JPO&INPIT
