Problems solved by technology

[0002] Inside the existing automotive differential, a spherical gasket is used between the planetary wheel and the differential case. As the planetary wheel rotates, grinding iron chips will be generated, which will increase the failure of the automotive differential and reduce the overall life of the differential.

Embodiment Construction

[0019] Accompanying drawing is a kind of specific embodiment of the present invention.

[0020] In the automotive differential and bearing combination structure of the present invention, a thrust bearing 6 is sandwiched between the differential case 3 and the top of the planetary gear 5, and the thrust bearing and the planetary gear are sleeved on the same shaft.

[0021] The contact surface between the thrust bearing and the differential case is a spherical surface 8 corresponding to each other, and the contact surface here on the thrust bearing is a static surface.

[0022] There are two pairs of planetary gears and a pair of side gears inside the differential case. The two pairs of planetary gears are arranged in a cross shape, located on the y-axis and the z-axis respectively. The shafts of the two pairs of planetary gears are cross-shaped shafts. The rotating shaft is located on the x-axis, and the half-shaft gear and its rotating shaft are fixed together to rotate synchr...

Abstract

The invention discloses an automobile differential mechanism and bearing combination structure. The combination structure is characterized in that a thrust bearing is clamped between a differential case and the top ends of planetary gears, and the thrust bearing and the planetary gears are arranged on a same shaft together in a sleeving mode. Contact surfaces of the thrust bearing and the differential case are spherical surfaces corresponding to each other, and the contact surface on the thrust bearing is a static surface. The combination structure has the beneficial effects that roller pin bearings rotate along with rolling of the planetary gears, grinding scrap iron is reduced, the internal lubrication environment is improved, the faults of the automobile differential mechanism are reduced, and the overall service life of the differential mechanism is prolonged.

Description

technical field [0001] The invention belongs to the field of bearings, and relates to an automobile differential gear and a combined structure of bearings. Background technique [0002] Inside the existing automotive differential, a spherical gasket is used between the planetary wheel and the differential case. As the planetary wheel rotates, grinding iron chips will be generated, which will increase the failure of the automotive differential and reduce the overall life of the differential. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides an automobile differential gear and bearing combined structure with simple structure and convenient use. [0004] The present invention is achieved through the following technical solutions: [0005] The automobile differential and bearing combination structure of the present invention is characterized in that: a thrust bearing is clamped between the differential...
