Bearing sleeve

Abstract

The invention discloses a bearing sleeve which comprises a sleeve body, wherein the sleeve body is internally provided with a first cone-shaped hole part, a second cylindrical hole part, a third cylindrical hole part and a fourth conical hole part, which are arranged in sequence from bottom to top; the outer wall surfaces, at the joint of the third hole part and the second hole part, of the sleeve body, are a concave circular surface and a convex circular surface which are connected; the outer wall of the lower part of the sleeve body is integrally connected with a mounting wall; four connecting holes are formed in the mounting wall; one side of the mounting wall outwards extends to form a connecting wall surface; the connecting wall surface comprises a second side wall and a third side wall which are directly connected with the mounting wall and a first side wall far away from the mounting wall; the first side wall is an inward concave curved surface; the second side wall and the third side wall are straight surfaces; circular connecting plates are respectively arranged on the connecting wall surface at the positions of boundaries of the first side wall, the second side wall and the third side wall; and a connecting hole is formed in the center of each circular connecting plate. The bearing sleeve has the advantages of being reasonable in structure, convenient to machine and manufacture, reliable to use, high in cost performance, and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile parts and appliances, and in particular relates to an automobile bearing sleeve. Background technique [0002] With the development of society, more and more cars have entered every family. Automobile bearings are a very important part of auto parts, but there are the following defects in the production and assembly process of auto bearings: (1) Many auto bearings will encounter difficulties in assembly and disassembly, especially in the bearings inside the box. The assembly is limited by conditions, and it is difficult to solve the problems of assembly and disassembly. (2) The bearing is arranged in the box body, so the processing precision of the box body is required to be very high, and the work efficiency of the box body processing is very low. (3) There will be axial movement of the bearing when it is in motion. The above defects make the assembly and production efficiency of th...

Problems solved by technology

Automobile bearings are a very important part of auto parts, but there are the following defects in the production and assembly process of auto bearings: (1) Many auto bearings will encounter difficulties in assembly and disassembly, especially in the bearings inside the box. Assembly is limited by conditions, it is difficult to solve the problem of assembly and disassembly

(2) The bearing is set in the box, so the processing accuracy of the box is very high, and the work efficiency of the box is very low.

The above defects make the assembly and production of the whole car inefficient and troublesome
