A manufacturing process of hinge bearing

Abstract

The invention discloses an innovative process for a hinge bearing. The bearing is composed of a driving plate-jacket compound body, a driving plate and steel balls. The driving plate-jacket compound body is a part formed by compounding a jacket and the driving plate. A driving shaft is mounted into the steel balls and the driving plate and then pivoted to the inner sides of open pores of the driving plate-jacket compound body. According to the innovative process for the hinge bearing, the low-cost production can be achieved, meanwhile, the long service life can be ensured, the surface appearance problem is solved, and the bearing capacity is improved manyfold and improved to the greatest extent. Accordingly, the great economic benefits are achieved, the great social benefits are achieved, and the economic benefits of users are ensured.

Description

technical field [0001] The invention relates to the technical field of hinge bearings, in particular to a manufacturing process of hinge bearings. Background technique [0002] The bearings currently used in the domestic and foreign markets are as shown in the attached figure 1 with 3 As shown; it is composed of a jacket, 2 dials and steel balls; because the jacket is formed by stamping process, the thickness of the material is very thin, resulting in defects such as easy deformation during use, unsightly appearance, and short service life. Its appearance is not beautiful because of the rounded corners formed by deep drawing, etc., and there is a large gap when sealing, the two sides are asymmetrical, and the size of the rounded corners is difficult to control; moreover, due to the thin material, the straight edge of the jacket is deformed when sealing; it is difficult to ensure The gap control required during the operation of the bearing is likely to cause wear during the...

Problems solved by technology

[0002] The bearings currently used in the domestic and foreign markets are as shown in the attached figure 1 and 3 As shown; it is composed of a jacket, 2 dials and steel balls; because the jacket is formed by stamping process, the thickness of the material is very thin, resulting in defects such as easy deformation during use, unsightly appearance, and short service life.

Its appearance is not beautiful because of the rounded corners formed by deep drawing, etc., and there is a large gap when sealing, the two sides are asymmetrical, and the size of the rounded corners is difficult to control; moreover, due to the thin material, the straight edge of the jacket is deformed when sealing; it is difficult to ensure The gap control required during the operation of the bearing is likely to cause wear during the operation, resulting in the imagination of the hinge wearing through the jacket after use, causing the bearing steel ball to fall, etc., thereby causing the bearing to fail.
