Embodiment Construction

[0011] like figure 1 It is a schematic diagram of the present invention, a special bearing cage, including a frame body 1, a pocket 2 and a boss 3, the pocket 2 is located in the frame body 1, the boss 3 is located on the two sides of the pocket 2, and the convex A support block 4 is arranged on the table 3 . The support block 4 is made of alumina ceramics.

[0012] When in use, the bearing is embedded in the pocket 2, so that the needle roller of the bearing is placed on the support block 4 on the boss 3. Since the support block 4 is made of alumina ceramic material, it not only provides a solid support for the needle roller of the bearing, It also has good wear resistance, which greatly improves the working stability and service life.

Abstract

The invention relates to the field of mechanical bearings and in particular relates to a special bearing cage. The special bearing cage comprises a cage body, pockets and bosses, wherein the pockets are formed in the cage body; the bosses are arranged on the two side edges of the pockets; support blocks are arranged on the bosses and are made of alumina ceramics. The special bearing cage has the beneficial effects that the support blocks made of the alumina ceramics not only provide a firm support for needle rollers of bearings but also have good wear resistance, thus greatly improving the working stability and prolonging the service life.

Description

technical field [0001] The invention relates to the field of mechanical bearings, in particular to a special bearing cage. Background technique [0002] Needle roller bearing is a kind of bearing that can withstand large radial force and is used in more compact situations. Generally, needle roller bearings use cages made of iron materials. The main disadvantage of this cage is noise during operation. large and prone to wear. [0003] SUMMARY OF THE INVENTION [0004] In order to overcome the shortcomings of the existing cages with high noise and easy wear, the present invention provides a special bearing cage. [0005] The technical solution adopted by the present invention to solve the technical problem is as follows: a special bearing cage, comprising a frame body, a pocket and a boss, the pocket is located in the frame body, the boss is located on two sides of the pocket, and the boss is located on the two sides of the pocket. There are brackets on it. [0006] The ...
