Embodiment 1

[0028] Example 1, please refer to Figure 1~3 , a bearing cage that is easy to disassemble and assemble, including a cage body 3 that surrounds the balls 2 laterally, and a flying plate 4 that reaches the shaft frame 1 is integrally formed on the cage body 3, and the flying plate 4 is used as a plugging shaft frame 1 and The sealing setting between the balls 2 is used to prevent foreign matter such as dust from entering the balls 2 and affecting the normal rotation of the balls 2, thereby affecting the overall service life of the bearing. Considering the friction between the fly plate 4 and the axle frame 1, Therefore, it is recommended that the flying plate 4 be made of nitrile rubber, and be fixed with the metal cage body 3 by embossing. The cage body 3 is provided with an arc-shaped groove 5 at the position close to the ball 2 for contact with the ball 2. Close to each other to facilitate the rolling of the ball 2;

Embodiment 3

[0034] Embodiment three, please refer to Figure 1~2 and 5-6, a bearing cage that is easy to disassemble and assemble, including a cage body 3 that surrounds the balls 2 laterally, and a flying plate 4 that reaches the shaft frame 1 is integrally formed on the cage body 3, and the flying plate 4 is used as a plug The seal between the shaft frame 1 and the ball 2 is used to prevent foreign matter such as dust from entering the ball 2 and affecting the normal rotation of the ball 2, thereby affecting the overall service life of the bearing. Considering the fly plate 4 and the shaft frame 1 friction, so the flying plate 4 is recommended to be made of nitrile rubber, which is fixed with the metal cage body 3 by embossing. The cage body 3 is provided with an arc-shaped groove 5 at the position close to the ball 2. Because it is close to the ball 2, it is convenient for the ball 2 to roll;

Abstract

The invention discloses a bearing cage which is convenient to disassemble and assemble, which comprises a cage body which surrounds the balls in the transverse direction. The cage body is integrally formed with a flying plate which reaches the shaft frame. The cage body consists of a front frame body and a rear frame body located on the front and rear sides of the balls. The front frame body and the rear frame body between adjacent balls are fixedly connected by a limiting column, and the limiting column It includes an upper column welded and fixed on the rear frame and a lower column welded and fixed on the front frame. There are holes in the upper column, and a boss is welded on the top of the lower column, and the boss extends into the hole. , limit grooves are opened in the upper cylinder at the left and right sides of the hole, and steel balls are placed in the limit grooves. In the present invention, a flying plate made of rubber is integrated with the cage body, and the flying plate is used to seal the inner side of the ball to prevent dust from entering, which saves the trouble of installing the bearing oil seal in the later stage, and is integrally formed, and the processing is faster.

Description

technical field [0001] The invention belongs to the technical field of bearing equipment, in particular to a bearing cage which is convenient for disassembly and assembly. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The bearing cage (that is, the bearing cage, also known as the bearing cage) refers to partially wrapping all or part of the rolling body , and the bearing parts that move with it, to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing. [0003] When the bearing is working, especially when the load is complex and rotates at high speed, the cage has to bear a lot of centrifugal force, shock and vibration, there is a large sliding friction between the cage and the rolling elements, and a lot of heat is generated. The ...
