Problems solved by technology

[0004] 2. The rolling ball is small in size, and it is not easy to operate when picking it up with tweezers;
[0005] 3. The rolling ball is light in weight, especially the miniature ceramic ball. The airflow exhaled by the assembler can blow away the ceramic ball. Therefore, it is very easy to lose the rolling ball during assembly
[0006] 4. In order to fix the ball in the pocket of the cage, Vaseline is mostly used to adhere the ball during assembly at present, and it is cleaned after assembly. Because Vaseline is difficult to clean after assembly of miniature bearings, Vaseline impurities will affect the bearing. Assembly and use precision

Embodiment Construction

[0020] The present invention is a simple assembly method of a miniature ball bearing. The bearing assembled with the inner diameter of the inner ring not greater than 10 mm and the diameter 2r of the rolling ball not greater than 1.588 mm is called a miniature ball bearing, where r is the radius of the rolling ball , the assembly quantity of rolling balls matches the setting quantity of cage pockets, and the lubricating oil required for rolling balls in cage pockets has been given.

[0021] In order to clearly introduce the present invention, the outer ring 1, the cage 3 and the inner ring 4 in the miniature ball bearing are customized as follows, and these customizations will not be further explained in the following description.

[0022] Set the inner diameter reference of outer ring 1.

[0023] combine image 3 , The width of the cage 3 is represented by HC, the wall thickness of the cage 3 is represented by HB, and the outer diameter of the cage 3 is represented by d1.

Abstract

Disclosed is a simple assembly method for miniature ball bearings. Firstly, a ball holding ring (5) and a support (6) are manufactured, the support is placed in a positioning ring (5.2) of the ball holding ring, and a cage (3) soaked with lubricant is placed at the bottom of an inner ring of the support. Secondly, an inner ring (4) is mounted in the cage, the inner ring contacts with the bottom of the inner ring of the support, rolling balls (2) soaked with lubricant and having equal amount to that of arranged cage pockets are placed on an assembly support surface, and one of the rolling balls is toggled slightly by a small scoop so that the rolling ball enters one pocket of the cage until all the rolling balls enter the cage pockets. Thirdly, one slope end of an outer ring (1) is aligned with the cage and is pressed down to fully contact with an outer ring, with the height of H, of the positioning rings on the ball holding ring. Finally, the ball holding ring and the support are removed after a miniature ball bearing not assembled, the ball holding ring and the support are turned over, the outer ring continues to be pressed to be parallel to the inner ring, and accordingly simple assembly of the miniature ball bearing is achieved.

Description

technical field [0001] The invention belongs to the technical field of bearing assembly, in particular to a simple assembly method of miniature ball bearings. Background technique [0002] For miniature bearings, since the inner diameter of the inner ring is not greater than 10 mm, the diameter of the ball is generally below 1.588 mm, the smallest ball is about 0.3 mm, and the weight of the ball is 0.00011 to 0.0163 grams. If it is a ceramic ball, the weight is more Small, only about 40% of the weight of a rolling ball of the same size. Due to the small size and light weight of the balls or ceramic balls used in miniature ball bearings, it is extremely difficult to assemble them. The main difficulties are as follows: [0003] 1. The pocket of the cage is small, and the rolling ball is not easy to be sent into the pocket; [0004] 2. The rolling ball is small in size, and it is not easy to operate when picking it up with tweezers; [0005] 3. The rolling balls are light in...
