High-speed mute miniature precision bearing

Abstract

The invention discloses a high-speed mute miniature precision bearing which comprises a bearing outer ring and is further provided with a bearing retainer, a bearing rolling element, a bearing inner ring, a bearing outer protective coating and a bearing spacer bush mechanism, and the bearing spacer bush mechanism is composed of a spacer bush body, a mounting ring, an embedded block and a mounting square block. According to the high-speed mute miniature precision bearing disclosed by the invention, the miniature precision bearing can be conveniently mounted on a machine to be matched with transmission use of other parts through the arranged bearing outer ring, so that the miniature precision bearing is more excellent in use; the miniature precision bearing is more durable through the coatings in the arranged bearing outer protective coatings, sound generated by operation of the miniature precision bearing is reduced, the miniature precision bearing can be protected through the arranged bearing spacer bush mechanism, and therefore the outer surfaces of the two ends of the miniature precision bearing are prevented from being abraded, and the service life of the miniature precision bearing is prolonged. And a better application prospect is brought to the technical field of miniature precision bearings.

Description

technical field [0001] The invention relates to the technical field of miniature precision bearings, in particular to a high-speed and quiet miniature precision bearing. Background technique [0002] The original list of deep groove ball bearings is a radial ball bearing, which is the most widely used rolling bearing. It is characterized by small frictional resistance and high speed. It can also be used on parts that bear axial loads, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc. [0003] In the prior art, a Chinese patent document with the Chinese patent number CN202022430434.9 describes a deep groove ball bearing, in which the deep groove ball bearing is disclosed. The disadvantage is that the existing micro precision When the bearing is installed and used, two bearings need to be placed side by side.

Problems solved by technology

[0003] In the prior art, a Chinese patent document with the Chinese patent number CN202022430434.9 records a deep groove ball bearing, in which the deep groove ball bearing is disclosed, but the disadvantage is that the existing micro precision When the bearing is installed and used, two bearings need to be placed side by side. When using it, a spacer needs to be placed separately to prevent wear between the bearings, and the installed spacer will increase the noise when the bearing rotates, and the bearing will move in the bearing seat. possibility of

[0004] In view of the above shortcomings, it has brought certain adverse effects to people's use process. Therefore, we propose a high-speed and quiet miniature precision bearing to overcome the above problems.
