Embodiment Construction

[0018] Specific embodiments of the present invention such as Figure 1-3 As shown, a high-speed deep groove ball bearing cage includes a cage body 1 made of phenolic cotton laminated tube and a cage cover 2 made of aluminum material. The cage body 1 is provided with several pockets. holes 11 , the cage cover 2 is distributed on two sides corresponding to the axial direction of the cage body 1 , and the cage body 1 and the cage cover 2 are connected by rivets 3 . The phenolic cotton cloth laminated tube is a tubular laminated product made of cotton cloth impregnated with phenolic resin and baked by hot rolling. It has high radial tensile strength. The cage cover 2 is made of aluminum material, which can not only play a stable role Function, and the aluminum material is easily deformed to form a tight connection. The cage cover 2 and the cage body 1 form a three-layer sandwich structure, connected by rivets 3, the structure is simple, and the connection is convenient and stable....

Abstract

The invention relates to the technical field of bearings and particularly discloses a high-rotating-speed deep groove ball bearing retainer. The high-rotating-speed deep groove ball bearing retainer comprises a retainer body made of a phenolic aldehyde cotton cloth laminated pipe and retainer covers made of an aluminum material, wherein a plurality of pocket holes are formed in the retainer body, the retainer covers are distributed on the two corresponding sides of the axial direction of the retainer body, and the retainer body is connected with the retainer covers through rivets. By means of the above structure, the high-rotating-speed deep groove ball bearing retainer which is simple in structure, good in manufacturability, better in retainer dynamic balance, more suitable for high-rotating-speed working conditions, good in lubrication and long in service life is provided.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a high-speed deep groove ball bearing cage. Background technique [0002] The bearing cage is an important part of the rolling bearing, which separates and holds the rolling elements, and guides the rolling elements to roll on the predetermined track of the bearing ring. Generally, the cages of high-speed deep groove ball bearings are all nylon cages, but this kind of cage structure will be unbalanced when running under high-speed conditions. With the development of economy and society, high speed has become a trend of bearings, and the design of cage directly affects the high speed performance of deep groove ball bearings. Therefore, a new structural cage is urgently needed. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a high-speed deep groove ball bearing cage with simple structure, good manufactu...
