Novel bearing without traditional retainer structure

Abstract

The invention relates to a bearing technology in the field of mechanical engineering, in particular to a short cylinder with a novel structure and a radial ball bearing. Compared with a traditional bearing, four parts are optimized into three parts, and the bearing has the advantages of being easy to machine (including ultra-large type), low in cost, long in service life and low in operation noise.

Description

TECHNICAL FIELD

[0001] Industrial production, mechanical manufacturing, transportation BACKGROUND

[0002] Traditional bearings use retainers as important structures to support the inner and outer sleeves and rollers of the bearings, but also increase friction, reduce bearing life and precision, generate loud operating noise, complicate the processing technology, and increase the cost SUMMARY

[0003] The present application relates to the technical field of bearings in mechanical engineering, in particular to a new type of bearing with improved load bearing capacity, reduced friction coefficient, and prolonged service life. The manufacturing process of the bearing is greatly simplified, and various large, medium, and small specifications of short cylindrical and radial ball bearings can be produced.

[0004] The present application is particularly suitable for the bearing structure of high-speed rotating equipment, which can withstand high loads while generating less heat and reducing maintenance requirements, thereby minimizing product friction and prolonging service life.

[0005] Traditional bearing designs rely heavily on retainers to evenly distribute the rollers and generate friction with the rollers. Therefore, the retainers bear a large amount of friction in the bearing, making them vulnerable components that affect the service life of the bearing. In practical engineering applications, the retainers generate a large amount of heat, which poses a significant challenge to the overall system in terms of heat dissipation and continuous stable operation. In addition, the continuous friction also causes wear and tear of the retainers and rollers, generating friction debris, which reduces the precision and service life of the bearing.

[0006] The present application eliminates the retainers and cleverly uses the arrangement of the rollers to convert the reaction force in traditional bearing designs into an acting force. The present application has the advantages of high precision, simple production process, low cost, and low heat generation.

[0007] The rollers in the bearing of the present application are arranged in groups of four, and the diamond-shaped stacking layout is used to ensure stability. Adjacent diamonds share a roller (i.e., triangular stacking), and the rollers are arranged in multiple groups. The diameter of the rollers can be adjusted as needed.
