Novel centrifugal self-lubricating tapered roller bearing retainer

Abstract

The invention discloses a novel centrifugal self-lubricating tapered roller bearing retainer and relates to the technical field of machinery foundation parts. The novel centrifugal self-lubricating tapered roller bearing retainer comprises a retainer body (1), an edge winding device (2), a window hole (3) and miniature grooves (4), wherein the edge winding device (2) is arranged at the opening position of the bottom part of the retainer body (1); the window hole (3) is formed in the middle part of the retainer body (1); the upper end and the lower end of the window hole (3) are respectively provided with the miniature groove (4). The novel centrifugal self-lubricating tapered roller bearing retainer disclosed by the invention has the advantages that the structure design is reasonable, and the use is convenient; oil is continuously supplied to a bearing by utilizing the mechanical property, so that the lubricating effect is guaranteed, not only is good lubricating condition provided, but also the quality of the bearing can be effectively controlled and the service life of the bearing is prolonged.

Description

Technical field: [0001] The invention relates to the technical field of mechanical foundation parts, in particular to a novel centrifugal self-lubricating tapered roller bearing retainer. Background technique: [0002] Bearings are precision mechanical basic parts. Due to the rapid development of science and technology, customers have higher and higher requirements on the quality of bearing products. Improving the bearing capacity of bearings and prolonging the service life of bearings have long become the needs of the development of industries such as automobiles. However, due to the limitation of the manufacturing process, the chronic problem of premature failure of bearings has been plagued by bearing manufacturers. Due to its own quality and external conditions, the bearing capacity, rotation accuracy and performance of rolling bearings will change during use. When the performance index of the bearing is lower than the use requirement and cannot work normally, it is ca...

AI Technical Summary

Problems solved by technology

Once the bearing is damaged or other accidents occur, there will be various abnormal phenomena such as stopping the machine and equipment and damaging the function, resulting in undue economic losses.

For heavy-duty axles, under normal use of tapered roller bearings (hereinafter referred to as bearings), the failure forms of the bearings are mainly: channel burns, fatigue failures and cage fractures. The main reason is that this type of bearings The load required to bear is relatively large, the ability to withstand compression is strong, and the lubrication conditions are required to be good. However, this type of bearing often cannot meet the use effect. Therefore, the quality of the bearing processing technology and material used for heavy-duty axles is strictly controlled. To improve bearing service life
