Thrust ball bearing with dustproof and waterproof functions

Abstract

The invention discloses a thrust ball bearing with dustproof and waterproof functions. The thrust ball bearing comprises a seat ring, a shaft ring and rolling bodies; the middle of the seat ring is provided with a groove hole, the side, adjacent to the groove hole, of the seat ring is provided with a second sliding groove, the side of the seat ring is provided with a first rollaway groove, a baffle is installed on the side of the seat ring, and first sliding blocks are installed on the upper portion of the baffle at equal distance; the middle of the shaft ring is provided with an installing hole, an installing block is installed on the side, adjacent to the installing hole, of the shaft ring, a connecting plate is installed on the side of the installing block, second sliding blocks are installed on the side of the connecting plate at equal distance, and the side of the shaft ring is provided with a second rollway groove and a first sliding groove; and a retainer is movably clamped to the sides of the rolling bodies and located between the baffle and the connecting plate. According to the thrust ball bearing with the dustproof and waterproof functions, the dustproof and waterproof functions can be easily and conveniently achieved, and jamming of the rolling bodies is avoided; and meanwhile, radial loads of the side are effectively enhanced, and damage in the using process is avoided.

Description

technical field [0001] The invention relates to the technical field of thrust ball bearings, in particular to a thrust ball bearing with dustproof and waterproof functions. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. As a form of bearing, thrust ball bearings are getting more and more The wider the application. [0003] Thrust ball bearings are designed to withstand thrust loads during high-speed operation, and consist of a washer-shaped ferrule with raceway grooves for ball rolling. Since the ferrule is in the shape of a seat pad, thrust ball bearings are classified into flat base pad types. And self-aligning spherical cushion type two types. [0004] Push flow bearings are only suitable for parts that bear axial load on one side and have low speed, such as crane hooks, ver...

AI Technical Summary

Problems solved by technology

[0005] However, the existing thrust ball bearings have poor dustproof and waterproof performance, which makes it easy for dust and water to enter between the shaft ring and the seat ring during use, causing the internal rolling elements to be stuck and affecting The use of thrust ball bearings, on the other hand, during use, the performance of thrust ball bearings to withstand radial loads is poor, and in actual use, it is easy to cause damage, which is not conducive to use
