Convenient-to-disassemble and assemble noiseless dust prevention device for thrust ball bearing

Abstract

The invention provides a convenient-to-disassemble and assemble noiseless dust prevention device for a thrust ball bearing. The dust prevention device comprises a seat ring, an annular soft brush layer B and a spherical embedded block, wherein a plastic dust prevention protective ring A is connected to the peripheral surface of the seat ring in a sleeving manner; the inner diameter of the plasticdust prevention protective ring A is consistent with the outer diameter of the seat ring; and a plastic dust prevention protective ring B is connected to the peripheral surface of a holder positionedbetween the seat ring and a shaft ring in a sleeving manner. According to the convenient-to-disassemble and assemble noiseless dust prevention device, during mounting, one plastic dust prevention protective ring A is connected to the peripheral surface of the shaft ring in a sleeving manner, one plastic dust prevention protective ring A is connected to the peripheral surface of the seat ring in asleeving manner, the plastic dust prevention protective ring B is connected to the peripheral surface of the holder in a sleeving manner, annular soft brush layers A are arranged in an annular limiting dust prevention block structure and an annular limiting dust prevention groove, external dust can be effectively prevented from entering the thrust ball bearing during daily utilization, and utilization quality of the thrust ball bearing is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of thrust ball bearings, and more specifically relates to a dust-proof device for thrust ball bearings that is easy to disassemble and has no noise. Background technique [0002] Thrust ball bearings are designed to withstand thrust loads during high-speed operation, and consist of washer-shaped rings with raceway grooves for ball rolling. [0003] Thrust ball bearings are generally suitable for parts that bear axial load on one side and low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc., but are often easily affected by dust entering The service life of the bearing. Therefore, it is necessary to provide a dust-proof thrust ball bearing structure. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a dust-proof device for thrust ball bearings that is easy to disassemble and has no noise,...
