Improved thrust ball bearing suitable for heavy-load low-speed working condition

Abstract

The invention provides an improved thrust ball bearing suitable for a heavy-load and low-speed working condition, relates to the technical field of bearings, and aims to solve the problems that when an existing thrust ball bearing is used, impurities on bearing balls need to be removed through disassembly, and time and labor are wasted. The improved thrust ball bearing comprises a main body, a connecting piece, a cleaning piece and a smearing piece, and an arc-shaped groove is formed in the top of the main body; the connecting piece is mounted at the top of the main body; a sliding groove in the connecting piece is formed in the top of the main body, and a top groove in the connecting piece is formed in the edge position of a top plate; the cleaning piece is mounted in the main body and the top plate, and an inner groove in the cleaning piece is formed in the top of the main body and the bottom of the top plate; and the smearing piece is installed on the top of the top plate, and a flow guide groove in the smearing piece is formed in the top of an inner plate. The arc-shaped structures at the outer ends of scrapers are attached to balls installed in the inner plates, impurities generated when the scrapers clean the balls are discharged through gaps between the inner plates, and the steps of bearing disassembly and re-cleaning are reduced.

Description

technical field [0001] The invention belongs to the technical field of bearings, and more specifically relates to an improved thrust ball bearing suitable for heavy-load and low-speed working conditions. Background technique [0002] Thrust ball bearing is a separable bearing. The shaft ring and seat ring can be separated from the cage and steel ball components. The shaft ring, seat ring and rolling elements are separated and can be assembled and disassembled separately. [0003] For example, the application number: CN201410511160.2 relates to a thrust ball bearing, including a shaft ring, two seat rings, steel balls, and two cages. The shaft ring is installed between the two seat rings, and the two seat rings and A steel ball cage is arranged between the shaft rings, and one ring is assembled by more than three equally divided sector blocks, and a sealing groove is arranged between the seat ring and the shaft ring. The sealing groove is filled with a sealing gasket, and t...
