Single-row inner ring thrust ball bearing

Abstract

The invention discloses a single-row inner ring thrust ball bearing, and relates to the technical field of bearings. The single-row inner ring thrust ball bearing comprises a bearing inner ring, and aroller journal is arranged in the bearing inner ring. According to the single-row inner ring thrust ball bearing, guide grooves and limiting columns are arranged, and under the limit of the guide grooves and the limiting columns, the bearing inner ring follows the rotation of the roll journal, so that the out-of-step rotation of the bearing inner ring and the roller journal is avoided, and thus the bearing inner ring and the roller journal are rubbed, and the service life of the single-row inner ring thrust ball bearing is lost; an oil inlet hole is formed, lubricating oil is poured into theoil inlet hole, and under the action of an annular oil storage cavity and oil outlet holes, the lubricating oil is uniformly lubricated from the oil outlet holes through centrifugal force through therotating bearing inner ring, so that the problems that most of existing bearing inner rings and roller journals slide relatively, the frictional heating of the bearing inner rings and the roller journals is generated, and the service life of the bearings is influenced, and most axial bearings in the prior art cannot effectively uniformly lubricate steel balls during lubrication, and the use of thebearings is affected are solved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a single row inner ring thrust ball bearing. 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. [0003] The Chinese patent publication number is CN2251645Y (the application number is CN95211486.0) discloses a kind of single-row inner ring thrust ball bearing in the open document, and the connection of most axial bearings and roll journals in existing use usually passes the bearing through When the tool is inserted into the roller journal, the bearing inner ring and the roller journal will rotate out of synchronization when the roller journal is running, causing the bearing inner ring and the roller journal to slide relative to each other, so that the friction between the bearing inner r...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a single-row inner ring thrust ball bearing, which solves the problem of relative sliding between the inner ring of most existing bearings and the roller journal, so that the friction between the inner ring of the bearing and the roller journal generates heat and affects the service life of the bearing. impact, and most of the existing axial bearings cannot effectively lubricate the steel balls evenly during lubrication, which affects the use of the bearings
