Oil leakage prevention supporting bearing

Abstract

The invention discloses an oil leakage prevention supporting bearing. The bearing comprises an inner ring, an outer ring, a middle hole, a middle groove, a rolling body and a retainer, wherein the middle hole is formed in the middle of the inner ring in a penetrating mode, the outer ring is arranged on the outer side of the inner ring, the middle groove is formed in the middle of the inner sides of the outer ring and the inner ring, a sliding ring is arranged at the bottom of the retainer, the bottom of the sliding ring is clamped in a sliding groove, an oil injection hole is formed in the topend of the retainer, and a fixing plug is clamped in the oil injection hole. When the oil leakage prevention supporting bearing is used, waste of work caused by throwing out of lubricating oil duringrotary centrifugation is avoided, meanwhile, impurities cannot enter a rolling body, uniform oil injection work can be conveniently carried out on the outer portion of the rolling body, the service life of the whole rolling body can be prolonged, frequent oil injection work is not needed, and the phenomenon of waste of lubricating oil is avoided.

Description

technical field [0001] The invention relates to the technical field of support bearings, in particular to an oil leakage-proof support bearing. Background technique [0002] The support bearing is a new type of mechanical component. It is composed of inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing that can bear comprehensive loads. It can bear large axial and radial loads and overturning moments at the same time. It is widely used in the industry and is called "the joint of the machine". It is an important transmission necessary for a machine that needs to perform relative rotary motion between two objects and simultaneously bear axial force, radial force, and overturning moment. Parts, there are many types and quantities of support bearings on the existing market, but there are still some problems when they are used; [0003] 1. Traditional support bearings need to be oiled before use to ensure that the surface of the rolling element is...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an oil-leakage-proof support bearing to solve the problem that the support bearings on the market currently on the market proposed by the above-mentioned background technology are inconvenient to carry out uniform oil filling work, and oil leakage often occurs , and the problem that the rolling elements cannot be well dust-proof
