Bearing for electric equipment with long service life

Abstract

The invention provides a bearing for electric equipment with long service life. The bearing comprises a bearing body, a fixed base and a rotating body; the bottom of the bearing body is fixedly mounted at the top of the fixed base; the rotating body is fixedly mounted on the inner wall of an inner ring of the bearing body; the top of the fixed base is fixedly connected with a front side plate; andthe front side plate is positioned in front of the bearing body. The bearing for the electric equipment with long service life is provided with a front side plate, a back side plate, a left side plate and a right side plate for preventing external dust of the electric equipment from entering the bearing body and attaching on the surfaces of balls to cause increment of friction between the balls;and meanwhile, through matching arrangement of a first dustproof net, a second dustproof net, a third dustproof net and a fourth dustproof net, the dust is prevented from entering the internal of thebearing body, the tension of the front side plate, the back side plate, the left side plate and the right side plate is reduced, and the service life of the bearing body is prolonged.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing for electric equipment with long service life. Background technique [0002] Bearings are 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. The early form of linear motion bearings was to place a row of wooden poles under a row of pry plates. Modern linear motion bearings use the same working principle, sometimes with balls instead of rollers. The simplest swivel bearing is the bushing bearing, which is just a bush sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which replaced the original bushings with many cylindrical rollers, each rolling element acting like a separate wheel. With the development of science and technology, bearings are used more and more widely, e...
