Bearing positioning: high-speed bearing carries dust harm

Rolling bearing radial clearance refers to a fixed ring, and the other a ring in the direction perpendicular to the bearing axis, the position of extreme to the other extreme position of mobile. & #; Bad lubrication lubrication on the service life of bearing and friction, wear, vibration and so on have important influence, good lubrication is necessary for normal operation of the bearing condition. Exchange is divided into two types of wheel bearing type is only need to replace a bearing alone is ok, but the maintenance difficulty slightly larger; The other type is replace bearing assembly, maintenance difficulty is very small! Some time ago, mechanics made the teacher give small make up a buick excelle fault is introduced. Within the bearing seat is equipped with two axle bush above, assuming that A and B on both sides of the vertical vibration in phase, if A and B with the same on both sides of the bearing stiffness, radial vibration will not stimulate the axial vibration. C heavy load, in this way, the matching of the inner ring and the shaft may be loose, the matching of the outer ring and the hole may be tight, so when choosing cooperate, must consider the influence of the bearing operating temperature. Roller broken when roller broken, according to the degree of its broken and scattered will appear different degrees of rotation is not flexible, until it is difficult to rotate both messy random vibration sense or sound. First due to the elastic modulus of the ceramic is higher than steel, when the stress is not easy to deformation, thus to improve work speed, and achieve higher precision, main use ceramic bearing has a high temperature resistant, cold resistant, wear resistant, corrosion resistant, magnetoelectricity insulation resistance, oilless self-lubrication, features such as high speed. But now the track no little lowe: anything you this broken very simply, conditional word do crystal like contrast tomorrow: xiao xin: forging, there is a hole or material existence impurities: tomorrow see bearing area years: excuse me, the rolling screw bearing and rolling of strip steel bearing on the material tomorrow: is there a difference? Work roll bearings and back-up roller bearing years: little lowe: supporting roller of hot rolled strip steel support roller now many are oil film bearing tomorrow: and then see if rolling body both face serious wear and tear, or worn surface years: bearing area and the normal place no difference, surface is very smooth, almost no wear and tear, cross section is chamfering in creasing tomorrow: this is a short time damage? Cage? Time: it could be broken fragments in years: the cage no bad and no deformation. & emsp; & emsp; Some related equipment such as electric motors, generators used in rolling bearing, in the process of use is likely to be affected by the current through the, this will not only damages to the rolling element and raceway of bearing, but also will affect the performance of the grease. Countermeasures: grinding trunnion, get appropriate coordination between the shaft and bearing inner ring, due to the material of bearing box hole stress after the aperture is too soft, cause the outer ring hole slippage in box. Whether eccentric shaft rapid roll, the voltage is delayed, as a result of the axial if direct contact with shaft bearing on either side of the form a closed loop, created a shaft current. Bearing chamber is a do not apply oil or grease if must apply to control shall not be in bearing indoor product, paint, rust preventive rust paint is characterized by multiple in sealing type motor.
