Timken bearing import: bearing vibration failure analysis and case

Oil operation, can be in the mating surfaces, makes the company bearing pads, material is steel, models for MCFen - Methyl amino acetonitrile dplate, complete gasket and fracture morphology is shown in figure. Com/x/page/SVFQ, heat removal of the operation method is the coil winding to directly to the inner ring of the rolling road to heat expansion, make the bearing easily removed. 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. Wheel hub unit usually driven and rotate the outer ring up for the front or rear wheel, a small rotation of the inner ring installation on the flange inner ring, to great extent improve the bearing capacity. After find out the reason, redrawing the come on line, because of the severe high temperature fan cooler fouling frequent situation on the bearing temperature is too high in the branches have been met. Cases like bearing under the running condition will not result in a direct seal on the shaft friction wear, but bearing bush denier problems or excessive wear, because of the sealing part is made of polyurethane has good wear resistance, the motor shaft position extremely prone to wear and tear. Self-aligning roller bearing main use: papermaking machinery, speed reducer, railway vehicle axle, rolling mill gear box, roller mill, crusher, vibrating screen, printing machinery, woodworking machinery, all kinds of industrial reducer, vertical arrange ushering self-aligning bearing. Lubricating oil tubing for oil in water supply, or from oil hole to axis bearing shell oil, due to the seal will scrape the lubricating oil, oil lubrication is not applicable to nonporous sealing ring bearing. Oil-way don't blocked, the moving cone of the installation process, it is important to pay special attention to the eccentric shaft sleeve, spherical watts, tapered bushing, frame straight dust on the surface of the bushing, etc. After quenching process of bearing steel in small amounts not dissolve carbide helps to improve the wear-resisting degree of bearing, also helps to get fine grain cryptocrystalline martensite, so as to improve the bearing of toughness and fatigue strength; Carbide particle size influence on bearing life is very big also, carbide particles smaller than the bearing steel. Also asked that the shipowners' docking replacements as soon as possible stern bearing and seal, mechanical cleaning such as grinding, polishing and blasting shot peening, should avoid to use carbon steel brush, to prevent surface rust. & emsp; & emsp; Because of the generator rotor and bearing inner ring friction, the high temperature of bearing and generator shaft front of bearing inner oil evaporation, gasification, and generate large amounts of combustible gas.
