The difference between bearing and air conditioning: bearing zv2 and ZV3 big

Due to the installation of the ball or roller bearings, the bearing gap is too small, in use process by severe shock, lubricants in hard material such as mixed with the iron filings, cause the ball or roller broken. Bearing failure analysis method based on the analysis of bearing failure process, often encounter many complicated phenomena, various experimental results may be contradictory or primary and secondary is not clear, this needs after repeated experiments and theories, in order to obtain sufficient data or reverse. Set set too tight lock, a new type of bearing grinding of bearing accuracy problems bearing is mainly composed of machine tool accuracy, precision fixture precision grinding process parameters and composite formation. After early tile body with copper alloy casting, switch to the steel back of brass, used nodular cast iron manufacturing, railway vehicle on the anti-friction bearing alloy, commonly known as white metal, lead antimony tin alloy. Progress to impact resistance, as a bearing material using nickel chrome steel, chrome molybdenum steel, chrome molybdenum steel, adopt carbon quenching, make steel from the surface to the depth of the right has a soft layer. If the equipment downtime is too long, especially during the winter low temperature circumstances, bearing during operation sometimes rustling 'hissing sound, with the bearing radial clearance to smaller and smaller work grease penetration. & emsp; & emsp; After hot working such as malleable cast stainless steel bearing, the surface often has a layer of oxide skin, lubricant, or oxide pollution pollutants including carbon graphite, molybdenum sulfide and oxide, etc. & emsp; & emsp; Explosion-proof motor bearing high solution, regular maintenance and maintenance, should add full of grease/oil chamber or add lubricant to standard oil level line, avoid running motor bearing short of oil. CD— — Contact Angle for, or are not suitable for: add lubricant or choose a suitable lubricant fitting surface creep or sealing device is too big: bearing outside diameter or inner diameter matching surface correction. The surface finish, this allows a P precision grade, we this product also won the German Humboldt, chengdu lijun and citic heavy industry recognition is recommended. Moistens the quality influence on bearing life bearing can long time reliable use without lubrication quality, rolling mill bearings in normal operation when subject to various friction, the outer ring raceway load area is under serious internal friction parts, oil bearing operation will exist in the process of the radial clearance, roller rolling will only in the problem of load area, this is the load section will be in a state of rolling and sliding, roller from the load section into the process of load area, roller speed will increase suddenly, in the process of speed jump, roller and raceway friction, at the same time also will inherit from the impact load in the process of steel rolling. So in the choice of the bearing grease performance requirements? Good lubricity to keep between shaft and bearing contact surface have a uniform oil film, and in the main shaft impact load of oil film start or stop the movement also not dent, keep good lubrication performance, play to reduce friction and friction heat, lowering the temperature rise of the main shaft, guarantee machining accuracy, oil has good lubricity.
