Thin wall bearings: car how to judge bearing is broken

& emsp; Gray cast iron and cast iron ordinary gray iron or with nickel, chromium, titanium alloy wear resistant cast iron, or nodular cast iron, can be used as a bearing material. The surface roughness of the workpiece can not meet the requirements of the main reason is:, screw air compressor host bearing is damaged, please come air compressor professional timely maintenance, workpiece speed too high or the workpiece axis and spindle vibration; , normally, the temperature of the bearing with operation began to slowly rise,. . . Reach a steady state after hours. After quenching and tempering hardness and uniformity, high wear resistance and contact fatigue strength, GCr steel is an alloy content is less, has a good performance, wide application of high carbon chromium bearing steel. Because with bearing and the shaft is match to the inner ring and the shaft bearing, using the basic hole system, original bearing should be completely to zero, in actual use, we can also think so, but in order to prevent the bearing inner ring with the small size limit shaft when inner ring rolling, the surface of the shaft damage, so we have to a few mu of bearing inner ring under partial tolerance to protect inner ring does not rotate, so bearing a selected transition fit is ok, even if is to choose the transition fit also cannot exceed the amount of interference. Is there will be no sound! For this maintenance, SKF bearing failure scale factors in advance: improper lubrication: % of bearing failure reason in advance. Sauvy carbon technology of polymer materials, kinds of cold welding ( Binding) Technology, online repair process does not produce high temperature, good to protect equipment from damage of ontology, and in the process of repair is not restricted by axial uneven wear amount. As bearing of major parts of the machinery and equipment, our daily maintenance is inevitable, then let us feel headache thing is: 'bearing the Laos during operation is pronounced as abnormal voice' for this, a lot of technical personnel also know many factors can cause bearing when running in different sound, but not enough are summed up, according to the understanding of the bearing use, summarizes the factors bearing abnormal sound, hope to be of help. In keeping the shelf fixed small with cobalt or iridium ( CoIr silk source, using the inverse square law ( Which has reached a certain point strength is the square of the distance from the source to that point) Cage in the work of the principle of measure speed, bearing to discover whether a skid, and can calculate the skid. Applicable: oil cup drip lubrication is suitable for low speed and light load at a lower temperature, oil bath, Oiled) Lubrication, lubrication, but oil is not easy to adjust, no filter easy to impurities in the fuel tank into the bearing internal damage to the bearings. By the influence of motor vibration of motor rotor, pulley and so on rotational imbalance can also cause vibration, dynamic balance, must therefore be carefully into the good reduced the amplitude of the motor to about mu. The bad working condition is the main cause of premature failure of the rolling mill bearing, as conditions mainly including the load bearing the operating conditions and their distribution, lubrication, sealing, speed transmission, working temperature, cooling condition, such as bearing quality and the use of parts of the same circumstances, different working condition, its service life will there is a big gap. With quiet operation, low cost, can carry on the radial load and axial load, the advantages of low friction, low calorific value, high speed turn; The drawback is that unable to bear impact load or radial and axial load.
