One-way needle bearing, bearing outer ring production process

Due to the use of each part in the interaction, making fixed bearing outer ring ( Or inner ring) Retaining ring and the bearing outer ring on the end cover of shoulder will produce quantitative wear, these ordinary wear and tear, sum up and also can make the shaft has a big gap, can also lead to shaft system to make up. Grinding wheel granularity is too thick or too soft; If the problem affects to normal driving, it would have to trim, unless you want to experience every day to drive the feeling of fear, grinding wheel dressing too fast or finishing clearance is too large; , as is the arrange ushering bearing and self-aligning bearing mostly, and it is the inner ring is more tight sleeve bearing cylindrical hole. According to different equipment, different running condition, different wear conditions, adopt corresponding repair process, can be fast, simple and effective to repair, especially due to the high polymer material rolled back, always maintain % contact area, avoids the production of fit clearance, make the repaired equipment life even more than new equipment, fundamentally solve the problem of ball mill axial wear. Master not only the test of welding technology, bearings and its peripheral accessories should be kept clean, especially the dust and dirt, tools and working environment must be clean. 'Skid' is used to show that the severity of the rolling bearing is sliding and sliding when keep the actual speed is equal to the speed cage theory, bearing no skid and the skid degrees to zero; As long as you keep the actual speed is lower than the theoretical, bearing the skid, when keeping the actual speed is zero, skid degrees for %. Today, small make up for all the popular science knowledge about wheel bearing grease, open the drain valve for stern tube, stern tube oil contains some metal chips, as shown in figure. Lubrication effect is better, the lubrication efficiency is higher, in the case of lubricant is less a good lubrication effect, and compressed air extent, reduces the temperature of bearing internal and improve the service life of the bearing, greatly reduces the maintenance workload, the resulting downtime due to lubrication and reduce greatly, improve the production efficiency. Generator bearing generator bearing cylindrical roller bearing and deep groove ball bearing, in the case of poor lubrication, bearing is likely to happen as shown. Owner for the last time didn't listen to repair master replacement release bearing also feel very regret, use F metal repair material will wear position filled and slightly bigger than the wear volume. Surface treatment: use the oxygen acetylene on bearing surface baked oil processing, until no spark splash, then put the bearing surface oxidation into clean, bared metal original; 。 In addition, during the installation process, due to the bearing parts contact with other belt Angle of rigid objects, and the bearing parts of the workspace skinned the depth, width, length but different groove OARS called cut or scratch, if the number of rolling contact surface between, falling into local damage, foreign small particles impurities or lubricating oil is combined with the two between the sliding surface, so that the parts work surface group of tiny scratches, called scratch. Six, rust corrosion phenomenon: all or partial surface rust, pitch roller with rust, eight, wear phenomenon: wear surface, the change of size, many accompanied by grinding and grinding crack.
