172019-07Method of maximizing the service life of a bearingBearing heat treatment is directly related to the subsequent processing quality, which ultimately affects the use performance and life of the parts. At the same time, bearing heat treatment is a major energy consumer and a major polluter in bearing manufacturing. The heat treatment equipment of the bearing directly affects the quality of the bearing heat treatment, as well as energy consumption and pollution. In recent years, with the advancement of science and technology, the development trend of heat treatment technology is mainly reflected in the following aspects: …

212019-05Bearing operation checkAfter the bearing is installed, check the operation in order to check if the installation is correct. The small machine can be rotated by hand to confirm whether the rotation is smooth. The inspection items have poor operation due to foreign matter, scratches, and indentations. The installation is poor, the torque generated by the mounting is not stable, and the torque is too large due to too small clearance, installation error, and sealing friction. Wait. If there is no abnormality…

102019-04Bearing repair and judgmentWhen judging whether the removed bearing can be reused, check the bearing after cleaning, carefully check the condition of the raceway surface, the rolling surface, the mating surface, the wear of the cage, whether the bearing clearance is increased, and whether the dimensional accuracy is degraded. Damage, abnormality. For non-separable small ball bearings, use a one-handed flat end inner ring and rotate the outer ring to check if it is smooth. Separate bearings such as tapered roller bearings, can be rolled…

062019-03Bearing cleaningWhen repairing the removed bearing, first record the appearance of the bearing, confirm the residual amount of lubricant, and clean the bearing after sampling. Gasoline and kerosene are commonly used as cleaning agents. The cleaning of the removed bearing is divided into rough washing and fine washing. The metal mesh is placed in the container so that the bearing does not directly contact the dirt in the container. In rough washing, if the bearing rotates with dirt, it will damage the rolling surface of the bearing and should be noted. In rough washing…
