The thick child is placed in the container, and the first metal mesh bottom is placed in the container so that it does not directly touch the dirt of the imported bearing. Under normal circumstances, the main form of failure of rolling bearings is fatigue spalling under the action of alternating stress, bearing and loss of bearing accuracy due to friction and wear. In addition, there are other reasons such as cracks, indentations, rust, etc. The main parts of sliding friction are: the contact surface between the rolling element and the raceway, the contact surface between the rolling element and the cage pocket, between the cage and the ring guide rib, and the roller end surface and the ring guide Wait between the ribs. The application of material surface strengthening technology can not only better solve the differences in the structure and requirements of the surface and the core, but also further enable the surface to obtain some special working performance to meet the performance of the bearing working under specific conditions. Therefore, rolling bearings should have high resistance to plastic deformation, less friction and wear, good rotation accuracy, good dimensional accuracy and stability, and long contact fatigue life. Cleaning of imported bearings: remove the bearings and Mechanical ball bearing repair them, record the appearance of the imported bearings for the first time, confirm the remaining amount of lubricant, and clean the bearings after sampling the lubricant used after the inspection. Fine washing is to wash the oil on one side of the bearing rotation, while carefully cleaning. The existence of sliding friction in bearing rolling bearings inevitably makes bearing parts wear. Requirements. Whether the choice of materials for rolling bearings is appropriate will have a great impact on its performance and life. Therefore, the bearing steel is required to have high wear resistance. Remove the bearing for cleaning, cleaning and fine-washing. that cause abnormal damage to the bearing.. If the imported bearing rotates with dirt and damages the bearing rolling surface, care should be taken. The basic material requirements of rolling bearings depend to a large extent on the working performance of the bearing. In crude oil cleaning, use a brush to remove grease, viscous materials, and generally clean and wash fine.There is a big difference between the working surface and the core of imported bearing parts in terms of state, structure and performance requirements, and the overall heat treatment often makes it impossible to take into account, and the potential of the material cannot be fully utilized. When rolling bearings work normally, in addition to rolling friction, there is also sliding friction. As a cleaning agent, gasoline and kerosene are generally used. This is of great significance in the development of modern science and technology. If the wear resistance of the bearing steel is poor, the rolling bearing will lose its accuracy prematurely due to wear or decrease the rotation accuracy, which will increase bearing vibration and reduce its life.
