Rolling bearings use a variety of mechanical equipment. The increasingly stringent conditions required by SKF bearings, the equipment and other properties required by the market, and the performance is also becoming more and more diversified. In order to select suitable bearings from a large number of structures and sizes, different angles are required. When selecting SKF bearings, it is generally believed that the SKF as a bearing, the difficulty arrangement of installation and removal, the size of SKF bearings, the market of bearings, and other space allow, generally determine the SKF Bearing structure. The design life of various machines and various durable SKF bearings limit the comparative study of SKF bearings and determine the bearing size at the same time. In choosing SKF bearings, bearings tend to think that the grease life, fatigue life, wear resistance and low noise also need to be fully studied.
Accuracy, clearance, cage structure, grease, etc. However, there is no certain order and rules for the selection of bearings. Priority should be given to the conditions, performance and related matters required by SKF bearings, especially practical. As long as the bearings in order to maintain intact original performance as much as possible, they should be maintained and maintained in the first place, so as to prevent accidents, ensure the reliability of operation, improve productivity and economy. Corresponding mechanical operation and maintenance operation standards, regular and appropriate conditions. This includes monitoring the operating status, replenishing or changing lubricants, and regular inspection and removal. As a problem of maintenance operation, SKF Bearing rotation sound, vibration, temperature, lubrication conditions, etc.
Remove the bearing for repair, record the appearance of SKF Bearing for the first time, confirm the remaining amount of lubricant, and clean the bearing with the lubricant used after sampling inspection. As a cleaning agent, gasoline and kerosene are generally used. Remove the bearing for cleaning, cleaning and fine washing, place it in the container, put the metal mesh bottom of the container so that it does not directly contact the dirt of SKF Bearing. Rough washing, if the bearing rotates dirt and damages the bearing rolling surface, attention should be paid to it. In crude oil cleaning, brush with a brush to remove grease, viscous materials, general cleaning and washing into a fine. Fine washing is to wash the oil, rotate the bearing on one side and wash it carefully at the same time. In addition, the cleaning oil must be kept clean
Determine whether it can be used to check the bearing after cleaning and remove the bearing. Check the raceway, raceway, surface condition, cage wear, SKF Bearing Clearance and improvement of dimensional accuracy, irrelevant damage and abnormality. Non separable small ball bearing, inner ring, support level with one hand, rotate the outer ring to confirm smooth. Tapered roller bearings, split bearings, can roll the body, and the outer race raceway surface has been inspected. For large bearings, because they can’t rotate by hand, pay attention to check the raceway, cage and wall of the rolling element, such as appearance. The importance of higher SKF bearings should be checked more carefully.
