In order to fully utilize the bearings and maintain their proper performance for a long time, regular maintenance (regular inspection) must be carried out. Through proper periodic inspections, early detection of failures and prevention of accidents are important to improve productivity and economy. 1, cleaning When the bearing is removed for inspection, the appearance record is first recorded by photography. Also, verify the amount of lubricant remaining and sample the lubricant before cleaning the bearings. a. The cleaning of the bearing is carried out by rough washing and fine washing, and a metal mesh frame can be placed on the bottom of the used container. b. When rough washing, remove the grease or adhesive with a brush or the like in the oil. At this time, if the bearing is rotated in the oil, be careful that the rolling surface will be damaged by foreign matter or the like. c. When cleaning, slowly rotate the bearing in the oil and carefully. The commonly used cleaning agent is neutral non-aqueous diesel or kerosene, and a warm alkali liquid or the like is sometimes used as needed. Regardless of which cleaning agent is used, it is often filtered and kept clean. Immediately after cleaning, apply anti-rust oil or anti-rust grease to the bearing. 2, inspection and judgment In order to judge whether the removed bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and seal. Regarding the inspection result, it can be judged by the use of the conventional bearing or the master bearing. The criteria for judgment vary depending on mechanical properties and importance, inspection period, and the like. Bearings must not be reused if they are damaged and must be replaced. 1) Breakage and defects of bearing components. 2) Peeling of the rolling surface of the raceway. 3. Bearing fault identification method It is important to identify or predict whether a bearing in operation is faulty without disassembly inspection, which is important for improving productivity and economy. The main methods of identification are as follows: 1) Identify by sound It takes a lot of experience to identify by sound. Must be fully trained to be able to identify bearing sounds and non-bearing sounds. To this end, the work should be carried out by a dedicated person. The sound of the bearing can be clearly heard by attaching it to the housing with a listener or a listening stick. 2) Identification by working temperature This method is a comparative identification method and is limited to occasions where the operating state does not change much. For this purpose, continuous recording of the temperature must be carried out. In the event of a fault, not only does the temperature rise, but irregular changes occur. 3) Identification by the state of the lubricant Sampling analysis of the lubricant is judged by whether or not the degree of contamination is mixed with foreign matter or metal powder. This method is particularly effective for bearings or large bearings that cannot be viewed close together.
