Taper roller bearings KOYO preventive maintenance and reduce the noise of the lubrication and maintenance of the three methods

First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished product tapered roller bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. KOYO bearing materials of metallurgical quality were the main factors influencing the premature failure of the tapered roller bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. KOYO bearing, the main task of the failure analysis is based on a lot of background material, analysis data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden. Remove the bearing under repair, the first record the appearance of the bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, can injure the rolling surface of the tapered roller bearings, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. Of KOYO bearing equipment preventive maintenance, operation and peripheral parts change was removed when the suspension bearing checking, discriminant times demand, in turn, the condition of bearing parts can use again and record using the good from the bad. In order to find out and query to visit the amount of residual lubricant, sampling, to clean the bearing well. 一个。 Inner and outer ring, rolling body, confrontation and hear any crack and present pieces. b。 Inner and outer ring, rolling body and anyone with a shed. c。 Raceway surface, guard, significant injury of roller. d。 Confrontation of badly worn or loose rivet fierce. e. Raceway surface, rust and roller has a scar. f。 Had a remarkable indentation rolling surface, rolling body and make a mark. g。 Inner ring diameter or outer diameter on the creep. h。 Hot color changing fierce. 我。 Sealing ring of tapered roller bearing grease and dust cover damage to serious.
