Tapered roller bearing the noise effect on the failure

Impact of the rolling element and its control method is larger or type of ball bearing tapered roller bearing under pure radial load speed, due to centrifugal force is lesser, roller in the rolling body will impact the load area or race and making noises. But with the increase of rotational speed, the noise will disappear. Control method of rolling body impact sound: decrease the radial clearance, materials for use with reasonable structure and flexibility of the bearing cage. Tapered roller bearing of rolling mill and its control method for roll is cylindrical roller bearing in the harsh metal can occur in all occasions, mostly happens in large type bearing grease lubrication, and in the base oil performance degradation occurred more often in grease, almost does not occur when oil lubrication. First of all, reasonable structure design and equipped with advanced, just can have longer taper roller 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 products 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. TIMKEN 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. , the main task of the TIMKEN bearing failure analysis is based on a lot of background material, analysis data and failure forms, find out the main factors of tapered roller bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden.
