TIMKEN thrust ball bearing damage scrap of three kinds of decision criteria

Well-known TIMKEN bearing sales, quality, quality is ranked among the top of the world, with its professional running water production line, after a series process strict factory inspection, sold around the world, provide support for the industrial development of the world. The quality of the bearing is one of the most important basis of its win market recognition, then from what respect to determine the quality of the thrust ball bearing? Internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. Bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in TIMKEN bearing failure analysis share has declined obviously, but it is still one of the main influence factors of thrust ball bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. 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. Thrust ball bearing analysis, the main task of the service life is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolong the TIMKEN bearings, avoid premature failure of the bearing of the sudden. 1, bearing industrial design reasonable perfect with world-class level, strong quality guarantee its service life. Are through strict bearing forging forging, bearing heat treatment, cutting, grinding and bearing equipment series rigorous process, a variety of machining operations will affect the service life of the bearings. Which affects the quality of finished bearings, bearing failure, and is directly related. Along with the advance of science and technology to detect bearing surface inspection found that the metamorphic layer of the grinding process is fish on the surface of the bearing quality close relationship. 2, used in the thrust ball bearing manufacturing metal materials, used to be one of the main factors affecting TIMKEN bearing failure, now with the constant progress of metallurgical technology, raw materials extraction is improved, the quality of the materials have greatly ascend, now the raw material quality factor in bearing failure has obviously decreased, the problem still exists in the present stage. 3, bearing manufacturing materials is qualified and bearing failure must be a factor to consider, in usually bearing failure detection is mainly based on a lot of material, data analysis, failure conditions, the forging process, find out the main factors of bearing failure, and get rid of, convenient bearing continuous optimization, service life, and to increase the efficiency. Prolonging bearing, avoid premature failure of the bearing of the sudden. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the thrust ball bearing installation, use, maintenance, maintenance of technical requirements, the TIMKEN bearings in operation on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal.
