Installation of rolling bearing force application effects on life

Factors influencing the service life of rolling bearings may has a lot of, can be used from the factors and internal factors for further instructions. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. According to rolling bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing 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. 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 of operation and the service life of the early end bearing installation of applying big or small will influence the performance and bearing life, also can cause bearing damage, the following is the need to pay attention to in the process of applying the four skills. 1. The size of the work should be a smooth uniform, can't have impact, it will require the use of oil pressure or pressure stable tension or can use tools, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. It is best to use copper or copper hammer hammer. 2. Applying to continue to work, for example, when installing a bearing in the bearing fit into the correct position to stop work, guarantee the ring ( Washers) The end face of landing on a hole or shaft shoulder end, neither packed too tight, nor does not reach the designated position. 3. Work together as much as possible through the axis of the bearing, this requires the screws even symmetry and smooth, by spherical or parallel to the axis force application. 4. Avoid by applying pressure roller, which requires the inner ring (installation Axial circle) When applying pressure through the inner ring and outer ring installation when applying pressure through the outer ring. As long as do bearing installation when the size of the wire should be smooth uniform, can't have a shock, applying to continue to work, the matters needing attention, then there will be no damage to the bearings during installation. Rolling 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 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. Rolling 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. Analysis, the main task of the service life of rolling bearing 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, prolonging bearing, avoid premature failure of the bearing of the sudden.
