Influence the causes and countermeasures of IKO bearing service life

IKO bearings use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. According to the 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 condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of IKO bearing stress changes between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of IKO bearings. IKO 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 IKO bearing failure analysis factors must be considered. IKO 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 IKO bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. Metamorphic layer on the surface of a IKO bearings work in recent years research has shown that is close to the grinding process and the surface quality of IKO bearing. IKO 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, extend IKO bearings, avoid premature failure of the bearing of the sudden. Strong metal sound 1, abnormal load: select the appropriate assembly clearance and 2, the assembly pretightening bad: improve the machining precision of the shaft, improve the installation method of 3, lubricants, lubricant rules complement or use appropriate caused the channel 1, foreign bodies, rust, indentation, scar: cleaning related parts, use a clean grease 2, channel peeling: fatigue wear, replace the irregular IKO bearing different sound 1, foreign bodies, intrusion: cleaning related parts, use a clean grease 2, clearance is too large, pay attention to the coordination and choose appropriate clearance 3, steel ball scar: steel ball fatigue spalling or foreign body card, replace the IKO bearing abnormal temperature rise of 1, lubricants: too much reduce 2, lubricants, lubricants or not suitable for: add lubricant or choose a suitable lubricant 3, mating surface creep or sealing device is too large, IKO bearing outside diameter or inner diameter with surface correction, changes the shaft seal form 1, peeling off: the rotary vibration fatigue spalling, replace the IKO bearing 2, assembly: improve the machining precision of the shaft, improve installation method 3, foreign bodies, intrusion: cleaning related parts, use clean lubricant grease leak too big change color 1, lubricants, lubricant 2, foreign bodies, invasion: cleaning related parts
