INA drill bearing failure reasons of high temperature and the processing method

INA bearing failure reason has a lot of, in the process of design and manufacture of some operation, will affect the efficiency of the drill bearing, generally is less easy analysis judgment, under normal circumstances, can be used from the factors, and internal factors to determine. On analyzing the factors mainly look, use, maintenance, repair and maintenance to install the related operations is not conform to the requirements of the bearing of the official. Installation conditions is to use one of the primary factor of the drill bearing factors, bearing is often caused by improper installation and the force states of INA bearings between various parts of a complete set of changes, bearing in the abnormal state run and early failure. 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, when the bearing temperature rise, the primary judgment can have no false move do first, and if the temperature is indeed rising, do the following treatment: (when immediately 1) Raid cooling water pressure, water flow and pipeline system can be generally bearing. If water is likely to be lower filter blockage, means less than timely disposition of cylindrical hole bearing heat removal, can stop treatment, when confirm can work to do, then put into use. ( 2) When a raid of governor oil pressure, if low oil pressure can lead to cooling water hydraulic valve closed. ( 3) Raid can no homophones set-contained INA bearings are of spherical ball, and detect bearing degree can not very. ( 4) Can take oil sample check color no change, the drill bearing and test to see whether a variable. If confirm the degradation, when downtime to change new oil. ( 5) Can raid the oil standard oil level is general, if is general, raid tank emptying valve will shut. Bearing if it is not matter, when filling oil, if the sealing rubber gasket of oil leakage, when stopping treatment. Structure design is reasonable and advanced, will have a long bearing life. The drill bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly and other multi-channel processing process. 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. Metamorphic layer on the surface of a INA bearings work in recent years, research has shown that the surface quality of the grinding process and its close then, bearing the main reason for 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, and extend the INA bearing, to avoid premature failure of the attack.
