The importance of TIMKEN bearing import and damage degree judgment

Rolling bearing using a variety of mechanical equipment, TIMKEN bearing import conditions required by the increasingly stringent market requirements of equipment and other properties, the performance also increasingly diversified. From a large number of structure, size, select the most appropriate bearings, need a different Angle. Bearing the choice, it is generally believed that as a bearing, the difficulty of installation and removal, bearing, size and bearing of the market, such as space allows, the general decided to bearing structure. In the use of a variety of mechanical design life and comparative study of limit bearing of durable bearing, bearing has to be decided at the same time. In choosing imported bearings, bearings are often inclined to think that grease life in aging, the fatigue life of oil, abrasion resistance, low noise, also need to fully research. In addition, according to different purposes, it is a necessary choice for precision, clearance, and keep the frame structure, meet the requirements of the lubricating grease, special design of the bearing. However, choosing bearing no certain order, rules, priority should be given to TIMKEN bearing import the required conditions, performance, and related matters, especially the practical. As long as as much as possible in order to keep intact the original performance of bearing, to maintain, maintenance, in the first place, to prevent accidents, ensure the reliability of operation, improve productivity and economy. Corresponding mechanical operation and maintenance standards, on a regular basis, the best conditions. Including monitoring running state, supplement or replace the lubricant, regular check cleared. As the problem of maintenance operations, has TIMKEN bearing rotation, vibration, temperature, lubrication condition, and so on. Bearing cleaning: remove the bearing repair, the appearance of the record for the first time to import bearings, confirm the amount of residual lubricant, sampling inspection after the use of lubricants, cleaning bearing. As a cleaning agent, general use gasoline, kerosene. Remove the bearing cleaning, washing and fine washing thick, be placed in a container, metal openings at the first, don't make direct contact with TIMKEN bearing import containers of dirt. Rough washing, if the bearing rotating dirt, damage to the bearings rolling surface, it should be noted. In the crude oil washing, brush with the brush to remove grease, viscous material, generally clean, wash into the fine. Fine wash wash oil is in the side of the bearing rotation, while carefully cleaned. In addition, cleaning oil must be kept clean. Bearing maintenance and judgment: to determine whether remove bearing can be used to check the bearing after cleaning. Check the raceway, raceway, surface state, cage wear, imported bearing clearance and to increase the dimension precision, has not damage, abnormal. Non separation of small ball bearings, inner ring, with one hand support level, rotate the outer ring to confirm smoothly. Separation of tapered roller bearings and bearing, rolling your body, the outer ring raceway surface inspection. Large bearings, because they can't rotate with the hand, pay attention to check the raceway of roller and cage, metope, such as the appearance, the higher the importance of TIMKEN bearing import and check more carefully. By TIMKEN bearing failure and degradation, performance status parameters to judge and predict the performance, reliability, and use bearing on the part of the abnormal situation, cause and degree of risk identification and judgment, decided to repair and improve the method of comprehensive technology. Therefore, bearing fault diagnosis technology is not a simple fault detection ( Or monitoring) Responsible for counting instrumentation of technology, also is not simple. Accurately and quickly and effectively to collect signals, data processing, manual or automatic identification and judgment. In order to confirm the repair cycle science, but also according to the mechanism of all kinds of fault, to fatigue, wear life necessary test and estimate. TIMKEN bearing import availability judgment, mainly considering bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. If there are the following defects cannot be used again, new bearing must be replaced. Inner ring and outer ring, rolling element and cage on any one have crack or gap. 1, ring, rolling body fracture on any one. 2, rolling on the pavement, guard, rolling body CARDS have a significant injury. 3, keep wear significant or rivet significant relaxation. On page 4, raceway and rolling body rust, injury. On page 5, raceway and rolling body severe creasing and mark. 6, inner ring diameter or outer diameter surface has obvious creep. 7, due to the hot color change is obvious. 8, the TIMKEN bearing grease sealed, sealing ring or dust cover breakage is obvious.
