Iron, Ken bearing test of some importance

Rolling bearing using a variety of machinery and equipment, iron, Ken bearing 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 one of the 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 selecting 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. But, choose iron bearing no certain order, rules, priority should be given to bearing 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 operation, have bearing rotation, vibration, temperature, lubrication condition, and so on. Bearing cleaning: remove the bearing repair, record the appearance of the bearing, for the first time confirmed 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 the bearing of the dirt of the container. 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 iron Ken bearing inspection and judgment: to determine whether remove bearing can be used to check the bearing after cleaning. Check the raceway, raceway, surface state, cage wear and 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 bearing, check more carefully. When the detection of rivet head main observation is there a link between slanting, easing the welding position is not correct. The welding quality. Welding point is too small, do you have any welding or welding, solid ball card caused problems. In the process of bearing test need to pay special attention to. There are also some problems needing attention. Here to share with you many years of experience, in the local bearing detection. Iron, Ken bearing on the environment of the first check should be in the light environment, it is the best astigmatism, in order to better bearing, was observed on the surface appearance and no crack and other anomalies. Such as cloud of mechanical wear and scratches, touch pressure in the process of bearing equipment can lead to shift, and result in poor equipment location, lead to the shape of the bearing flat load and stress concentration, reduce precision and service life. In addition to pay special attention to the work environment or the pollutants in the water, which is most likely to lead to bearing rust, rust iron, lead to bad bearing installation, early wear and tear, will lead to more serious waste is a direct relationship. Therefore, it is important to pay special attention to in water to moisten of course.
