Extend the life of the TIMKEN angular contact ball bearing using cycle - bearing knowledge from maintenance

Angular contact ball bearing, the main task of the failure analysis 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 sudden TIMKEN bearing early failure. First of all, reasonable structure design and equipped with advanced, just can have longer angular contact ball bearing life. 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 TIMKEN 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. 1, pay attention to the installation of the bearings bearing installation is correct, affects the precision, life and performance. Therefore, the design and assembly department for the installation of the bearing products to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Clean the bearing and the bearing connection parts; ( 2) Check the size of the interrelated parts and finishing; ( 3) Installation; ( 4) After installed bearing inspection; ( 5) Supply of lubricant. Carefully prepare bearing installed this five step 2, alignment, alignment after TIMKEN bearing installed, if not done carefully alignment, alignment can lead to bearing suffered another load, friction, and vibration. These could accelerate fatigue and reduce the service life of bearing products, and it might damage the other machine parts service life. In addition, the increase of vibration and friction could significantly increase the risk of energy consumption and premature failure. 3, the basic conditions for monitoring during the period of using, often should basic external conditions of bearing operation monitoring, such as temperature, vibration and noise measurement, etc. Bearing experts point out that these regular check will help identify potential problems and to prevent unexpected machine to suspend the phenomenon, make the production plan, improve plant productivity and efficiency. 4, again the lubrication in the process of operation, TIMKEN bearing requires correct lubrication again, perfect its performance. Bearing lubrication products, divided into grease lubrication and oil lubrication. In order to make the bearing products function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. But there are grease lubrication can simplify the structure of bearing around specialty. Remove the bearing under repair, the first record the appearance of the bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, can injure the rolling surface of the tapered roller bearings, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. Angle contact ball bearing equipment preventive maintenance, operation and peripheral parts change was removed when the TIMKEN bearing to suspend the checking, discriminant times demand, in turn, the condition of bearing parts can use again and record using the good from the bad. In order to find out and query to visit the amount of residual lubricant, sampling, to clean the bearing well.
