About bearing maintenance, cleaning and maintenance, lubrication and installation. For as long as possible in good condition to maintain the performance of the bearing was required to maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, the rotation of the Taipei TPI bearing state of sound, vibration, temperature, lubricant and so on. A bearing cleaning remove TPI in Taipei, Taiwan, TPI bearing repair, the appearance of the first record Taipei TPI bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, wash the TPI bearing of Taipei. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the Taipei TPI bearing cleaning, rough washing and fine washing, respectively in the container, first put on the metal mesh at the bottom of the bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, 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. Bearing inspection and judgment: in order to judge whether the bearing of the removed can use, check after wash bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Separation of tapered roller bearings and bearing, rolling body, the outer ring raceway surface can be respectively. Large bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of bearing high must check carefully. Second, bearing lubrication bearing lubrication purpose: rolling bearing lubrication purpose is to reduce the bearing internal friction and the friction losses, prevent burning stick, its lubrication effect is as follows. ( 1) Reduce friction and friction losses. In the form of bearing ring, rolling body and touch each other part of the retainer, prevent metal contact, reduce friction and wear. ( 2) Extend the fatigue life. Fatigue life of rolling bearing, in the rotation, good lubrication performance of the rolling contact surface, are extended. On the contrary, the oil viscosity is low, the thickness of lube film is not good, is shortened. ( 3) Discharge the friction heat and cooling. Circulation method to oil and so on can oil discharge by the friction heat, or by an external sound of heat, cooling. To prevent hotbox, prevent aging oil itself. ( 4) Other: have inside to prevent foreign matter into the bearing, or to prevent rust and corrosion effect. Methods: lubricating bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. Three, the installation of the bearings bearing installation is correct, affects the precision, life and performance. Therefore, design and assembly department for the installation of the bearing be fully studied. 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. Hope before the installation, just open the TPI bearing packaging in Taiwan. General grease lubrication, cleaning, not directly fill grease. Lubricating oil, ordinary also don't have to be clean, but, instrument using or high speed bearings, etc. , to be washed with clean oil, remove rust inhibitor) on the bearing. Remove the rust inhibitor of bearing, easy to rust, so cannot be placed. Also, has the bearing grease sealed, not directly use cleaning. Bearing installation method, because the bearing structure, cooperate, conditions vary, in general, as more as the axis of rotation, so the inner circle need interference fit. Cylindrical hole bearing, multi-purpose press pressure into, or multi-purpose hot charging method. Taper hole, installed directly on the taper shaft, or use the socket installation. Into the shell, clearance fit more commonly, outer ring had surplus quantity, usually with the pressure into the press and or have cooled after the installation of the shrink fit method. Use dry ice as coolant, shrink fit installation, the moisture in the air condenses on the surface of bearing. So, need a good rust prevention measures.
