NSK bearing installation and maintenance - bearing knowledge

1, NSK bearing maintenance: for as long as possible with NSK bearing in good condition to maintain original performance, 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. In the operation maintenance item, NSK bearings with the rotation of the sound, vibration, temperature, the state of the lubricants and so on. NSK bearing NSK bearing 2, maintenance: cleaning: removing NSK bearings under repair, the appearance of the first record NSK bearings, confirm the residual stock of lubricant, sampling inspection with lubricant, wash the NSK bearings. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the NSK bearings cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, NSK bearing not make direct contact with dirt from the container. Coarse when cleaning, if rotating the NSK bearings with dirt, NSK bearings can damage the 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, NSK bearings in the cleaning of oil side spin, side carefully cleaned. In addition, the clean oil is always kept clean. The overhaul and judgment: 3, NSK bearings in order to judge whether the NSK bearings of the removed can use, check NSK bearings in clean water after. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of NSK bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation NSK bearings, small ball, the inner ring with one hand support levels, rotate the outer ring confirm whether smooth. Tapered roller bearing NSK bearing separation form, can be respectively of the rolling elements, the outer ring raceway surface inspection. Large bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage and guard surface appearance, the more the higher the importance of NSK bearings must be careful check. 1, work together as much as possible through the axis of the NSK bearings, which requires the screws evenly symmetry and smooth, by spherical or parallel to the axis force application. 2, the size of the wire should be smooth and uniform, unfavorable impact, this request can use hydraulic or use steady pull or pressure tool, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. It is best to use copper or copper hammer hammer. 3, avoid by applying pressure roller, which requires the inner ring (installation Axial circle) When applying pressure through the inner ring and outer ring installation) Through the outer power works. 4, the extent of the drag force continued to be, for example when installing NSK bearing NSK bearing fit in to the correct position to stop work, guarantee the ring ( Washers) The end face of landing on a hole or shaft shoulder end, neither packed too tight, nor does not reach the designated position.
