Prolonging the service life of the machine tool spindle bearing maintenance methods

For machine tool spindle bearing equipment preventive maintenance, and peripheral parts replacement operation were removed, thrust ball bearing to check to determine whether time bearing parts in turn can be used again and record the usage of good from bad. Carefully investigate and record the bearing and the appearance of being removed. In order to explore the residual amount of investigation and lubricant, after sampling, to clean the bearing well. Second check machine tool spindle bearing raceway surface, rolling surface and cooperate with the surface condition and wear conditions of cage with and without damage to watch the race and abnormal situation especially the running track. Judge bearing can use again, and the extent of the damage to considering the thrust ball bearings, machine performance, importance, and operation conditions, such as inspection period to decide later. Test results, if found damage and bearing abnormal situation, please according to the bearing damage phenomenon to find out the reason, to develop countermeasures. In addition, the test results, there are some defects, if the bearing can't use, need to replace new bearing. 1, machine tool spindle bearing cleaning removing of machine tool spindle bearing repair, first appearance record of machine tool spindle 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 cleaning of machine tool spindle bearing, coarse and fine fine cleaning cleaning, respectively in the container, put a metal mesh bottom first, make the machine tool spindle bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, will damage the machine tool spindle 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, in washing oil is to machine tool spindle bearing side spin, side carefully cleaned. In addition, the clean oil is always kept clean. 2, for the maintenance of machine tool spindle bearing in order to determine whether the spindle bearing is removed can use again, check after the wash machine tool spindle bearings, carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance, and presence of damage, abnormal about dimensional accuracy decline. Not separated type ball machine tool spindle bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Separation of tapered roller bearings and machine tools spindle bearings, rolling body, the outer ring raceway surface can be respectively. Large spindle bearing can't rotate with the hand, pay attention to check the rolling element and raceway and the appearance, such as, cage, guard the importance of machine tool spindle bearing high must check carefully. 3, machine tool spindle bearing is damaged to determine whether a standard can be used to judge, is to consider spindle bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. But, if you have the following defects can't use, must be replaced new bearing:
