IKO regularity of tapered roller bearing failure adjustment method

Removed for bearings have to be serious for maintenance and cleaning, carefully examine IKO bearing raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of taper roller bearing clearance, and presence of dimensional precision falling damage. Type for the 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. However, large bearing can't rotate with the hand, so should pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of tapered roller bearings, the higher the check carefully. So how to maintenance and cleaning after judgment is removed IKO bearings can be used again? There is need to consider the bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. Late show bearing fault feature to severe fault ( For bearing damage, such as holding shaft commonly, burns, sand spallation, raceway, wear beads, etc. ) Most of time not more than a week, the bigger the equipment capacity, the faster the speed, the shorter the time interval. Therefore, in the actual bearing fault diagnosis, once found late fault characteristics, should be decisive judgment IKO bearing fault, arrange inspection as soon as possible. 1 taper roller bearings, low noise, the installation and adjustment of also can follow the long life of tapered roller bearing grouping method, makes the interference fit the size is consistent, bearing clearance is relatively consistent, and hope to cooperate with interference within may take smaller values, to ensure the deformation of bearing raceway is small, and rolling body caused by noise is smaller. 2, clearance on the relationship between the noise is very large, ideally when imported bearing in running state, the highest temperature clearance value is zero. Judgment methods of clearance is too large, stationary state made shaft axial displacement, the extent of the reciprocating is bigger, the big and heavy turbidity of a noise during operation. 3, if the hate sharp whistlers, then tapered roller bearing preload is too big, preloaded, bearing a large prestressing degree should have to relax. If the clearance is too large, can make the two IKO bearing ring along the axial relative offset slightly: both reduced clearance, and increase the axial rigidity, bearing noise can be reduced. 4, rolling body around would not bite into the no-load area or channeling, that will not only increase the noise can also cause wear and tear, and the small clearance and large axial stiffness can eliminate the phenomenon. But cannot too small clearance, lest cause high temperature and shorten the life. 5, sometimes due to host large working temperature range, or shaft with a hole the size of the discreteness is very big, can't get a setting on a proper clearance, in this case, a can of tapered roller bearing outer ring by using elastic constant pressure preload. The causes of the residual magnetic bearing, should be how to eliminate? IKO bearing parts of magnetic clamping adopted in production process and welding, riveting process, make the bearing parts produces magnetic field, but in the subsequent demagnetization process refund or improper demagnetization of the residual magnetic leakage phenomenon. So be demagnetization before assembly parts, the residual magnetic strength should be lower than bearing the finished product inspection standards. Especially if there are any residual magnetic roller, is more difficult to return after the assembly, often subject to repeated many times to return a net. There are many types of fatigue, for IKO bearings mainly refers to the contact fatigue. Tapered roller bearing ring and roller surface in contact stress under the action of repeated, the rolling surface of the metal from the metal substrate dot or flake peeling off phenomenon called fatigue spalling. Pitting corrosion is caused by material fatigue a fatigue phenomenon, but the shape size is very small, pitting extension will form after fatigue spalling.
