How to detect TIMKEN whether the precision of the rolling bearing maintenance in place

How to detect running accuracy TIMKEN bearings? Below, the assembled roller bearing running accuracy of detection, we present two methods, the user can with the actual situation to choose. Need to check after the spindle assembly good running accuracy TIMKEN bearings. The most commonly used method is machine tool bearing spindle examination method. On the shaft head of the surface of the appropriate measurement of radial and axial runout. But practice shows that the spindle measured on the surface of the ovality and eccentricity are usually very big, difficult to get the real rolling bearing or spindle eccentricity. Running accuracy detection TIMKEN bearing and a better way, is a through precise grinding ball welded to the loading on the joint of the shaft head. Will trace indicator or similar instrument have the same precision of measuring contact loaded on the ball. Fixed ball joint fixed on the shaft head, the fixed way should be made to tapping the ball after the ball can move perpendicular to the main axis. Spindle rotates to obtain the minimum reading is no-load radial precision of the spindle bearing. Horizontal position indicator in the sphere of reading is the main shaft axial runout of value. If you are rotating inner ring raceway deviation from the centerline of shaft, the shaft beating will be twice the eccentricity. Running accuracy by using effective accurate detection of TIMKEN bearing method, can accurately test the bearing running accuracy, can effectively improve the bearing rotating accuracy, increase the combination of bearing rigidity, reduce the shaft in the operation of the vibration and noise, improve the service life of rolling bearing. 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 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 rolling 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.
