How to test high temperature of TIMKEN bearings running accuracy? below, assembled and running accuracy of rolling bearings of detection, we give the two methods, the user can choose with the actual situation.
Spindle Assembly after the need to check the running accuracy of the bearing. The most commonly used method is a method of machine tool spindle bearings check. Appropriate measurements on the surface of shaft in the radial and axial runout. However practice shows the ovality and eccentricity of the spindle on the surface to measure are usually very large, it is difficult to get inside of eccentricity of bearing or spindle.
Detection of high temperature of TIMKEN bearings running accuracy, in a better way, is a precise grinding of welded ball to mounted on swivel joints on the block. Micro indicator or similar meter with equal precision measurement contacts mounted on a ball. Ball joint in the shaft head, its fixation should be allowed to gently hit ball after ball to moves in perpendicular to the main axis. Minimum reading is obtained when the spindle is rotated without load radial precision spindle bearings. In a horizontal position the indicator reading is on the ball spindle axial runout values. If you are turning the inner ring raceway deviation from the centerline of the shaft, then beating twice times the eccentricity of the shaft.
Use effective and accurate method for detecting high temperature of TIMKEN bearings running accuracy in order to accurately test the running accuracy of the bearing, in order to effectively improve the running accuracy of the bearing, increase the rigidity of bearing's combination, reduce the axial vibration and noise when in operation, improve the service life of rolling bearings.
Demolition high temperature maintenance of TIMKEN bearings, bearing the appearance of first record, confirm that the residual amount of lubricant, sampled after checking the lubricant, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Removed bearing wash, heavy wash and light cleaning, placed in a container, placed on the metal mesh bottom, bearing no direct contact with the dirt container. Coarse cleaning, if the bearings rotate with dirt, scroll bars can damage the bearing surfaces, should be noted. In crude oil cleaning, use a brush to grease removal, adhesive, after largely clean, fine wash.
Sperm washing, where cleaning oil side bearings is the rotation, careful cleaning. In addition, cleaning oils to keep clean.
Inspection and repair of high temperature of TIMKEN bearings, and judgment: in order to determine whether removing bearings can be used to check after you wash the bearing. Checks on Raceway surface, scroll, status of the mating surfaces, wear of the cage and rolling bearing clearance increased and decreased accuracy of injury has nothing to do with size, the exception. Non-separation of small ball bearings, the inner ring with one hand supporting level, rotate the outer ring to confirm fluency.
