Some operators have little experience in identifying rolling bearings; they only need to see the rolling bearings continue to operate without significant damage; this has led to serious problems. Some people just need to remove the rolling bearings; replace them without checking them; sometimes they can Continuously used bearings have also been replaced. The skill of the rolling bearing should be viewed on a dedicated viewer; some data can also be measured with a dial indicator. But for the usual machine; when these conditions are not available; You can use the experience method to view it roughly. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
(1) Investigation method. Investigate the rolling bearing with the naked eye; the raceway in the table should have no detachment marks and severe wear; and it should be in the shape of a circular groove. All the tumbling surface should be free from mottle, crack and peeling. The cage should not Loose, unbroken, not worn; the gap with the roll is not too big.
(2) Hand feeling method. The gap between the inner race and the roll of the normal bearing is 0. 005 to 0. 010 mm. For the rolling bearing that has been used for one period; when the inner race is pinched with fingers to perform axial shaking There should be no significant squeaking noise.
(3) Transformation method. Hold the inner race of the bearing with one hand; change the outer race with the Other hand; the bearing should be sensitive to change; and the radial sway should not be felt.
When viewing; should combine the above three methods of experience; in order to facilitate the correct judgment of the skill of the rolling bearing. About tapered roller bearings; should also investigate whether the roll can be located in the center of the outer ring; if there is before Move; should not exceed 1. 5 mm.
