Common burn failures in spherical roller bearing
Clicks:15417 Date:11-18
Spherical roller bearing is generally summarized as three points: poor lubrication of bearing; excessive load of imported bearings; poor bearing of shaft and bearing box is the cause of bearing burn; the following are the reasons why the bearing is burned in detail.
One of the causes of bearing burn is the poor lubrication of bearings, the use of irregular lubricants, or too much lubricant, too little, is not correct.
Two of the reasons for bearing burn are excessive load of bearing, too large bearing speed, small clearance of bearing, invasion of water or other foreign body.
The reason of bearing burn is the poor accuracy of the three shaft and bearing box and the large deflection of the shaft.
The three main causes of the bearing burn are the rolling wheel, rolling body and cage of the imported bearing, which are heated rapidly in the rotation until the color changes, soften, deposit and damage.
In the use of bearings, we should pay attention to installation, lubrication, clearance and other links to be as accurate as possible, in place, so as to reduce the bearing burns and prolong the service life of bearings.
The reason of bearing noise is complex, and the first is the abrasion of the inner and outer race surface of bearing. Because of this kind of wear, the relation between the bearing and the shell, the rolling bearing and the shaft is destroyed, the axis is deviated from the correct position, and the shaft produces abnormal sound at high speed. When the bearing is tired, its surface metal peeling, will also increase the bearing radial gap, resulting in abnormal sound. In addition, the bearing lubrication is insufficient, the formation of dry friction, as well as bearing broken, etc., will produce abnormal sound. When the bearing of HRB is loose, the cage will be loose and damaged, and the abnormal sound will be produced.
