Causes Of Abnormal Wear Of Bearings In Mine Wheels And Possible Consequences

The bearings are made of ordinary tapered roller bearings. Although the bearing capacity and axial thrust capability of this kind of bearing are high, the anti-seize property is very poor. In the process of use, once the mud is immersed, the bearing pipe will be blocked, the bearing lubrication will be damaged, and it will be damaged quickly.

After the inner ring of the wheel is worn, the mud water enters the bearing, causing a large area of corrosion of the inner and outer rings of the bearing. Mine wagon vibrates when driving on uneven tracks, causing additional impact loads and aggravating bearing wear.

The shaft and the bearing are generally matched by an interference fit. Although it is tight, the frequent action of the concentrated stress on the inner ring of the bearing causes the inner ring of the bearing to wear out and the bearing is scrapped. In severe cases, the wheel is dragged to death, causing a rollover accident.
