Author: admin Time: 2019-04-26 14:44

Information of Xi'an Xima Motor Group Co., Ltd .: We know that during the use of motor shafts, due to environmental and use problems, some shaft wear will occur over time. Can these wear conditions be repaired? The following Xi'an Xima Motor Group Co., Ltd. will take you to specific analysis based on specific situations:
First we need to look at the specific damage location of the lower shaft:
First, motor shaft bearing position wear, motor bearing room wear, shaft head keyway wear.
Traditional repair methods: mainly brush plating, spray coating, surfacing or replacement. Brush plating is easy to delaminate and the replacement cost is high, so it is difficult to solve the problem.
Wear of 380Kw motor shaft bearings
After the motor shaft bearing is damaged, the bearing position is worn. After the problem occurs, repair or repair after welding or brush plating according to the traditional method. However, the thermal stress caused by the high temperature of repair welding cannot be completely eliminated, and it is prone to bending or fracture; brush plating is limited by the thickness of the coating, and it is easy to peel off; and the above methods all use metal to repair the metal, and cannot change the "hard to hard" cooperation relationship Under the combined effect of various forces, it will still cause wear and tear again.
Three, 900Kw motor bearing position, bearing room wear
During the long-term operation of the motor, due to various factors, the wear of the bearing room is very common. After the problem occurs, the traditional method cannot be solved on the spot and must be repaired or replaced by external partners. Changing the "hard-to-hard" cooperation relationship will still cause wear and tear under the combined effect of various forces.
Fourth, 90Kw motor bearing room wear
During the long-term operation of the motor, due to various factors, the wear of the bearing room is very common. After the problem occurs, the traditional method cannot be solved on site and must be replaced by scrap.

From the above points, the problem of motor shaft wear is difficult to repair by traditional methods, and most of them may need to be replaced. However, this method has high cost and long cycle. The quality of the motor after repair is not as good as before. Chance of damage. According to our experience, it is recommended to replace the motor directly if the shaft is severely worn!
