What Should Be Done If The Bearing Of DC Traction Motor Is Damaged

First of all, the grease in the bearing raceway has been intensively stirred for a long time. The torque of the bearing is large and the temperature is high, which leads to imbalance. The further increase of the temperature will lead to a series of vicious cycles, Battery Locomotive and finally the inner, outer and rolling elements of the bearing are stuck and unable to work.

Secondly, the common fault symptoms of bearings are loose rivets of cage, fracture or eccentric wear of peripheral retaining edge, rolling property, peeling off of raceway, burning mark, scratch, crack, askew wear or increase of radial clearance, loosening or seizing of inner ring, electric erosion of shaft current and deterioration of lubricating grease, loosening and deformation of bearing oil tank, etc.

Therefore, the vibration and noise are often increased, resulting in the collision and wear of pinion, damage of winding insulation, fracture of connecting wire,Battery Locomotive poor commutation, grounding or ring fire, and even rotor seizure, which is difficult to rotate and shaft cracking.

Finally, the fit between the bearing and the shaft is too loose or too tight. If it is too loose, insert the sleeve on the bearing. If it is too tight, rework the shaft to the standard size.

he above problems and related solutions are the analysis brought to us. When encountering the above faults, we can't solve them blindly. First, we need to understand the causes of the faults. The key to solve the problems is to use the corresponding measures. To learn more about electric locomotive, please click the website link to enter the relevant content introduction
