The first type of failure: When the inner and outer rings of the bearing and the rolling elements are seriously damaged, the bearing is seriously damaged and needs to be replaced. (1) The concentricity correction value is not more than 0.015mm, which prevents the high-speed operation noise from increasing, vibration and heat during eccentricity, and shortens the service life of the motor; (2) When the motor journal is <40mm, it is advisable to use 6-8 equal parts of line surfacing, and the >40mm journal should be fully surfacing. This is determined by the amount of force transmitted by the shaft at the output power. Regardless of the type of surfacing, it is necessary to pay attention to the use of intermittent strips, symmetrical welding, to prevent excessive local welding stress and excessive first question, resulting in increased concentricity of the shaft. (3) When turning the lathe, the turning roughness of the motor shaft below 11KW is controlled to about 3.2. After the 11KW motor shaft and the end cap hole are turned, it is better to use the grinding machine for finishing to ensure the quality.

The second type of failure: When the bearing of the flour machine is separated from the shaft, the gap between the rotor and the shaft is reset by the high temperature resistant 502 adhesive. The injection part should be placed vertically and the action should be rapid. After filling at both ends, it is re-irrigated with 40% brine and placed for a few days before assembly.
The third type of failure: When the bearing is worn, some can be repaired by means of a welding car. For example, when the bearing runs inside and outside the ring, the journal and the inner hole of the end cap are welded by electric welding, and then processed into a required size by a lathe. The preheating shaft and the inner hole of the end cover are preheated before welding. At the end of the welding, it is buried in the dry lime powder and slowly cooled to control the quenching and brittleness. When repairing with electric welding, it is necessary to pay attention to:
