The rotor shaft is the core component of the motor structure. Repairing the motor is a very important task, and laser cladding technology perfectly completes this repair work. The maintenance quality of the rotor shaft is in compliance with the technical standards for maintenance, so that the maintenance of the entire motor meets the standards. Compared with surfacing, spray coating, electroplating and vapor deposition, spindle repair cladding has the characteristics of less dilution, dense structure, good combination of coating and substrate, suitable for cladding materials, large particle size and content changes, etc. The application prospect of overlay technology is very broad. Repair Name: Motor Rotor Shaft (Electric Bus Motor Rotor Shaft) Repair material: 45 steel, 35CrNoMo
Basic situation: The long-term overload of the bus causes the motor to work overload. During the operation of the electric bus, the electric motor suddenly brakes the shaft and the end cap instantly locks to form a non-mechanical cooperative rotation, which causes the product to wear. The repair period is 3-4 months.
Repair requirements
The laser cladding technology is used to replace the traditional electroplating process. The coaxiality error of the bearing chamber end cover stoppage does not exceed 0.02mm in diameter, and the cylindricalness of the bearing chamber does not exceed 0.006mm. Surface roughness Ra = 1.6, end face chamfer C1. After the repair, there should be no pores, slag inclusion, and fusion phenomenon.
