Abstract:
In view of the problem that the size of rotor bearings mating surface exceeds the tolerance and affects the bearing assembly, combined with the characteristics of wax injection in the inner cavity of the parts, complicated product process and long processing period, it is proposed to use the brush plating technology to repair the size of bearings mating surface.Based on the analysis of the feasibility, reliability and technical key points and difficulties of the brush plating process parameters, the process parameters and tooling of this type of rotor are designed and optimized.After brush plating of the rotor bearing matching surface at room temperature, the copper coating thickness of the rotor bearing matching surface is satisfied.In addition, the coating state of the rotor is good in the belt speed test, and the feasibility of the process technology is verified by water test.
