How to repair rotor shaft wear
The motor rotor shaft is a rotating part of the motor and a conversion device that realizes electrical energy, mechanical energy, electrical energy and electrical energy. The rotor shaft is often damaged by wear and impact during work and maintenance. As the central part of the motor structure, the rotor shaft is responsible for the dimensional coordination and installation of the various components of the motor. If it can be repaired in time, the motor rotor shaft can continue to be used after wear, saving part of the cost of replacing equipment.
In fact, shaft wear is a common problem of all mechanical equipment. As long as there is no problem with other parts, repair the wear as soon as possible, and the equipment can continue to be used. There are many reasons for the wear of the motor rotor shaft. The manifestations of wear are mainly divided into abrasive wear, fatigue wear, bond wear, fretting wear, etc. Although the metal has high hardness, it is poor in reversion (it does not recover even when deformed), poor in impact resistance, poor in fatigue resistance, and easily causes wear of the bearing position and the bearing chamber.
In view of these situations, the Soller carbon nano-polymer material can be used for coating repair, and it is simple and fast in the case of artificial repair. The material is a new and reliable equipment maintenance and remanufacturing materials, with physical properties, chemical corrosion properties, excellent mechanical properties, high temperature performance, at the same time has ductility and retractability, to meet the requirements of equipment to withstand various impact, Can absorb the impact and vibration of the equipment in operation.
Repair the wear of Soler carbon nano-polymer material on the rotor shaft of the motor; carry out surface degreasing treatment; coarsening treatment; prepare and coat carbon nano-polymer material, and scrape the knife edge according to the standard; material curing; detect the wear size based on the standard size of the journal without wear; heat curing for 1-2 hours to ensure that the material is completely cured; check the repair surface and heat curing to complete the repair.
Use oxygen acetylene to bake oil on the worn part of the motor rotor shaft; Turn the table on the motor rotor shaft to find the right; Rough turning treatment is carried out on the repaired part; Use anhydrous ethanol for cleaning; Blend Soley carbon nano-polymer material in proportion to be uniform and no color difference, apply the uniform material to the part to be repaired, and wait for the material to cure; After the material is cured, turn to size.
