At the same time, the purchase of big motors at a discount will also encounter other faults, such as industrial motors in the long-term operation process, caused by stress often appear wear faults: such as reducer connectors transfer torque, flange surface connection
Uneven transmission torque caused by hole wear;Bearing position wear caused by motor shaft bearing damage;Wear between shaft heads, keyways, etc.After the occurrence of this kind of problems, the traditional methods are mainly repair welding or brush plating machining, but both of them have some disadvantages: the thermal stress generated by repair welding at high temperature cannot be completely eliminated, and it is easy to cause material damage and make parts bend or break;And brush plating by coating thickness limit, easy to flake, and the above two methods are metal repair metal, unable to change the "hard to hard" relationship, under the comprehensive action of all forces, will still cause wear again.At present, the main method of repairing metal is polymer composite material.Material has strong adhesion, excellent comprehensive properties such as compressive strength, the application of polymer composite materials to repair, no repair welding thermal stress, thickness of repair is not restricted, and the product of metal materials do not have rolled back, can absorb the impact of vibration equipment, avoid wear and tear, and prolong the service life of equipment parts, save a lot of downtime for the enterprise, creating huge economic value.
