Problems solved by technology

The surface of the collector ring is seriously damaged, and some collector rings even have arc burnt deep pits on the surface of the collector ring. When the brush is running, it jumps a lot, which affects the normal operation of the motor.
Normal repair needs to disassemble the motor as a whole, then disassemble it, and pull out the rotor to repair the collector ring. This method takes a long time to repair and brings losses to the company's profits.

Embodiment Construction

[0011] During the running process of the motor, many potholes are formed on the surface of the collector ring due to the action of the electric arc. The irregular deep pits cause the brush jumping during the motor operation. Online repair, the specific steps are:

[0012] ① Fix two insulating baffles 1 perpendicular to the horizontal plane on the outer side of the collector ring 2 to be repaired, and the bottom of the two insulating baffles is a sealed structure; ensure that the cuttings do not come into contact with any conductor;

[0013] ② Open a hole on the insulation baffle 1, the position of the hole corresponds to the collector ring 2 to be repaired, and the gap between the opening of the insulation baffle 1 and the two sides of the collector ring 2 is ≤1mm; the collector ring 2 The distance b=2-4mm to expose the insulating baffle 1;

[0014] ③Use a grinder to grind the surface of the collector ring through the hole on the insulating baffle, polish the surface of the c...

Abstract

The invention relates to a method for repairing a collecting ring on line. In the method, the collecting ring is repaired on line under the condition that a motor is electrically operated, the collecting ring is driven to rotate by the power of the motor, and insulation protection treatment is carried out on the outsides of the collecting ring and a tool. The linear speed of the collecting ring is controlled to between 2 and 6 meters per second and the penetration of the tool is controlled to between 0.05 and 0.30mm. Compared with the prior art, the method has the advantage that the method repairs the collecting ring on line under the condition that the motor is electrically operated, shortens repair period, and improves work efficiency and enterprise benefit.

Description

technical field [0001] The invention relates to a method for repairing electromechanical equipment, in particular to an online method for repairing slip rings. Background technique [0002] During the operation of AC motors in the production process, the collector rings have different degrees of wear and arc burns. The surface of the collector ring is seriously damaged. Some collector rings even have deep pits caused by arc burns. Normal repair needs to disassemble the motor as a whole, then disassemble it, and pull out the rotor to repair the collector ring. This method has a long repair period and brings losses to the company's benefits. Contents of the invention [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a method for on-line repairing of the slip ring, the method can carry out online repair of the slip ring of the AC motor running with electricity, the operation is convenient, and the repair peri...
