Problems solved by technology

When the reducer is working in the underground, the working conditions in the underground are quite harsh, the end cover of the reducer is easily damaged by collision and extrusion, and the end cover of the reducer cannot be used after being worn
For the existing situation, after the end cover of the reducer is worn, it cannot be repaired, and it is generally scrapped, thus increasing the production cost and labor cost

Embodiment 1

[0046] A method for repairing wear of an end cover of a reducer, the specific steps are:

[0047] (1) Clean up:

[0048] a Remove the worn end cover of the reducer, and clean the resin glue and hard objects on the surface;

[0049] b After cleaning the surface resin glue and hard objects, use cleaning agent and thinner to clean the surface oil and paint;

[0050] c After cleaning the oil and paint on the surface, pre-treat the position to be repaired, roughen the position to be repaired, so that the surface has a certain roughness, which is convenient for enhancing the mechanical bite force during subsequent coating;

[0051] d Wipe the roughened surface clean with acetone, and then dry it with a hot air blower;

[0052] (2) Smudge:

[0053] Stir the polymer composite material and the curing agent, the polymer composite material and the curing agent are fused with each other, and then apply the fused material mixture evenly to the position to be repaired on the end cover of...

Abstract

The invention discloses an abrasion repair method for speed reducer end covers. The abrasion repair method is used for repairing the abraded speed reducer end covers, the production cost is reduced, machining is convenient, a special organic material is generated after a mixed material is cured and heated and bonded with epoxy ring molecules, an excellent metal binding agent is formed, the intermolecular bonding force is improved, overall performance of the surface of a material mixture is improved accordingly, the adhesive force of the speed reducer end covers and the mixed material is enhanced, and reliability is improved. In addition, by means of a machining process, the maintenance time can be shortened, maintenance can be conducted at a working site, and the speed reducer end covers can be quickly installed and put into use.

Description

technical field [0001] The invention relates to the field of wear and repair of the end cover of the reducer, in particular to a method for repairing the wear of the end cover of the reducer. Background technique [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery. When the reducer is working in the underground, the working conditions in the underground are quite bad. The end cover of the reducer is easily damaged by collision and extrusion, and the end cover of the reducer cannot be used after being worn. For the existing situation, after the end cover of the reducer is worn, it cannot be repaired, and it is generally scrapped, thus increasing the production cost and labor cost. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a method for repairing the wear of the end cover of the ...
