Presses, general equipment in industrial production. The main shaft of the press is the core part of the press. The repair of the position of the main shaft bearing has always been one of the hot issues that the company is very concerned about. Regarding the repair process of the spindle, new technologies from the traditional to the modern have always been the focus of attention.
In the coffee grounds processing workshop, the operation of the spindle of the 2# press was abnormal. After the shutdown inspection, it was found that the inlet of the equipment entered the steel pipe, and the interaction between the main shaft blades and the filter wall caused a deep defect in the broken mesh wall, resulting in the entire main shaft. The axial displacement is formed. Due to the large torque force, the axial force generated by the action of the main shaft spiral blade is also large, so that the thrust bearing on the transmission side is crushed and crushed, and the main shaft and the main shaft are severely worn.
After a problem with the equipment, organize the tissue to disassemble and inspect the transmission side support components and the motor. After disassembly, it was found that the outer ring of the thrust bearing in the bearing housing was completely broken, and the broken bearing also caused serious damage to the bearing housing and could not be used. After disassembling the bearing, it was found that the bearing position was severely worn and could not be recovered. Since the equipment is imported from Germany, there is no such large imported spare parts and it can only be repaired. The company contacts external employees to understand the repair method. No company can use it to fix traditional technology, and it can't guarantee its effect.
Later, using Solei industrial field service technology, there is a complete range of maintenance solutions and on-site repair procedures for bearing wear. It takes into account the different equipment on site, different bearing fits, etc., taking into account the concentricity and journal tolerances after repair. After the factors such as size and surface roughness, the mature repair process suitable for the on-site working environment is adopted to achieve the purpose of rapid repair on site.
Acid nanopolymer pain site repair process:
1 surface treatment: baking oil, grinding, cleaning, to achieve the purpose of rough, clean and dry shaft repair;
2 mixing the Sole carbon nano-polymer material and then uniformly coating the surface of the shaft;
3 use the on-site maintenance process for rapid prototyping;
4 kinds of polymer materials are naturally cured;
5 clean the surface and complete the bearing repair work;
6 bearing assembly is done according to different assembly requirements, bearings and other components can be hot packaged.
