Many equipment managers in enterprises have encountered wear and tear in the bearing chamber of gearboxes. Minor wear may not directly affect normal use, but if not repaired in a timely manner and used for a long time, the wear will become more severe, thereby affecting the normal production of the enterprise. Next, we will use a case study to see how to timely and effectively repair the wear problem of the gearbox bearing chamber.
During maintenance, a paper company discovered that the bearing chamber of the dryer gearbox was worn unevenly, with severe localized wear reaching a depth of about 10mm and an average of about 3mm. The relevant equipment parameters are as follows: bearing model 22313, bearing and shaft are fitted with retraction sleeves, and the speed is 745r/min. When the company encountered serious wear and tear in the gearbox bearing chamber, it chose Sorel carbon nano polymer material technology for online repair. Before understanding this technology, let's first appreciate the on-site picture of repairing the wear of the gearbox bearing chamber using this technique.
There are many repair techniques for the wear of gearbox bearing chambers, why did the company choose Sorel carbon nano polymer material technology? What are the advantages of this technology?
1. This technology can achieve online repair of gearbox bearing chamber wear without the need for extensive disassembly of equipment. Only the repair parts need to be disassembled, which can not only reduce the labor intensity of workers and safety factors during construction, but also shorten the downtime of enterprises and reduce the losses caused by it;
2. This technology does not generate high temperatures during the online repair process, effectively protecting the equipment from damage, and is not limited by the unilateral wear of the bearing chamber during the repair process;
3. The comprehensive mechanical properties of the repair material are superior to those of metals, with good yielding properties and no metal fatigue wear characteristics or plastic deformation. Therefore, there will be no fatigue wear or fracture during long-term use, ensuring that there will be no gaps between the static mating surfaces of the equipment due to fatigue wear during long-term operation;
4. Over the years, we have accumulated rich experience and summarized nearly a thousand repair solutions for equipment. We have provided solutions and maintenance services for many industries and enterprises such as steel/metallurgy, cement, papermaking, chemical, power, shipbuilding, and machinery manufacturing.
