Repair of Bearing Chamber Wear in Extruder Reducer
The reducer is an extremely important component in extruder equipment. Once the spindle bearing position is worn or the housing bearing chamber is worn, it will have a serious impact on the operation of the entire equipment and prevent normal production. Next, let's learn about several common repair methods for bearing chamber wear in gearboxes.
There are several repair solutions for the wear of the bearing chamber of the reducer, including: (1) on-site electric brush plating process, (2) welding machine processing repair, and (3) Sorel carbon nano polymer material repair. Let me explain to you in detail the advantages and disadvantages of various repair techniques.
1. Electric brush plating repair process
Its advantage is that it can achieve online repair, but its disadvantages are very obvious. The brush plating process is limited by the amount of wear on the brush plating coating. Generally, the brush plating thickness of the brush plating coating is less than 0.2mm. When the wear amount is greater than 0.2mm, the brush plating efficiency will decrease exponentially, and when the brush plating layer is too thick, it is easy for the brush plating layer to fall off during use, shortening the service life.
2. Welding machine processing and repair technology
Welding machine processing is a common method in traditional repair techniques, characterized by high repair accuracy. Its disadvantage is that it is prone to stress concentration during the repair process of small components, and special welding processes must be used for special materials; For the wear problem of the gearbox bearing chamber, it is impossible to repair it online. Disassembly and transportation will greatly increase the repair cost and repair cycle, and the requirements for machining equipment are extremely high. The overall cost-effectiveness is low, which greatly affects the normal production of the enterprise and increases maintenance costs.
3. Sorel Carbon Nanopolymer Material Repair Technology
Carbon nanopolymer materials are two-component composite materials generated by polymerization techniques of nano inorganic materials, carbon nanotubes, and other materials. This material has strong adhesive strength, good compressive performance, and comprehensive mechanical properties such as elastic deformation that metals do not possess. It can achieve online repair of wear problems in the bearing chamber of reducers with high repair efficiency, without the need for extensive disassembly of equipment. Generally, repairs can be completed in just a few hours. Not only that, there will be no high temperature generated during the online repair process, which effectively protects the equipment body from damage and prevents metal fatigue wear during use. Under the premise of normal maintenance and upkeep of the equipment, the service life of the repaired components is even higher than that of the new components.
