Reducer is a kind of power transmission mechanism, which uses the speed converter of gear to reduce the number of revolutions of motor to the desired number of revolutions, and get a larger torque. In the current mechanism used to transmit power and motion, the application range of reducer is quite wide.

It can be seen in almost all kinds of mechanical transmission system. Its application can be seen from large power transmission to small load and accurate angle transmission. In industrial application, the reducer has the function of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.

Repair of the wear of the bearing chamber of the reducer. Under the heavy load and low speed, heavy load and high speed and high torque starting, as well as under the effect of equipment vibration and radial impact, metal fatigue occurs in the bearing chamber or bearing chamber, resulting in permanent deformation. The clearance between the bearing inner ring and the shaft or between the bearing outer ring and the bearing chamber results in relative motion wear.

Once this problem occurs, it will seriously affect the normal production of the equipment. If the bearing chamber of reducer is worn, the replacement cost of components is high and the manufacturing cycle is long. The general repair method is machining after disassembly and repair welding or reaming and inlaying steel sleeve, which is time-consuming and expensive. The excellent mechanical properties and good plasticity of polymer materials make the problem properly solved, greatly shorten the repair time of the equipment under the condition of ensuring the normal operation of the equipment, and create huge economic value for the enterprise.

Polymer composite repair materials are based on polymer, metal or ceramic ultrafine powder and fiber, which are compounded under the action of curing agent and curing accelerator. Various materials learn from each other in performance and produce synergistic effect, which makes the comprehensive performance of the composite better than that of the raw materials. It has strong adhesion, mechanical properties and chemical corrosion resistance, so it is widely used in the repair of mechanical wear, scratch, pit, crack, leakage and casting sand hole of metal equipment, as well as the chemical corrosion protection and repair of various chemical tanks, reaction tanks and pipelines.

This kind of problem is difficult to be solved by traditional methods on site, and it is difficult to be repaired by outsourcing repair due to the limitation of component material and wear size. It is usually solved by replacing new components, and the reducer is constantly improving, the parts are updated quickly, and the spare parts storage takes up a huge amount of money. According to different equipment, different operation status and different wear conditions, the corresponding repair process can be adopted to repair quickly, simply and effectively. Especially due to the concession of polymer materials, the 100% contact area is always maintained to avoid the generation of fit clearance, so that the service life of the repaired equipment even exceeds that of the new equipment, which fundamentally solves the causes of shaft wear.

In addition to the quick repair of the wear and tear of the bearing chamber of the reducer, the leakage of the static sealing point of the reducer can also be treated on site with meijiahua polymer composite materials and technology without disassembly. The polymer composite materials can be used to treat the leakage externally, saving time and labor, and the effect is immediate. The products have superior adhesion, oil resistance and 350% tensile strength, To overcome the influence of vibration of reducer. If there is oil leakage at the static sealing point during the operation of the reducer, the oil surface emergency repair agent of surface engineering technology can be used to plug, so as to eliminate the oil leakage.
