The reducer is a power transmission mechanism that uses a gear speed converter to decelerate the number of revolutions of the motor to the required number of revolutions and obtain a mechanism with a large torque. In the current mechanisms for transmitting power and motion, the range of applications of the reduction gearbox is quite extensive.
It can be seen in almost every type of mechanical transmission system. Its application can be seen from the transmission of large power, to small loads, accurate angular transmission can be seen in the application of the reducer, and in industrial applications, the reducer has the function of deceleration and increased torque. Therefore, it is widely used in speed and torque conversion equipment.
1. The bearing position and bearing chamber of the reducer of the reducer of the reducer are repaired. Under the high-speed start of heavy-duty low-speed, heavy-duty high-speed and under the action of equipment vibration and radial impact, the metal occurs in the bearing chamber or bearing position. Fatigue, permanent deformation, the inner ring of the bearing and the shaft or bearing outer ring and the bearing chamber have a clearance fit, resulting in relative movement and wear.
Once this problem occurs, it will seriously affect the normal production of the equipment. If the bearing chamber of the reducer wears out, the replacement cost of the parts is high, and the manufacturing cycle is long. The general repair method is disassembling the post-welding machining or reaming and inserting the steel sleeve, which is time-consuming and laborious, and expensive. The excellent mechanical properties and good plasticity of the polymer materials make this problem properly solved, and greatly shorten the repair time of the equipment to ensure the huge economic value of the enterprise while ensuring the normal operation of the equipment.
The polymer composite repairing material is a composite material of a polymer, a metal or a ceramic ultrafine powder, a fiber or the like, and is compounded by a curing agent and a curing accelerator. Various materials complement each other in performance and produce synergistic effects, so that the overall performance of the composite material is superior to the original constituent materials. It has excellent bonding, mechanical properties, and chemical resistance. It is widely used in the mechanical wear, scratches, pits, cracks, leaks, casting sand holes, etc. of metal equipment and various chemical storage tanks. Chemical corrosion protection and repair of reaction tanks and pipelines.
The traditional methods of this kind of problem are difficult to repair and solve. The external repair is difficult to repair due to the limitation of the material and wear size of the parts. It is usually solved by replacing new parts, and the reducer is constantly improving, the parts are updated quickly, and the parts are occupied with huge funds. According to different equipments, different operating conditions, different wear conditions, the corresponding repair process can be used to repair quickly, simply and effectively. Especially due to the concession of polymer materials, 100% contact area is always maintained to avoid the occurrence of matching clearance. The repaired equipment even surpasses the new equipment, which fundamentally solves the cause of shaft wear.
In addition to the rapid repair of the bearing chamber of the reducer, the leakage of the static seal point of the reducer can also be treated with MEGAHUA polymer composite materials and technology to prevent leakage. The polymer composite material is leaked outside, saving time and effort. The effect is immediate, and its products have superior adhesion, oil resistance and 350% stretch to overcome the effects of vibration of the reducer. If the static sealing point leaks during the operation of the reducer, it can be blocked by the surface engineering technology oil surface emergency repair agent, so as to eliminate the oil leakage.
