Oil leakage of gear reducer! SAINEER Teach you how to fix it

Reducer is an independent closed transmission mechanism between motor and working machine. It is used to reduce the speed and increase the torque accordingly. It is an important part of coal mine machinery and equipment. In actual production, the oil leakage of mine reducer is easy to occur in different degrees due to poor working environment, heavy load and frequent start-up of equipment, which not only causes energy waste and environmental pollution, but also causes bearing heating, dry grinding, gear gluing, pitting and other phenomena due to lack of lubricating oil in the box, and finally reduces. The service life of speeder will lead to equipment accident when it is serious.            

1. In the enclosed space of the reducer, every pair of gears in the gear reducer will generate great heat when meshing. With the increasing of working time, the temperature in the reducer will gradually increase, while the internal volume of the reducer box is fixed. Thus, the pressure in the reducer will become larger and larger, and the reducer The oil permeability inside the tank is relatively strong. Where the seal is not tight, the oil will permeate from where.           

2. The second reason may be that the unreasonable structure design of the reducer causes oil leakage of the gear reducer. For example, when a certain type of reducer is designed without a ventilation hood, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box, then oil leakage will occur.            

3. When the cover of the reducer is operated carelessly, the harmfulness of the oil leakage of the reducer is not recognized. The structure design of the reducer is very good, resulting in oil leakage.           

In the selection of gear reducer, the quality of oil seal and its structure are the key points for the selection of gear reducer. Above is a brief introduction to the role of oil seal of reducer, and also from other aspects to understand.            

The gear reducer adopts polymer composite material to repair and control the oil leakage of the reducer. The polymer composite material is composed of polymer, metal or ceramic ultrafine powder, fiber and other materials, under the action of curing agent and curing accelerator. All kinds of materials complement each other in performance and produce synergistic effect, so that the comprehensive properties of composite materials are better than those of original materials. Because of its strong adhesion, mechanical properties and chemical corrosion resistance, it is widely used in the repair of mechanical wear, scratches, pits, cracks, leakage, casting sand holes of metal equipment, as well as the chemical corrosion protection and repair of various chemical storage tanks, reaction tanks and pipelines. For the leakage of static sealing point of gear reducer, Megawa polymer composite material and technology can be used to control the leakage on site without disassembly. The polymer composite material can control the leakage on the outside, save time and effort, and achieve immediate results. Its products have superior adhesion, oil resistance and 350% tensile strength, and overcome the vibration of the reducer. As a result, it has solved the problems that cannot be solved for many years for enterprises. If the oil leakage occurs at the static sealing point of the reducer in operation, the oil surface emergency repair agent of surface engineering technology can be used to plug the oil leakage, so as to achieve the purpose of eliminating the oil leakage.
