സാധാരണ പ്രശ്നം:
Heat and oil leakage
In order to improve efficiency, worm gear reducers generally use non-ferrous metals as worm wheels, and worms use harder steel. Because it is a sliding friction drive, more heat will be generated during operation, which will cause differences in thermal expansion between the parts and seals of the reducer, thereby forming gaps in each mating surface, and the lubricating oil will become thinner due to the increase in temperature, which is easy to cause leakage . There are four main reasons for this situation. One is the unreasonable combination of materials; the second is the poor quality of the friction surface; the third is the incorrect choice of lubricant; the fourth is the poor assembly quality and use environment.
വേം ഗിയർ വസ്ത്രം
The worm wheel is generally made of tin bronze, and the matched worm material is hardened with 45 steel to HRC4555, or 40Cr hardened HRC5055, and then ground to a roughness of Ra0.8μm by a worm grinder. The reducer wears very slowly during normal operation, and some reducers can be used for more than 10 years. If the wear rate is fast, it is necessary to consider whether the selection is correct, whether it is overloaded, and the material, assembly quality or use environment of the worm gear.
ഗിയർ വസ്ത്രം
It usually occurs on the reducer installed vertically, mainly related to the amount of lubricant added and the oil variety. When installed vertically, it is easy to cause insufficient lubricating oil. When the reducer stops running, the transmission gear oil between the motor and the reducer is lost, and the gears cannot get the proper lubrication protection. When the reducer is started, the gears are not effectively lubricated, causing mechanical wear and even damage.

Worm bearing damage
When a failure occurs, even if the gearbox is well sealed, it is often found that the gear oil in the reducer is emulsified, and the bearings are rusted, corroded, and damaged. This is because the condensed water generated by the gear oil temperature rises and cools down after a period of operation of the reducer is mixed with water. Of course, it is also closely related to bearing quality and assembly process.

Ensure assembly quality
Some special tools can be purchased or made by yourself. When disassembling and installing reducer parts, try to avoid hitting with other tools such as hammers; when replacing gears and worm gears, try to use original parts and replace them in pairs; when assembling the output shaft, pay attention Tolerance matching; anti-sticking agent or red lead oil should be used to protect the hollow shaft to prevent wear, rust, or dirt on the mating area, which is difficult to disassemble during maintenance.
Lubricant selection
Helical gear-worm gear reducers generally use 220# gear oil. For reducers with heavy loads, frequent starts, and poor use environments, some lubricant additives can be used to make the gear oil still adhere to the gear surface when the reducer stops running , To form a protective film to prevent heavy load, low speed, high torque and direct contact between metals when starting. The additives contain seal ring regulator and anti-leakage agent to keep the seal ring soft and elastic and effectively reduce lubricating oil leakage.

Where the location permits, try not to use vertical installation. In vertical installation, the amount of lubricating oil added is much larger than that in horizontal installation, which may cause heat generation and oil leakage of the reducer.
ലൂബ്രിക്കേഷൻ പരിപാലനം
The reducer can be maintained according to the "five fixed" principle of lubrication work, so that every reducer has the person responsible for regular inspections, and it is found that the temperature rise is obvious, if the temperature exceeds 40 ℃ or the oil temperature exceeds 80 ℃, the quality of the oil is reduced or the oil If more copper powder and abnormal noise are found in the system, stop using it immediately, check and repair in time, troubleshoot, and replace the lubricant. When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated.
Repair method
To solve the problem of reducer wear and leakage, the traditional solution is repair welding or machining and repair after brush plating, but both have certain drawbacks: the thermal stress generated by the high temperature of repair welding cannot be completely eliminated, and it is easy to cause material damage and cause parts to bend. However, the electric brush plating is limited by the thickness of the coating, which is easy to peel off. The above two methods use metal to repair the metal, which cannot change the "hard-to-hard" coordination relationship. Under the combined action of various forces, it will still cause another Wear. Contemporary Western countries often use polymer composite repair methods for the above problems, which have super adhesion, excellent compressive strength and other comprehensive properties, and can be repaired on-site without disassembly and machining. Repairing with polymer materials is not affected by the thermal stress of repair welding, and the repair thickness is not limited. At the same time, the product has a retreat that the metal material does not have, which can absorb the shock and vibration of the equipment, avoid the possibility of re-wear, and greatly extend the equipment components The service life of the company saves a lot of downtime for enterprises and creates huge economic value.

1. The pressure in the fuel tank increases
In a closed reducer, each pair of gears meshing and friction will generate heat. According to Boyle Mario’s Law, as the operating time increases, the temperature in the reducer gradually rises, and the volume inside the reducer No change, so the pressure in the box will increase, and the lubricating oil in the box will be splashed on the inner wall of the reduction box. Due to the relatively strong oil permeability, under the pressure in the tank, where the seal is not tight, the oil will leak out from where.
2. Unreasonable structure design of reducer causes oil leakage
If the designed reducer has no ventilation cover, the reducer cannot achieve pressure equalization, causing the pressure in the box to become higher and higher, and oil leakage occurs.

3. Too much fuel
During the operation of the reducer, the oil pool is greatly agitated, and the lubricating oil is splashed everywhere in the machine. If the amount of oil is too much, a large amount of lubricating oil will accumulate on the shaft seal, joint surface, etc., causing leakage.
4. അനുചിതമായ അറ്റകുറ്റപ്പണി പ്രക്രിയ
During equipment maintenance, due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of the seal, and failure to replace the seal in time, oil leakage may also occur.
ചികിത്സാ പദ്ധതി
Use polymer composite materials to repair and control the oil leakage of the reducer. The polymer composite materials are made of polymer, metal or ceramic ultrafine powder, fiber, etc. as the base material, and are compounded under the action of curing agent and curing accelerator s material. Various materials complement each other in performance and produce a synergistic effect, so that the comprehensive performance of the composite material is better than the original composition material. With 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, etc. of metal equipment, as well as various chemical storage tanks , Chemical corrosion protection and repair of reaction tanks and pipelines. For the leakage of the static sealing point of the reducer, the macromolecule composite material and technology can be used to treat the leakage on the spot. There is no need to disassemble. The polymer composite material is externally treated for leakage, saving time and effort, and the effect is immediate. The product has superior adhesion. , Oil resistance and 350% stretch, overcoming the influence caused by the vibration of the reducer, and well solving the problems that have not been solved for many years. If the static sealing point of the reducer leaks oil during operation, the oil surface emergency repair agent of surface engineering technology can be used to stick it to eliminate the oil leakage.
