FAQ editing
Fever and oil leakage
In order to improve efficiency, helical gearbox generally use non-ferrous metals for helical gears, while helicals use harder steel. Because it is a sliding friction transmission, more heat is generated during operation, which causes a difference in thermal expansion between the various parts of the gearbox and the seal, thereby forming a gap in each mating surface, and the lubricating oil is thinned due to an increase in temperature, which is liable to cause leakage. . There are four main reasons for this situation. One is that the material is not properly matched; the other is the poor quality of the surface of the friction surface; the third is that the amount of lubricant added is not correct; the fourth is the poor quality of assembly and use.

Coaxial helical inline gearboxCoaxial helical inline gearbox

The helical gear is generally made of tin bronze, and the paired helical material is hardened to 45°C to HRC4555, or 40Cr hardened to HRC5055 and then ground to a roughness of Ra0.8μm by a helical grinder. The gearbox wears very slowly during normal operation, and some gearboxs can be used for more than 10 years. If the wear speed is faster, it is necessary to consider whether the selection is correct, whether it is overloaded, and the material, assembly quality or use environment of the helical gear.

It usually occurs on a vertical mounted gearbox, mainly related to the amount of lubricant added and the type of oil. When the vertical installation is installed, it is easy to cause insufficient lubricant. When the gearbox stops running, the transmission gear oil between the motor and the gearbox is lost, and the gears are not protected by the lubrication. When the gearbox is started, the gears are mechanically worn or even damaged due to the lack of effective lubrication.

Broken helical bearing
In the event of a fault, even if the gearbox is well sealed, it is often found that the gear oil in the gearbox is emulsified and the bearing is rusted, corroded and damaged. This is because the condensed water produced by the gear oil temperature rises and cools after mixing for a period of time. Of course, it is also closely related to bearing quality and assembly process.


Troubleshooting editor
Guarantee assembly quality
You can purchase or make some special tools. When disassembling and installing the parts of the gearbox, try to avoid hitting with other tools such as hammers. When replacing gears and helical gears, try to use original parts and replace them in pairs. When assembling the output shaft, pay attention to it. Tolerance fit; use a release agent or red dan oil to protect the hollow shaft to prevent wear and rust or to match the area scale, which is difficult to disassemble during maintenance.


Lubricating oil selection
Helical gear-helical gearbox generally uses 220# gear oil. For heavy-duty, frequent start-up and poor-use gearbox, some lubricating oil additives can be used to keep the gear oil attached to the gear surface when the gearbox stops running. Form a protective film to prevent direct contact between the metal under heavy load, low speed, high torque and start-up. The additive contains a seal regulator and a leak preventer to keep the seal soft and elastic, effectively reducing oil leakage.

Coaxial helical inline gearbox
Installation location selection
When possible, do not use a vertical installation. When installing vertically, the amount of lubricating oil added is much more than that of horizontal installation, which may cause heat generation and oil leakage of the gearbox.


Lubrication maintenance
The gearbox can be maintained according to the “five-set” principle of lubrication work. Every gearbox has a responsible person to check regularly and find that the temperature rise is obvious. If the temperature exceeds 40°C or the oil temperature exceeds 80°C, the quality of the oil will drop or oil. When more copper powder is found and abnormal noise is generated, stop using it immediately, repair it in time, troubleshoot it, and replace the oil. When refueling, pay attention to the amount of oil to ensure that the gear unit is properly lubricated.

Coaxial helical inline gearbox
Maintenance method
For the wear and tear of the gearbox, the traditional solution is repairing after repair welding or brush plating, but both have certain drawbacks: the thermal stress generated by the repair welding high temperature cannot be completely eliminated, which is easy to cause material damage, resulting in bending of the parts. Or rupture; while brush plating is limited by the thickness of the coating, it is easy to peel off, and the above two methods use metal to repair the metal, and can not change the "hard to hard" coordination relationship. Under the combined action of each force, it will still cause again abrasion. In the contemporary Western countries, the repair method of polymer composite materials is often used for the above problems, and it has super-adhesive strength, excellent compressive strength and other comprehensive properties, and can be repaired on site without disassembly and machining. The maintenance of polymer materials has no influence on the thermal stress of repair welding, and the thickness of repair is not limited. At the same time, the metal material of the product does not have the concession, which can absorb the shock and vibration of the equipment, avoid the possibility of re-wearing, and greatly extend the equipment components. The service life saves a lot of downtime for the company and creates huge economic value.
Oil spill problem editing


Cause Analysis
1. The pressure in the fuel tank rises.
In the closed gearbox, each pair of gears meshes with each other to generate heat. According to the Boeing's law, as the running time is lengthened, the temperature inside the gearbox is gradually increased, and the volume inside the chassis is reduced. It does not change, so the pressure inside the box increases, and the lubricating oil in the box is splashed and sprinkled on the inner wall of the reduction chassis. Because the oil has a relatively high permeability, under the pressure inside the box, which one is not tightly sealed, the oil will seep out from there.
2. The structural design of the gearbox is unreasonable and causes oil leakage.
If the designed gearbox does not have a hood, the gearbox cannot achieve equalization, resulting in higher and higher pressure inside the tank and oil leakage.
3, too much fuel
During the operation of the gearbox, the oil pool is stirred a lot, and the lubricating oil splashes everywhere in the machine. If the amount of oil is too much, a large amount of lubricating oil accumulates in the shaft seal, joint surface, etc., resulting in leakage.
4, improper maintenance process
During equipment maintenance, oil leakage may occur due to incomplete removal of dirt on the bonding surface, improper selection of sealant, reverse orientation of the seal, and failure to replace the seal in time. 

Coaxial helical inline gearbox
Treatment plan
The polymer composite material is used to repair and treat the leakage oil of the gearbox. The polymer composite material is made of high molecular polymer, metal or ceramic ultrafine powder, fiber and the like, and is compounded by the curing agent and the curing accelerator. s material. 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. With strong adhesion, mechanical properties, and chemical resistance, it is widely used in metal equipment for mechanical wear, scratches, pits, cracks, leaks, repair of sand holes, etc., as well as various chemical storage tanks. Chemical corrosion protection and repair of reaction tanks and pipelines. For the static sealing point leakage of the gearbox, the surface of the gearbox can be treated with MEGAHUA polymer composite materials and technology without disassembly. The polymer composite material is leaked outside, saving time and effort, and the effect is immediate. The superior adhesion of the product. , oil resistance and 350% stretch, to overcome the impact of the vibration of the gearbox, a good solution for the enterprise can not solve the problem for many years. If the static sealing point leaks during the operation of the gearbox, it can be blocked by the surface engineering technology oil surface emergency repair agent, so as to eliminate the oil leakage.
