1. Gearbox heating and oil leakage
In order to improve efficiency, WPWKV40, WPWKV50, WPWKV60, WPWKV70, WPWKV80
Worm gear reducer manufacturers typically use non-ferrous metals as worm gears, while worm gears use hard steel. Due to the Sliding friction drive, more heat will be generated during operation, which will lead to the difference in thermal expansion between the reducer components and seals, thus forming a gap on each mating surface. Due to the increase in temperature, the lubricating oil will become thinner, which can easily cause leakage. There are four main reasons for this situation. Firstly, the material combination is unreasonable; Secondly, the surface quality of the meshing friction surface is poor; Thirdly, the selection of lubricating oil addition is incorrect; Fourthly, the assembly quality and usage environment are poor.
2. Worn worm gear
Worm gears are usually made of tin bronze, and the matched worm material is hardened to HRC4555 using 45 steel, or to HRC5055 using 40Cr, and then ground to a roughness of Ra0.8m using a worm grinder. Reducers wear slowly during normal operation, and some reducers can be used for more than 10 years. If the wear rate
To achieve fast speed, it is necessary to consider whether the selection is correct, whether it is overloaded, the material, assembly quality, or usage environment of the worm gear.
3. Worn transmission bevel gear
Usually occurs on vertically installed gearboxes, which is mainly related to the amount and type of lubricating oil. When installed vertically, it is easy to cause insufficient lubricating oil. When the reducer stops running, the oil in the transmission gear between the motor and the reducer will be lost, and the gear cannot receive appropriate lubrication protection. When the reducer
When starting, due to lack of effective lubrication, the gears may be mechanically worn or even damaged.
4. Worm bearing damaged
In case of failure, even if the reducer is well sealed, it is often found that the Gear oil in the reducer is emulsified, and the bearing is rusted, corroded and damaged. This is because after the reducer has operated for a period of time, the condensed water generated after the temperature of Gear oil rises and cools is mixed with water. Of course, it is also closely related to bearing quality and assembly process.
