What are the hard tooth surface reducer failures and troubleshooting methods? 1. The reducer heats up and leaks oil. In order to improve the power of worm gear reducers, non-ferrous metals are usually used as worm gears, and the worm gear is made of harder steel. Because it is a sliding friction transmission, high heat will occur during the work, making the parts of the reducer and hard What are the troubleshooting methods of the gear reducer?
1. The reducer heats up and leaks oil. In order to improve the power of worm gear reducers, non-ferrous metals are usually used as worm gears, and the worm gear is made of harder steel. Because it is a sliding friction drive, high heat will occur during the work, so that the parts and seals of the reducer The difference in thermal expansion occurs between the co-operative surfaces, and the oil becomes thinner due to the increase in temperature, which simply forms a leak. There are four main reasons. One is whether the allocation of raw materials is reasonable, the other is the surface quality of the meshing friction surface, the third is the selection of smooth oil, and whether the increase is correct. The fourth is the quality of the device and the operating environment.
2. Worm gear wear. The worm gear is usually made of tin bronze. The paired worm data is usually hardened with 45 steel to HRC45-55, and 40C: hardened HRC50-55 is used, and the roughness is RaO. 8 fcm, when the reducer works normally, The worm is like a hardened "file", constantly rasping the worm gear, causing the worm gear to wear out. Generally speaking, this kind of wear is very slow. Some reducers in a certain factory can be used for more than 10 years. If the wear speed is high, we must consider whether the selection of the reducer is correct, whether there is an overload, the raw material of the worm gear, the quality of the device, or the operating environment.
3. The transmission small helical gear is worn. It usually occurs on the reducer of the vertical device, which is mainly related to the increase of the smooth oil and the selection of the smooth oil. In the vertical device, it is very simple to form a lack of smooth oil and oil. When the reducer stops working, the transmission gear oil between the motor and the reducer is lost, and the gears cannot get the smooth maintenance they should have. The smoothness caused mechanical wear and even damage. Solution Clean the inside of the reducer with the gear box cleaning and maintenance machine in time.
4. Worm bearing is damaged. When a hard-toothed surface gearbox has a problem, even if the gearbox is well sealed, the factory still often finds that the gear oil in the gearbox has now been emulsified, and the bearings have rusted, corroded and damaged. In gear oil, it is formed by the condensation of water that occurs after the heat becomes cold; of course, it is also closely related to the quality of the bearing and the technical means of the device.
