1. Heat and oil leakage of reducer. In order to improve the power of the worm gear wpds80 reducer, nonferrous metals are usually used as the worm gear, and the worm is made of hard steel. Because it is a sliding friction transmission, high heat will occur during the working process, which will make the thermal expansion between the parts and seals of the reducer different, resulting in voids on each cooperation surface, and the oil becomes thinner due to the increase of temperature, Simply form leakage. There are four primary reasons: first, whether the allocation of raw materials is reasonable; second, the surface quality of the meshing and friction surface; third, whether the selection and increase of smooth oil are correct; fourth, the quality of the device and the application environment.
2. Worm gear is worn. The worm gear is usually made of tin bronze. The matched worm data is usually hardened to hrc45-55 with 45 steel, and 40C: Hardened hrc50-55 is also commonly used. It is ground to the roughness Rao by the worm grinder 8 FCM. When the reducer works normally, the worm is like a hardened "file", which keeps filing the worm gear, causing the worm gear to wear. Generally speaking, this kind of wear is very slow. Like some reducers in a factory, they can be used for more than 10 years. If the wear speed is fast, it is necessary to consider whether the selection of reducer is correct, whether there is overload work, raw materials of worm gear, device quality or application environment.
3. The transmission pinion is worn. It usually occurs on the reducer of vertical device, which is mainly related to the increase of smooth oil and the selection of smooth oil. In the vertical device, it is very simple to form a lack of smooth oil. When the reducer stops working, the transmission gear oil between the motor and the reducer is lost, the gear can not be smoothly maintained, and the useful smoothness can not be obtained during starting or working, resulting in mechanical wear and even damage. The solution is to clean the inside of the reducer with the gearbox cleaning and maintenance machine in time.
4. The worm bearing is damaged. When the wpds80 reducer with hard tooth surface breaks down, even if the gearbox is well sealed, the factory often finds that the gear oil in the reducer has been emulsified and the bearing has been rusted, corroded and damaged. This is because the gear oil is formed by the condensation of water after heating and cooling during the operation and shutdown of the reducer; Of course, it is also closely related to bearing quality and device technology
