How To Improve The Efficiency Of The Worm Gear Reducer? Nov 12, 2019
In order to improve the efficiency, the worm gear reducer generally uses non-ferrous metal as the worm wheel, and the worm uses the hard steel. Because it is a sliding friction drive, it will generate higher heat during the operation, making the worm gear reducer parts. The difference in thermal expansion between the seal and the seal creates a gap in each mating surface, and the oil becomes thinner due to an increase in temperature, which is liable to cause leakage. There are four main reasons. First, whether the material is reasonable. Second, the surface quality of the friction surface. Third, the choice of lubricating oil, whether the amount of addition is correct, and the fourth is the assembly quality and the use environment.

The worm gear reducer is generally made of tin bronze. The paired worm material is generally hardened to 45°C to HRC45-55. It is also commonly used 40C: hardened HRC50-55. Grinding to roughness RaO.8fcm by worm grinder, the worm gear reducer is normal. In operation, the worm acts like a hardened boring tool, constantly boring the worm gear, causing the worm gear to wear. In general, this wear is very slow, like some worm gear reducers in a factory can be used for more than 10 years. If the wear speed is fast, it is necessary to consider whether the selection of the worm gear reducer is correct, whether there is overload operation, the material of the worm gear, the assembly quality or the use environment. Transmission small helical gear grinding, generally occurs in the vertical installation of the worm gear reducer, mainly related to the amount of lubricant added and the choice of lubricant. When the vertical installation is installed, it is easy to cause insufficient oil quantity. When the worm gear reducer stops running,

The transmission gear oil between the motor and the worm gear reducer is lost, the gear can not get the proper lubrication protection, and the effective lubrication during the starting or running process leads to mechanical wear and even damage.
