WPWDS Series Universal Speed Worm Gearboxe
Worm gear reducer design To improve its application power, the worm gear adopts non-ferrous metals as the primary data. The worm is generally made of hard steel, so it is easy to generate a large amount of heat during use, plus the influence of the ambient temperature. The temperature of the reducer is challenging to control—the range of working temperature. The working temperature of the worm gear reducer should be maintained at -40℃~40℃. When the ambient temperature is lower than 0 ℃, it should be heated before entirely dissolving the lubricating oil or using low freezing point lubricating oil.

Common Faults and Causes of Worm Gearboxes:
1. The reducer heats up and leaks oil. To improve efficiency, worm gear reducers generally use non-ferrous metals as worm gears, and worms use more rigid steel. Due to the sliding friction transmission, more heat will be generated during operation, which will cause differences in thermal expansion between the parts of the reducer and the seal, thus forming gaps in each mating surface. The lubricating oil will become thinner due to the increase in temperature, which is easy to cause leakage. . There are four main reasons for this situation. First, the matching of materials is unreasonable; second, the quality of the meshing friction surface is poor; third, the selection of the amount of lubricating oil added is incorrect; fourth, the assembly quality and use environment are poor.
2. The worm gear is worn. The worm gear is generally made of tin bronze, and the paired worm material is hardened to HRC4555 with 45 steel or 40Cr hardened to HRC5055 and then ground to a roughness of Ra0.8μm by a worm grinder. The reducer wears very slowly during regular operation; some reducers can be used for more than ten years. If the wear rate is fast, it is necessary to consider whether the selection is correct, whether it is overloaded, and the material of the worm gear, the quality of assembly, or the use environment.
3. The transmission of small helical gear is worn. It generally occurs on vertically installed reducers, mainly related to the amount of lubricating oil added and the type of oil.
a.When installed vertically, it is easy to cause insufficient lubricating oil.
c.When the reducer stops running, the transmission gear oil between the motor and the reducer is lost. and the gears cannot be properly lubricated and protected.
4. Of course, it is also closely related to the bearing quality and assembly process.
