Reasons for common problems of reducer

1. Reducer heat and oil leakage worm gear reducer In order to improve efficiency, non-ferrous metals are generally used as worm gears, and worms are made of harder steel. Because it is a sliding friction transmission, higher heat will be generated during operation , Make the difference in thermal expansion between the parts and the seal of the reducer, thereby creating gaps in the mating surfaces, and the oil becomes thinner due to the increase in temperature, which is easy to cause leakage. There are four main reasons for this situation: one is the unreasonable collocation of materials, the second is the poor surface quality of the meshing friction surface, the third is the incorrect choice of lubricant addition, and the fourth is the poor assembly quality and use environment.

2. Worm gear wear Worm gear is generally made of tin bronze, and the matched worm material is generally hardened to HRC45-55 with 45 steel, and 40C hardened HRC50-55 is commonly used, and it is ground to a roughness of RaO.8fcm by a worm grinder, and the reducer runs normally. At this time, the worm is like a hardened "file", constantly filing the worm gear, causing the worm gear to wear. Generally speaking, this kind of wear is very slow, and some reducers in a certain factory can be used for more than 10 years. If the wear rate is fast, it is necessary to consider whether the selection of the reducer is correct, whether there is an overload operation, the material of the worm gear, the assembly quality or the use environment and other reasons. -- Brush DC Gear Motors Suppliers

3. The wear of the transmission pinion helical gear generally occurs on the reducer installed vertically, which is mainly related to the amount of lubricant added and the type of oil. When installed vertically, it is easy to cause insufficient lubricating oil. When the reducer stops running, the transmission gear oil between the motor and the reducer is lost, and the gears cannot get the proper lubrication protection. When the reducer is started, the gears are not effectively lubricated, causing mechanical wear and even damage.

4. When the worm bearing is damaged, even if the gearbox 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 the condensate produced by the gear oil temperature rises and cools down after the reducer has been running for a period of time is mixed with water. Of course, it is also closely related to bearing quality and assembly process.
