Common problems and reasons of reducer
2023/04/11
Reducer is a kind of transmission machinery with compact structure, large transmission ratio, and self-locking function under certain conditions, and it is easy to install, reasonable structure, and is more and more widely used. Common problems and their causes. 1) The reducer is heated and leaks, (2) the worm gear is worn, (3) the transmission small helical gear is worn, and (4) the bearing (at the worm) is damaged. 1. The reducer is hot and leaks. Reducer in order to improve efficiency, generally use non-ferrous metal as worm gear, worm is made of harder steel, because it is sliding friction transmission, in the process of operation, will produce higher heat, so that the reducer parts and seal thermal expansion difference, thereby producing gaps in each mating surface, and oil due to the increase of temperature thinner, easy to cause leakage. There are four main reasons, one is whether the material matching is reasonable, the second is the surface quality of the meshing friction surface, the third is the choice of lubricating oil, whether the amount of addition is correct, and the fourth is the assembly quality and use environment. 2. Worm gear wear. The worm gear is generally made of tin bronze, and the paired worm material is generally hardened to HRC45-55 with 45 steel, and 40C: hardened HRC50-55, ground to roughness RaO by worm grinder. 8 fcm, when the reducer is operating normally, the worm is like a hardened "file", constantly filing the worm gear, so that the worm gear wears. Generally speaking, this wear is very slow, like some reducers in a certain 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 reducer is correct, whether there is overload operation, the material of the worm gear, the assembly quality or the use environment.
