What is the oil leakage of the reducer when it heats up

        The plane double-envelope reducer is a problem that many manufacturers often encounter in production, but sometimes due to the low experience of the workers, sometimes it is difficult to correctly discharge the plane double-envelope reducer, which will cause some impact on the production. , Let’s ask the experienced old technicians of Yongtengxiang plane double envelope reducer manufacturer to tell us about several problems that often occur in plane double envelope reducers: the common problem is the plane double envelope reducer. Heat generation, oil leakage, worm gear wear, etc., some workers are at a loss when they encounter the problems just mentioned, so today we will focus on this problem: In order to improve efficiency, flat double-envelope reducers generally The worm wheel is made of non-ferrous metal, and the worm is made of harder steel. Because it is a sliding friction drive, it will generate higher heat during operation, which will cause differences in thermal expansion between the parts and seals of the reducer, and thus There is a gap in the mating surface, and the oil becomes thinner due to the increase in temperature, which is easy to cause leakage.There are four main reasons,One is whether the collocation of materials 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.The worm wheel of the plane double envelope reducer is generally made of tin bronze, and the matched worm material is generally hardened with 45 steel to HRC45-55, and 40C: hardened HRC50-55 is commonly used, and it is ground by a worm grinder to a roughness of RaO.8fcm , When the reducer is running normally, the worm is like a hardened file, which keeps filing the worm wheel, causing the worm wheel to wear.Generally speaking, this kind of wear is slow.
