Starred-River worm gear reducer is a kind of transmission machine with compact structure, large transmission ratio, and self-locking function under certain conditions. It is one of the commonly used reducers. Among them, Starred-River hollow shaft worm Street reducer not only has the above characteristics, but also has convenient installation and reasonable structure, which is more and more widely used.
A helical gear reducer is installed at the input end of the worm gear and worm reducer in Starred-River hollow shaft worm gear reducer. The multi-stage reducer can achieve very low output speed. It is a combination of helical gear and worm gear stages, and has higher efficiency than pure single-stage worm gear reducer. Besides, it has low vibration, low noise and low energy consumption.
The performance and quality of Starred-River reducer are excellent, but in some cases there will be heating and oil leakage failure. The specific reasons are as follows:
In order to improve the efficiency of Starred-River turbine reducer, non-ferrous metal is generally used as worm wheel and worm is made of harder steel. Because it is sliding friction transmission, higher heat will be generated during operation, which makes the thermal expansion difference between parts and seals of the reducer, thus creating clearance at all mating surfaces. Oil is easy to leak due to the increase of temperature and dilution. Leakage.
There are four main reasons for heat and oil leakage in Starred-River reducer.
1. Material collocation is reasonable.
2. Surface quality of meshing friction surface.
3. The choice of lubricating oil and the correct amount of lubricating oil added.
4. Assembly quality and service environment.
Of course, this situation is still very rare. Star River reducer manufacturers are trying to do better, so that all products are free of any problems. If you encounter problems, we will actively solve them for you after sales.
