The Main Cause Of Oil Leakage Of Worm Gear Reducer
Release Date:16/11/2019
According to the user's reflection, when using the worm gear reducer, oil leakage occurs. So, do you know what caused it? Today, the machine reducer will analyze the temperature of the worm gear reducer according to the situation reflected by the user. High and thin, easy to cause leakage, the main reasons are as follows:
1. The assembly quality is not up to the requirement. When the cover of the reducer is repaired and installed, the joint sealing is not good, and oil leakage may occur.
2. The structure of the reducer is unreasonable and causes oil leakage. If the designed reducer does not have a hood or the hood is too small, the reducer cannot achieve equalization, and the pressure inside the box will rise and oil leakage will occur.
3. The working environment of the reducer causes oil leakage. If the environment is dusty, the ventilation cover is poorly ventilated, and the pressure equalization, high temperature and harmful medium cannot be achieved, so that the seal is aged and oil leakage may occur.
4. In a closed reduction cabinet, each pair of gears meshes and the gear is immersed in oil to generate heat. With the long running time, the temperature inside the gearbox is gradually increased, the pressure inside the box is increased, and the lubricating oil in the box is splashed and sprinkled on the inner wall of the reduction casing, because the viscosity of the lubricating oil decreases with the increase of temperature, the oil The permeability is stronger, and under the action of the pressure inside the box, the lubricating oil leaks along the partition surface or the shaft is tightly sealed.
In order to improve efficiency, worm gear reducers generally use non-ferrous metals for worm gears, while worms use harder steel. Because it is a sliding friction transmission, more heat is generated during operation, which causes a difference in thermal expansion between the parts of the worm reducer and the seal, thereby forming a gap in each mating surface, so that the worm gear reducer leaks oil.
Therefore, the Taiwan machine reducer company here to remind the majority of users in order not to affect the production of the worm gear reducer, please note that the above mentioned points cause the worm gear reducer oil leakage.
