Detailed Description
When gas with certain pressure is formed in the shell of the speed reducer and needs to be discharged, the oil-containing mixed gas is incompletely separated from the gas under the prior art, so that lubricating oil is sprayed out along with the gas, and the lubricating oil in the shell is lost.

However, since the gas introduced into the oil cannot enter from the bottom of the oil deposit, the oil can be introduced only from one side of the oil liquid level, and the gas mixture emerges from the other side of the oil deposit in the form of bubbles. If too deep oil is introduced, it is necessary to build up sufficient pressure in the gear housing, which is obviously not permissible. Therefore, when an effective filtering measure of contacting and dissolving the oil in the mixed gas by the oil is adopted, only the contact absorption of the surface layer of the oil liquid can be adopted.
