The baffle isolates the cavity from the outside air. When the lubricating oil is added, the cavity is not connected to the outside, and the lubricating oil is stored in the liquid storage cavity, thereby preventing dust and water vapor in the air from entering the cavity, thereby ensuring the working effect of the device".
