A collecting tank 7 is provided inside the reduction gear box 1 below the movable chamber, and a strip groove 6 communicating with the movable chamber is opened on the top inner wall of the collecting tank 7. An oil injection pipe 13 with a nozzle at the bottom is installed in the movable chamber above the worm 4. An oil storage tank 9 is installed on the rear side of the reduction gear box 1, and an oil extraction pipe 11 is provided at the bottom of the oil storage tank 9, which passes through the reduction gear box 1 and extends into the collecting tank 7. A circulating pump 10 for extracting lubricating oil in the oil storage tank 9 is installed on the top of the oil storage tank 9, and the outlet of the circulating pump 10 is connected to the oil injection pipe 13 through an oil delivery pipe 12.

[0019] Specifically, a filter screen 8 is installed in the inner cavity of the collecting tank 7 .

[0020] In this embodiment, the filter 8 is a filter screen or filter membrane with a filtration accuracy generally between 5 microns and 25 microns, or a microporous filter membrane, which is used to filter the lubricating oil that lubricates the worm wheel 5 and the worm 4.

[0021] Specifically, an oil filling port 15 is provided on the top of the oil storage tank 9 .

[0023] Specifically, two groups of cooling fins 16 are provided on a side of the oil storage tank 9 away from the reduction gearbox 1 .

[0024] In this embodiment, the oil storage tank 9 is made of aluminum, and the provision of the heat sink 16 is beneficial to the heat dissipation of the lubricating oil in the oil storage tank 9 .

[0025] Specifically, there is a gap between the two groups of heat sinks 16, and the inner cavity of the oil storage tank 9 is equipped with a rotating shaft 14 with both ends passing through the oil storage tank 9.
