Since the defoaming portion 80 has a plurality of defoaming ribs (not shown), the foam generated by the flow of the lubricating oil can be rapidly eliminated. The lubricant can then be pumped into the body channel 30 again by means of a suitable oil pump.
Referring to fig. 7, 8, 10 and 11, during the process of the lubricant passing through the bearing seat flow passage 60, the lubricant will impact the step flange 66, so that part of the lubricant can be sprayed out from the oil outlet hole 68, and the lubricant acts on the meshing position of the transmission gear 22 and the driven gear 16.

The third guide flow passage 104 corresponds to the first oil hole 44 of the driven gear shaft 24. So that the lubricant can enter the upper lid channel 106 from the body channel 30. The lubricating oil is delivered from the upper cover flow passage 106 and then enters the axial portion 42 through the first oil hole 44.
Referring to fig. 14, the lubricant oil flows into the upper cover flow passage 106 through the body flow passage 30 and flows to the driven gear shaft flow passage 40 after being output; the lubricating oil flows out of the driven gear shaft flow passage 40, is injected into the driven gear bearing housing 50, and flows into the housing flow passage 60. The lubricant is injected into the transmission gear bearing housing 52 through the bearing housing flow passage 60 and enters the defoaming portion 80 through the second guide flow passage 74. Since the defoaming portion 80 has a plurality of defoaming ribs (not shown), the foam generated by the flow of the lubricating oil can be rapidly eliminated. The lubricant can then be pumped into the body flow passage 30 again.
As described above, since the electric motor 18 and the driven gear 16 are integrated in the same body 10 and adjacent to each other, the stroke of the oil circuit system can be shortened to improve the lubrication and cooling effects. In addition, the present embodiment further guides and sprays the lubricating oil to the meshing position of the transmission gear 22 and the driven gear 16, so that the friction between the two gears can be reduced, and the temperature generated by the relative motion of the two gears can be reduced.
