[0029] Specifically, in this embodiment, the outer shell includes a box cover 7, a box body 8 and a base 9. The box body 8 is detachably connected to the box cover 7 and the base 9 respectively. A foot 20 is provided at the bottom of the box body 8. The power output shaft 2 is rotatably connected to the box cover 7 through an output end bearing 11. The power input shaft 1 is rotatably connected to the base 9 through an input end bearing 10. The power input shaft 1 and the power output shaft 2 are vertically arranged.

[0030] In this embodiment, the transmission structure includes a first gear 3, a second gear 4, a third gear 5 and a fourth gear 6. The first gear 3 is arranged on the power input shaft 1, and the first gear 3 is meshed with the second gear 4. The first gear 3 and the second gear 4 are both bevel gears. The second gear 4 and the third gear 5 are both arranged on the support shaft 12 and are coaxially arranged. The support shaft 12 is rotatably connected to the box cover 7 through a transmission bearing 13. The fourth gear 6 is arranged on the power output shaft 2, and the third gear 5 is meshed with the fourth gear 6.

[0031] In this embodiment, an oil-slinging plate 14 is also provided on the power input shaft 1. The oil-slinging plate 14 and the first gear 3 are coaxially arranged. The oil-slinging plate 14 is located in the housing 8. The outer edge of the oil-slinging plate 14 is provided with a notch along the circumference of the oil-slinging plate 14. The edge of the oil-slinging plate 14 can enter below the liquid level of the lubricating oil in the housing 8. The oil-slinging plate 14 is used to throw the lubricating oil in the housing 8 into the lubrication channel structure.
