The upper cover 12 is fixed to the upper end of the base 11 and closes the lower gear compartment 111. The top cover 13 is fixed to the top of the upper gear compartment 121.

A first fixed shaft 16 and a second fixed shaft 17 are fixedly mounted in the lower gear compartment 111. A lower gear system is installed between the main shaft 14, the first fixed shaft 16, the second fixed shaft 17, and the output shafts 15.
[0036] The oiling structure 2 is fixedly installed through the mounting hole 122. An upper gear system is installed between the oiling structure 2 and the main shaft 14. Driven by the main shaft 14, the oiling structure 2 lifts the lubricating oil in the lower gear chamber 111 to the upper gear chamber 121. The lubricating oil lifted to the upper gear chamber 121 flows back to the lower gear chamber 111 through the oil hole 123.
[0037] In the above technical solution, a combination of base 11 and upper cover 12 is adopted to form lower gear chamber 111 and upper gear chamber 121. The rotation of main shaft 14 drives the oil supply structure 2 to operate, so that the lubricating oil in lower gear chamber 111 is lifted into upper gear chamber 121, and then flows back into lower gear chamber 111 from oil hole 123.
[0038] During the return flow, the lubricating oil lubricates the mating area between the main shaft 14 and the upper gear housing 121, as well as the positions of the first fixed shaft 16 and the second fixed shaft 17.

The driving gear 31 meshes with the first driven gear 33, and the end gear 32 is driven by meshing with either the first driven gear 33 or the second driven gear 34. The first fixed shaft 16 and the first driven gear... A first bearing 331 is fitted between the second fixed shaft 17 and the second driven gear 34; a second bearing 341 is fitted between the second fixed shaft 17 and the second driven gear 34; a third bearing 1211 is fitted between the main shaft 14 and the upper gear compartment 121; a fourth bearing (not shown) and a shaft seal (not shown) are fitted between the output shaft 15 and the lower gear compartment 111, with the shaft seal sealing the lower part of the fourth bearing; the upper end of the main shaft 14 passes through the top cover 13, and a first shaft seal 133 is fitted between the main shaft 14 and the top cover 13.

[0041] In the above technical solution, the transmission ratio between the first driven gear 33 and the end gear 32 is 1:4, that is, the first driven gear 33 rotates 1 revolution and the end gear 32 rotates 4 revolutions.
[0042] See Figure 3As shown, multiple oil holes 123 are provided, corresponding to the first fixed shaft 16 and the second fixed shaft 17 respectively.
[0043] With the oil hole 123 corresponding to the first fixed shaft 16 and the second fixed shaft 17, the lubricating oil will directly act on the first fixed shaft 16 and the second fixed shaft 17 during the oil return process, and perform targeted lubrication.
[0044] See Figure 3 As shown, a lower oil port 124 is distributed in a ring at the bottom edge of the upper gear compartment 121, and the lower oil port 124 corresponds to the output shaft 15.

[0046] See Figure 3 As shown, the end of the lower oil port 124 that is away from the main shaft 14 is inclined downward.
[0047] See Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the oiling structure 2 includes a cylinder 21 and a rotating body 22. A flange 23 is machined on the top of the cylinder 21. The cylinder 21 passes through the mounting hole 122. The flange 23 is located inside the upper gear compartment 121 and is fixed to the upper cover 12. The outer wall of the rotating body 22 fits the inner wall of the cylinder 21. Multiple spiral grooves 24 are distributed on the outer wall of the rotating body 22. The upper and lower ends of the spiral grooves 24 are through. A rotating shaft 25 is integrally machined at the top axis of the rotating body 22. A fifth bearing is fitted between the rotating shaft 25 and the cylinder 21. The lower end of the cylinder 21 is clearance-fitted with the inner bottom surface of the lower gear compartment 111. When the rotating body 22 rotates at high speed, the lubricating oil in the lower gear compartment 111 is lifted upward through the spiral grooves 24 to the upper gear compartment 121. The upper gear system is installed between the main shaft and the rotating shaft 25.
[0048] In the above technical solution, the rotating body 22 rotates at high speed under the action of the upper gear system, and drives the lubricating oil from the lower gear compartment 111 to the upper gear compartment 121 through the spiral groove 24. During the lifting process, the lubricating oil passes through the fifth bearing and lubricates the fifth bearing.

[0051] See Figure 3 As shown, an oil injection hole is drilled in the upper cover 12, and a plug 1222 is sealed at the oil injection hole.
[0052] The design of the plug 1222 facilitates oiling during equipment maintenance and allows for inspection after oil is collected using devices such as droppers, enabling timely replacement of the lubricating oil.
