The spiral water cooling pipeline 7 can increase the water flow path and improve the water cooling effect.
[0022] Example 3 Figure 3 , 4 As shown, the second circulating water cooling jacket 8 includes a shell whose shape matches the splayed wheel. The shell is a hollow structure (equivalent to a double-layer structure), and the shell is provided with a water inlet connected to the first circulating water cooling jacket 5 and a water outlet 9. The longitudinal section of the shell is a pentagon, including a short vertical side, a bevel side matching the bevels of the large and small bevel gears, a short horizontal side, a long vertical side and a long horizontal side; the opening of the second circulating water cooling jacket 8 is opened on the side where the long horizontal side is located, for the lead screw 4 to extend. The shell is matched with the splayed wheel and is closer to the splayed wheel, which can improve the cooling effect.
[0023] Embodiment 4 The second circulating water-cooling jacket 8 is provided with a plurality of horizontal ribs 10 in the same direction as the pentagon, and a U-shaped waterway is formed between adjacent horizontal ribs 10, and the direction of the horizontal ribs 10 is consistent with the direction of the horizontal axis 1; the water inlet and outlet 9 of the second circulating water-cooling jacket 8 are both located on the side facing the first circulating water-cooling jacket 5, but are located at the front and rear ends of the side.

[0024] The utility model is further described below in conjunction with the accompanying drawings.

In the figure, you can see that the middle part is the casting wheel (composed of large and small bevel gears) and the connected horizontal shaft. For the water cooling of the horizontal shaft, a cylindrical sleeve with a water circulation system is made, such as Figure 5 As shown, the horizontal shaft is sleeved in the middle; then a set of pentahedral sleeves with a water circulation system is made according to the shape characteristics of the eight-shaped wheel, as shown in FIG. Figure 3 , 4 , buckle the splayed wheel inside, the sleeve is made strictly according to the size, and is as close as possible without affecting the normal operation of the horizontal axis and the splayed wheel. Figure 2 It can be seen that the two sleeves are made separately, but the water circulation is connected.

Both circulating water cooling jackets are supported by corresponding brackets and will not interfere with the operation of the device.
