The connection with the first reinforcing rib 11 can, on the one hand, ensure that the oil drain port 20 can completely discharge the lubricating oil, and on the other hand, the bottom of the shell body 1 can be protected by the first reinforcing rib 11 to avoid damage to the reducer shell caused by the impact of some sand and gravel during driving. The reinforcing effect of the first reinforcing rib 11 is utilized to a certain extent, so that the structural strength of the oil drain port 20 located at the bottom of the shell body 1 is improved, and then the first end and the second end of the second reinforcing rib 12 are respectively connected to the refueling port 10 and the oil drain port 20, so as to further strengthen the structural strength of the refueling port 10 and the oil drain port 20, and avoid the problem of stress concentration in the structure near the refueling port 10 and the oil drain port 20.

[0028] It is understandable that the first reinforcing rib 11 and the second reinforcing rib 12 can be provided in plurality, so as to further improve the structural strength of the reducer housing, which is not specifically limited here.

[0031] Combination Figures 1 to 4 As shown, a total of three third reinforcing ribs 211 are provided on the top of the outer wall of the first cylindrical portion 21 (i.e., the portion on the positive side of the Z axis in the figure), and a first preset angle is formed between two adjacent third reinforcing ribs 211, for example Figure 1 As can be seen from the figure, one third reinforcing rib 211 is completely parallel to the X-axis in the figure, while the other two third reinforcing ribs 211 are located on both sides and form a first preset angle ( Figure 1 At the same time, one of the two third reinforcing ribs 211 on both sides is inclined in the positive direction of the Y axis, and the other is inclined in the negative direction of the Y axis, so that Figure 1 A basically symmetrical arrangement structure is formed. In practical applications, the inclination direction of the third reinforcing rib 211 caused by the first preset angle can be designed as needed. The inclination direction arrangement scheme here is only an example and is not specifically limited.

[0032] In this way, by providing the third reinforcing rib 211 , the top of the first cylindrical portion 21 is structurally reinforced, thereby ensuring that the strength of the reducer housing meets the requirements.

[0033] It should be noted that the number of the third reinforcing ribs 211 is not specifically limited here, and can be any number of two or more, as long as sufficient structural reinforcement effect can be achieved.

[0036] In this way, the fourth reinforcing ribs 212 are parallel to each other, and their first ends are arranged on the shell body 1, and their second ends are arranged on the first cylindrical portion 21, thereby improving the structural strength of the first cylindrical portion 21, especially the strength along the axial direction of the first cylindrical portion 21.

The second end of the second cylindrical portion 22 (with Figure 2 Take the second cylindrical portion 22 in the figure as an example, that is, along the positive end of the Y axis in the figure; Figure 3 For example, the second cylindrical portion 22 in the figure (i.e., the end opposite to the Y axis in the figure) is provided with a drive shaft hole 220 to communicate with the inner cavity of the shell body 1, thereby allowing the drive shaft and other parts to pass through. The two fourth reinforcing ribs 212 are connected to the outer wall of the second cylindrical portion 22 through the first end (the fourth reinforcing rib 212 passes through the sixth reinforcing rib 214 in the figure, and the sixth reinforcing rib 214 will be described in detail later), and are connected to the outer edge of the second end of the first cylindrical portion 21 through the second end, combined with Figure 3 As shown, two of the four fourth reinforcing ribs 212 are connected to the outer wall of the second cylindrical portion 22 through the first end, and are connected to the outer edge of the second end of the first cylindrical portion 21 through the second end.

[0039] In this way, the second cylindrical portion 22 and the first cylindrical portion 21 are connected together by at least one fourth reinforcing rib 212, thereby playing a further structural reinforcement role and meeting the strength requirement of the reducer housing.

[0040] Furthermore, a plurality of fifth reinforcing ribs 213 are disposed on the outer wall of the first cylindrical portion 21 . The fifth reinforcing ribs 213 surround the first cylindrical portion 21 and are arranged to cross the fourth reinforcing ribs 212 and the third reinforcing ribs 211 .
