It should be noted that, since the mounting position 100 is generally circular, taking the mounting position 100 between the right module 13 and the right cover 23 as an example, as shown in fig. 2, a semicircular groove at the upper end of the right module 13 and a semicircular groove at the lower end of the right cover 23 may enclose the mounting position 100, and therefore, when the gasket 4 passes through the semicircular groove, the gasket may be embedded along the annular inner wall of the semicircular groove.

Referring to fig. 6, in some embodiments of the present disclosure, the gasket 4 between the left module 11 and the left cover 21, the gasket 4 between the right module 13 and the right cover 23, and the gasket 4 between the middle module 12 and the corresponding middle cover 22 are integrated, so as to further improve the sealing performance between the box cover 2 and the box body 1. When the gasket 4 is of an integral structure, the gasket 4 needs to be replaced at the same time when the number of the intermediate modules 12 and the intermediate cover 22 needs to be increased or decreased.

Referring to fig. 3, in some embodiments of the present disclosure, the right end inner side of the left module 11, the right end inner side of the left cover 21, the left end inner side of the right module 13, the left end inner side of the right cover 23, the inner sides of the left and right ends of the middle module 12, and the inner sides of the left and right ends of the middle cover 22 are each provided with a rib 400 protruding inward, and adjacent ribs 400 contact with each other to form a seal. Under the action of the reinforcing ribs 400, the overall strength of the gear box body can be increased, and the overall sealing performance of the gear box body can be improved. In addition, the reinforcing ribs 400 can occupy the space inside the tank body 1 on one hand, which is beneficial to reducing the use amount of oil; on the other hand, it is beneficial to increase the widths of the insertion part 200 and the positioning groove 300, so as to reduce the processing difficulty of the insertion part 200 and the positioning groove 300.

Referring to fig. 1, in some embodiments of the present application, the lower ends of the left module 11, the middle module 12, and the right module 13 are each provided with a mounting hole 500, and the outer side surfaces of the left module 11, the middle module 12, and the right module 13 are each recessed inward with a relief groove 600 for avoiding the mounting hole 500. Under the action of the abdicating groove 600, the gear box body can be conveniently installed and fixed through the installation hole 500; simultaneously, because the groove 600 of stepping down is inside sunken formation, consequently, the sunken part that forms the groove 600 of stepping down can occupy the space of case body 1 inside, is favorable to reducing the quantity of fluid.
