Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0036] Refer to Figure 1 With Figure 2 , Figure 3 , Figure 5 , Figure 6 , the utility model provides a technical scheme: a novel bevel gear differential shell assembly, including upper shell 1, upper shell 1 lower end is installed with lower shell 2, and the upper surface of lower shell 2 is provided with connecting groove 7, and the lower surface of upper shell 1 is fixedly connected with connecting frame 3, and connecting groove 7 and connecting frame 3 are shape compatible, and connecting groove 7 is fixedly connected with threaded sleeve 14 inside, and threaded sleeve 14 and lower shell 2 are all provided with threaded groove inside, and the threaded groove is screw connected with bolt 4 inside, and upper shell 1 and lower shell 2 are provided with mounting structure.

[0037] When the upper shell 1 and the lower shell 2 of the bevel gear differential are installed, first, the upper shell 1 is horizontally aligned with the lower shell 2, then the upper shell 1 is installed so that the connecting frame 3 is inserted into the connecting groove 7, and the shape of the connecting groove 7 and the connecting frame 3 is matched, so that the upper shell 1 and the lower shell 2 can be preliminarily positioned, and as the connecting frame 3 is completely inserted into the connecting groove 7, the threaded groove provided in the sleeve and the lower shell 2 is horizontally aligned and interconnected at this time, at this time, the bolt 4 is inserted and rotated, so that the bolt 4 is screw connected along the threaded sleeve 14 and the threaded groove, until the bolt 4 tightly fixes the upper shell 1 and the lower shell 2 together, and the upper shell 1 and the lower shell 2 are pre-fixed between the connecting groove 7 and the connecting frame 3, which ensures the connection stability and firmness between the upper shell 1 and the lower shell 2, thereby improving the overall performance and service life of the bevel gear differential.

[0038] Refer to Figure 2 With Figure 3 , Figure 4 , Figure 5 , Figure 6、 Figure 7 The mounting structure comprises a limiting hole 13 formed in the connecting frame 3, a sliding column 18 slidably connected in the connecting groove 7, a semicircular limiting block 20 fixedly connected at the end of the sliding column 18, and the size of the semicircular limiting block 20 is adapted to the shape of the limiting hole 13.

A limiting strip 16 is fixedly connected in the connecting groove 7, a limiting groove 15 is formed in the connecting frame 3, the shape of the limiting groove 15 is adapted to the limiting strip 16, and one side of the limiting groove 15 is fixedly connected with the threaded sleeve 14. An inclined plate 17 is fixedly connected on both sides of the connecting frame 3, and an inclined groove 12 is formed in the connecting groove 7, and the shape of the inclined groove 12 is adapted to the inclined plate 17.

[0039] When the upper shell 1 and the lower shell 2 of the bevel gear differential are installed, the upper shell 1 is first aligned horizontally with the lower shell 2, and then the upper shell 1 is installed so that the connecting frame 3 is inserted into the connecting groove 7. At this time, the connecting frame 3 will drive the inclined plate 17 to slide along the inclined groove 12 during the process of being inserted into the connecting groove 7. Since the shape of the inclined groove 12 is adapted to the inclined plate 17, the inclined plate 17 will gradually approach during the sliding process, thereby driving the connecting frame 3 to move closer to the middle to correct the movement of the connecting frame 3. At the same time, the connecting frame 3 will extrude the semicircular limiting block 20 during the movement, causing the semicircular limiting block 20 to drive the sliding column 18 to slide into the connecting groove 7. At this time, the spring 19 is extruded to deform. When the connecting frame 3 is completely inserted into the connecting groove 7, the limiting hole 13 formed in the connecting frame 3 is horizontally aligned with the semicircular limiting block 20.

Since the screw 5 and the mounting plate 6 are threadedly connected, the mounting plate 6 is moved during the rotation of the screw 5. The mounting plate 6 slides along the telescopic column 11 during the movement. At this time, the mounting pad 9 contacts the mounting plate 6. Since the mounting pad 9 is an antiskid rubber pad, the friction between the mounting plate 6 and the mounting pad 9 can be increased, the connection firmness between the mounting plate 6 and the mounting groove 8 is further improved, and the mounting plate 6 in the mounting groove 8 is prevented from shaking. Meanwhile, the telescopic column 11 can guide and limit the mounting plate 6, so that the mounting plate 6 is more stable during the movement and does not deviate, and the installation precision is further improved.

At this time, when the rotating plate 21 is rotated, the rotating plate 21 drives the screw 5 to rotate. Since the screw 5 and the mounting plate 6 are threadedly connected, the mounting plate 6 is moved during the rotation of the screw 5. The mounting plate 6 slides along the telescopic column 11 during the movement. At this time, the mounting pad 9 contacts the mounting plate 6. Since the mounting pad 9 is an antiskid rubber pad, the friction between the mounting plate 6 and the mounting pad 9 can be increased, the connection firmness between the mounting plate 6 and the mounting groove 8 is further improved, and the mounting plate 6 in the mounting groove 8 is prevented from shaking.
