A screw hole 44 matching the first positioning bolt 43 is formed at one end of the rotor 3. The first positioning bolt 43 is threadedly connected to the screw hole 44.

[0021] The limit strip 41 can make the rotor 3 and the input shaft 1 always rotate synchronously, thus realizing the stable transmission of power. By loosening the first positioning bolt 43, the rotor 3 can be removed from the input shaft 1, which is convenient for replacing the rotor 3 when it is damaged. At the same time, the first positioning bolt 43 can realize the rapid installation of the rotor 3. The whole process can realize the rapid disassembly and assembly of the rotor 3, greatly reducing the maintenance cost of the rotor 3.

[0022] Among them, the second connection component 6 includes a docking block 61, the docking block 61 is fixedly connected to the end of the output shaft 5, both ends of the docking block 61 are fixedly connected with a chuck 62, one side of the turbine 7 is fixedly connected with a docking seat 63 that rotates in cooperation with the docking block 61, a positioning member 65 for fixing the chuck 62 and the docking seat 63 is arranged inside the docking seat 63, clamping grooves 64 matching the chucks 62 are formed at both ends of the docking seat 63, and the chucks 62 are slidably matched with the clamping grooves 64. By quickly docking the docking seat 63 with the docking block 61 and then using the positioning member 65 to fix the chuck 62 and the docking seat 63, the installation of the turbine 7 is realized, and at the same time, the disassembly of the turbine 7 can also be realized, so that the replacement of the turbine 7 can be realized to reduce the maintenance cost.

[0023] Among them, the positioning member 65 includes two stoppers 651, the two stoppers 651 are respectively fixedly connected to both ends inside the docking seat 63, the two chucks 62 can be rotated to abut against the corresponding stoppers 651, and positioning bolts II 652 are threadedly connected to both ends outside the docking seat 63, and the threaded sections of the two positioning bolts II 652 are threadedly connected to the corresponding chucks 62.

[0025] The first gear 22 is driven to rotate by the input shaft 1, and then the third gear 24 and the fourth gear 25 are driven to rotate synchronously, which causes the second gear 23 to rotate. Since the number of teeth of the first gear 22 is greater than that of the second gear 23, the rotation speed of the first gear 22 is less than that of the second gear 23, so that the rotation speed of the input shaft 1 is less than that of the output shaft 5, and thus the differential process is realized.
