[0028] The reducer 3 is detachably connected to the third mounting area 13; it should be noted that the structure of the reducer 3 is prior art and will not be described in detail here.
[0029] The coupling unit 4 is detachably connected to the second mounting area 12; the output end of the variable frequency motor 2 is connected to the input end of the reducer 3 through the coupling unit 4.
[0030] Specifically, such as Figures 2-4 As shown, the coupling unit 4 includes a connecting shaft 41, on which a flywheel 42 is connected. The connecting shaft 41 has a connecting protrusion 411, and the middle connecting hole of the flywheel 42 connects to the connecting protrusion 411. The connecting shaft 41 also has a limiting protrusion 412, located at one end of the connecting protrusion 411, serving as a limiting point for the flywheel 42. The limiting protrusion 412, the connecting protrusion 411, and the connecting shaft 41 are integrally formed, facilitating processing. The left side of the connecting shaft 41... Bearing seats 43 are movably connected to both ends of the right side, and the bearing seats 43 are connected to the second mounting area 12; the flywheel 42 can rotate relative to the drive base 1 through the bearing seats 43; one end of the connecting shaft 41 is connected to the output end of the variable frequency motor 2 through the coupling 44, and the other end of the connecting shaft 41 is connected to the input end of the reducer 3 through the coupling 44; the coupling 44 is a serpentine spring coupling, and its structure is existing technology, so it will not be described in detail here; the structure of the bearing seats 43 is existing technology, so it will not be described in detail here.
[0031] Furthermore, such as Figure 2 As shown, in order to facilitate the installation of the coupling unit 4, a clearance space 121 is provided on the second installation area 12. The clearance space 121 is used to make room for the flywheel 42 after installation, so that the flywheel 42 has better balance during rotation.
