[0028] The gear box 20 is integrally arranged above the end cover 11 of the motor body 10, has good load-bearing capacity, and can run smoothly even under long-term stress. A box cover 30 is detachably arranged above the gear box 20;
[0029] A first gear assembly 40 and a second gear assembly 50 are disposed between the gear box 20 and the box cover 30. The first gear assembly 40 is connected to the gear box 20 and the box cover 30 via a rotating shaft 46 disposed inside the gear box 20, and the second gear assembly is connected to the gear box 20 and the box cover 30 via an integrated output shaft 56 disposed inside the gear box 20 and extending out of the box cover 30.
[0030] The output shaft of the motor body 10 passes through the end cover 11 and is machined in the gear box 20 to be connected with the helical teeth 12 and the first gear assembly 40 in transmission connection;
[0031] The output is transmitted through the first gear assembly 40, the second gear assembly 50 and the output shaft of the motor body 10, and a multi-stage transmission is adopted, so the transmission torque is large and the performance is better.
[0032] In this embodiment, the box cover 30 of the present application is fixed on the top of the gear box 20 by a plurality of bolts 60, which can be easily disassembled during the later maintenance process, thereby reducing the working time of the operator.
[0033] In order to ensure the sealing performance after the gear box 20 and the box cover 30 are fixed, a contoured gasket 70 is laid between the gear box 20 and the box cover 30 in the present application.
[0034] Specifically, the first gear assembly 40 of the present application includes a first gear part 41, a first bearing chamber 43 with a first bearing body 42 built in, and a second bearing chamber 45 with a second bearing body 44 built in. The first bearing chamber 43 and the second bearing chamber 45 are correspondingly formed on the bottom surface of the gear box 20 and the bottom surface of the box cover 30, and the rotating shaft 46 is inserted in the inner ring of the first bearing body 42 and the second bearing body 44.

The second gear member 51 is installed on the integrated output shaft 56 inside the gear box 20 and is meshed with the first gear member 41.
[0036] When the power shaft of the motor body 10 rotates, the bevel teeth 12 on the top thereof will drive the first gear member 41 to rotate, and the first gear member 41 will drive the second gear member 51 to rotate. At the same time, the integrated output shaft 56 will also rotate, thus realizing multi-stage transmission and increasing the transmission torque.
