Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0037] As Figures 1-8As shown, the motor with torque control function disclosed by the embodiment of the application comprises a motor body 1, a torque adjusting mechanism 6, an auxiliary assembly 8 and a heat dissipation assembly 9. The top of the motor body 1 is fixed with a mounting box 2. A plurality of air holes 95 are arranged through the top of the mounting box 2. The output end of the motor body 1 penetrates through the bottom of the mounting box 2 and is rotationally connected. A driving box 3 is rotationally arranged in the mounting box 2. A plurality of sliding through holes 7 are arranged through the bottom of the driving box 3. The top of the driving box 3 is fixed with a driving pipe 4 coaxially arranged with the driving box 3. The driving pipe 4 penetrates through the top of the mounting box 2 and is matched. In the process of adjusting the torque of the driving box 3, the staff only needs to adjust the rotating speed of the output end of the motor body 1 through the torque adjusting mechanism 6 to change the torque of the driving box 3 and the driving pipe 4, thereby avoiding the complicated operation of the prior art and improving the speed of torque adjustment of the device.

[0038] The torque adjusting mechanism 6 is arranged on the mounting box 2 and is used for adjusting the rotating speed of the output shaft of the motor body 1 to change the torque of the driving box 3.

The first driven wheel 613 is fixedly sleeved on the first driven rod 612 and is engaged with the first main gear 611. The first gear ring 614 is rotationally arranged on the inner bottom wall of the mounting box 2 and is engaged with the first driven wheel 613. The modulus of the first main gear 611, the modulus of the first driven wheel 613 and the modulus of the first gear ring 614 are equal. The number of teeth of the first gear ring 614 is greater than the number of teeth of the first main gear 611. The number of teeth of the first main gear 611 is greater than the number of teeth of the first driven wheel 613. The first driven wheel 613 and the first main gear 611 are located on the inner side of the first gear ring 614. In the process of rotating the output shaft of the motor body 1, the first main gear 611 fixed with the output shaft of the motor body 1, the first driven wheel 613 engaged with the first main gear 611, the first driven rod 612 connected with the first driven wheel 613 and the first gear ring 614 engaged with the first driven wheel 613 are all rotated. The first gear ring 614 is driven to rotate by the transmission assembly 63 to drive the driving box 3 to rotate. Since the number of teeth of the first gear ring 614 is greater than the number of teeth of the first main gear 611 and the number of teeth of the first main gear 611 is greater than the number of teeth of the first driven wheel 613, the rotating speed of the driving box 3 is lower than the rotating speed of the output shaft of the motor body 1, thereby achieving the purpose of increasing the torque of the driving box 3.

[0039] The second adjusting assembly 62 is used to provide another torque to the driving box 3, and the second adjusting assembly 62 comprises a second main gear 621, a second driven rod 622, a second driven wheel 623 and a second gear ring 624.

The second gear ring 624 is in mesh with the second driven wheel 623, and the number of teeth of the second gear ring 624 is equal to that of the first gear ring 614. The module of the first main gear 611, the module of the second main gear 621, the module of the second driven wheel 623 and the module of the second gear ring 624 are all equal. During the rotation of the output shaft of the motor body 1, the second main gear 621 in fixed connection with the output shaft of the motor body 1, the second driven wheel 623 in mesh with the second main gear 621, the second driven rod 622 connected with the second driven wheel 623 and the second gear ring 624 in mesh with the second driven wheel 623 are all rotated. Since the module of the first main gear 611, the module of the second main gear 621, the module of the second driven wheel 623 and the module of the second gear ring 624 are all equal, the number of teeth of the second main gear 621 is smaller than that of the first main gear 611, the number of teeth of the second driven wheel 623 is greater than that of the first driven wheel 613, and the number of teeth of the second gear ring 624 is equal to that of the first gear ring 614, so that the rotation speeds of the first gear ring 614 and the second gear ring 624 are different.

In this process, the second transmission block 634 is first raised and separated from the first transmission block 632, and finally the second transmission block 634 is connected in plug with the third transmission block 636.
