[0033] See Figures 1-10, an embodiment of the present utility model provides a high-torque drive device. The high-torque drive device includes a housing 1, a drive mechanism 2, a transmission mechanism, a first output shaft 4, and a second output shaft 5; the transmission mechanism is disposed within the housing 1, the first output shaft 4 is respectively connected to the transmission mechanism and the drive mechanism 2, and the second output shaft 5 is respectively connected to the transmission mechanism and the housing 1; the outer diameter of the second output shaft 5 is greater than the outer diameter of the first output shaft 4.

[0035] The technical effects that the high-torque drive device can achieve are as follows:

[0036] The drive mechanism 2 and the first output shaft 4 output a first torque, and the transmission mechanism and the second output shaft 5 output a second torque. The second torque is greater than the first torque. By means of the drive mechanism 2 and the transmission mechanism, the effect of increasing the torque is achieved, and the transmission mechanism and the second output can be changed according to the usage scenario to achieve the diversity of the second torque.

[0037] Continue to refer to Figures 1-10 , in this embodiment, the transmission mechanism includes a first gear carrier 31, a first planetary gear 32, and a sun gear 33.

The second planetary gear 35 surrounds the gear shaft, and the first ring gear 11 surrounds the second planetary gear 35, enabling the second planetary gear 35 to mesh with the first ring gear 11 and the second ring gear 311 respectively.

The second gear carrier 34 is provided with multiple protrusions, and the second planetary gear 35 is sleeved on the protrusions.

A secondary reduction structure is formed by the second gear carrier 34, the second planetary gear 35, and the second ring gear 311 to further reduce the speed on the basis of the primary reduction structure, using the speed converter of the gears to reduce the rotation speed of the first gear carrier 31 to the desired rotation speed and obtaining a larger torque.

[0041] Further, a gasket 6 is further included, and the gasket 6 is connected to the first gear carrier 31.

[0042] Specifically, the gasket 6 is located below the first planetary gear 32, separating the first planetary gear 32 from the driving mechanism 2 through the gasket 6 to prevent the first planetary gear 32 from falling off and protecting the components inside the transmission mechanism.

[0043] Further, it also includes a bearing 7. A end cover 8 is provided at the top of the housing 1. The bearing 7 is arranged on the end cover 8, and the second output shaft 5 passes through the bearing 7.
