A planetary gear torque apparatus comprises: a housing, a front end cover, a back end cover, an input shaft, a sun gear, a gear transmission mechanism, a rotary disc, and an output shaft. Two sides of the housing are provided with end covers. A front end cover is provided with a first shaft hole, and the input shaft passes through the first shaft hole. A back end cover is provided with a second shaft hole, and the output shaft passes through the second shaft hole. A sun gear is sleeved and fixed on the input shaft. The sun gear engages with a first planet gear. The first planet gear and a second planet gear are coaxially disposed and generate two different torques. The second planet gear engages with a gear disposed in a radial direction, increasing the torque and enabling the rotary disc to have a large torque. The rotary disc is fixed on the output shaft. A torque of the output end is larger than a torque of the input end. Since the number of gears on the first planet gear and on the second planet gear are different, a transmission ratio of a gear system can be adjusted. The present invention further increases a mechanical efficiency of the planetary gear torque apparatus, and can be applied in a vehicle power transmission device and a mechanical transmission device. |
