High-torque gear drive device

The invention discloses a high-torque gear drive device. The high-torque gear drive device comprises an input shaft, a first horizontal shaft connected with the input shaft, a second horizontal shaft connected with the first horizontal shaft through a first gear and a second gear, and a third horizontal shaft connected with the second horizontal shaft. The first gear and the second gear are installed on the second horizontal shaft and are herringbone gears with opposite spiral directions. Double split flow of torque can be achieved through the two herringbone gears with the different spiral directions, and the maximum drive torque of the gear drive device is increased. 本发明公开了种大扭矩齿轮传动装置，包括箱体，还包括：输入轴；与输入轴相连的第水平轴；与第水平轴通过第齿轮及第二齿轮相连的第二水平轴，第齿轮及第二齿轮安装在第二水平轴上，第齿轮与第二齿轮为螺旋方向相反的人字齿轮；与第二水平轴连接的第三水平轴。通过两螺旋方向不同的人字齿轮，可实现扭矩的双分流，提高了齿轮传动装置的最大传动扭矩。
