The invention relates to the field of speed reducers, and provides a compact type shell output built-in winch lifting gear box. A composite planetary transmission gear train comprises two or more epicyclic gear trains and an ordinary gear train to form a composite planetary gear train, a transmission shaft is connected with a sun gear of a primary planetary gear train and meshes with a primary sungear and a primary inner gear ring shell, the primary planetary carrier is connected with a sun gear of the intermediate planetary gear train, power split-flow transmission and partial torque outputare achieved, and meanwhile, meshing with a final-stage sun gear and an intermediate-stage inner gear ring shell is achieved. The final-stage planetary gear train is an ordinary gear train, the planetary carrier does not rotate and is fixedly supported on a supporting base, an inner gear ring drives a winding drum to rotate through a flange, and output is completed. The whole gear box is integrated in the winding drum, and the internal space of the winding drum is effectively utilized. Through three-stage planetary transmission, the output torque is improved.

    本发明涉及减速机领域,提供了紧凑型壳输出内藏式卷扬提升齿轮箱。复合行星传动轮系包括两个或多个周转轮系和一个定轴轮系,组成一个复合行星轮系,传动轴与初级行星轮系的太阳轮相连,同时与初级太阳轮和初级内齿圈壳体啮合,初级行星架和中级行星轮系的太阳轮相连,实现功率分流传递和部分扭矩输出,同时与末级太阳轮和中级内齿圈壳体啮合。末级行星轮系为定轴轮系,行星架不旋转,固定支撑在支撑座上,由内齿圈通过法兰带动卷筒转动,完成输出。整体齿轮箱整合在卷筒内部,有效利用了卷筒内部空间。三级行星传动,提高了输出的扭矩。
