The invention discloses a double-speed multipurpose winch with a planetary gear train speed change mechanism. The double-speed multipurpose winch is formed by connecting the planetary gear train speed change mechanism with a gear reduction mechanism. In the speed change mechanism, the rotating speed of an inner gear ring is changed by shifting a handle to achieve high-low gear speed switching of the winch, when a connecting rod is located at the position a, a sliding block, the inner gear ring and a fixed connecting frame are regarded as the same component, the rotating speed is zero, and the winch is in a low-speed gear. When the connecting rod is located at the position b, the sliding block, the inner gear ring and the center wheel in the speed change mechanism are regarded as the same component with the same rotating speed, the transmission ratio of the speed change mechanism is 1, and the winch is in a high-speed gear. The gear reduction mechanism is composed of a small-tooth-difference planetary gear train fixed by an inner gear ring and a fixed shaft gear train or a small-tooth-difference planetary gear train fixed by a pin or a planetary gear train and a small-tooth-difference planetary gear train fixed by a pin, and an output component of the fixed shaft inner gear ring or a small-tooth-difference inner gear ring is directly connected with a winding drum externally connected to a speed reducer shell. The transmission is simple in structure, large in transmission ratio variable range and small in occupied area.
本发明公开的一种行星轮系变速机构双速多用绞车,由行星轮系变速机构连接齿轮减速机构组成。变速机构中通过拨动手柄改变内齿圈的转速实现绞车的高低两档速度切换,当连接杆处于位置a时,其中滑块、内齿圈与不动的连接架视为同一构件,转速为零绞车为低速挡;当连接杆处于位置b时,变速机构中的滑块、内齿圈和中心轮视为同一构件转速相同,此时变速机构传动比为1,绞车为高速挡。齿轮减速机构由内齿圈固定的少齿差行星轮系及定轴轮系或由柱销固定的少齿差行星轮系、或由行星轮系及柱销固定的少齿差行星轮系组成,定轴内齿圈或少齿差内齿圈输出构件与外接在减速器外壳上的卷筒直接连接。其结构简单,传动比可变范围大,占地面积小。
