驱动机构驱动每个行星齿轮24沿对应的第一销轴25旋转，由于内齿圈21固定，在行星齿轮24与内齿圈21处于啮合状态下，每个行星齿轮24沿内齿圈21运动，从而带动行星架22旋转，行星架22与中间齿轮23固定，从而中间齿轮23旋转，而中间齿轮23与输出齿轮3啮合，进而实现输出齿轮3环绕输出轴4的轴向旋转，而输出齿轮3与输出轴4位置固定，输出齿轮3旋转带动输出轴4一同旋转，使得输出轴4可以驱动其它产品(例如，其它产品为阀门之类的被控制端)。The driving mechanism drives each planetary gear 24 to rotate along the corresponding first pin shaft 25. Since the ring gear 21 is fixed, when the planetary gear 24 and the ring gear 21 are in meshing state, each planet gear 24 moves along the ring gear 21 , Thereby driving the planet carrier 22 to rotate, the planet carrier 22 and the intermediate gear 23 are fixed, so that the intermediate gear 23 rotates, and the intermediate gear 23 meshes with the output gear 3, thereby realizing the axial rotation of the output gear 3 around the output shaft 4, and the output gear 3 and the output shaft 4 are fixed in position, and the rotation of the output gear 3 drives the output shaft 4 to rotate together, so that the output shaft 4 can drive other products (for example, other products are controlled ends such as valves).
