    • Provided is a planetary gear reducer including: a sun gear fixed concentrically to a power input shaft; a plurality of planet gears meshing with the sun gear; a ring gear meshing with the planet gears; a planet carrier configured to support a plurality of planet shafts, each of which is a rotational axis of a corresponding one of the planet gear, and to output revolution of the plurality of planet gears as first power; and a cylindrical support connected to the ring gear, non-rotatable relative to the ring gear, and configured to output rotation of the ring gear as second power. The cylindrical support includes, at one part along the direction of a central axis, a flexible structure which is curved radially inward and has a V-shaped longitudinal section. This configuration improves rigidity and prevents misalignment without increasing the weight of the gear reducer.
    • 提供一种行星齿轮减速器,其包括:与动力输入轴同心地固定的太阳齿轮; 与太阳齿轮啮合的多个行星齿轮; 与行星齿轮啮合的齿圈; 行星架,其被配置为支撑多个行星轴,每个行星轴是行星齿轮的相应一个的旋转轴线,并且输出多个行星齿轮的转数作为第一功率; 以及连接到所述齿圈的圆柱形支撑件,其相对于所述齿圈不能旋转,并且被配置为输出所述齿圈的旋转作为第二动力。 圆柱形支撑件在沿着中心轴线的方向的一部分上包括径向向内弯曲且具有V形纵向截面的柔性结构。 这种结构提高了刚性并且防止了不对准而不增加齿轮减速器的重量。
