    • The invention relates to a harmonic drive (12) which can be provided with overload protection that is easy to influence constructionally and a free-wheeling characteristic. To this end, the spokes (21) of the internal geared wheel (15) are specifically deformable depending on the torque or the direction of rotation. The spoke shafts (22) are divided crosswise to the drive axis (24) or in a radial direction in relation thereto. This division (45) is bridged over flexibly in the peripheral direction of the internal geared wheel so that the effective radial length of the spoke may be reduced in the presence of the appropriate bending stress by buckling the shaft, in order to then eliminate the local toothing contact between the internal geared wheel edges (13) and the outer support ring (11) in the extension of the spoke. The bridging of the spoke division can be configured differently for the two directions of rotation in order to obtain different response characteristics, up to direction-dependent free-wheeling characteristics e.g. in the event of a considerably unsymmetrical spoke shaft course in relation to the radials.
    • 本发明涉及一种谐波驱动器(12),其可以设置有易于在结构上影响的过载保护和续流特性。 为此,内齿轮(15)的轮辐(21)可根据转矩或旋转方向而具体变形。 辐条轴(22)与驱动轴线(24)相交或相对于径向方向分开。 该分割器45在内部齿轮的圆周方向上被柔性地桥接,从而通过使轴弯曲而在存在适当的弯曲应力的情况下可以减小轮辐的有效径向长度,从而消除局部 在轮辐的延伸部分内部齿轮轮缘(13)和外支撑环(11)之间的齿接触。 轮辐分段的桥接可以针对两个旋转方向不同地配置,以便获得不同的响应特性,直到取决于方向的续流特性,例如。 在与径向相关的轮辐轴相当不对称的情况下。
