    • This invention relates to reduction in frictional torque of a harmonic drive type transmission apparatus having a circular spline, a flexspline, and a wave generator. A wave generator bearing of the wave generator has a retainer for holding a number of balls which roll between the inner and outer races to be in contact with an inner race and an outer race and to be separated from each other in the circumferential direction. The ball retainer has a number of radial pockets for storing the balls. Each pocket is formed into a shape forming a narrow (in the circumferential direction) opening portion at the inner race side and a wide (in the circumferential direction) opening portion at the outer race side. The balls are in contact with the opening portion at the inner race side in the pockets at the minor axis positions of a drive cam, and the balls are in contact with substantially the central portion of the pocket inner surface at the major axis positions of the cam.
    • 本发明涉及具有圆形花键,柔性线和波发生器的谐波驱动型传动装置的摩擦转矩的减小。 波发生器的波发生器轴承具有用于保持在内圈和外座圈之间滚动以与内座圈和外座圈接触并在圆周方向上彼此分离的多个滚珠的保持器。 球保持器具有用于存放球的多个径向袋。 每个袋形成在内圈侧的狭窄(在周向)开口部分和在外圈侧的宽(在周向)开口部分上形成的形状。 滚珠与驱动凸轮的短轴位置处的凹部内圈侧的开口部接触,并且滚珠与凹部内表面的大致中心部分在主轴位置处接触 凸轮
