    • Elastic deformation of bridge portions in an externally toothed gear and external teeth is suppressed, and this extends the life of tooth surfaces of external teeth 19, improves vibration characteristics, and markedly increases output torque while preventing a planetary gear device 11 from becoming large in size. To achieve the above, a ratio obtained by dividing the diameter D of each of pins constituting internal teeth 14 by the pitch P of the internal teeth 14 is made smaller to an extent where tooth tops 19a of the external teeth 19 are radially outside the inner periphery 15a of an internally toothed gear 15. Alternatively, a meeting point C where action lines S of reaction force K of drive force components meet is moved more radially outward compared with a known eccentric oscillating-type planetary gear device so as to be positioned between a pin circle P passing the centers of all the internal teeth (pins) 14 and an outer end passing circle G passing radially outer ends of through holes 22. In addition, the amount H of eccentricity of an externally toothed gear 18 relative to an internally toothed gear is set not less than 0.5 times the radius R of the internal teeth (pins) 14.
    • 抑制外齿齿轮和外齿的桥接部的弹性变形,延长外齿19的齿面的寿命,提高振动特性,显着提高输出转矩,同时防止行星齿轮装置11尺寸变大 。 为了实现上述目的,通过将构成内齿14的每个销的直径D除以内齿14的间距P而获得的比例被减小到外齿19的齿顶部19a径向地位于 内齿齿轮15的内周15a。 或者,与已知的偏心摆动型行星齿轮装置相比,驱动力分量的反作用力K的动作线S相遇的会合点C比已知的偏心摆动型行星齿轮装置更向径向向外移动,以便位于通过所有中心的销圈P之间 内齿(销)14和外通过圆G通过通孔22的径向外端。 此外,外齿齿轮18相对于内齿轮的偏心量H设定为不小于内齿(销)14的半径R的0.5倍。
