    • A variable steering gear mechanism (9), comprising an external gear (15) connected to an input shaft (11), an internal gear (16) fixed to a housing (10) and meshed with the external gear (15), an intermediate member (19) receiving a torque from the external gear (15), changing means (18a, 31, 33a) capable of changing the ratio of the rotational speed of an output shaft (33) to that of a guide member (18), and an Oldhdam's coupling (17) connecting the intermediate member (19) to the guide member (18), whereby the characteristics of the changing means can be effectively utilized, the amount of eccentricity of the external gear (15) can be absorbed and only the rotation thereof on its axis can be taken out and transmitted by using the Oldham's coupling (17), and a smoother power transmission is allowed since the engaged length of the external gear (15) with the internal gear (16) is increased.
    • 一种可变转向齿轮机构(9),包括连接到输入轴(11)的外齿轮(15),固定到壳体(10)并与外齿轮(15)啮合的内齿轮(16) 接收来自外齿轮(15)的扭矩的构件(19);能够改变输出轴(33)的转速与引导构件(18)的转速之比的改变装置(18a,31,3a) 以及将中间构件(19)连接到引导构件(18)的Oldhdam连接器(17),由此可以有效地利用改变装置的特性,外部齿轮(15)的偏心量可以被吸收,并且只有 由于其外齿轮(15)与内齿轮(16)的接合长度增加,因此可以通过使用奥德姆联轴器(17)将其在其轴上的旋转取出并传递,并且允许更平滑的动力传递。
