    Abstract: A device to guide an object (A) around two axes (R.sub.1 and R.sub.2).A motor (M.sub.1) controls rotation around an axis (R.sub.1) by three gears (51, 70, 71); a further motor (M.sub.2) controls the rotation of a fork joint (C) around another axis (R.sub.2) by two other gears (26, 27). It simultaneously lets run the entire first motor (M.sub.1). The gears are calculated so that the main shaft (72) of the object (A) moves around (R.sub.2), but does not then revolve around (R.sub.1).

    Abstract translation: 围绕两个轴(R1和R2)引导物体(A)的装置。 电动机(M1)通过三个齿轮(51,70,71)控制围绕轴线(R1)的旋转; 另一个电动机(M2)通过两个其他齿轮(26,27)控制叉形接头(C)围绕另一轴线(R2)的旋转。 它同时允许运行整个第一个电机(M1)。 计算齿轮使得物体(A)的主轴(72)绕(R2)移动,但不围绕(R1)旋转。
