The gearbox (29) comprises an annular support (31) on which pairs of gears (33A-33J) for inputting motion to the gearbox are rotatably supported. Each pair of gears comprises a first gear (35) and a second gear (37) adapted to receive an input motion; the first gear and the second gear are coaxially and angularly coupled to each other for integral rotation. The gear ratio defined by each pair of gears is different from the gear ratios defined by the other pairs of gears. The annular support is angularly movable about a selection axis to selectively bring one of the gear pairs into a moved angular engaged position in the input of the gear ratio gearbox. The gearbox also includes a mechanical connection between a second gear of the pair of gears in an angular engaged position input to motion of the gear ratio gearbox and an output shaft (45) having an axis of rotation (A-A) parallel to or coincident with the selection axis, with the output shaft passing through the annular support.
齿轮箱(29)包括环形支撑件(31),用于向齿轮箱输入运动的成对齿轮(33A‑33J)可旋转地支撑在环形支撑件上。每对齿轮包括适于接收输入运动的第一齿轮(35)和第二齿轮(37);第一齿轮和第二齿轮同轴且彼此成角度地联接以一体地旋转。每对齿轮限定的传动比不同于由其它齿轮对限定的传动比。环形支撑件可围绕选择轴线成角度地移动,以选择性地使齿轮对之一进入传动比齿轮箱的输入中的运动的角度接合位置。齿轮箱还包括在成对齿轮中的第二齿轮和输出轴(45)之间的机械连接,第二齿轮处于输入到传动比齿轮箱的运动的角度接合位置,输出轴具有平行于选择轴线或与其重合的旋转轴线(A‑A),其中输出轴穿过环形支撑件内。
