    • A variator device (1) for the mechanical transmission of motion between two shafts (2, 3), respectively a driving shaft and a driven shaft, with a continuously variable ratio, comprises a belt (4) closed to form a loop and having a trapezoidal cross-section, and a pair of pulleys (5, 6) around which the belt (4) is wound. At least a first pulley (5) of the pair has two conical shells (5a, 5b) mounted on the driving shaft (2) with the vertices opposite each other, delimiting a groove (7) in which the belt (4) is housed at a variable distance from the axis (2a, 3a) of rotation of the shafts (2, 3). Both of the conical shells (5a, 5b) of the first pulley (5) can move longitudinally relative to the axis (2a) of rotation of the driving shaft (2). Actuator means (8; 12) are connected to each of the shells (5a, 5b) to control their movement relative to each other and to vary the distance between them so as to correspondingly vary the diameter of the belt (4) wound around the first pulley (5).
    • 用于在两个轴(2,3)(分别具有连续可变比率)的驱动轴和从动轴之间的运动的机械传动的变速装置(1)包括封闭的带(4)以形成环并具有 梯形横截面,以及一对皮带轮(5,6),所述带(4)绕其周围缠绕。 该对的至少第一滑轮(5)具有安装在驱动轴(2)上的顶点彼此相对的两个圆锥形壳体(5a,5b),限定了容纳带(4)的凹槽(7) 与轴(2,3)的旋转轴线(2a,3a)可变的距离。 第一滑轮(5)的锥形壳体(5a,5b)可相对于驱动轴(2)的旋转轴线(2a)纵向运动。 致动器装置(8; 12)连接到每个壳体(5a,5b),以控制它们相对于彼此的运动并且改变它们之间的距离,以便相应地改变缠绕在其上的带(4)的直径 第一滑轮(5)。
