    摘要： A continuously variable transmission unit includes a disc drivingly connected to a first shaft, the disc having a frusto-conical groove in its outer periphery, the walls of the groove being inclined inwardly towards one another; an annular element is mounted for rotation about the disc, so that the inner periphery of the annular element is located within the groove, opposite faces of the annular element engaging the opposed walls of the groove. A connection is provided for transmitting rotation of the annular element to an output shaft and the annular element is mounted for rotation on a carrier, the carrier being adjustable radially of the disc to alter the eccentricity of the annular element with respect to the disc and to change the drive ratio of the transmission. The transmission unit may drive suitable gear trains to extend the range of drive ratios thereof. Positive drive elements may be included between the disc and annular element.

    摘要： A spring washer engaged transmission wherein a plurality of planetary discs are conformed to provide two opposed conical surfaces, the axis of rotation of each disc including the apex of the cone. The planetary discs are received between a first set of two dished washers forming a sun and a second set of similarly shaped washers forming an exterior peripheral ring. Each disc is mounted for rotation on a corresponding pin, the pins being received in cam grooves formed in the driving plate in a first embodiment and being mounted for eccentric rotation in the second embodiment. A centrifugal bob weight attached to each pin in the second embodiment controls the eccentric alignment of the pin thus controlling the displacement of the disc relative the first and second set of dished washers.

    摘要翻译： 一种弹簧垫圈接合传动装置，其中多个行星盘被配合以提供两个相对的锥形表面，每个盘的旋转轴线包括锥体的顶点。 行星盘被容纳在形成太阳的第一组两个碟形垫圈和形成外围环的第二组相似形状的垫圈之间。 每个盘被安装成在相应的销上旋转，在第一实施例中，销被容纳在形成在驱动板中的凸轮槽中，并且在第二实施例中安装成用于偏心旋转。 在第二实施例中，附接到每个销的离心锤重量控制销的偏心对准，从而控制盘相对于第一组和第二组碟形垫圈的位移。
