<p>Device for providing a variable transmission ratio between an input shaft and an output shaft, wherein the device comprises a cone-shaped first revolving body (I). Also provided are coupling means for connecting the input shaft and/or the output shaft at variable positions to the surface of the cone-shaped first revolving body (I). The coupling means comprise a cylindrical second revolving body (II) in combination with a third revolving body (III) placed operatively between the first revolving body and the second revolving body. Positioning means (P) are provided for positioning the third revolving body (III) at any desired position relative to the outer surfaces of the cone-shaped first revolving body (I) and the cylindrical second revolving body (II).</p> |
