Abstract: The invention relates to a gear transmission with a steplessly adjustable translation ratio for converting of rotary speeds and of torques of shafts. The uniform rotary motion of a drive shaft is transferred to a driven shaft with the aid of time staggered operating gear transmission units. The rotary motion is transformed by a cam transmission initially into a uniform translational motion and in the following this uniform translational motion is transformed into another, also uniform translational motion, with a speed depending on the translation ratio setting with a translation device. Finally this translational motion is transferred again into a uniform rotary motion by a further planar cam transmission and transferred to the driven shaft.
