Abstract

A gearing has on its driving shaft a drive means carrier member carrying drive means in the form of pins protruding towards a driven means carrier member fixed to the driven shaft and carrying divergently arranged driven means. The driven shaft is offset relative to the driving shaft so that the circular orbital path of movement of the driven means surrounds the circular orbital path of movement of the driven means. From the drive means always only one single drive means contacts a driven means and only in a portion of the orbital path thereof which portion is more remote from the axis of the driven shaft than that portion of this orbital path arranged nearer to the driven shaft. In the other portions of their orbital path, the drive means pass within the orbital path of the driven means but do not contact these. This results in an increased torque of the driven shaft. Generally the speed of revolution of the driven shaft is not uniform but can be made uniform and equalized to the speed of revolution of the driving shaft by using an additional drive means, for example a belt drive means, for the driven means carrier member.
