A moon gear assembly is provided that includes a moon arm assembly having a driving moon gear. A pivot pin is connected to the moon arm assembly, and an adjustment arm is connected to the moon arm assembly. The moon arm assembly may also include a body that defines a chamber, a worm gear disposed in the chamber and arranged to interact with the driving moon gear, and a motor disposed in the chamber and couple to the worm gear.

The present invention relates to transmission systems and changing gear ratios within power transmission systems. In particular, the present invention relates to a positive displacement variable speed transmission. The transmission includes one or more drive gears which orbit, rotate, and which translate radially to change the size of the orbital path. The change in the orbital path increases or decreases the linear velocity of the drive gears which engage one or more driven gears and transfer the changed linear velocity in the form of a gear ratio change. The driven gears are also radially movable and movement of the driven gears is synchronized with the radial movement of the drive gears to maintain substantially constant engagement between gear ratios change. Thus, as the drive and driven gears can slide or step radially to any location within a range of positions, gear ratio changes can be made in very small increments.
