Abstract: 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.

Abstract: In one example, 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.

Abstract: Transmission systems, assemblies, and components are described. In particular, aspects of the present disclosure relate to an infinitely variable transmission that maintains constant tooth engagement during changes in gear ratio. In one aspect, a transmission includes an axially movable sheave coupled to a chain. The sheave rotates around a drive axis. At least partially within the sheave is a set of moon gears. The moon gears orbit around the drive axis and are rotatable around respective internal axis. As the sheave moves axially, the chain and the set of moon gears move radially to define different gear ratios, with the gear ratios being changeable in infinitely small increments. A synchronization system moves the set of moon gears radially to correspond to the axial position of the sheave. A correction system optionally controls rotation of the moon gears to rotate teeth of the moon gears into alignment with the chain.
