Abstract: A gear-driven repositionable variable orbital disk gear driven about its user-actuated variable circular track to induce a concurrent varying second swing motion which is isolated, extracted, and cycled through the mechanism as an additional rotational product for the production of stepless infinitely variable rotational motion output is described. The gear driven disk gear drives a planetary sun gear through a telescoping shaft to transfer rotation to a geared base unit and dual output shafts through the planetary planet gears. This generates the mechanism's low speed output. User-actuated repositioning of the disk gear away from the mechanism central axis induces concurrent disk gear swing rotation as it is driven around the central axis. This swing rotation is extracted by a variable orbital arm and transferred to infinitely variably accelerate the base unit and the dual output shafts, generating the mechanism's infinitely variable output speed increases.
