Abstract: A geared disk driven by a repositionable drive gear, with two independent and concurrent axes of rotation; both axes rotating and orbiting on one plane, about the transmission's central axis. The first axis of rotation being the gear's center. The second user-actuated axis of rotation concurrently varying its motive pivot point between the disk's center and edge, while concentrically transversing around the disk, to infinitely variably swing the disk gear. This variable swing motion is mechanically extracted and cycled through the transmission to progressively compound the combined motions to modify and sustain user-selected, infinitely variable, output speeds. Two interconnecting, clutch-free, geared-neutral, bidirectional, output mechanisms are included; one integrated within the transmission, and one separated from the transmission, to produce a continuously engaged, all-geared, complete range of transmission functions.

Abstract: The principle of the Coronel Effect resulting from an individual gear simultaneously producing two individually controllable driving functions motivating a second engaged driven gear is described. This principle is incorporated within the Coronel Effect Positively Infinitely Variable (CEPIV) transmission, a true all-geared torque converting positively infinitely variable rotary motion transmission incorporating a user-actuated independent input control to continuously infinitely varies the transmission output between a geared-neutral configuration and full-speed output. The input control varys the tilt angle of a CE drive gear to vary: (1) the degree of CE drive gear circumrevolving production of the Coronel effect counterrotation of an engaged output receiving gear, and (2) the extent of output receiving gear orbiting of the mechanism central axis. The concurrent rotational speed of the CE drive gear is utilized to neutralize the Coronel effect and produce the geared-neutral configuration.
