ABSTRACT:
A variable speed transmission is disclosed wherein two convergent, conical gear trains simultaneously increase in circumference such that the parallel expansion of the convergent gear trains produces a corresponding efficiency increase which constitutes a principle of operation for the generation of ratios. A Driven Shell having convergently disposed input Gears is driven by the gears such that the Driven Shell and Input Gears form the set of convergent cones.
A shifting means comprising a Shifting Control Slide is tracked to a fixed, Stabilizing Shaft disposed within a hollow, Helical Control Drum. Whereby, the Stabilizing Shaft prevents inadvertent rotational motion of the Slide, such that two Carriage Indexing Pins, integral with the Slide engage the Double Lead Helical Slots formed in the Control Drum, and being so driven by rotation of the Slots, aligns the Carriage surrounding the Control Drum such that movement in the Carriage locates a Power Engagement Mechanism via a Carriage Bearing to index the Input Gears.
An Input Power Shaft, comprising two Input Power Drums is joined via six Roller Guides. Rotation of the Input Power Shaft is translated through the Input Gears to drive the Driven Shell.
