ABSTRACT:
The variable speed planetary drive of the present invention comprises a combination of a plurality of external gears of varying pitch diameters and a first power transfer gear coaxially affixed to each other and rotatably mounted on an eccentric section of a first shaft; a second power transfer gear coaxially affixed to a second shaft disposed in line with the first shaft wherein the first and second power transfer gears engage each other; and a combination of internal ring gears of varying pitch diameters coaxially affixed to each other and disposed coaxially to the first and second shaft in an axially shiftable arrangement wherein each shift engages only one of the external gears to only one of the internal ring gears. The combination of the internal ring gears includes means for restraining the internal ring gears from rotating, which means may be a permanent type or a type that can be activated and deactivated.
