Abstract
A gearbox apparatus comprising a base gear, output gear, center gear set, and input cam. The input cam has eccentricity to allow simultaneous gear interaction between the center gear set and the base gear, and the center gear set and the output gear. The center gear set's gear interacting with the output gear having number of teeth A. The output gear with number of teeth being B. The center gear set's gear interacting with the base gear having number of teeth C. The base gear with number of teeth being D. For gears of the same pitch the number of teeth is A−B is equal to N while C−D is also equal to N. The resultant ratio between the output gear and the input cam when the base gear is held stationary is equal a predetermined ratio of 1:(1/(A/B−C/D)).
