A rotor of the transmission is journaled within a stationary housing and is driven by rotatable gear rack components therein. A pinion gear drives the gear rack components by sequentially meshing with spaced apart gear racks on each component. A speed selector assembly positions the pinion gear relative the rotor axis and includes a gear train to couple the gear to a power input shaft. Speed changes between the input shaft and a rotor driven output shaft are effected by positioning of the pinion gear away from the rotor axis resulting in the gear rack components moving eccentrically within the rotor. A cam structure acts on each gear rack component to control meshing of the gear racks on the component with the pinion gear. Each of the pairs of gear racks on a modified form of the transmission are resiliently mounted on their respective gear rack assemblies. Rails of each gear rack assembly rotate about stationary but adjustable cam rings of the transmission. The gear rack assemblies include bearing elements at their ends for engagement with the transmission rotor. |
