Abstract
The present invention provides a variable-speed speed-up gear including an electric driving device () that generates a rotational driving force, and a planetary gear transmission device () that changes the speed of the rotational driving force generated by the electric driving device () and transmit the changed rotation driving force to a driving target, wherein a sun gear shaft () forms an output shaft (Ao) connected to the driving target, an internal gear carrier shaft () configures a constant-speed input shaft (Ac), and a planetary gear carrier shaft () configures a variable-speed input shaft (Av), the electric driving device () includes a constant-speed motor () having a constant-speed rotor () which is configured to rotate a constant-speed input shaft of the transmission device, and a variable-speed motor () having a variable-speed rotor () which is configured to rotate the variable-speed input shaft of the transmission device, the variable-speed rotor () and the planetary gear carrier shaft () have a shaft insertion hole () which is formed in a cylindrical shape around the axis and passes therethrough in the axial direction, and the constant-speed rotor () is inserted through the shaft insertion hole () and has an inertia body () which is configured to rotate in conjunction with the output shaft (Ao).
