VARIABLE-SPEED SPEED INCREASER, VARIABLE-SPEED SPEED-INCREASER CONTROL DEVICE, AND VARIABLE-SPEED SPEED-INCREASER CONTROL METHOD

摘要

A variable-speed speed increaser equipped with an electric drive device for producing a rotary drive force, and a planetary gear transmission device for changing the speed of the rotary drive force produced by the electric drive device, and transmitting the same to a drive target, wherein: the sun gear shaft is the output shaft connected to the drive target, the internal gear carrier shaft is a constant-speed input shaft, and the planetary gear carrier shaft is a variable-speed input shaft; the electric drive device has a constant speed motor having a constant speed rotor for rotating the constant-speed input shaft of the transmission device, and a variable speed motor having a variable speed rotor connected to the variable-speed input shaft of the transmission device; the internal gear carrier is provided with a clutch mechanism for connecting the internal gear carrier shaft and a cylindrical part connected to the internal gear; and the clutch mechanism has a moving part connected to one element among the cylindrical part and the internal gear carrier shaft so as to be capable of moving in the axial direction, a drive unit for driving the moving part in the axial direction, a secured part that is secured to the other element among the cylindrical part and the internal gear carrier shaft, and an engaging part which engages the moving part and the secured part in association with the movement in the axial direction by the moving part.
