Variable speed step-up gear, control device for variable speed step-up gear, and control method for variable speed step-up gear

摘要

An electric device that generates a rotational driving force, and a planetary gear transmission that shifts the rotational driving force generated by the electric device and transmits the rotational driving force to a driving target, and an output shaft to which the sun gear shaft is connected to the driving target is formed. The internal gear carrier shaft forms a constant speed input shaft, the planetary gear carrier shaft forms a variable speed input shaft, and the electric device includes a constant speed motor having a constant speed rotor that rotates the constant speed input shaft of the transmission. A variable speed motor having a variable speed rotor connected to a variable speed input shaft of the transmission, and the internal gear carrier is a clutch that connects the cylindrical portion connected to the internal gear and the internal gear carrier shaft The clutch mechanism includes a moving part connected to one of the cylindrical part and the internal gear carrier shaft so as to be movable in the axial direction, a driving part for driving the moving part in the axial direction, a cylindrical part, and an internal gear Fixed to the other side of the carrier shaft When, by the moving unit moves in the axial direction, the moving portion and the engaging portion to a fixing portion engaged, variable-speed gearbox with.
