Abstract
Provided is a generator rotating-speed-stabilizing device. A main power shaft of a main power system transmits inputted power with unstable rotating speed to the driving shaft of a bevel-type continuously variable transmission (CVT) with a speed change mechanism or directly. The inputted power with unstable rotating speed is outputted by a driven shaft after subjected to speed change of the CVT. Then, after subjected to speed reduction, the power is transmitted to a generator which generates alternating current. A controller of an automatic speed regulating system always receives a driving shaft rotating speed signal transmitted from a driving shaft rotating speed sensor and a driven shaft rotating speed signal transmitted from a driven shaft rotating speed sensor and outputs a control signal to control the rotation of a speed regulating motor. The speed regulating motor adjusts the gear ratio of the bevel-type CVT with the speed change mechanism in order to make the rotating speed of the driven shaft of the CVT constant. The power is transmitted to the generator after speed change mechanism in order to make the rotating speed of the generator constant and make AC frequency constant.
