Kind Code:
B2
Abstract:
PURPOSE: To regulate the installing angle of vanes securely without necessity of using a hydraulic cylinder.
CONSTITUTION: A gear train which consists of a sun gear 21 connected to an electric motor through an input shaft 7, an epicyclic gear 22 engaged with the sun gear 21 and revolving around the periphery of the sun gear while rotating, and the third gear 24 engaged with the epicyclic gear 21, is provided. While either one side gear of the epicyclic gear 22 or the third gear 24 is connected to an output shaft 11, the other side gear is driven by a gear change device installed between a fixed shaft and a rotating main shaft, and the change gear ratio is selected to make the rotation speeds of the output shaft 11 and the rotating main shaft equal when the sun gear 21 is being stopped.
