    摘要： A mechanism for synchronously varying pitch of a multi-blade rotor, such as rotors used in wind or hydraulic generator and helicopter is provided in the present invention. The sync-pitch-varying mechanism for the rotor mainly comprises a bearing a driver, a transmission, a linkage and a control unit, wherein the transmission includes a shaft coupling, a ballscrew, an intermediate cylinder, a driven shaft and a transition cylinder; the linkage includes a link hub, a guide support and multiple links; the control unit includes a speed sensor, a position sensor, a switch and a programmable controller; a rotatory driving force output by said driver through the shaft coupling is transmitted to the driven shaft through a screw-and-nut transmission between the ballscrew and the intermediate cylinder of the transmission so as to drive the driven shaft to move in a linear motion which is then transferred from the driven shaft to the link hub of the linkage through means of the transition cylinder; the controller is configured to enable the driven shaft to move reciprocally within a predefined range of length in order to move the link hub back and forth along the guide support in an axial direction thereof, and therefore multiple bearings for supporting the blades of the rotor are rotatably movable through the multiple links of the link hub. Advantageously, the mechanism of the invention has a simple and compact structure, low cost and high reliability, and the operation is easy to be controlled precisely.
