The invention relates to a synchronous regulating device of a high-speed centrifugal fan outlet guide vane, and the synchronous regulating device comprises guide vanes, wherein the shaft necks of the guide vanes are respectively installed on first axle holes which are uniformly distributed on the flange of a gear case so as to form a first revolute pair. The synchronous regulating device is characterized in that each rotating arm is respectively fixedly connected with the shaft neck of each guide vane; one ends of connecting rods are respectively connected with the rotating arms so as to form a second revolute pair, and the other ends of the connecting rods are respectively connected with axle holes which are uniformly distributed on a turntable so as to form a third revolute pair; the shaft necks of idler wheels are respectively installed on second axle holes which are uniformly distributed on the flange of the gear case so as to form a fourth revolute pair, and the inner diameter of the turntable is respectively tangent to each idler wheel so as to form a fifth revolute pair; and a total rotating arm is fixedly connected with the shaft neck of any guide vane through a second key. The synchronous regulating device provided by the invention has the advantages of simple, compact and reasonable structure, low manufacturing cost and suitability for being used on high-speed centrifugal fans of various specifications.
Description
