Abstract
The invention relates to a mechanical device on a high-speed centrifugal fan and used for synchronously adjusting angle of an outlet guide vane, in particular to a shifting-fork-type diffusion guide vane adjusting device which comprises N guide vanes, a main shifting fork and N-1 branched shifting forks. Shaft necks of the guide vanes are mounted in first shaft holes uniformly distributed in a gearbox flange respectively to form a first rotating pair, the main shifting fork is fixedly connected with the shaft necks of the guide vanes through an elastic pin and connected with a driving device, the other end of the main shifting fork is connected with shaft holes uniformly distributed in a shifting disc through a shifting shaft to form a second rotating pair, the N-1 branches shifting forks are fixedly connected with the shaft necks of N-1 guide vanes through elastic pins respectively, and the other ends of the branched shifting forks are connected with the shaft holes uniformly distributed in the shifting disc through the shifting shaft to form another second rotating pair. The shifting-fork-type diffusion guide vane adjusting device has the advantages of simple, compact and reasonable structure, low manufacturing cost, simple rotating stress of the guide vanes and small resistance loss.

Embodiment
Beneficial effect in order more properly to describe the present invention and to bring, is described further the present invention below in conjunction with accompanying drawing, but protection scope of the present invention is not limited to the content that embodiment is explained.
Embodiment:
A diffusion guide blade controlling device, comprises that the axle journal 11 of 1,11 stator 1 of 11 stators is installed on respectively in the first axis hole 7 uniform on gear-box flange; Form the first revolute pair;
1 main shift fork 2, main shift fork 2 is fixedly connected by resilient key 4 and the axle journal 11 of stator 1, and is connected with drive unit;
3,10 minutes shift forks 3 of 10 minutes shift forks are fixedly connected by the axle journal 11 of resilient key 4 and 10 stators 1 respectively;
The other end of main shift fork 2 is connected with axis hole 61 uniform on shifting disc 6 by shifting shaft 5, and the other end of minute shift fork 3 is connected with axis hole 61 uniform on shifting disc 6 by shifting shaft 5, jointly forms the second revolute pair;
On gear-box flange on uniform the first axis hole 7 center circle diameter D1 and shifting disc 6 center of circle of uniform axis hole 61 center circle diameter D2 on same axis.
Main shift fork 2, under motor drives, rotates along clockwise direction, and the stator being directly connected with it by resilient key 4 also rotates along clockwise direction.On the other hand, by shifting shaft 5 and 6 of the direct-connected shifting discs of main shift fork 2, can rotate along clockwise direction, shifting disc 6 drives a minute shift fork 3 to turn clockwise, thereby drives remaining stator to turn clockwise.Thereby realized the synchronization regulation to all stators, be conducive to guarantee the precision of synchronization regulation.
