Description
Technical field
The present invention relates to a kind of paddle slewing gear of variable pitch type wind driven generator, relate in particular to the synchronous slewing gear of paddle of variable pitch type wind driven generator.
Background technique
It all is to realize that by the spring of elasticity coefficient such as a pair of or a plurality of two or the multi-disc fan blade angle that facings the wind is identical that tradition becomes the oar fan blade, this kind method is selected to require very high to spring, in case it is inconsistent that elasticity coefficient is selected, each fan blade is in operation and will shakes because of uneven, and is easy to generate the inconsistent problem in angle down with the wind.In actual the use, it is a lot of to cause each paddle factor that angle differs of facining the wind, even spring is selected to adhere to specification, the last lower deviation of the friction factor of each paddle rotary part, wind direction can cause that all the paddle angle of facining the wind differs, balance is poor when causing running, appearance is shaken, the unbalance loading wear problems, influences the working life of product.
Summary of the invention
The present invention is directed to above problem, a kind of angle unanimity of facining the wind of each paddle can guarantee to turn round the time is provided, running is steadily avoided the defective that turns round, thereby prolongs the paddle Equilibrator of the variable pitch type wind driven generator in complete machine working life.
Technological scheme of the present invention is: it comprises flange, be connected and can change some fan blades, fan blade and the flange connection part of angle down with the wind on the flange and be provided with and be used for stablize the facing the wind spring of angle of fan blade, and it also comprises some covers of being disposed radially with the rotating disk of concentric settings of flange, at the flange periphery, be arranged on fan blade angle adjustment spool in the cover, be connected the connecting rod of rotating disk and fan blade angle adjustment spool; The flange middle part is provided with cavity, and being provided with one in the cavity can be with respect to the rotating disk of flange rotation; Some covers are fixedlyed connected with flange, and fan blade angle adjustment axle is located in the cover, are connected by the shape of threads curvilinear groove with cover; Described spring is arranged on fan blade angle and adjusts between axle and the cover; Fan blade is fixedlyed connected with the outer end that fan blade angle is adjusted axle, is connected with connecting rod at fan blade angle adjustment axle towards an end of flange center, and the other end of connecting rod connects rotating disk.
Be connected to bulb bindiny mechanism between described connecting rod and the fan blade angle adjustment axle.
The described step hole that is arranged with, fan blade angle adjustment axle are provided with multistage step circle.
Between fan blade and flange, also be provided with the startup spring.
In this device center one coaxial rotating disk is arranged, ball-head tension rod is equipped with on the rotating disk both sides, and the bulb end of ball-head tension rod is connected on the fan blade connecting rod.Spring housing and flange weld together, and curvilinear groove is arranged in spring housing, and the fan blade connecting rod utilizes curvilinear groove to drive the fan blade rotation, realizes the change of angle down with the wind.In the spring housing hierarchic structure, in the two-stage spring is arranged, the elastic force that starts spring is very little, fan blade just is easy to from the optimum start-up angle change to the best effort angle, and the elastic force of spring is bigger, be used to keep fan blade and facing the wind the angle at best angle, the angle that only facings the wind when wind speed is excessive just can continue to reduce to reduce rotating speed.Washer and snap ring are used for two springs are located.When wind speed surpassed work wind speed, fan blade rotates the centrifugal force that produces will be greater than spring force, thereby the fan blade connecting rod is turned an angle along curvilinear groove, and the windward side is increased, and rotating speed reduces.After rotating speed reduced, centrifugal force and spring force reached balance again, and fan blade can remain the best angle that facings the wind, and can guarantee that rotating speed is no more than rated speed.The present invention is simplified change oar fan blade manufacturing process, and has improved the stability of a system.
Used blade to facing the wind among the present invention linking mechanism that angle changes makes two or the multi-disc fan blade can guarantee same axial stretching amount and the angle that facings the wind, even the spring attribute that each fan blade is selected for use is not quite identical, also can reach the effect that makes fan blade synchronous.Because the moving direction of rotating disk and fan blade connecting rod is different,, has reduced technology difficulty and improved reliability so used ball-head tension rod to connect two parts.Processed curvilinear groove at the spring housing inwall, the fan blade connecting rod can move along curvilinear groove and realize the change at angle down with the wind when centrifugal force and elastic force were uneven like this.
