Description
Technical field:
The utility model relates to wind turbine equipment technical field, especially relates to a kind of wind-driven generator and becomes paddle wheel hub.
Background technique:
Existing below 5KW adopts the small-sized wind power generator of horizontal axis structure, its generator shaft is parallel to wind direction, have the blade of some wind-driven generators to starch square angle to immobilize, this structure is simple, if but wind power plant was not fallen when wind-force is larger generator blade will be made to damage, also some products are had to have employed the lateral deviation tail gear using wind wheel blade to depart from prevailing wind direction, this device is merely able to make the low-angle offset direction of blade, this device also can make generator blade damage after wind speed exceedes certain scope, utility model patent 200420062921.2 discloses a kind of blade slurry square angle automatic regulating apparatus of small-sized wind power generator, which employs the side that sharf one end is fixed on width of blade direction, the other end and one spacing, returning device controls in best effort angle and rotates at most about 90 degree within the scope of this with the wind, which raises the wind loading rating of wind-driven generator, relatively be applicable to the ability of impact fitful wind, but what adopt due to it is this mechanism of recoil of spring, this effect when wind-force is little is not too obvious, also the wind-driven generator had adopts a direct current generator to drive multiple blade to rotate by gear-driven mode simultaneously, this complex structure, Installation and Debugging are inconvenient.
Summary of the invention:
The utility model provides a kind of wind-driven generator to become paddle wheel hub, thus efficiently solve the problems of the prior art.
The utility model solves the scheme that its technical problem adopts: described a kind of wind-driven generator becomes paddle wheel hub, be characterized in comprising wheel hub compostle member, described wheel hub compostle member periphery is provided with blade support circle, be provided with between wheel hub compostle member and blade support circle and organize blade and strut more, described wheel hub compostle member comprises axial fan hub, axial fan hub center is provided with motor, motor shaft is installed with central gear by the first nut, axial fan hub is also provided with multiple second bevel gear, second bevel gear shaft is provided with the 3rd spur gear engaged with central gear, multiple first bevel gear respectively corresponding being meshed with the second bevel gear is arranged, the axle of multiple first bevel gear the inner that corresponding and blade stretches into axial fan hub is respectively connected, clutch shaft bearing is provided with in 3rd spur gear, clutch shaft bearing is fixed on axial fan hub by connecting bolt and the second nut.
Be provided with the second bearing between the first described bevel gear and axial fan hub, the second described bevel gear is connected with the 3rd spur gear elastic conjunction, and the overcoat of the 3rd spur gear and clutch shaft bearing is equipped with.
Described central gear is fixed on motor by the boss on motor shaft and the first nut, and motor is secured together by screw and axial fan hub.
By technique scheme, there is following effect in the utility model: described a kind of wind-driven generator becomes paddle wheel hub, and it can directly be installed on various middle-size and small-size wind-driven generator, can automatic stabilisation rotating speed during operation.Middle-size and small-size wind-driven generator ensures that generator speed is stablized, due to when high wind after mixing this automatic change paddle wheel hub, blade windward side reduces, this just reduces the stamping press of high wind to blade greatly, can reduce the materials consumption of blade and pylon, reduce costs during manufacture.It is reliable and stable, and expansion is convenient, is especially applicable to wind-driven generator and uses.
