Abstract
The utility model provides a blade feathering device of a wind-mill generating set, comprising a driving motor, a holding frame, a fastening wheel, a tooth belt and a blade prolonging joint with gear teeth. The fastening wheel and the driving motor are arranged on the holding frame which is arranged on a wheel hub, and both ends of the tooth belt are fixed on the blade prolonging joint and are engaged with the gear teeth on the blade prolonging joint. When the blade changing device of a wind-mill generating set changes blades, motive power provided the driving motor is transmitted on the tooth belt which are strained by two fastening wheels. The blade prolonging joint and the blades are connected with the outer ring of a blade changing bearing, and the wheel hub is connected with the inner ring of the blade bearing; in this way, the purpose that the blades are changed is accomplished. The blade changing device of a wind-mill generating set is convenient for moderating impact coming from the blades, and has the features of accurate transmission, simple structure, low cost, convenient replacement and maintenance, etc.
Description
Technical field
The invention belongs to the wind energy conversion system field, relate in particular to a kind of wind generator set blade vane change device.
Background technique
In CN02281095.1, a kind of variable speed constant frequency wind-powered electricity generation set pitch control is disclosed apart from device, its formation comprises eccentric disc, joint shaft bearing, connecting rod, pushing shaft, floating bearing, wheel hub, synchronous disk, guide rod, infer bar, promote bearing, promote oil cylinder, the blade flange plate, wind wheel main shaft and key etc., two promote the both sides that oil cylinder is installed in the wind wheel main shaft, and one end be connected with the outer shroud that promotes bearing, and the interior ring that promotes bearing is connected with catch bar, the interior ring that promotes bearing is fixed with key, rotate with main shaft, and on the wind wheel main shaft, move, the other end of catch bar is connected by bolt with synchronous disk, synchronous disk is installed on the guide rod, and on guide rod, move, the guide rod secure fit is on wheel hub, wind wheel front-end of spindle flange plate is connected with wheel hub, pushing shaft one end is fixed on the synchronous disk, the other end is contained in the tie rod holes, the other end endoporus of connecting rod is connected with joint shaft bearing, and the other end of joint shaft bearing is connected with the eccentric disc endoporus, and the floating bearing that blade is installed is fixed on the wheel hub.Though this device has advantages such as stable drive, driving torque are big, but still exist leakage, the manufacture cost height of oil, shortcoming such as change, difficult in maintenance.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model provides a kind of wind generator set blade vane change device.
This device comprises that drive motor, retainer, wheel hub and blade prolong joint, have wheel tooth on the blade prolongation joint, drive motor is installed on the retainer, and retainer is installed on the wheel hub, the toothed belt two ends are fixed on blade and prolong on the joint, and mesh with the profile of tooth tooth that prolongs on the joint.
Said apparatus can also be installed the both sides of two Idle wheels at toothed belt on retainer.When pitch-controlled system is implemented to become oar, provide motive force to be transferred on the toothed belt by drive motor, toothed belt is by two fastening wheel tensionings, the two ends of toothed belt are fixed on blade and prolong on the joint, crossing bolt because of blade prolongation joint with blade pass is connected with the pitch variable bearings outer ring, wheel hub is connected with the pitch variable bearings inner ring, can realize becoming the purpose of oar like this.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
With reference to Fig. 1, embodiment of the present utility model comprises that the blade of drive motor 4, retainer 3, fastening wheel 2, toothed belt 5 and gear teeth prolongs joint 1.Two fastening wheels 2 and drive motor 4 are installed on the retainer 3, and retainer 3 is installed on the wheel hub 6, and toothed belt 5 two ends are fixed on blade and prolong on the joint 1, and prolong profile of tooth tooth engagement on the joint with blade.When pitch-controlled system is implemented to become oar, provide motive force to be transferred on the toothed belt 5 by drive motor 4, toothed belt 5 is by two fastening wheel 2 tensionings, the two ends of toothed belt 5 are fixed on blade and prolong on the joint 1, crossing bolt because of prolongation joint 1 with blade pass is connected with the pitch variable bearings outer ring, wheel hub 6 is connected with the pitch variable bearings inner ring, can realize becoming the purpose of oar like this.
For the ease of the impact of mitigation, and realize accurate transmission, so we partly adopt the transmission of toothed belt at vane drive from blade.That this device has is simple in structure, low cost of manufacture, replacing and characteristics such as easy to maintenance.
