Description
Technical field
The present invention relates to a kind of wind-driven generator, specifically a kind of Yawing mechanism that is used on the wind-driven generator.
Background technique
Wind-driven generator will realize that all wind-driven generator goes off course automatically to wind and when running into high wind automatically in the course of the work, reaching the purpose of automatic speed regulation and speed limit, thereby play wind-driven generator self-protection with automatically to wind action.In the prior art, wind-driven generator adopts huge empennage, and this huge equipment all should not use in big-and-middle-sized wind-driven generator.
Summary of the invention
The objective of the invention is to design a kind of Yawing mechanism of wind-driven generator, to improve the bearing capacity of Yawing mechanism; Reduce because frequent clockwise and anticlockwise starts the fatigue damage that causes to Yaw gearbox.
According to technological scheme provided by the invention, it on the ring-shaped brake dish pivoting support of the annular that fuses mutually, outer rim at pivoting support is provided with tooth, it is characterized in that: there is retarder the outside at pivoting support, it above the described retarder interconnective motor, the driftage driving gear of retarder and the engagement of the tooth on the pivoting support, the parallel axes of described driftage driving gear is in the center line of pivoting support; Along the circumferencial direction of pivoting support several bolts are set at the inner edge of pivoting support, the axis of described bolt is parallel to the center line of pivoting support equally; Also be provided with rotation limit switch and position transducer in the outside of pivoting support, with the tooth engagement on interconnective gear of described rotation limit switch and the pivoting support.
Inboard at pivoting support is provided with break, and described break has 4～6, and each break all protrudes in the inwall of described pivoting support to gyration center.
Described rotation limit switch is installed on the case; This case has two parallel opposing sideplates, and be positioned at these two side end, be used for these two end plates that side plate links together; Described rotation limit switch bit is in the space that two side plates and end plate surround; Described gear is positioned in the rotating shaft of rotation limit switch.Side at case 7 is provided with sensor stand, and described position transducer is installed on sensor stand.
Advantage of the present invention is: 1, owing to adopted double ball pivoting support, the bearing capacity of Yawing mechanism strengthens.2, the driftage reducing motor adopts the soft start control strategy, has reduced because frequent clockwise and anticlockwise starts the fatigue damage that causes to Yaw gearbox.3, hydraulic brake design has the electric oil pressure of arrow from insurance system, guarantee blower fan vow under the electric situation, blower fan in week age, locked yaw system.4, the rotation limit switch is four contact mechanical limit switches, guarantee that yaw system moves in the operating range of safety, and be provided with the safe location point that unties the mooring rope, but the physical location of position transducer instant recording yaw system.
