Abstract
The invention relates to a wind power yaw brake testing stand. The wind power yaw brake testing stand mainly comprises a foundation (1), a bearing roller (2), a tooth ring (3), a brake disc (4), a center shaft (5), a rotation disc (6), a driving gear (7), a speed reducer (8), a force cell sensor (9) and a tested brake (10). According to the testing stand, the brake disc of which the dimension is same as the dimension of a wind turbine generator yaw brake and a similar mounting mode are employed; the brake disc can rotate 360 DEG, so a movement mode is completely different from a reciprocating motion mode of a testing device in the prior art, and great simulation effects are realized; not only can the brake characteristic of the yaw brake be tested, but also vibration and noise of a brake friction process can be truly tested; when the testing stand is mounted on a wind turbine generator tower, the simulation effect is better. The testing stand is advantaged in that the structure is simple, the brake and the brake disc can be conveniently replaced, and brake force can be stably and accurately measured.
Description
Technical field:
Patent of the present invention relates to a kind of Yawing brake of aerogenerator testing stand, belongs to wind-powered electricity generation field tests.
Background technology:
Off-course brake is the critical component that wind power generating set controls impeller direction.Off-course brake clamping brake disc, by
Frictional force makes impeller fixing in a desired direction.
In order to ensure the reliability of off-course brake, it is necessary to its performance of sampling Detection and wear-out life.Existing method of testing is
Substituting brake disc with a reciprocating iron plate, move back and forth with hydraulic jack push-and-pull iron plate, off-course brake clamping iron plate is produced
Raw brake force, the size of brake force is measured by the force transducer between oil cylinder and iron plate.
Although existing method of testing is simple, but test result is very poor with the concordance of actual application.The most important thing is test
System simulation is bad, it is impossible to measure the brake oil that the vibration of real system produces.
Summary of the invention:
The invention provides a kind of brake disc can 360 ° of rotations, be totally different from the reciprocating manner of existing test device
Wind turbines off-course brake testing stand.
In conjunction with accompanying drawing, it is described as follows:
A kind of wind power yawing brake tester, mainly by base 1, backing roll 2, gear ring 3, brake disc 4, central shaft 5,
Rotating disk 6, driving gear 7, reductor 8, force cell 9 and tested brake 10 form；
It is fixed with central shaft 5 on described base 1 and with central shaft 5 axle center as the center of circle, prolongs consolidating of circumference six decile layout
Dead axle 11；Being set with backing roll 2 on fixing axle 11, backing roll 2 holds up gear ring 3 and guides, and makes gear ring 3 level to turn
Dynamic；Bearing set 12 and rotating disk 6 on central shaft 5, described rotating disk 6 is triangle, centered by central shaft 5 axle center,
Respectively equipped with driving gear 7 to engage with gear ring 3 on three angles, an angle of rotating disk 6 is extended, end and force cell 9
Coupling, the other end of force cell 9 couples with support 13, and support 13 is fixed on base 1；Drive when driving gear 7
When dynamic gear ring 3 rotates, driving force can be measured by force cell 9.
Described gear ring 3 inner edge flange is used for installing brake disc 4, and tested brake 10 is then fixed on base 1, by liquid
The tested brake of pressure device 10 can be to brake disc 4 clamping braking, and the counteracting force of brake force is then passed by the dynamometry on rotating disk 6
Sensor 9 is measured.
Described driving gear 7 is respectively driven by a reductor 8 and motor 14；Motor 14 by converter change rotating speed and
Rotation direction.
Beneficial effect: the present invention uses the brake disc with Wind turbines off-course brake 1:1 size and akin installation
Mode.Brake disc can 360 ° of rotations, be totally different from the reciprocating manner of existing test device.Gu and have well
Simulation.Except the braking characteristic that can test off-course brake, it is also possible to authentic testing goes out the vibration during drag friction and makes an uproar
Sound.When being arranged on Wind turbines king-post, simulation effect is more preferable.
This testing stand has simple in construction, brake and brake disc and changes conveniently, and the advantages such as accurate are stablized in brake force measurement.

Detailed description of the invention:
Below by specific embodiment, the present invention is described in more detail:
As depicted in figs. 1 and 2, base 1 is fixed with central shaft 5 and with central shaft 5 center for center of circle circumference six decile
The fixing axle 11 arranged.Bearing set 12 and rotating disk 6 on central shaft 5.Fixing axle 11 is set with backing roll 2.?
Runner 2 holds up gear ring 3 and guides, and makes gear ring 3 to horizontally rotate.Rotating disk 6 is triangle, with central shaft 5 axle center is
The center of circle, respectively equipped with driving gear 7 to engage with gear ring 3 on three angles.Each driving gear 7 is by planetary reducer 8 He
Motor 14 drives.Motor 14 is turned to by frequency converter timing and change.One angle of rotating disk 6 is extended, end and dynamometry
Sensor 9 couples, and the other end of force cell 9 couples with support 13, and support 13 is fixed on base 1.
The inner edge flange of gear ring 3 is used for installing brake disc 4, and tested brake 10 is then fixed on base 1.Brake 10
Clamping brake disc 4 can produce brake force to the brake disc 4 rotated.The numerical value of brake force is by force cell 9 and department of computer science
Unified test goes out.
This testing stand uses 1:1 brake disc, and simulation is good.Remove the braking characteristic that can measure off-course brake, also can fully survey
