Description
Technical field
The utility model is related to technical field of wind power generation, more particularly, is related to a kind of for wind power generating set
The brake disc of yaw system and brakes and wind power generating set comprising the brake disc.
Background technology
Yaw system is one of essential composition system of wind power generating set, and the main function of yaw system has two
It is individual：One is being cooperated with the control system of wind power generating set, make the wind wheel of wind power generating set all the time in shape windward
State, the generating efficiency of wind power generating set is improved to make full use of wind energy, i.e., to wind function；Secondly being to provide necessary braking
Torque, to ensure the safe operation of wind power generating set.To avoid wind power generating set from producing excessive shake in During yaw
Resonance that is dynamic and causing complete machine, therefore yaw system must have suitable damping torque in set yaw.Driven using gear
During dynamic yaw system, cause the driftage gear teeth to produce alternate load for the wind vector that avoids vibration, off-course brake should be used
(or yawdamper) vibrates to absorb small free deflection, to prevent the alternate stress of yaw gear from causing the gear teeth to damage too early
Wound.
Current wind generating set is designed with active yawing system, for driving cabin to rotate, and makes head aligning direction
To obtain maximum wind energy.Yaw system is mainly made up of brake and brake disc.When not going off course, the friction of brake
Piece clamps brake disc, keeps cabin angle constant；In During yaw, yaw system provides certain brake force, puts down driftage
Surely.Material, surface roughness, dust, abrasive dust, greasy dirt of the friction plate of brake disc and brake etc. have certain to yaw brake
Influence, when these conditions have variation, often results in the unstable of braking ability, and vibration noise when showing as yaw brake shows
As.
At present, mainly there is the following aspects the reason for vibration noise phenomenon for causing yaw brake to produce：1st, friction plate
When producing abrasive dust, abrasive dust accumulation is distributed on the rubbing surface of brake disc, and with yawing rotation, engaging friction is secondary interior, is formed and caused
Close hard adamantine layer, friction plate and brake disc rubbing surface can be scratched in yawing rotation, influence frictional behaviour, and produce driftage
Vibration and noise.2nd, friction area is not separated (friction area and non-model control by the structure of current brake disk with non-model control region
Region is a processing plane), cause when having the pollutant such as oil, fat, sewage water clock on the disc brake rotor, pollutant easily spreads
To friction area, engaging friction pair, because friction plate is very sensitive to pollutants such as oil, fat, sewage, causes frictional behaviour to drop therewith
Low or even deterioration, so as to produce yaw oscillation and noise.3rd, the rubbing surface of brake disc is typically processed by vertical milling vehicle, no
Do special disposal, it will usually in rubbing surface formation along the tangential annular processing texture of brake disc, because friction plate progress driftage is dynamic
As when be also to be moved along the circumferentially opposite of brake disc, so this tangential processing texture can cause the relative motion of friction pair
It is excessively smooth on direction, easily occur stribeck (this Trebek) friction effect, produce vibration and noise.
Therefore, the basic method for eliminating yaw brake vibration noise is exactly effective eliminates on the upper and lower surface of brake disc
The abrasive dust produced by drag friction, while reducing the contaminants such as water clock grease, sewage, abrasive dust on the disc brake rotor as far as possible
The area of rubbing surface, and flowing cleaning groove is designed, allow pollutant to flow out friction area automatically.
Utility model content

According to another aspect of the present utility model, the yaw oscillation caused by adamantine layer can effectively be eliminated by also providing one kind
The brake disc of noise and brakes and wind power generating set comprising the brake disc.
According to another aspect of the present utility model, a kind of stronger brake disc of wearability is also provided and comprising the braking
The brakes and wind power generating set of disk.
In order to realize the purpose, the utility model is adopted the following technical scheme that：A kind of driftage system for wind-driven generator
