Background technology
It is frequently seen longer one section of Wind turbines tower top and is all attached to one layer of greasy dirt, pollutes environment, influence attractive in appearance.Through
Analyzing main cause is：1. Wind turbines during operation, it is necessary to periodically inject new lubricating grease into yaw raceway, it is old
Or unnecessary lubricating grease can seal spilling from yaw, if the driftage gear wheel on yaw is external tooth, these profits
Consistent lubricant runs past driftage gear wheel and infects tower drum outer wall.2. old or unnecessary driftage gear wheel（External tooth）Lubricating grease is same
Tower drum outer wall can be infected.In addition, under yaw after sealing wear, the lubricating grease in yaw raceway is understood seepage and dropped
Onto yaw brake disc, these lubricating grease spread to upper and lower brake area region, the normal brake application function of yawing brake system
It will lose, so as to influence the normal operation of Wind turbines.Generally for tower drum outer wall greasy dirt using the method for periodic cleaning come
Solve, shortcoming is work high above the ground, is wasted time and energy, dangerous big, and can inevitably cause the secondary dirt to on-site soil
Dye；The pollution being subject to for brake area, if it find that not in time, the shutdown maintenance of the unplanned property of Wind turbines can be caused,
Increase maintenance cost, reduce wind power plant generated energy.A kind of therefore, it is proposed that Wind turbines yaw brake disc.
Utility model content
The purpose of this utility model is in order to solve shortcoming present in prior art, so as to a kind of Wind turbines proposed
Yaw brake disc.
To achieve these goals, the utility model employs following technical scheme：
A kind of Wind turbines yaw brake disc, including mainframe are designed, the lower end of the mainframe is connected by the first bolt
Yaw inner ring is connected to, the side of the yaw inner ring is crossed provided with yaw, and the yaw crosses another
Side is connected with yaw outer ring, and the opposite face of the yaw inner ring and yaw outer ring is respectively equipped with yaw
Upper seal and yaw lower seal, the yaw upper seal is located at the top that yaw crosses, described inclined
Boat bearing lower seal is located at the lower section that yaw crosses, and the yaw outer ring is set away from the side that yaw crosses
There is driftage gear wheel, the bottom of the mainframe is provided with braking yaw disk, and the braking yaw disk top and bottom decibel is provided with
Annular gear is oily raised and annular gear oil groove, the raised and annular gear oil groove of annular gear oil are located under yaw lower seal
Inclined side is held, the outer ledge of the braking yaw disk is provided with annular oil storage tank, and the annular oil storage tank is positioned at driftage gear wheel
Underface, the lower end side of the braking yaw disk are provided with tower, and the tower is connected by the second bolt and yaw outer ring
Connect.
Preferably, the lower end of the braking yaw disk and lower end are brake area, and the width of brake area is equal
It is identical.
Preferably, seamless applying connection between the yaw inner ring and yaw outer ring.
The utility model proposes a kind of Wind turbines yaw brake disc, beneficial effect is：Existed by yaw brake disc
On the basis of original brake disc function, some special simple structures are added, for preventing yaw inner ring, yaw
Yaw brake disc rubbing surface on outer ring and driftage gear wheel grease contaminated tower drum outer wall and braking yaw disk, yaw brake disc
The structure of annular oil storage tank is provided with, yaw brake is provided with the oily raised and annular gear oil groove of annular gear and can stored from when lubricating
The old or unnecessary lubricating grease of caused spilling, structure of the present utility model can greatly reduce the work of Wind turbines maintenance
Amount, reduces the danger of maintenance work, mitigates the pollution to environment, while can also reduce the unplanned property shutdown maintenance of Wind turbines
Possibility.
