Description
Technical field
The present invention relates to a kind of slip damping unit of wind power generation yaw system, specifically a kind of wind-force that is used for is sent out
The damper of electricity.
Background technology
During the work time, in order to make full use of wind energy to keep full hair-like state, wind turbine wind wheel must be with the wind for wind-driven generator
To the automatic corresponding rotation of change, remain that wind wheel is consistent with wind direction.To realize above-mentioned target, cabin must have a device with
Track wind vector, driving cabin rotate, and this device is exactly yaw system.Yaw system usually by wind direction detection controller, partially
Driving device, off-course brake and the yaw bearing etc. of navigating composition, wherein wind direction detection controller, deviation drive device and yaw system
Dynamic device is placed in cabin, and yaw bearing is respectively placed in cabin and tower, and yaw drive motor is by roller gear come driving machine
The gear ring in bilge portion, promotes the change of cabin box haul to deflect.The wind power generating set of original design is usually without considering to inclined
Boat is damped, and universal noise is excessive in During yaw, unit vibration is unstable.
The present invention sets damper, damper upper end connection cabin, lower side pressure between the cabin of wind-power electricity generation and sleeve
Tightly on the connection ring flat-plate of tower, since the friction plate of damper is with stable friction coefficient and special with certain self-lubricating
Property, the impact of preferably steady cabin is capable of in yaw startup, operation and stopped process, is reduced or eliminated since yaw causes
Cabin vibrations.
The content of the invention
The present invention is existing in the impact that yaw starts, steady cabin is subject in operation and stopped process, Yi Jiwei to solve
It is reduced or eliminated due to the cabin vibrations caused by yaw the problem of, it is desirable to provide a kind of wind-power generating yaw damper.
The technical solution adopted by the present invention includes cylinder, further includes the damping friction piece with self-lubricating property, the resistance
The one side of Buddhist nun's friction plate is fixed on the cylinder lower end, another face pressure of the damping friction piece using bonding or by the way of inlaying
Tightly on the connection ring flat-plate of tower.
Wherein, cylinder is cylindric.
Wherein, the spiral grooves around cylinder are carved with the outer wall of cylinder
Wherein, the lower end of cylinder is equipped with seal groove, and seal groove is built-in with sealing ring.
Compared to the prior art the present invention, has the friction plate of self-lubricating property, the stable friction factor of friction plate and resistance to
Abrasion.Can start in yaw, in operation and stopped process can preferably smooth drive motor Ground shock waves, be reduced or eliminated by
In cabin vibrations caused by yaw so that cabin yaw is more steady, effectively improves the efficiency and security of wind-driven generator；This
Invention has the characteristics that simple in structure, frictional damping is stable, of low cost, service life is long.
Brief description of the drawings
Fig. 1 is the structure diagram of one embodiment of the invention.
Fig. 2 is the structure diagram of one embodiment of the present of invention.
Referring to attached drawing, 1 is damping friction piece, and 2 be cylinder, and 3 be seal groove, and 4 be spiral grooves.
Embodiment
The present invention is further described in conjunction with attached drawing.
Referring to Fig. 1 and Fig. 2, Fig. 1, Fig. 2 show one embodiment of the present of invention, by the resistance with self-lubricating property
Buddhist nun's friction plate 1 and cylinder 2 are formed.Wherein, damping friction piece 1 is made of the raw material of following masses number：Graphite powder is
0.5%-23.5%, petroleum coke 0.1%-15%, ultra-fine tin bronze powder and/or brass powder 0.1%-5%, pitch 0.2%-25%, surplus are
Filling powder.In addition, further include vacuum impregnation resin 2%.Can conveniently, firmly using damping friction piece 1 made of mentioned component
Ground is combined with other materials, and bonding is firm；With self lubricity, equipment（Parts）Slide light；Friction coefficient is moderate, braking
Steadily, dust is few；With good wearability, service life length；Heat shock resistance, and high temperature restorability is good, can keep away at the same time
Exempt from the decline and expansion of high temperature, the ability with Time Continuous work.Because the preferred material as the present embodiment.It is specific and
Speech, the damping friction piece 1 of the present embodiment are made of the raw material of following masses number：
Crystalline flake graphite 5%, common graphite powder 15%；Petroleum coke 12.5%；Pitch 23%；Ultra-fine tin bronze powder 3%；
Filling powder carbon black 17.5%, flyash superfine fibre 13%, ceramic fibre 9%；Epoxy resin 2%.
In the present embodiment, damping friction piece 1 is fixed on 2 lower end of cylinder of metal, cylinder 2 using bonding or by the way of inlaying
Spiral grooves 4 are carved with outside, and the lower end of cylinder 2 is equipped with seal groove 3, built-in O-ring（Or other kinds of sealing ring）, use
When the present embodiment is fixed on to the lower part of wind power generator cabin, damping friction piece 1 is pressed on the connection ring flat-plate of tower.Work as cabin
During rotation, damping friction piece 1 smoothly slides on the connection ring flat-plate of tower.
Damping friction piece 1 not only has good intensity, wearability and agglomerability, but also has good self lubricity
Energy and heat-resisting quantity.Slide light during use, braking is steady, dust is few, and heat fading is small, high temperature restorability is good, service life
It is long.Can thus start in yaw, in operation and stopped process can preferably smooth drive motor Ground shock waves, be reduced or eliminated
The cabin vibrations caused by yaw so that cabin yaw is more steady, effectively improves the efficiency and security of wind-driven generator.
Further, the vacuum impregnation resin is one or more of in phenolic resin, epoxy resin, furane resins
Combination.
Further, filling powder includes the middle a kind of or several of carbon black, rubber powder, flyash superfine fibre and ceramic fibre
The combination of kind；The graphite powder includes one or more of combinations of crystalline flake graphite, fine graphite powder, common graphite powder；Institute
The ultra-fine tin bronze powder stated, brass powder can be replaced the one or more of light magnesium oxide, blanc fixe and precipitated calcium carbonate
Combination.
Above in conjunction with the accompanying drawings and embodiments embodiment that the invention has been described, the structure that embodiment provides is not formed pair
