Description
Technical field
This utility model relates to wind-driven generator, is especially the cabin yaw system of a kind of wind-driven generator.
Background technology
The yaw system of wind energy conversion system, also referred to as to wind apparatus, its role is to when the direction of wind vector changes, it is possible to
Quick smoothly it is directed at wind direction, in order to wind wheel obtains maximum wind energy, if without driftage damping structure during driftage, it will produce acutely
Vibration, damages yaw motor and yaw, increases extra excitation load simultaneously, and amplitude impact is surveyed wind data, reduced unit
Generating efficiency, reduces unit fatigue life.
Existing yaw system include cabin fix with tower the yaw inner ring that is connected fixing with cabin be connected and
The bearing outer ring of synchronous rotary and the braking auxiliary member being positioned at above yaw inner ring and being nested in cabin, brake auxiliary member
And it is provided with friction plate between yaw inner ring, owing to existing braking auxiliary member friction plate is split-type structural, needs during connection
Want an additionally mounted connection inserting part, different because of the degree of wear due to Friction Disk Surface so that friction plate and yaw inner ring
There is uneven or relative movement in plane, when liquid braking device action, and friction plate and yaw inner ring meeting, connection inserting part and system
All can produce huge strike note between actuation assistance, noise is relatively big, affects the orthobiosis of periphery crowd.
Utility model content
Technical problem to be solved in the utility model: the cabin driftage system of the wind-driven generator that a kind of noise is little is provided
System.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: a kind of wind-power electricity generation
The cabin yaw system of machine, it includes that cabin is fixed the yaw inner ring being connected and fixed the bearing being connected with cabin with tower
Outer ring, it is characterised in that: it is positioned at the also nested braking in the top auxiliary cylinder of yaw inner ring on described cabin, brakes auxiliary circle
Being provided with friction plate between post and yaw inner ring, friction plate is connected with braking auxiliary cylinder integral type；When friction plate and driftage
During bearing inner race air spots, braking auxiliary cylinder is relative to yaw inner ring rotation.
As preferably, described braking auxiliary cylinder sinters with friction plate.
As preferably, the surface that described cabin is positioned at braking auxiliary cylinder is provided with for by braking auxiliary cylinder
The liquid braking device that friction plate offsets with yaw inner ring.
Use said structure, this utility model advantageously: by friction plate with braking auxiliary cylinder integral type even
Connect, reduce the strike note between itself friction plate and braking auxiliary cylinder, it addition, liquid braking device is to braking auxiliary cylinder
Applying pressure, braking auxiliary cylinder transfers the pressure to yaw inner ring, and friction plate creates bigger damping action, when rubbing
The degree of wear of pad own is different and causes Friction Disk Surface with yaw inner peripheral surface the most at ordinary times, due to braking auxiliary cylinder
It is to be nested in cabin, and braking auxiliary cylinder is cylindrical structural so that braking auxiliary cylinder can occur rotation, to friction
The surface of sheet carries out polishing action until friction plate offsets completely with yaw inner peripheral surface portion, thus ensures steadily driftage,
Reduce the shock between friction plate and braking auxiliary cylinder, the noise that reduction equipment brings.
Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of the cabin yaw system of a kind of wind-driven generator of this utility model.
As shown in the figure: 1-cabin, 2-yaw inner ring, 3-bearing outer ring, 4-braking auxiliary cylinder, 5-friction plate, 6-
Liquid braking device.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
In this utility model describes, it is to be understood that term " on ", D score, " interior ", indicating position or the position such as " outward "
The relation of putting is based on the position relationship described in accompanying drawing, is for only for ease of the description present invention or simplification describes rather than instruction must
The specific orientation that must have.
As it is shown in figure 1, the cabin yaw system of a kind of wind-driven generator, it includes that be connected inclined is fixed in cabin 1 with tower
Boat bearing inner race 2 bearing outer ring 3 that be connected fixing with cabin 1, the top that described cabin 1 is positioned at yaw inner ring 2 is the most embedding
Set braking auxiliary cylinder 4, is provided with friction plate 5, friction plate 5 and braking auxiliary between braking auxiliary cylinder 4 and yaw inner ring 2
Cylinder 4 integral type connects；When friction plate 5 and yaw inner ring 2 air spots, braking auxiliary cylinder 4 is relative to yaw axis
Hold inner ring 2 rotation.
Described braking auxiliary cylinder 4 sinters with friction plate 5.
The surface being positioned at braking auxiliary cylinder 4 on described cabin 1 is provided with for by the friction plate on braking auxiliary cylinder 4
5 liquid braking devices 6 offseted with yaw inner ring 2.
Friction plate 5 is connected with braking auxiliary cylinder 4 integral type, reduces itself friction plate 5 and braking auxiliary cylinder 4
Between strike note, it addition, liquid braking device 6 applies pressure to braking auxiliary cylinder 4, braking auxiliary cylinder 4 is by pressure transmission
To yaw inner ring 2, friction plate 5 create bigger damping action, when the degree of wear of friction plate 5 own different and cause rubbing
When pad 5 surface and yaw inner ring 2 air spots, owing to braking auxiliary cylinder 4 is to be nested in cabin 1, and brake auxiliary
Help cylinder 4 for cylindrical structural so that braking auxiliary cylinder 4 can occur rotation, the surface of friction plate 5 is polished action straight
Offset completely with yaw inner ring 2 surface element to friction plate 5, thus ensure steadily driftage, reduce friction plate 5 and braking auxiliary
Shock between cylinder 4, the noise that reduction equipment brings.
This utility model is also equipped with other structures, owing to not designing inventive point, does not launch explanation at this.
Being described this utility model and embodiment thereof above, this description does not has restricted, shown in accompanying drawing
Be also one of embodiment of the present utility model, actual structure is not limited thereto.If generally speaking this area
Those of ordinary skill is enlightened by it, is creating in the case of objective without departing from this utility model, without creative design with
Frame mode that this technical scheme is similar and embodiment, all should belong to protection domain of the present utility model.
