Description
Technical field
The present invention relates to wind-driven generator, the connection knot between the mainframe and tower of specifically a kind of wind-driven generator
Structure.
Background technology
In the molding structure of wind-driven generator, tower and mainframe are the load bearing component of most critical respectively.Wherein, tower
Effect be in tens of rice or even rice up to a hundred by mainframe etc. by parts carries such as the wind wheel of wind-driven generator, electricity generation systems
High-altitude carry out wind energy conversion；The effect of mainframe is that the components such as wind wheel, the electricity generation system of wind-driven generator hold
It carries.In order to which wind wheel is made to can adapt to the wind vector of the Nature, to carry out to pneumatic work, mainframe is by the inclined of yaw system
Boat bearing is installed on atop a tower, i.e. mainframe can be corresponded to by the yaw bearing of yaw system at the top of tower
Circumferentially displaced action to capture wind direction.
The yaw system of wind-driven generator is mainly by yaw bearing, yaw drive, off-course brake and lubricating system
Wait the complete set of equipments of compositions.In existing wind-driven generator structure, yaw bearing is disposed axially in tower by two groups of clamping screws
Between cylinder and mainframe（One group of clamping screw is corresponding for locking mainframe and yaw bearing inner ring/outer ring, another
Group clamping screw is used to lock tower and yaw bearing outer ring/inner ring）, and yaw drive, off-course brake and lubricating system
It is arranged on mainframe etc. integrated, and yaw drive, off-course brake and lubricating system etc. are corresponding with the structure of yaw bearing
Connection.
Since the load that the yaw bearing of wind driven generator yaw system is born with it has the correspondence of matching,
Once larger significant change occurs for the component weight carried on mainframe, the spy of different regions wind energy resources is for example, adapted to
Property and make the factors such as the variation of length of blade, necessarily involve yaw system yaw bearing design change.However, above-mentioned existing
Have in the connection structure between the mainframe of wind-driven generator and tower, the change in design of yaw bearing is necessarily involved to host
The change of frame structure, otherwise original host frame is can not to be matched with the designed yaw bearing changed, this will cause wind-force to be sent out
The global design of motor, manufacture cost are significantly increased, it can be seen that, the company between the mainframe and tower of existing wind-driven generator
Binding structure limits versatility of the mainframe between different type of machines, less economical.
In addition, the connection structure between the mainframe and tower of above-mentioned existing wind-driven generator so that entire mainframe
Integrated morphology volume can substantially increase, this is especially with the most apparent of high-power wind-driven generator, so as to influence mainframe
Transport flexibility, transportation technology difficulty and of high cost.
Invention content
The technical purpose of the present invention is：In view of the above shortcomings of the prior art, wind-power electricity generation can either be made by providing one kind

Technical solution is used by the present invention realizes its technical purpose：A kind of wind-driven generator mainframe is connect with tower
Structure including mainframe and tower, is separately provided with a yaw transition bracket between the mainframe and tower, described to yaw
It crosses and yaw bearing, off-course brake and yaw drive is at least configured on stent, the yaw transition bracket is axially connected to
Yaw bearing between mainframe and tower and on the yaw transition bracket makes mainframe pass through partially as a connecting pin
Boat transition bracket is axially connected to the top of tower.
Preferably, the lower end of the yaw transition bracket is axially connect with yaw bearing, the off-course brake
Yaw brake disc be fixed on the lower end surface of yaw bearing, it is described yaw yaw bearing and tower of the transition bracket by lower end
The top of cylinder axially connects.
Further, the yaw transition bracket is driving external structure, the lower end of the yaw transition bracket and yaw
The inner ring of bearing axially connects, and the outer ring of the yaw bearing and the top of tower axially connect, the outer ring of the yaw bearing
Periphery wall is equipped with sliding tooth, on the yaw transition bracket yaw drive that is configured be on the outside of yaw transition bracket and with
Driving tooth engagement on the outer ring periphery wall of yaw bearing.Further, the lower end of the yaw transition bracket is with flange knot
Structure is axially connect by several connection bolts two being circumferentially arranged with the inner ring of yaw bearing.The outer ring of the yaw bearing leads to
Several connection bolts one being circumferentially arranged are crossed axially to connect with the flange arrangement of atop a tower.
Alternatively, further, the yaw transition bracket is driving embedding structure, the lower end of the yaw transition bracket with
The outer ring of yaw bearing axially connects, and the inner ring of the yaw bearing and the top of tower axially connect, the yaw bearing
Inner ring internal perisporium is equipped with sliding tooth, on the yaw transition bracket yaw drive that is configured be on the inside of yaw transition bracket,
And with the driving tooth engagement on the inner ring internal perisporium of yaw bearing.Further, the lower end of the yaw transition bracket is with method
Blue structure is axially connect by several connection bolts two being circumferentially arranged with the outer ring of yaw bearing.The yaw bearing it is interior
Circle is axially connect by several connection bolts one being circumferentially arranged with the flange arrangement of atop a tower.
Preferably, the upper end of the yaw transition bracket is connected with flange arrangement by several be circumferentially arranged
Bolt three is axially connect with the flange arrangement of mainframe lower end.
The method have the benefit that：One is separately provided between mainframe and tower and yawed for above-mentioned connection structure
Stent is crossed, include yaw bearing, off-course brake and the yaw that arrangement yaw system is specially integrated by the yaw transition bracket are driven
Component including dynamic device etc., i.e., form a modular yaw transition bracket, the yaw transition between mainframe and tower
On the mainframe and tower that stent not only modular can be applied to each specifications and models and match, but also when it come to arrive yaw
The change in design of bearing then only makes corresponding change in design to yaw transition bracket（Preferably at most to entirely yawing transition
Stent and the yaw system integrated make corresponding change in design）, without to mainframe, row carries out the design of high cost more again
Change, so that the mainframe of wind-driven generator has good versatility between multiple and different types, meanwhile, yaw transition
The split absolute construction of stent and mainframe is conducive to enhance flexibility and the reliability of mainframe transport and installation operation, whole
Body remarkable in economical benefits, it is reliable and practical.
