Specific implementation mode
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in 2, a kind of wind-driven generator passive type yawing brake system, including cabin main structure 100, yaw are made
Dynamic device 320, yawing gear ring 200 etc..
Off-course brake 320 is connected by high-strength bolts in cabin main structure 100, and high intensity link bolt hole point
Cloth is linear type；Upper friction plate 327 is housed, upper friction plate 327 supports entirely between cabin main structure 100 and yawing gear ring 200
Cabin and wind wheel quality, and a part of friction braking torque is provided.The caliper body of off-course brake 320 and yawing gear ring 200 it
Between be respectively provided with radial friction piece 326 and lower friction plate assembly 325, radial friction piece 326 is coupled and is played with yawing gear ring 200
Radial elastic supporting role；Lower friction plate assembly 325 is made of lower friction plate, disk spring component 324 and pre-tightening mechanism 322,
Lower friction plate connects pre-tightening mechanism 322 below by disk spring component 324, and disc spring is adjusted by the nut of pre-tightening mechanism 322
Component 324 makes lower friction plate generate the pressing force to 200 lower surface of yawing gear ring, is produced together with 200 lower surface of yawing gear ring
Raw friction braking torque.
1) off-course brake is simple in structure, highly reliable
Its critical piece is as follows：Brake upper half matrix 321-1, brake lower half matrix 321-2, pre-tightening mechanism 322, dish-shaped bullet
Spring component 324, lower friction plate assembly 325 and radial friction piece 326；Component is used according to system function requirement and matching requirements
The exploitation of Top-Down thinkings is decomposed, and if dished spring assembly 324 selects DIN2092 standards high rigidity band conical surface disc spring, can be met big
Megawatt unit brakes pretightning force demand, and reduces by 20% contact stress than similar conventional disc spring, promotes fatigue life.
2) component versatility and interchangeability are strong, and interface and configuration needs are unified（See Fig. 3）
Essential core functor upper friction plate, lower friction plate assembly 325 and radial friction piece 326 are all made of standard square shape,
It avoids because type interface difference is using independent excessive characteristic Design, entirety uses simple and practical shape, passes through radial friction piece coupling
Arc radius control is closed to realize that the matching between different type of machines, main connector high-strength bolt distribution also have circular arc to be uniformly changed to
Straight line is uniformly distributed, is no longer limited by cabin main structure appearance and size；Yawing gear ring, cabin main structure and tower top method are also pushed simultaneously
Blue modular universalization design；
Off-course brake is designed as independent connection/brake unit, according to the difference demand of wind load and wind turbine nacelle quality, is led to
The quantity for crossing brake is matched, and standard interface and standard configurations reduce yaw, cabin, tower and pipeline harness
Interactive iteration between system and whole development design cycle, while decreasing handling of goods and materials and maintenance cost；
3) control of friction plate intelligence lubrication and wear monitoring；
By Self-lubrication Oil Injection from Mineral Product and master control strategy implement, friction consumptive material yaw friction plate is carried out certainly in set yaw operation
It is dynamic to lubricate at regular time and quantity, improve operating condition, lifting system stability (Db values, SSD amplitudes and heat after) and consumptive material use the longevity
Life；
Friction plate operating status is monitored in real time by digital simulation quantity sensor, can be can be obtained without personnel Deng Ta
One period of friction plate wears operating condition, greatly reduces O＆M intensity, while can predict friction plate service life again so that partially
Boat braking system O＆M period elastification；
4) preload and locking gear（See Fig. 4）
Pretightning force is most important to yaw frictional force, and pre-tightening mechanism 322 uses closely-pitched hexagonal big nut, is accurately controlled by screw pitch
Disc spring group decrement determines that pretightning force size, coarse pitch nut itself have the advantages that structural strength height and self-lock ability are strong, protects
Demonstrate,prove the stability of pretightning force/brake force；
Meanwhile coarse pitch nut can be screwed out from brake device lower half matrix 321-2, when checking and replacing dished spring assembly,
Brake-cabin main structure need not be removed with hydraulic spanner in advance and connect bolt, substantially reduce O＆M intensity；
Locking gear uses the chock 322-3 of interior 18 side scallop, with ± 21 ° of rotation regulated quantity, it can be ensured that
Hexagonal big nut all obtains stop locking in any turned position, further enhances the self-lock ability of entire mechanism.
It is characteristic of the invention that：
1) modular applications
According to complete machine demand, different wind power generating sets use this off-course brake, and being similar to lift heavy different weight counterweight needs
Different number lift heavy is wanted to connect bolt, for example, 2MW matches+50 load-bearing upper friction plates of 12 brakes, 3MW is with 15 brakings
+ 60 load-bearing upper friction plates of device, 5MW match+100 load-bearing upper friction plates of 24 brakes；
2) modular interface
Brake and the configuration interface of cabin main structure are same, after calculating required brake quantity, corresponding type cabin master
Structure can dissolve yaw interface according to off-course brake quantity demand, quick module, without carry out coupling radius of circle and its
The check and design of his size for connection push the complete machine degree of modularity, promote design and development efficiency；
3) reliability
It is controlled by intelligence lubrication, laboratory simulation operating condition is implemented into conversion and is implemented in the air, the use for the consumptive material that rubs
Reliability and stability are guaranteed, and problem and customer complaint quantity can be reduced greatly；
4) spare part versatility
Main components, connector and functor are same configuration, and borrow and matching can be easily achieved between different type of machines,
Break the limitation that material configures between different platform, is greatly ensured for safeguarding and rectifying and improving response promptness.
5) O＆M convenience
Pass through on-line real time monitoring, it can be deduced that the use state of major function part-friction consumptive material rationally judges and assessment is transported
The necessity of dimension reduces downtime and generated energy loss, increases customer satisfaction degree；
It avoids and needs to dismantle brake connection bolt because replacing dished spring assembly, can greatly reduce field maintenance person's O＆M
Intensity.
