Embodiment
Below in conjunction with accompanying drawing concrete structure of the present invention is further described.
Wedge block inserted type off course brake provided by the invention is to utilize yaw gear and wedge-shaped blocks to form the plug-in type braking device.For example external yaw gear adopts the outside wedge-shaped blocks of installing to insert between wheel tooth and fixes cabin and pylon.Internally yaw gear adopts the inner wedge-shaped blocks of installing to insert between wheel tooth and fixes cabin and pylon.Fig. 2 is the structural representation of the driftage Slewing Support Mechanism of band out yawing gear.It comprises out yawing gear 1, driftage pivoting support outer bearing ring 2 and driftage pivoting support inner bearing ring 3.
Fig. 3 is when adopting band out yawing gear Slewing Support Mechanism, a kind of embodiment's of Wedge block inserted type braking device structural representation.Wedge-shaped blocks drive unit 5 is fixed on the engine room foundation 4 of rotation.Figure is that wedge-shaped blocks 6 radially inserts.
Fig. 4 is when adopting band out yawing gear Slewing Support Mechanism, the another kind of embodiment's of Wedge block inserted type braking device structural representation.The drive unit 5 of wedge-shaped blocks is fixed on the engine room foundation 4 of rotation.Figure is the axial insertion of wedge-shaped blocks 6.
For the yaw system Slewing Support Mechanism of yaw gear in adopting, similar when the Wedge block inserted type braking device is with out yawing gear Slewing Support Mechanism with employing.
The number of teeth of domestic widely used certain 1.5MW wind energy conversion system out yawing gear is 164 at present, this means that the driftage control accuracy is 2.2 ° of 360/164 ≈.If think that this precision is on the low side, can adopt device as shown in Figure 5:
Fig. 5 is that this device comprises one during with the fixing fluted disc 7 of described yaw gear and pylon, the embodiment's of Wedge block inserted type braking device structural representation.Several wedge-shaped blockss that match with this fluted disc 76 and the drive unit 5 that is used to drive this wedge-shaped blocks are installed on engine room foundation 4.Shown in the figure is the radially insertion of wedge-shaped blocks.The number of teeth of fluted disc can be determined according to the driftage required precision.
The drive unit of wedge-shaped blocks can adopt hydraulic pressure or electromagnetic coil drive unit, and hydraulic pressure or electromagnetic coil power up driving, and spring returns, and also can adopt the design of " failure safe ", and spring is pressed into, and hydraulic pressure or electromagnetic coil power up and return.
Wedge-shaped blocks described in the present invention is that single tapering wedge-shaped blocks, double tapered wedge-shaped blocks or top are the wedge-shaped blocks of cylndrical surface.
In detailed calculated behind the required moment of torsion of driftage braking, because the size of wedge-shaped blocks is determined that by the between cog size of gear remaining is exactly the number of definite wedge-shaped blocks.Wedge-shaped blocks generally can be set on circumference uniform.As contradictory on the fruit structure, can be not uniform yet.
Driftage precision and operational instruction
When adopting the Wedge block inserted type braking device, according to existing certain 1.5MW wind energy conversion system out yawing gear, it has 164 teeth, this means that the driftage control accuracy is 2.2 ° of 360/164 ≈, general error can satisfy the driftage requirement in principle between 0～1.1 °.If adopt the described structure of Fig. 5, the precision of then going off course can greatly improve.
Can aim between cog more accurately in order to make driftage braking wedge-shaped blocks, so that insert, can consider to adopt control system accurately to control the method for driftage angle, simultaneously at each mounting point, break relevant position sensor, when finishing, driftage judges whether wedge-shaped blocks inserts, to guarantee the safe and reliable of unit operation.
