Embodiment
Below in conjunction with embodiment, the present invention is elaborated.
The term such as front, rear, left and right in the present embodiment, is only relative concept each other or is reference with the normal operating condition of product, and should not be regarded as have restrictive.
As shown in Figure 1, super-huge wind power generating set of the present invention comprises wind wheel apparatus 1, main shaft 2, main bearing device 3, mainframe 4, speed increaser 5, speed increaser yielding support 6, high speed shaft coupling 7, generator 8, rear bay 10.Wind wheel apparatus 1 is connected with main shaft 2 front end by bolt, and main shaft 2 is through main bearing device 3, and main bearing device 3 is arranged on mainframe 4 front end, and main shaft 2 rear end and speed increaser 5 input shaft 5.5 are bolted.Wind wheel apparatus 1 is in order to capturing wind energy.Main shaft 2 can be casting or forging structure.Main bearing device 3 plays supports main shaft 2 and acts on.Speed increaser yielding support 6 supports speed increaser 5, and speed increaser yielding support 6 has certain rigidity and damping characteristic, for absorbing the impulsive load of speed increaser 5.The input shaft of the output shaft of speed increaser 5 with generator 8 is connected by high speed shaft coupling 7.Main bearing device 3 and speed increaser yielding support 6 are arranged on mainframe 4.Generator 8 is arranged on rear bay 9, and rear bay 9 is connected with mainframe 4.Forebay 4 is cast structure, and rear bay 10 is welded structure, and forebay 4 and rear bay 10 are bolted.
For 2 identical generators, inventive concept of the present invention is described in the present embodiment.As shown in Figure 2, speed increaser 5 comprises two output shafts 5.1,5.2, left toggle 5.3, right toggle 5.4, input shaft 5.5 and transmission system.Speed increaser yielding support 6 is identical two pieces, for not being 6.1,6.2.High speed shaft coupling 7 is identical two pieces, is respectively 7.1,7.2.Generator 8 is the two pieces that rotation direction is contrary, is respectively 8.1,8.2.As shown in Figure 3, transmission system is that the parallel one-level that adds of two-stage planet one-level crosses wheel construction, comprises input stage planet carrier 9.1, input stage gear ring 9.2, input stage planet wheel 9.3, input stage sun gear 9.4, secondary planet frame 9.6, secondary gear ring 9.5, secondary planet wheel 9.7, secondary solar gear 9.8, parallel stage driving wheel 9.9, parallel stage follower 9.10, initiatively third wheel 9.11, driven third wheel 9.12.Speed increaser input shaft 5.5 is connected with input stage planet carrier 9.1, and output shaft of the speed increaser 5.1,5.2 is connected with parallel stage follower 9.10, driven third wheel 9.12 respectively.Speed increaser yielding support 6.1,6.2 is fixed on mainframe 6, and supports the left and right toggle 5.3,5.4 of speed increaser 5 respectively, and coupling 7.1,7.2 is respectively in order to connect the input shaft of the generator 8.1,8.2 of the output shaft 5.1,5.2 and two of speed increaser 5.
During work, the wind energy transformation of catching is the kinetic energy that wind wheel apparatus 1 rotates by wind wheel apparatus 1, and be delivered to speed increaser input shaft 5.5 by main shaft 2, thus drive input stage planet carrier 9.1 to rotate, engaged each other by input stage gear ring 9.2, input stage planet wheel 9.3, input stage sun gear 9.4, and then drive secondary planet frame 9.6 to rotate; Engaged each other by secondary gear ring 9.5, secondary planet wheel 9.7, secondary solar gear 9.8 again, drive parallel stage driving wheel 9.9 to rotate; Parallel stage driving wheel 9.9 engages with parallel stage follower 9.10, initiatively third wheel 9.11 respectively, and initiatively third wheel 9.11 and driven third wheel 9.12 engage, and finally make output shaft 5.1,5.2 rotate.Because active third wheel 9.11 does not change transmission speed, only change transmission direction.Therefore the synchronized counterrotating of output shaft 5.1,5.2 can be made.After rotating speed finally can be made to raise, again energy is delivered to two coupling 7.1,7.2 fifty-fifty by two output shafts 5.1,5.2, and then is delivered to two generators 8.1,8.2.The kinetic transformation that generator rotates is the most at last electric energy, realizes wind-power electricity generation.Clutch can also be respectively arranged with between two coupling, 7.1,7.2 and two generators 8.1,8.2.When an alternator failure, such as, when generator 8.1 breaks down, be that coupling 7.1 is separated with generator 8.1 by solenoidoperated cluthes, form protection to generator 8.1, generator 8.2 continues generator operation.Now appearance 1/2nd falls in unit.When generator 8.2 breaks down, principle is as the same.
The present invention's two little generators replace single high-rating generator, and such as, for 12MW wind power generating set, can adopt the generator of two 6MW, this greatly reduces manufacture difficulty.In the present invention, the rotation direction of two output shafts of two generators is contrary, solves the knotty problem of loading imbalance; And so also reduce the manufacture cost of complete machine.Therefore technology of the present invention can be widely used in the super-huge Wind turbines of the 10MW ranks such as 3MW, 6MW, 9MW, 12MW.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
