Background technique
Wind energy, as a kind of clean renewable energy sources, is more and more subject to the attention of countries in the world.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 109MW, and wherein available wind energy is 2 × 107MW, than the water energy total amount that the earth can develop also large 10 times.Wind Energy In China reserves are very large, it is wide to distribute, and only the wind energy content of land just has an appointment 2.53 hundred million kilowatts.
The Wind Power Generation Industry of China has also stepped into high speed development track.2014, national Wind Power Generation Industry continued to keep the strong growth impetus, annual wind-powered electricity generation adding new capacity 1,981 ten thousand kilowatts, adding new capacity records high, accumulative grid-connected electric motor power reaches 9,637 ten thousand kilowatts, accounts for 7% of whole capacity of installed generator, accounts for 27% of the installation of global wind-powered electricity generation.Wind-powered electricity generation electricity volume 1,534 hundred million kilowatt hour in 2014, accounts for 2.78% of whole generated energy.Wind power equipment manufacturing capacity also strengthen continuously, technical merit significantly promotes, and the newly-increased wind power equipment lifting in whole nation capacity 2,335 ten thousand kilowatts, increase by 45% on a year-on-year basis, national wind power equipment adds up lifting capacity and reaches 1.15 hundred million kilowatts, increases by 25.5% on a year-on-year basis.
Wind-driven generator is the dynamic power machine of mechanical work by wind energy transformation, and it utilizes wind-force to drive air vane to rotate, then promoted by the speed that booster engine will rotate, and impels electrical power generators.Wherein, need special high-speed flexible coupling to transmit motion wherein and power between the generator of Wind turbines and booster engine, thus, high-speed shaft of wind generating set Special flexible coupling is widely used in land, offshore high-altitude cabin (overhead or sea be about 75m place), is connected between booster engine output shaft and generator input shaft.
Conventional Special flexible coupling comprises cylindrical body and is connected to the flange plate of cylindrical body, each flange plate is socketed on the both sides of described cylindrical body respectively, adopts and be wound around the assembly that the flange plate of described cylindrical body and cylindrical body both sides is coupled to integral structure by bonding technology between described cylindrical body and described flange plate.But when transmitting torque, can produce larger impact force, cause very large impact to equipment, this type of Coupling Life is short, maintenance is frequent, can not meet larger transmission requirement.
Because Wind turbines uses in high-altitude, installation and maintenance are very inconvenient, and maintenance cost is expensive, once damaging appears in coupling, whole unit stall will be caused to generate electricity, and indirect loss is serious, thus very harsh to the reliability of coupling, security requirement, require in Two decades years lifetime non-maintaining.Therefore, the how more rational flexible coupling for the wind power generating set problem that to be those skilled in the art urgently to be resolved hurrily.
Model utility content
It is simple that main purpose of the present utility model is to provide the purpose of this utility model to be to provide a kind of structure, safe and reliable and can reduce the flexible coupling for wind power generating set that shakes.
For reaching above object, the technical solution adopted in the utility model is: a kind of flexible coupling for wind power generating set, comprise flexible intervalve, be bonded in the bonding flange at described flexible intervalve two ends, be separately positioned on gear-box axle sleeve and the generator axle sleeve at coupling two ends, connect the compensating diaphragm assembly of described gear-box axle sleeve and described generator axle sleeve respectively, and connect the overload protection assembly of compensating diaphragm assembly described in side; It is characterized in that: bond described in side between flange and described overload protection assembly and be connected with connecting flange; described connecting flange offers mounting hole towards described bonding flange side; elasticity bolt is connected with in described mounting hole; tapped hole is provided with in described elasticity bolt; attachment bolt is provided with in described tapped hole; described bonding flange and described connecting flange, through described bonding flange, are linked together by described attachment bolt.Elasticity bolt the impact force that can effectively reduce to produce when transmitting torque is set, play a shock absorbing effect, and this structure is simple, safe and reliable.
As improvement, described elasticity bolt outer side wall is provided with restraining groove, in described mounting hole, is provided with the positive stop key coordinated with described restraining groove.Prevent from, when attachment bolt precession tapped hole, relatively rotating between elasticity bolt and connecting flange.
As preferably, described restraining groove is three, and is evenly distributed on described elasticity bolt, and corresponding described positive stop key is three, and is evenly distributed in described mounting hole.Triple bond is spacing is the not only convenient but also reliable limit method of one.
As preferably, described mounting hole is two to ten two, and corresponding described elasticity bolt is two to ten two.Mounting hole needs to control in a rational quantitative range.
As preferred further, described mounting hole is four, and corresponding described elasticity bolt is four.This is that a more rational quantity is selected.
As preferably, described elasticity bolt is rubber bolt.Rubber is a kind of conventional elastic material, has the effect reducing vibrations.
Compared with prior art, the utility model has the advantage of: by the elasticity bolt arranged, effectively reduce the impact force produced when transmitting torque, play a shock absorbing effect, and this structure is simple, safe and reliable.
