Description
Technical field
The utility model relates to a kind of coupling, specifically a kind of diaphragm coupling for wind power generating set.
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.
The coupling of existing wind power generating set generally need possess following three zones:
1, transmitting torque: namely power is passed to generator from the output shaft of step-up gear.With brake disc on coupling, the break on overdrive gear tank shell can realize the braking to output shaft.
2, protective function: overload protection function and electric insulation functions.When generator be short-circuited, electrical network jump the fault such as electrical phenomena time, generator produces impulsive torque, if do not have available protecting, this impulsive torque can make step-up gear gear damage.Require that the electric insulation functions of coupling can effectively prevent high-altitude thunder and lightning from damaging generator simultaneously.
3, compensate function: inevitably there is the factor such as load metamorphism, thermal distortion under foozle, alignment error and dynamic condition in the fabrication process due to equipment, the shaft axis certainly existing axis, angle, radial direction etc. between generator and the axis of booster engine misaligns offset deviation.The diaphragm group arranged in the diaphragm coupling of wind power generating set, relies on the misalign offset deviation of its elasticity to equipment to make mediations, concessions, compromise and compensation, finally plays the effect of offset angle to, axial displacement.
The diaphragm coupling of conventional wind power generating set generally adopts four pore membrane sheet groups to compensate, although the diaphragm group compensation ability of this structure is maximum, its bearing capacity is poor, because wind power generating set volume is all very large, under emergency case, likely cause the damage of diaphragm group.In order to increase raising bearing capacity, the general method adopting increase diaphragm, such as, adopt octal diaphragm group, but increasing diaphragm inevitably reduces compensation ability.Gu there is certain paradox in the compensation ability of the diaphragm coupling of wind power generating set and bearing capacity.
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, how more to design a kind of diaphragm coupling of wind power generating set, can be in harmonious proportion its compensation ability and bearing capacity is those skilled in the art's problems urgently to be resolved hurrily.
