Description

A kind of wind-driven generator drive mechanism
Technical field
The present invention is about a kind of wind-driven generator, particularly relates to the dynamic branch formula wind-power electricity generation of a kind of easy care Machine drive mechanism.
Background technology
Driving-chain in wind-driven generator has the effect of transmission and speedup, is the core of blower fan.Wind-force is sent out The version of motor-driven chain is of a great variety, from the point of view of the kind of drive, can be divided into Planetary Gear Transmission, put down Row shaft gear transmission, hybrid transmission (i.e. planetary gear and parallel axes mixed drive).Hybrid biography is current Most popular structure type;In hybrid drive mechanism, general employing two-stage Gear Planet Transmission and one-level are fixed Axle carries out transmission and speedup, and whole drive mechanism is disposed in the cabin above tower.
Owing to blower fan is by the wind-force effect of irregular break-in and varying duty, and stand the impact of extreme difference in temperature throughout the year, In addition residing natural environment, the whole drive mechanism being arranged in cabin small space, once break down, Reparation is by extremely difficult;Therefore it is required that drive mechanism volume is little, lightweight, function admirable, reliable, therefore Barrier rate is low;The especially requirement to its reliability and service life is all much higher than common mechanical.
Blower fan reliability in the market is unsatisfactory, drive mechanism especially gearbox fault or damage draw The unit outage event risen happens occasionally, and thus brings the most serious direct losses and indirect loss, keeps in repair people Member puts into the workload of maintenance work and is also continuously increased.This is mainly due to the continuous increasing of Wind turbines single-machine capacity Greatly, the designing technique of drive mechanism relatively lags behind and causes.
Data show, what fan trouble rate was the highest is drive mechanism, is easiest to break down in drive mechanism It is gear-box, main shaft and base bearing.If drive mechanism breaks down, then maintenance cost is huge.By Structure in blower fan itself limits, and will fix a breakdown and need to disassemble impeller and whole cabin, fix a breakdown After, then reinstall go back to original position;Whole maintenance process is extremely complex, need special crane gear and Lifting device just can complete;Especially offshore wind turbine, dismounting expense once can reach up to ten million unit.
In order to reduce fault rate, reducing maintenance cost, most producers are attempted with more reasonably drive mechanism and arrange Mode improves the reliability of gear-box, main shaft and base bearing.The common form of blower fan drive mechanism presses main shaft Supporting way has: " two point form " support, " bikini " support and " one-point type " support etc..Wherein " two Point type " in supporting construction, main shaft is by two bearings, an axial restraint, another axial float, Torque is only reached gear-box by main shaft.In " one-point type " supporting construction, it is single bearings, transmission case body With main support integrated design.These several forms have respective feature, coordinate specific type, to a certain degree On make fault rate decrease.But the layout of these several forms does not fundamentally reduce maintenance cost.This It is because, on the one hand, the projected life of drive mechanism (based on gear-box) is 20 years, the actually used longevity Life can not reach design life, makes the maintenance of drive mechanism even change the most frequent.On the other hand, The dismounting of drive mechanism is the most complicated at present, needs to employ special equipment, spends huge manpower financial capacity.
