In wind-driven generator, step-up gear is the critical component of wind-driven generator; Rapidly, domestic 1.5 megawatts and 2 megawatt wind driven generators have produced and have been applied to wind energy turbine set generating in batches to China's megawatt-grade high-power accelerating gearbox for wind power generator development with step-up gear at present, and 3 megawatt blower fan step-up gears are small lot application also.Because powerful wind-driven generator need to obtain larger wind-force, but larger wind-force also means that gear-box applying working condition is more severe, load condition is more complicated, maintenance and maintenance difficulty larger.In order to meet severe complicated operating mode and to reduce maintenance cost, when design, reliability, the maintaining easily property etc. of gear-box is that those skilled in the art must top-priority problem.
Model utility content
The purpose of this utility model is: provide a kind of new accelerating gearbox for wind power generator for bearing capacity problem, the gear-box of the torsion pass problem between the each parts that use the step-up gear of relatively high power more than 2 megawatts to solve, spring bearing is lubricated with the problem such as sealing problem and high aerial property easy to maintenance.
The purpose of this utility model is achieved in that a kind of Speedup gear box for high-power wind generator, the two-stage parallel pinion shaft system and the lubrication system that comprise casing, line of input star wheel series, are formed by first order train of gearings and output gear train, it is characterized in that: casing comprises the ring gear in toggle, line of input star wheel series and contains upper box and the rear box of lower box, between them, is connected as a single entity by bolt and cylinder location; Input sun wheel shaft in line of input star wheel series passes to female splined shaft by spline by moment of torsion, female splined shaft by bearings on casing, first order gearwheel is installed on female splined shaft by flat key, and output gearwheel is installed on first order gear shaft by flat key; The planet carrier of line of input star wheel series and the connecting part of toggle, the output gear shaft of output gear train and the connecting part of rear box all adopt disc and transparent cover.
In the utility model: the oil leab in lubrication system arrives at injection loop by rear box, between injection loop and input planet carrier, be provided with the ring slider of tin bronze alloys casting.
The utility model has the advantage of: because casing comprises the ring gear in toggle, line of input star wheel series and contains upper box and the rear box of lower box, between them, be connected as a single entity by bolt and cylinder location, structure is compacter, safeguards conveniently, also can ensure positioning precision; Because the moment of torsion transmission between planetary gear train and first order train of gearings is by spline, and moment of torsion transmission between first order train and output wheel train is by flat key, and the mode of this transmitting torque is simple and reliable, and dismounting, processing and install also all more convenient; Because the connecting part of connecting part, output gear shaft and the rear box of inputting planet carrier and front casing all adopts disc and transparent cover, ensure the reliability of sealing; Owing to using the ring slider of tin bronze alloys casting between the injection loop of gear-box inside and input planet carrier, tin bronze alloys has by force good castability and machinability, in atmosphere and fresh water, there is good corrosion resistance, can ensure can not cause because of the wearing and tearing of slide block emptying between injection loop and input planet carrier, guarantee that the oil pressure of lubricant oil is normal.
