Description
Technical field
The utility model relates to a kind of special and supporting wind power speed-increasing device of wind-powered electricity generation unit, belong to the transmission of power speed change gear.
Background technique
At present, it is ripe that the technology of utilizing wind-force to generate electricity has been tending towards, as the wind-powered electricity generation unit of present 250KW, has blade to bear wind-force on this wind-powered electricity generation unit and rotating speed is passed to generator by the wind-force transmission shaft.Usually rotating speed is high more, and the generating efficiency of generator is just high more, and the wind-force rotating speed that blade is accepted is not high, and therefore, directly the wind-force rotating speed being reached generator, to carry out the effect of wind-power electricity generation not very good.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of tilting speedup box of wind-powered electricity generation that is connected between wind-force transmission shaft and the generator, it is with bearings input shaft, jack shaft and output shaft to be arranged respectively in a casing, there is a pair of gear pair engagement to link to each other between three successively respectively, the input end of its input shaft and wind-force propeller shaft couplings, output shaft connects with generator by coupling.
Each is supported in the integrated type casing with two selfaligning roller bearings at least for described input shaft, jack shaft and output shaft, and cabinet wall is furnished with stiffening rib.
With the tapering Desing of Interference Joint input gearwheel is arranged on the described input shaft, a spacer ring is housed between this gearwheel and the rear end bearing, and is provided with bearing housing between input end bearing and the casing.
The described intermediate speed pinion that is fixed with and imports the gearwheel engagement on jack shaft also has gear broad in the middle with the tapering interference fit joint on the intermediate speed pinion limit, between this gear broad in the middle and the rear end bearing spacer ring is housed.
Gear engagement described and broad in the middle has output shaft gear, between the bearing of output shaft and the axle excess axle bearing sleeve is housed, and output shaft connects with generator by a tyre type elastic coupling flexible coupling.
The end cap of described input shaft and output shaft all adopts disc to get rid of oil seal.
The utlity model has compactness rational in infrastructure, the speedup effect is obvious, and long service life is overhauled characteristics such as easy to maintenance, safe and reliable.
