Description
Technical field
The utility model relates to a kind of hydraulic variable-pitch transmission gear of wind generating set.
Background technique
Hydraulic variable-pitch transmission gear of wind generating set, mainly effect is to be used for the angle that facings the wind of adjusting vane, reaches the ability that blade receives wind energy that changes.Wind power generating set has three blades usually, and the adjusting at the angle that facings the wind of these three blades is finished by hydraulic variable-pitch transmission gear of wind generating set usually.This hydraulic variable-pitch transmission gear mainly contains three blade bearings, three gearwheels, tooth bar, tooth bar bearing, leverage, servo-hydraulic oil cylinder and link rods.Three blades of wind power generating set are respectively by three uniform being arranged on the wheel hub of blade bearing.The root of each blade is equipped with described gearwheel, and the tooth bar that matches with this gearwheel is installed in the chute of tooth bar bearing and its bearing is arranged on the inwall of wheel hub, and the bottom of each tooth bar one end is provided with allocating slot.Leverage is made up of central gear, link rod, three levers and support, three uniform being arranged on the described wheel hub of support, the middle part of three levers connects with three stand hinge respectively, the outer end of three levers is positioned at the allocating slot of three tooth bar bottoms respectively, the inner end of three levers is positioned at the groove that the central gear periphery is provided with, one end and the central gear of link rod link, and the piston rod of the other end of link rod and servo-hydraulic oil cylinder links.Because said mechanism not only contains leverage, and contains gear and rackwork, so complex structure, weight is big, fault is many.
The model utility content
The technical problems to be solved in the utility model provides a kind of hydraulic variable-pitch transmission gear of wind generating set, and it is simple in structure, weight is little, fault is few.
For solving the problems of the technologies described above, a kind of hydraulic variable-pitch transmission gear of wind generating set that the utility model provides, it contains three blade bearings, servo hydraulic cylinder, joint sleeve, the piston link rod, three blades of wind power generating set are respectively by on the uniform wheel hub that is arranged on wind power generating set of three blade bearings, the piston rod of servo hydraulic cylinder links by joint sleeve and piston link rod one end, the piston link rod can rotate relative to piston rod, also contain thrust disc, connecting rod and track bar, thrust disc is the Y shape and structure that is provided with three poles, around its three poles are uniform, the other end of described piston link rod is arranged on the central authorities of thrust disc, the bottom of track bar is arranged on the bottom of described blade and departs from the blade shaft axis, and an end of connecting rod connects with the pole formation activity of thrust disc, the other end of connecting rod connects with the top formation activity of track bar.
The described track bar that departs from the blade shaft axis and be arranged on the blade bottom, structure is at 45 at grade for the line of its bar heart line and blade shaft axis and blade.
Owing to adopt the thrust disc of Y shape and structure, and thrust disc is connected with the track bar formation activity of the bottom that is arranged on blade by connecting rod, therefore when servo hydraulic cylinder when piston link rod drive thrust disc moves, the end that connecting rod and thrust disc one pole link is made the direct the other end that moves the connecting rod that links with track bar and is then rotated around the shaft axis of blade, thereby drives its angle that facings the wind of blade adjustments.Compared with prior art, not only save leverage, and saved gear and rackwork, therefore simple in structure, in light weight, fault is few and the maintenance convenient.
