Description

Modularization driftage pitch drive
Technical field
The present invention relates to a kind of wind-powered electricity generation reduction box, more particularly to a kind of Split moduleization driftage pitch drive.
Background technology
The Main Function of wind power yawing gear-box be by the swing pinion engaged transmission in output gear and blower fan so that The direction of cabin is adjusted, fan engine room is directed at wind direction all the time and is substantially utilized wind-force.General speed than i be 900 ~ 3000.The Main Function of variable propeller gearbox is the engagement by gear ring in output gear case and blower fan, adjusts blade and wind Angle between realizes that wind wheel has a constant rotational speed to wind-driven generator, and then controls the power output of blower fan.General Speed is 100 ~ 350 than i.Generally in normal R ＆ D design, although variable propeller gearbox is similar with Yaw gearbox structure, Due to speed than and bearing capacity difference, each other the overwhelming majority can not borrow so that gear-box species is various, without unification Module and series, simply unicity ground design and produce, so as to cause the waste of ample resources.And become oar tooth in driftage In roller box, because working environment and operating mode are substantially more severe so that gearbox seals failure causes oil leak, even results in overall tooth Roller box and driftage pitch-controlled system failure often occur.
China Patent No. CN201010174499.X provides a kind of wind power generation three-piece cycloidal variable propeller reducer, by there won't be any problem Star and cycloid slow speed turbine stage are constituted, and install Che Shi sealing rings to improve sealing before slow speed turbine stage output shaft support bearing.China Patent No. CN201420168925.2 discloses a kind of Fuel Tanking Unit for wind turbine gearbox of going off course, by driftage wind-powered electricity generation Gear-box is provided with " L " shape support and oil storage kettle, advantageously reduces air pressure at a high temperature of driftage wind turbine gearbox, improves seal Service life.Still it is necessary for an integrally-built traditional concept without departing from Yaw gearbox or variable propeller gearbox.Even if Leakage is solved, once break down there is still a need for integral demounting.
Based on above reason, the bridge between driftage and variable propeller gearbox how is erected, form wind power yawing variable-pitch gear The series of modules of case, while the sealing and follow-up maintainability that strengthen gear-box turn into the technology hardly possible paid close attention to this area Topic.The content of the invention
It is an object of the present invention to be directed to a series of technological deficiencies that existing integration driftage variable propeller gearbox is present, there is provided A kind of modularization driftage pitch drive.
