Description
Technical field
The present invention relates to Francis turbines, especially " planetary gear Francis turbine ", belong to fluid machinery.
Background technology
Chinese Patent Application No.：201210524582.4 " method for improving pressure pulsation of mixed-flow type pump turbine ",
A method of improving pressure pulsation of mixed-flow type pump turbine, including suitable movable guide vane number Z g of selection, determining conjunction
The methods of the guide vane pitch circle diameter D g of reason and determining rational runner to fixed edge distance δ, to reach improvement mixed-flow
Pressure fluctuation before runner after pump turbine guide vane.Chinese Patent Application No.：200510086922.X a kind of " H-type runner runner
Francis turbine ", above Francis turbine in two patent applications be all to have guide vane before runner to obtain circular rector,
Runner directly links together with main shaft synchronous rotary, runner and the transmission ratio that main shaft is mostly 1 to 1, so the body of generator
Product is larger, and generating efficiency is relatively small.
Invention content
In order to improve Francis turbine series, the present invention tries hard to provide a kind of planetary gear Francis turbine, can improve
Transmission efficiency reduces cost of manufacture, reduces the volume of the hydraulic turbine.
The technical solution adopted by the present invention to solve the technical problems is：Planetary gear Francis turbine, end cap and base ring
Between have guide vane, between main shaft and runner, use planetary gear train transmission, there are one runner between end cap and base ring, runner
End face and the end face of end cap between be provided with planetary gear train, the centre of planetary gear train links together there are one gear with main shaft
And energy rotating Vortex, it is sun gear；The outer ring of planetary gear train is gear ring there are one internal gear, and gear ring is fixed on the end face of runner,
It links together with runner and can rotating Vortex；Gear between sun gear and gear ring is planetary gear；The characteristics of this planetary gear train
It is to have the circular hole coordinated with main shaft among runner, runner can be rotated with gear ring around main axis, sun gear, the axis of planetary gear
Be fixed on the end face of end cap, planetary gear can only rotation, planetary gear and wheel carrier cannot surround main axis.The outer circle of runner around
Axis is evenly equipped with helical blade.
Planetary gear Francis turbine, working method be, it is characterized in that：Enter runner when water forms energy circulation by guide vane
Room acts on the blade of runner and pushes runner rotation；The runner of rotation is rotated together with gear ring, and gear ring drives planetary gear, row
Star-wheel drives sun gear, sun gear to make rotating Vortex with main shaft.
The invention has the advantages that between planetary gear Francis turbine main shaft and runner, planetary gear train is used
Transmission, transmission are mainly characterized by small, large carrying capacity, and stable working improves transmission ratio, the generator of the slow-speed of revolution
The big price of volume is high, and the volume that rotating speed improves generator can reduce, and can improve installation number of units to the limited space of reservoir, reduce system
Cause this.
