Background technique
Fluid coupling is a kind of hydraudynamic drive equipment utilizing the kinetic energy transferring power of work fluid.The critical piece of fluid coupling is two active wheels, in the middle of active wheel, be filled with work fluid.The active wheel be wherein connected with driving shaft is pump impeller, and what be connected with driven shaft is turbine, respectively as power input and power take-off.Driving shaft and driven shaft are arranged on the same axis, and physical dimension is identical, and the blade of some is all housed in active wheel.Certain interval is had, mechanical contact to each other between two active wheels.When main frame drives driving shaft, when pump impeller is rotated, the work fluid in active chamber, under the drive of blade, exports because centrifugal action flows to outer rim by side-entrance in pump impeller, forms high-voltage high-speed liquid stream, rush at turbine blade, make turbine follow pump impeller rotating Vortex.Work fluid flows into pump impeller import again from turbine center, and form circulation, such reciprocation cycle, makes fluid coupling work constantly.In this course, the changes mechanical energy of input is kinetic energy and the potential energy of work fluid by pump impeller, and the kinetic energy of work fluid and potential energy are the mechanical energy exported by turbine, thus achieve the transmission of energy.
The pump impeller of the fluid coupling of prior art and turbine, its blade is fixed, and comprise radial rectilinear and tilting two kinds, when working conditions change, the inclination angle of fixed turbine blade cannot regulate.In order to the change of adaptation condition, current boats and ships adopt adjustable oil-filled amount formula fluid coupling usually, by the object regulating the oil-filled degree of active chamber to change fluid coupling institute's transmitting torque and rotating speed, but its complex structure, the oil charging-discharging time is longer.
Summary of the invention
The purpose of this utility model is to provide can when not changing the oil-filled degree of active chamber, by the adjustable vane type of turbine fluid coupling of one regulating the inclination angle of turbine blade to carry out adaptation condition change.
The purpose of this utility model is achieved in that
A kind of adjustable vane type of turbine fluid coupling of the utility model, comprise pump impeller and turbine, pump impeller is connected with main shaft, turbine is connected with driven shaft, driving shaft and driven shaft are positioned on same axis, work fluid is filled with between driving shaft and driven shaft, the blade of pump impeller is fixed radial straight vertical blade, it is characterized in that: described turbine comprises turbine blade controlling mechanism, turbine output shaft, turbine blade controlling mechanism comprises slide bar, regulon, described regulon comprises gear, tooth bar, adjustable inclination angle turbine blade, adjustable inclination angle turbine blade is arranged on gear, wheel and rack engages, tooth bar connects spoke, regulon is evenly arranged along turbine output shaft circumferencial direction, slide bar also can move along its axis with turbine output shaft is coaxial, slide bar is connected with the spoke of each regulon.
The utility model can also comprise:
1, adjustable inclination angle turbine blade rotates in the scope of 0-180 ° around himself longitudinal axis under rack drives.
Advantage of the present utility model is: the utility model can meet the needs that different operating mode moment of torsion transmits.Compared with adjustable oil-filled amount formula fluid coupling, the governing speed of adjustable vane type of turbine fluid coupling of the present utility model is fast, can the change of adaptation condition fast, and simplify working solution fill oil-releasing mechanism, better to the adaptability of multi-operating mode, and can regulate fast when working conditions change.

Fig. 3 is turbine structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing citing, the utility model is described in more detail:
Composition graphs 1 ~ 3, the pump impeller blade 3 of the utility model is adjustable vane type of turbine fluid coupling is fixed radial straight vertical blade, and turbine blade 4 is dip-adjustable type prismatic blade.As shown in Figures 2 and 3, the turbine blade controlling mechanism of adjustable vane type of turbine fluid coupling, comprises the component such as turbine blade 4, gear 5, tooth bar 6, slide bar 7, spoke 9.Slide bar 7 is coaxial with turbine output shaft 8, and each tooth bar 6 is fixedly linked with slide bar 7 by each spoke 9.Each turbine blade 4 is fixedly linked with each gear 5, can rotate around gear shaft.
Fluid coupling of the present utility model does not need outside recycle oil system, and the work fluid of active chamber can not change in the course of the work.During hydraulic coupler rotor, by push-and-pull slide bar 7, each tooth bar 6 is synchronized with the movement, thus drives each gear 5 synchronous axial system, finally realize the adjustment to each turbine blade 4 inclination angle.When the rotating speed of active wheel 1 and 2 remains unchanged, change the inclination angle of turbine blade 4, the moment of torsion that active wheel transmits will change, thus can regulate the rotating speed of turbine output shaft, and now fluid coupling is equivalent to the effect of speed regulator; When turbine blade 4 place plane is with time axially vertical, namely inclination angle be 0 ° or 180 ° time, now fluid coupling general not transmitting torque, is equivalent to the effect of clutch.
The work fluid of adjustable vane type of turbine fluid coupling of the present utility model, for be surely full of degree type, by a certain amount of working oil liquid sealing in active chamber, not need outside recycle oil system, thus simplifies the structure of fluid coupling.In order to make surely to be full of the effect that degree type fluid coupling can play speed regulator, can play again the effect of clutch, the blade design of turbine is become adjustable inclination angle formula by the utility model.When operating mode changes, blade can be made to be in different heeling conditions by the blade of rotary turbine, thus transmit different moments of torsion, with the change of adaptation condition.
The effect of rack gear is by the slip of slide bar 7 in turbine output shaft 8, is with carry-over bar to move by spoke 9, thus driven gear regulates the inclination angle of turbine blade.By realizing to the adjustment at turbine blade inclination angle the object transmitting different moment of torsion under different operating mode.
A kind of adjustable vane type of turbine fluid coupling of the utility model, be made up of pump impeller 1, turbine 2 and turbine blade incidence regulating mechanism, the inclination angle of turbine blade can be regulated by controlling mechanism.
