Abstract
The invention belongs to aircraft engine attachment field of mechanical structure design.It is proposed a kind of leverage for realizing division function, including：P1 bellows 1, lever 2, P3 bellows 3, lever 4, bearing 5, screw 6 and axis pin 7；P1 bellows 1 acts on 2 one end of lever, and P3 bellows 3 acts on 4 one end of lever, and lever 2 is connected with lever 4 by screw 6, and 4 other end of lever is connected to by axis pin 7 on bearing 5.Effect can be experienced the power of air pressure before and after compressor thereon by the present invention, be converted into the current signal of compressor, while export mechanical displacement, realize control of the engine to guide vane desired locations.
Description
Technical field
The invention belongs to aircraft engine attachment field of mechanical structure design.
Background technology
It is more using leverage in the mechanical structure of aircraft engine attachment at present, for transferring displacement signal, but its
Function is the multiplication function by lever, i.e., using torque and be zero principle, the transmission of displacement signal is realized, such as Fig. 1 institutes
Show, be the leverage of the multiplication function in aircraft engine accessory power rating, the lever of this type is with simple in structure, but engine
, need to be according to signal before and after compressor to wicket gate control, as input signal, this structure lever can not realize that division signal inputs.
Bellows for it is a kind of experience air pressure after, the pressure sensor of the exportable accurate shifting signal in position is widely used in aviation field.
The content of the invention
The purpose of the present invention is：It proposes a kind of leverage for realizing division function, effect can be experienced compressor thereon
The power of front and rear air pressure is converted into the current signal of compressor, while exports mechanical displacement, realizes engine to guide vane desired locations
Control.
The technical scheme is that：
A kind of leverage for realizing division function, including：P1 bellows 1, lever 2, P3 bellows 3, lever 4, bearing 5, spiral shell
Nail 6 and axis pin 7；P1 bellows 1 acts on 2 one end of lever, and P3 bellows 3 acts on 4 one end of lever, and lever 2 passes through screw with lever 4
6 connections, 4 other end of lever are connected to by axis pin 7 on bearing 5.
Experience pressure before compressor using P1 bellows 1, P3 bellows 3 experiences pressure after compressor, P1 bellows 1 is according to different height
2 arm of force of pressure change lever before the lower compressor of degree, P3 bellows 3 change output displacement according to real-time pressure after compressor.
It is an advantage of the invention that：
Performance is stablized, and control accuracy is high, it can be achieved that division function, bellows 1,3 for it is a kind of experience air pressure after, it is exportable accurate
The pressure sensor of displacement signal, is widely used in aviation field, and regulations and parameters 2,4 structures can will experience air pressure before and after compressor
Bellows power is efficiently converted into the current signal of compressor, with signal output mechanical displacement, realizes the control of guide vane desired locations.
Description of the drawings
Fig. 1 is the structure diagram of multiplication function leverage；
Fig. 2 is the structure diagram that the present invention realizes division function leverage.
Specific embodiment
Realize the design of division function leverage, as shown in Figure 2：A kind of leverage for realizing division function can incite somebody to action
The bellows power of air pressure before and after compressor is experienced in effect thereon, is converted into the current signal of compressor, while exports mechanical displacement, real
Existing control of the engine to guide vane desired locations, which is by P1 bellows 1, lever 2, P3 bellows 3, lever 4, bearing 5, screw
6 and axis pin 7 form lever construction.P1 bellows 1 acts on 2 one end of lever, and P3 bellows 3 acts on 4 one end of lever, lever 2 with
Lever 4 is connected by screw 6, and 4 other end of lever is connected to by axis pin 7 on bearing 5.Before experiencing compressor using P1 bellows 1
Pressure, P3 bellows 3 experience pressure after compressor, P1 bellows 1 according to 2 arm of force of pressure change lever before compressor under different height,
P3 bellows 3 changes output displacement according to real-time pressure after compressor, by the lever mechanism, experiences the current signal of compressor,
So as to export mechanical displacement, guide vane desired locations under total state are controlled.
