It is the service life of motor operation, external at present to beat 0.09mm's on gas using on piston and displacer main body and cylinder contact surface
Aperture installs air throttle in the both ends of the surface of compression chamber, a part of gas of compression chamber in operation is made to squeeze into piston and displacer
In piston and displacer cylindrical edge gas blanket is generated in cavity to achieve the effect that pneumatic bearing, but this way meeting
Certain acting loss is generated, and machining small can destroy the cylinder of piston and displacer on piston and displacer cylindrical body
Degree.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of piston of Stirling-electric hybrid and the Pneumatic floating knots of displacer

Meter makes gas generate gas shield by the compression ratio of gas while acting in piston and displacer and cylinder, makes piston
And the stable performance of displacer is high, mechanical efficiency is big, and the service life is long.
The technical solution adopted by the present invention to solve the technical problems is: providing the piston and displacer of a kind of Stirling-electric hybrid
Pneumatic floating structure, including cylinder, displacer and piston, the piston is located in cylinder and axially synchronous past with displacer
Movement is returned, is axially connected between the piston and displacer by mobile bar, which is characterized in that the piston and displacer
There are gap between the inner sidewall of cylinder, the one end of the displacer far from mobile bar is the arc surface of middle part protrusion, institute
Be provided with arc transition between the cylinder side wall of the arc surface and displacer stated, the end face of the piston and displacer it is another
One end end face is plane, and air-flow guiding circular arc portion is disposed between the plane and piston or the cylinder side wall of displacer.
As a supplement to the technical solution of the present invention, the arc radius in the air-flow guiding circular arc portion by
It is cumulative greatly until tangent with the cylinder side wall of piston or displacer.
The utility model has the advantages that the present invention relates to the Pneumatic floating structure of a kind of piston of Stirling-electric hybrid and displacer, piston body with
Displacer is made into different arc surface fabrication designs in each connecting portion of cylinder, makes gas in piston and displacer and cylinder
Gas shield is generated by the compression ratio of gas while acting, keeps piston and the stable performance of displacer high, mechanical efficiency
Greatly, the service life is long；The joint face of piston and displacer and cylinder is processed into different circular arcs according to the design of gas compression operating ratio and connects
Junction avoids the technique punched on piston body and displacer cylindrical body, when increasing the sliding property of component and reducing assembly
Scratch；It is small that part shapes difficulty, operation easy to assembly.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Figs. 1-2, the technical solution adopted by the present invention to solve the technical problems is: providing a kind of Stirling-electric hybrid
The Pneumatic floating structure of piston and displacer, including cylinder 3, displacer 1 and piston 2, the piston 2 and displacer 1 are located at
It synchronizes in cylinder 3 and axially and moves back and forth, be connected between the piston 2 and displacer 1 by the way that mobile bar 7 is axial, it is described
There are gap between piston 2 and displacer 1 and the inner sidewall of cylinder 3, during described one end of displacer 1 far from mobile bar 7 is
The arc surface 5 of portion's protrusion is provided with arc transition 4 between the arc surface 5 and the cylinder side wall of displacer 1, described
The end face of piston 2 and the other end face of displacer 1 are between plane, the plane and piston 2 or the cylinder side wall of displacer 1
It is disposed with air-flow guiding circular arc portion 6.
The arc radius in the air-flow guiding circular arc portion 6 is gradually increased until the cylindrical side with piston 2 or displacer 1
Wall is tangent, and the variation of arc radius makes the radian in air-flow guiding circular arc portion 6 gradually slow down, and has good water conservancy diversion and gas compression
Effect.
As a kind of embodiment of the invention, when in use, piston 2 and displacer 1 will do it moving back repeatedly
Air-flow can first enter the gap between displacer 1 and cylinder 3 from arc surface 5 and arc transition 4 when moving, and move
In, the gas in gap can be played the role of air bearing by compression, similarly, air-flow also can by air-flow guiding circular arc portion 6 into
Enter into the gap between piston 2 and cylinder 3, plays the role of air bearing.
The configuration of the present invention is simple, handling ease, piston body are made into different circles in each connecting portion of cylinder from displacer
Curved face processing design makes gas generate gas by the compression ratio of gas while acting in piston and displacer and cylinder and protects
Shield keeps piston and the stable performance of displacer high, and mechanical efficiency is big, and the service life is long.
