Floating structure.
Background technique
The inside of Stirling-electric hybrid is mainly the quick operation of displacer and piston, and running frequency is high, and is integral solder
Oil-free operation is sealed, it is no added lubricant that piston and displacer are run in cylinder, how to accomplish pneumatic suspension to guarantee
It is the service life of motor operation, external at present to be machined 0.09mm using on piston and displacer main body and cylinder contact surface
Aperture, compression chamber both ends of the surface install air throttle, so that a part of gas of compression chamber in operation is squeezed into piston and displacement
In piston and displacer cylindrical edge gas blanket is generated in device cavity to achieve the effect that pneumatic bearing, but this way
Certain acting loss can be generated, and machining small can destroy the circle of piston and displacer on piston and displacer cylindrical body
Column degree.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of piston of Stirling-electric hybrid and the Pneumatic floatings of displacer
Dynamic structure, structure is simple, handling ease, and piston body is made into different arc surfaces in each connecting portion of cylinder from displacer and processes
Design makes gas generate gas shield by the compression ratio of gas while acting in piston and displacer and cylinder, makes to live
Plug and the stable performance of displacer are high, and mechanical efficiency is big, and the service life is long.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of piston of Stirling-electric hybrid and setting
It is interior and axial same that the Pneumatic floating structure of parallel operation, including cylinder, displacer and piston, the piston and displacer are located at cylinder
Step moves back and forth, and is axially connected between the piston and displacer by mobile bar, which is characterized in that the piston with set
There are gap between parallel operation and the inner sidewall of cylinder, the one end of the displacer far from mobile bar is the circular arc of middle part protrusion
Face is provided with arc transition, the end face of the piston and displacement between the arc surface and the cylinder side wall of displacer
The other end face of device is plane, and air-flow guiding circular arc is disposed between the plane and piston or the cylinder side wall of displacer
Portion.
As a kind of supplement to technical solution described in the utility model, the circular arc half in the air-flow guiding circular arc portion
Diameter is gradually increased until tangent with the cylinder side wall of piston or displacer.
The utility model has the advantages that the utility model relates to the Pneumatic floating structure of a kind of piston of Stirling-electric hybrid and displacer, piston
Body is made into different arc surface fabrication designs in each connecting portion of cylinder from displacer, makes gas in piston and displacer and gas
Gas shield is generated by the compression ratio of gas while acting in cylinder, keeps piston and the stable performance of displacer high, acting
Efficiency is big, and the service life is long；The joint face of piston and displacer and cylinder is processed into different circles according to the design of gas compression operating ratio
Arc joint face avoids the technique punched on piston body and displacer cylindrical body, increases the sliding property of component and reduces dress
The scratch of timing；It is small that part shapes difficulty, operation easy to assembly.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figs. 1-2, the technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of Stirling
The piston of machine and the Pneumatic floating structure of displacer, including cylinder 3, displacer 1 and piston 2, the piston 2 and displacer 1
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, institute
There are gap, described one end of displacer 1 far from mobile bar 7 between the piston 2 stated and displacer 1 and the inner sidewall of cylinder 3
For the arc surface 5 of middle part protrusion, arc transition 4, institute are provided between the arc surface 5 and the cylinder side wall of displacer 1
The end face for the piston 2 stated and the other end face of displacer 1 are the cylinder side wall of plane, the plane and piston 2 or displacer 1
Between be 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 an embodiment of the present invention, when in use, piston 2 and displacer 1 be will do it repeatedly
Air-flow can first enter the sky between displacer 1 and cylinder 3 from arc surface 5 and arc transition 4 when moving back and move, and move
In gap, the gas in gap can be played the role of air bearing by compression, and similarly, air-flow can also pass through air-flow guiding circular arc portion 6
It enters in the gap between piston 2 and cylinder 3, plays the role of air bearing.
The utility model structure is simple, handling ease, and piston body and displacer are made into difference in each connecting portion of cylinder
Arc surface fabrication design, so that gas is generated gas by the compression ratio of gas while acting in piston and displacer and cylinder
Body protection keeps piston and the stable performance of displacer high, and mechanical efficiency is big, and the service life is long.
