Abstract
The invention relates to a compression piston structure for a linear integral Stirling refrigerator, which comprises a motor rotor and a piston framework, wherein the piston framework is in a hollow annular structure; a hollow part of the piston framework serves as a reserved space of an expansion machine; the motor rotor is bonded in an annular groove of the piston framework to form a component I; and the component I is arranged in a housing. A wear resistant layer is solidified on the housing to form a component II, and the component I is fixedly connected with the component II in a bonding manner to form the overall annular piston structure. Chamfers are arranged at corners of a groove bottom of the piston framework, and the bottom fin height h is equal a half of the groove depth H. The structure reserves a placement space for the expansion machine of the linear integral Stirling refrigerator, the whole length of the linear integral Stirling refrigerator is reduced, and the structure facilitates application of a compressor and the expansion machine of the linear Stirling refrigerator on a gyro gimbal of a guided missile.
Description
Affiliated technical field
The present invention relates to the structure of compression piston in a kind of linear compressor, be mainly used in the linear sterlin refrigerator of integrated type.
Background technique
At present, sterlin refrigerator mainly is linear compressor with compressor, decompressor and compressor are axial at X, Y and Z() the independent existence on three directions, the decompressor of linear integrated type sterlin refrigerator relies on structural order to be connected with compressor in the Z direction, the decompressor of Split type Stirling refrigerating machine and compressor adopt connection by metal hose, the sterlin refrigerator volume of this spline structure is large, length is long, is unfavorable for rotation, therefore is unfavorable for using at the gyro gimbal of guided missile.Present compression piston is cylindrical piston, is positioned at the central position of compressor axis, can not satisfy compressor axial at Z(with decompressor) needs that overlap of direction.
Summary of the invention
Axial at Z(with decompressor for solving linear integrated type sterlin refrigerator compressor) the locational requirement problem that overlaps of direction, the purpose of this invention is to provide a kind of compression piston structure for linear integrated type sterlin refrigerator, this structure can be axial at Z(with compressor and decompressor) direction partially overlaps, thus volume and the length of dwindling sterlin refrigerator.
The present invention is the technological scheme that its purpose of realization is taked:A kind of compression piston structure for linear integrated type sterlin refrigerator, comprise electric mover and piston skeleton, described piston skeleton is the hollow ring structure, the hollow space of piston skeleton is the headspace as decompressor, and described electric mover is bonded in constituent components one in the circular groove of piston skeleton; Described assembly one places in the shell.
The skin of described shell also is provided with wearing layer, both constituent components two of shell and wearing layer thereof.
The bottom land corner of described piston skeleton is provided with chamfering, and piston skeleton bottom is fin structure, and described fin height is 1/2nd of groove depth, and described chamfering is the fillet take fin height as radius.
Described electric mover is winding or permanent magnet.
Beneficial effect of the present invention:The present invention is that the decompressor of linear integrated type sterlin refrigerator is reserved placement space, shortens the complete machine length of linear integrated type sterlin refrigerator.Being conducive to linear sterlin refrigerator compressor and decompressor uses at the gyro gimbal of guided missile.
