The present invention provides a Stirling cycle machine, which includes a casing, a cylinder placed in the casing, a displacer 8 , a piston 12 , a first spring 23 and a second spring 22 . The cylinder includes a connected cylinder head cover 6 and a lower part, and a displacer 8 is placed on the cylinder head cover 6 and can reciprocate along the cylinder head cover 6 . The piston 12 is placed at the bottom of the cylinder and can reciprocate along the bottom of the cylinder. The displacer 8 is connected with the first spring 23 , and the piston 12 is connected with the second spring 22 . Cylinder head cover 6, permanent magnet insert 15 are made of PC plastics. The displacer 8 and the piston 12 are made of polyphenylene sulfide (PPS) resin. The technical solution of the present invention uses materials with high hardness, high temperature resistance and wear resistance. Through high-precision machining, the internal movement of the motor without lubricating oil can be maintained at high speed, and the motor can maintain a consistent expansion coefficient when it is heated or cooled. , reduce the friction of the moving parts inside the motor, thereby improving the production efficiency of the whole machine.
Description
technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a Stirling cycle machine, in particular to a Stirling cycle machine such as a Stirling cycle refrigerator. Background technique [0002] Different from the traditional refrigeration theory, the Stirling cycle refrigeration theory is a more efficient thermodynamic theory. The traditional refrigeration cycle is based on the transformation between different forms of the refrigerant medium, while the Stirling cycle refrigeration is a pure gaseous process. With the continuous development of new materials and new technologies and the increasing shortage of petroleum resources, Stirling cycle refrigerators have been paid more and more attention by those skilled in the art. [0003] However, the existing Stirling cycler has many accessories, the transfer process is complicated, and most of the accessories are made of different materials, and the expansion coefficients are...
