Description of the invention (&); Balancer for vibration. In addition, a connector is provided to inject an operating gas into a crank chamber and a buffer chamber (a space on the back side of a piston in a compression cylinder and an expansion cylinder) of such a Stirling machine such as a Stirling refrigerator. The coupler can be connected to a supply source of the actuating gas to inject the actuating gas into the inside. The pressure sensor system, which also doubles as a pressure regulator, is mounted on the mounting block in a releasable manner through a pressure sensor mold (refer to Figure 7B of a conventional example described later). The connector is filled with a working gas. In the Stirling refrigerator, oil mist rises from the crank chamber along the piston rod, that is, there is a problem that the oil rises. This oil rising system, when oil and oil mist enter the cylinder, it will adhere to the inner surface and affect the sealing of the piston. It will not only reduce the durability and reliability, but also supply the compressed air and the oil first. The compressed gas utilization device, the compressed gas utilization device, and various parts processed by the device have an adverse effect. To solve this problem of oil rise, the conventional piston rod system is sealed with an oil ring seal. This oil ring seal is generally made of rubber. Although it has been developed from various structures and material surfaces, its sealing performance and durability may not be sufficient. Therefore, the present inventors have proposed a bellows for oil sealing (refer to Japanese Patent Application No. 10-365371) as a rod seal for a Stirling refrigerator. In the invention of Japanese Patent Application No. Hei 10-365371, a metal bellows for oil seal is provided between the space inside the casing of the Stirling refrigerator and the compression cylinder and the expansion cylinder, which can prevent From the crank chamber along the surface of the piston rod flows into the compression cylinder and the expansion 5 This paper size applies to China National Standard (CNS) A4 specifications (21〇χ 297. ¾) (Please read the precautions on the back before filling this page). 丨 丨—Order --------- line 丨 518395 9087pif.doc / 015 Λ7 B7 V. Description of the invention ($) ~ The oil in the expansion cylinder rises. [Problems to be Solved by the Invention] The balancer mounted on the crank shaft is usually fixed to the mounting surface (generally a flat surface) formed on the crank shaft with screws. However, during the operation, the mounting position is based on the screw. The center is moved (rotated) relative to the crank shaft, which causes a problem that the vibration reduction function is reduced. Although the connector for actuating gas injection is designed to be separated from the main body of the Stirling engine, even so, the Stirling engine will still be affected by its vibration during the operation of the Stirling engine. (Nuts, nuts, etc.) become loose, which causes a problem that the operating gas leaks. In the Stirling freezer, in order to prevent oil from flowing from the crank chamber along the piston rod (oil rises) to the operating cylinders (compression cylinder and expansion cylinder), the cylinders operated by the crank chamber are sealed with oil seals. However, due to the pressure difference between the crank chamber and the actuating cylinder, there are problems such as incomplete oil seals or broken oil seals. Here, it is necessary to periodically check the operating gas pressure of the crank chamber, inject through the coupling, adjust the flare nut attached to the pressure sensor, or adjust the operating gas pressure. It is known that the horn nut is embedded in the pressure sensor mold, and because it is a structure that is not easily accessible (refer to Figure 7B of a conventional example described later), it is used for conservative inspection and repair, etc. It is not easy to adjust the working gas. However, the inventor believes that although the oil-sealed bellows as described in the above-mentioned Stirling freezer is assembled to develop a structure that can further improve the life of the oil-sealed bellows, 6 strokes during reciprocating motion.

Description of the Invention (Order) '' When it moves in the compression direction and extension direction, it is not very good for reducing repeated fatigue. The regenerator is generally composed of fine metal wire mesh, because the deteriorated part of the metal wire mesh will be cut into chips, and it will flow into the heat exchanger, high greenhouse, low greenhouse, etc. with the working gas. The flow resistance of the actuating gas will increase, which will hinder the smooth movement of the piston, causing performance degradation or damage. The space on the cylinder side, the housing, and the space forming the high or low greenhouse are sealed by piston rods such as oil-sealed bellows so that oil does not flow from the crank chamber of the housing into the space on the cylinder side. There is a pressure difference between the operating gas in the housing, so the piston rod seal becomes a poor load, and it may be damaged. In addition, the pressure in the space on the cylinder side is unstable, and the performance of the heat engine is unstable. Generally, the casing is made by casting. However, since the actuating gas inserted into the casing is a gas with a small molecular weight such as He, it is necessary to pay attention to the leakage of the actuating gas from the thin meat of the casting. In particular, when attachment parts such as a terminal box are fixed to the thin meat portion of the casting housing by screws, the thickness of the meat in the screw hole becomes thinner, and the operating gas will pass through the screw hole to make it thinner. The thin meat portion leaks to the outside, so the operating gas pressure in the housing will be reduced, which will cause the problems of the above-mentioned piston rod seal function and durability, and the problem of heat engine performance. The object of the present invention is to solve the problem that the installation position of the balancer will move relative to the crank shaft. The problem is to fix the balancer on the crank shaft and not move the balancer installation position so as not to reduce the anti-vibration function. . The present invention aims to solve problems like this, and its problem is to prevent 7 paper sizes applicable to the Chinese National Standard (CNS) A4 specification (210 X 297) (please read the precautions on the back before filling this page)

Description of the invention (> 丨) Compression of the side stroke S and the reciprocating action of returning to the free length Compared to the occasion, it can be seen that the fatigue is greater. The reason is that the system of repeated compression and expansion occasions has a greater effect on the force of repeated fatigue of oil-sealed bellows than the case of compression only. Based on this finding, in the present invention, as shown in FIG. 8A, the oil-sealed bellows of the length that performs the reciprocating action of the total stroke S from the position of the free length L only to the compression side are used as the compression-side oil-sealed bellows 22 The inflated side oil-sealed bellows 28 are installed separately in the Stirling refrigerator 1 of the present invention as shown in FIG. 2. Next, the features of the structure of the Stirling refrigerator of the present invention having the above-mentioned structure will be described. As shown in Fig. 2, the Stirling refrigerator system of the present invention is provided with a regenerator 30 between the heat-exchanging heat exchanger 29 and the cooling heat-exchanger 31. Figs. 9A and 9B are diagrams illustrating the comparison between the present invention and a conventional example in a regenerator of a Stirling refrigerator. Fig. 9A shows the regenerator 30 of the present invention and Fig. 9B shows a conventional example. . The regenerator 30 is shown in FIG. 2 and FIG. 9A, in a circular-shaped space 452 between the inner tube 24 of the cooling heat exchanger 31 and the cooling heat exchange case 44 on the outside thereof. There are fine metal mesh wires 353. The metal mesh wire 353 is compressed into a fixed shape. In the Stirling freezer system, the pneumatic system frequently reciprocates in the high greenhouse 20 and the low greenhouse 26. At this time, due to the frequent passage of the regenerator, a part of the year-old metal mesh wire 353 will be cut. Cut into chips and enter the high greenhouse 20 or low greenhouse 26 through the grooves 35, 45 with the therapeutic gas. When a problem like this occurs, the fine grooves 35 and 45 will block and make it 24 (please read the precautions on the back before filling this page) • i «Order-丨 Line 丨 Refer to the paper standards applicable in the national standard (CNS) A4 specification (210 x 297 meals) 518395 9087pif.doc / 015 Λ7 B7 V. Description of the invention (&y; y) ^ The flowing resistance of the moving gas becomes larger, which causes the increase of power loss, and because The high-temperature greenhouse 20 or the low-temperature greenhouse 26 flows into the inner clearance between the compression piston 19 or the expansion piston 25 and the compression cylinder 17 or the expansion cylinder 18, which causes the smooth reciprocation of the piston and the damage to the cylinder. In the conventional regenerator system shown in Fig. 9B, since the fine metal mesh wire 353 is filled in the circular space 452, it is impossible to prevent the above-mentioned metal mesh wire from cuttings and the outflow of the operating gas. As shown in FIG. 9A, the regenerator 30 of the present invention is provided with filters 356 at the upper and lower ends of the circular gas space 452 constituting the regenerator 30, that is, upper and lower inlets and outlets 354 and 355, respectively. . This filter 356 is formed with a gap to the extent that the working gas can pass through without cuttings of the metal mesh wire. For example, a thin plate made of a metal mesh with a fine mesh formed of a SUS material is used. Or a thin plate made of a metal or ceramic material and having a fine porous porous sintered material. The Stirling refrigerator of the present invention configured as described above has the following structural features. In FIG. 10A, a terminal box 552 with attached components is mounted on the motor chamber 4 of the housing 2. This terminal box 552 is a terminal section for wiring which receives power from an external power source and transmits power to the motor 6. The present invention is characterized by a fixing structure of accessory parts such as the terminal box 552. FIG. 10A shows a plan view (top view) of the structure 2 of the casing 2 of the Stirling freezer 1 of FIG. 1, and its cross-section along the line A-A is shown in FIG. 10B.

Then, the terminal box 552 is placed on the flat surface 453 at a position shown by an imaginary line in FIG. 10A, and the lower hole 455 of the tapping screw is locked into a tapping screw 458, as shown in FIG. 10B. The imaginary line of the figure is installed.

The enlarged part of Fig. 10B is shown in Fig. 11A. Fig. 11B is a cross-sectional view of the thin meat portion 456. In the flat surface 453 of the housing, a thin meat portion 456 is formed near the position of the lower hole 455 of the tapping screw, which is thinner than the thickness t1 of the other portion of the flat surface 453. In the present invention, as shown in FIGS. 11A and 11B, the mounting flange portion 457 of the terminal box 552 is fixed to the thin meat portion 456 by using the tapping screw 458. Specifically, as shown in FIG. 11C, a lower hole 455 for the tapping screw is formed in the thin meat portion 456, and a lower hole 359 for the tapping screw is formed in the mounting flange portion 457. Then, while screwing the tapping screw 458 from the lower hole 359 of the tapping screw into the lower hole 455 of the tapping screw, it is screwed in, and fixed as shown in FIG. 11D in this manner. In the conventional example, as shown in FIGS. 11E and 11F, firstly, the thin meat portion 456 and the mounting flange portion 457 are formed with screw holes 460 and 461, and the bolts 362 are screwed into the screw holes 460 and 461, so that the terminal box is 552 is fixed to a flat surface 453.

When the expansion piston 25 is slowly moving near the top dead center by 90 degrees, the compression piston 19 is rapidly moved from the vicinity of the middle to the top dead center to perform the compression action of the operating gas. The compressed compressed gas system flows into the fine grooves 35 of the heat radiation heat exchanger 29 through the communication holes 33 and the holes 32 to release heat to the cooling water flowing in the heat radiation path 38. Furthermore, the operating gas system is cooled by the heat and cold stored in the regenerator 30, and flows into the low-temperature greenhouse 26 (expanded space) through the narrow groove 45. When the compression piston 19 moves slowly near the top dead center, the expansion piston 25 moves abruptly to the bottom dead center, and the operating gas flowing into the low-temperature chamber 26 (expansion space) will cause severe expansion and cold and heat. In this manner, the head (so-called cold head) 48 containing the cooling heat exchanger 31 is cooled to a low temperature. Then, the cooling heat exchanger 31 cools the hot and cold refrigerant of the hot and cold utilization equipment connected to the cooling fins 47. When the expansion piston 25 moves from the bottom dead center to the top dead center, the compression piston 19 moves from the middle position to the bottom dead point. The pneumatic system flows from the low-temperature chamber 26 through the groove 45 of the cooling heat exchanger and flows into the regenerator 30. The cold and heat of the working gas is stored in the regenerator 30. The cold / heat system storing heat in the regenerator 30 passes through the heat-generating heat exchanger 29 from the high-temperature greenhouse 20 as described above, and reuses the transmitted working gas to cool it again.

For example, the The cooling and heating medium pipes are cooled or cooled in the cooling and heating equipment. Then, the cooling and heating medium flows into the cooling heat exchanger 31 through the inflow pipe 62 to return to the cooling heat exchanger and is cooled again. The cooling water system sent from the radiator flows into the heat radiation heat exchanger 29 from the inlet 42 and passes through the heat radiation path 38 to cool the working gas. Furthermore, the cooling water system flows into the cooling water path 40 and flows. The periphery of the compression cylinder 17 and the expansion cylinder 18. In this way, the compression cylinder 17 and the expansion cylinder 18 formed inside the cylinder block 15 are cooled from the periphery. After that, the cooling water system flows out of the outflow port 43 and uses the heat sink's The cooling fins cool down and circulate again to the heat-exchanging heat exchanger 29. The buffer tank 51 is formed so that the buffer space 48 and the casing 2 have an equal pressure and absorbs pressure fluctuations in the buffer space 48 and absorbs the pressure in the casing 2 at the same time. Pressure fluctuations, and its impact is less than the buffer function of the buffer space. As shown in Figure 4D, the mounting structure of the conventional balancer 601 without a positioning pin, operates the Stirling freezer 1, and rotates the crank. For the shaft 7 ', the balancer 601 is moved (rotated) relative to the crank shaft 7' with the screw 56 as the center, and its mounting position will cause a problem of movement. As a result, the balancer 601 will be in a proper position to prevent vibration. It cannot move to achieve a predetermined anti-vibration effect.

Description of the Invention (Clever) Because the present invention has the above structure, the compression side and the expansion side oil seal bellows system, by performing the stroke to the compression side and The reciprocating motion returning to the free length can reduce the destructive force applied to the oil seal bellows, reduce repeated fatigue, prevent the oil rise of the Stirling refrigerator, and improve the life of the oil seal bellows. As described above, the conventional regenerator is equipped with a filter. With this simple structure, even if chips of the metal mesh wire are generated due to deterioration over time, the gas and the moving gas will not be removed from the regenerator. The outflow can prevent the increase of power loss caused by the increase in flow resistance caused by the clogging of the heat exchanger for cooling and the heat exchanger for cooling caused by cuttings of the metal mesh wire, and entering between the compression and expansion cylinder inner surface and the piston. Causes various obstacles such as smooth reciprocation and cylinder damage. Since the present invention is structured as described above, even if the accessory parts are fixed to the thin meat portion constituting the casing formed by the casting of the Stirling machine with screws, the operating gas can be prevented from leaking through the thin meat portion through the screw holes. As a result, the operating air pressure in the casing is stabilized, the function of the piston rod seal of the oil seal bellows or the like is reduced or the damage is reduced, the operation performance of the Stirling engine is stabilized, and the life is increased. ___ 32 This paper applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page) · -------- Order ----- ---- Line 1 ·! 1 ---------------
