    Oldham Ring of Scroll Compressor
    The present invention relates to an old ham ring of a scroll compressor, and more particularly, by simplifying the old ham ring structure of the scroll compressor, the manufacturing process is easy, and the old ham ring of the scroll compressor is simplified the turning scroll and frame manufacturing process It is about.
    In general, scroll compressors are being used as compressors in room air conditioners or automotive air conditioners due to high efficiency, low noise, compactness, and light weight. Such a scroll compressor is used to compress gaseous gas by rotating a pair of opposed scrolls.
    1 is a longitudinal sectional view showing an internal configuration of a general scroll compressor to which the present invention is applied.
    As shown in the drawing, above the sealed container-shaped main body 10, the suction pipe 11 and the discharge pipe 12 communicating with the inside and the outside thereof to suck and discharge the refrigerant are spaced apart by a predetermined distance. . The suction pipe 11 and the discharge pipe 12 are installed in communication with the indoor unit (or evaporator) and the outdoor unit (or condenser) side of the refrigeration cycle (not shown) and the refrigerant tube.
    The top plate 20 and the sub plate 30 are installed above and below the inside of the main body 10.
    The top plate 20 has an open center and its outer circumferential surface is integrally formed above the inner circumferential surface of the main body 10, and divides the inside of the main body 10 into the suction chamber 13 and the discharge chamber 14.
    In addition, the fixed scroll 40 is fixed to the lower side of the top plate 20, the rotating scroll 50 is fitted rotatably below.
    The fixed scroll 40 is provided with an involute blade 41 at the lower side thereof, and a discharge port 42 penetrating the opening formed in the top plate 20 is formed at the center thereof.
    On the other hand, the swing scroll 50 is provided with an involute blade 51 on the upper side to correspond to the blade 41 installed in the fixed scroll (40).
    In addition, the lower side of the orbiting scroll 50 is supported by the frame 60.
    The swinging scroll 50, as shown in Figure 2, is provided with an involute blade 51 on the upper side to correspond to the fixed scroll 40, the guide groove 52 is provided on the lower side.
    In addition, the turning scroll 50, the lower side edge side is supported in the circumferential direction and the upper edge of the edge of the frame 60, the support groove 61 is provided between the old ham ring 70 is disposed therebetween.
    That is, the old ham ring 70 is provided with a guide protrusion 71 which is inserted into and supported by the guide groove 52 formed in the swing scroll 50 at an opposite position of the old ham ring 70, and the guide protrusion 71 On the lower orthogonal side, another guide protrusion 72 supported by the guide groove 61 formed on the upper side of the frame 60 is provided (see Fig. 2).
    On the other hand, a motor 80 that is a driving source of the turning scroll 50 is installed below the turning scroll 50.
    That is, when power is applied to the motor 80, the orbiting scroll 50 provided at the upper end thereof is rotated.
    At this time, the guide protrusions 71 and 72 provided on the upper and lower sides of the old ham ring 70 are upper side of the guide groove 52 and the frame 60 provided below the turning scroll 50. Since each of the guide grooves 61 provided in the guide grooves 61 is fitted therein, the pivoting scroll 50 provided by the driving of the motor 80 is in a state in which the rotational force is blocked. Likewise, each blade 41, 51 is idle while forming only a small circle while maintaining only the engaged shape.
    Therefore, the low-temperature low-pressure gas gas sucked through the suction pipe 11 after the heat exchange in the indoor unit (or the evaporator), not shown, is rotated with the fixed scroll 40 as shown by the one-point arrow of FIG. After flowing through the inlet of the flow path formed by the involute blades 41 and 51 provided in the scroll 50, the turning scroll 40 is turned, as shown in b) to d) of FIG. It is compressed at high temperature and high pressure in the compression chamber 43 while gradually reducing its sealed area.
    As described above, the refrigerant compressed at a high temperature and high pressure is discharged into the discharge chamber 14 through the discharge port 42 formed through the fixed scroll 40, and then the outdoor unit not shown through the discharge tube 12. (Or a condenser) is discharged.
    However, the following problems occur in the old ham ring of such a general scroll compressor.
    That is, the old ham ring 70 is processed separately so that the guide protrusions 71 and 72 are integrally formed at the upper and lower orthogonal positions, and the turning scroll 51 and the frame 60 In order to precisely process the separate guide grooves 52 and 61 into which the guide protrusions 71 and 72 are fitted, the manufacturing process is cumbersome and the productivity is lowered. There was a rising problem.
    In addition, a separate guide groove 61 on the lower side of the turning scroll 50 and the upper side of the frame 60 so that the guide protrusions 71 and 72 formed on the upper and lower sides of the old ham ring 70 are fitted. Another problem that raises the price of scroll compressors is that their manufacturing process is also cumbersome since they have to be formed.
    Therefore, the technical problem to be achieved by the present invention, that is, the object of the present invention is to solve the problem of the old ham ring of the conventional scroll compressor, by simply simplifying the structure of the old ham ring, it is easy to manufacture and productivity It is to provide an old ham ring of a scroll compressor that can improve and, accordingly, lower the manufacturing cost of the scroll compressor.
    Another object of the present invention is to provide an old ham ring of a scroll compressor that facilitates the manufacture of a swing scroll and a frame on which the old ham ring is supported by simplifying the structure of the old ham ring.

    Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving this object will be described in detail.
    1 is a cross-sectional view of a general scroll compressor to which the present invention is applied, and the same parts and members as in the prior art will be described with the same reference numerals, and FIGS. 4 to 5 illustrate the first and second implementations of the old ham ring according to the present invention. It is an exploded perspective view for an example.
    As shown in the figure, the top plate 20 and the sub plate 30 are disposed above and below the body 10 of the scroll compressor according to the present invention.
    Below the top plate 20, fixed scrolls 40 and pivoting scrolls 50 having blades 41 and 51 on the lower side and the upper side, respectively, are correspondingly engaged. A discharge port 42 and a compression chamber 43 are formed at the inner center of the fixed scroll 40, and the lower side of the swing scroll 50 is supported upward by the frame 60.
    Meanwhile, an old ham ring 70 is interposed between the swing scroll 50 and the frame 60, and a motor 80 that is a driving source for rotating the swing scroll 50 below the frame 60. These configurations are similar to the internal configuration of a typical scroll compressor.
    4 to 5, the old ham ring 70 is supported on the lower side of the turning scroll 50 and the upper side of the frame 60 on at least one side thereof. A pair of guide protrusions 72 are disposed, and a single guide protrusion 71 is provided on the other side.
    Preferably, in order to satisfy the above conditions, a single guide groove corresponding to the protrusion is formed on one side of the lower side of the turning scroll 50 or the upper side of the frame 60 on which the single guide protrusion 71 is supported. (61) is formed, and the other side of the upper side is to be provided with a flat surface.
