Embodiment 1

[0035] use Figure 1 ~ Figure 7 The embodiment 1 of the present invention is described.

[0036] figure 1 It is a plan cross-sectional view showing the shaft through scroll compressor of the scroll-type fluid machine of this embodiment, and figure 2 The B-B section is equivalent. figure 2 Yes figure 1 The longitudinal section view is with figure 1 The A-A section is equivalent.

[0037] In these figures, the compression mechanism unit 1 is composed of a frame body 7, a fixed scroll 2 attached to the frame body 7, an orbiting scroll 3 meshed therewith, and the like. In a hermetic compressor, usually the frame 7 is fixed to a hermetic container (not shown), and the fixed scroll 2 is fixed by fixing bolts 8 passing through a plurality of cavities 2e provided in the outer periphery of the fixed scroll 2 On the frame 7.

[0038] The fixed scroll 2 is provided with a mirror plate 2b, a scroll-shaped coil 2a erected on the mirror plate 2b, a suction port 2c provided on the outer peripher...

Embodiment 2

[0053] Next, use Figure 8 ~ Figure 10 Example 2 of the present invention will be described. This embodiment shows an example of applying the present invention to a scroll-type fluid machine having a structure in which the crankshaft does not penetrate the orbiting scroll member. In these figures, the parts assigned the same reference numerals as in the above-mentioned Example 1 indicate the same or equivalent parts. In this embodiment, the orbiting scroll 3 is erected on one side of the mirror plate with a scroll-shaped winding plate, and a orbiting bearing 3c for driving the orbiting scroll is provided near the center of the opposite surface (back side). The crank part of the crankshaft is inserted in the orbiting bearing 3c.

[0054] Figure 8 Is equivalent to Example 1 Figure 5 The figure with Figure 5 In the same way, the center Om of the orbiting scroll 3 is aligned with the center Of of the fixed scroll, and the orbiting scroll 3 is overlapped with a one-dot chain line...

Embodiment 3

[0058] Next, use Picture 11 and Picture 12 Example 3 of the present invention will be described. In these figures, the parts assigned the same reference numerals as in the above-mentioned Example 1 and Example 2 indicate the same or equivalent parts. Picture 11 It is a top sectional view of the scroll type fluid machine of this embodiment, Picture 12 Is equivalent to Picture 11 A longitudinal section view of the E-E section. In the above-mentioned embodiments 1 and 2, the inflow of the working fluid into the compression mechanism adopts the longitudinal suction structure that enters the suction port of the fixed scroll from the axial direction, but in this embodiment, the present invention is applied to the fixed scroll A scroll-type fluid machine of a horizontal suction structure in which the axis of the scroll 2 is perpendicular (radial) is provided with a suction port 2c.

[0059] Compared with the vertical suction structure, the horizontal suction structure has the advan...

Abstract

The invention discloses a vortex type fluid machine and an assembling method thereof, wherein the device is capable of easily and properly engaging a coil plate of a rotary vortex disc with a coil plate of a fixed vortex disc so as to improve energy efficiency. The vortex type fluid machine comprises the fixed vortex disc (2) and the rotary vortex disc (3), wherein the fixed vortex disc is provided with a vortex-shaped coil plate on a mirror plate; the rotary vortex disc is provided with the vortex-shaped coil plate which is engaged with the coil plate of the fixed vortex disc so as to form a compression chamber, and capable of convolution without auto-rotating. A positioning hole (3d) for mounting a positioning pin (4) in the case of assembling is arranged on a coil plate extension wire near a coil plate extremity coil part (3ab) of the fixed vortex disc; an extremity coil circular arc part (2ab) buckled with the positioning pin in the case of assembling is arranged on the coil plate extremity coil part of the fixed vortex disc; and the centre of the positioning hole and the centre of the circular arc of the extremity coil circular arc part are approximately accordant when being assembled in the case that the centers of the fixed vortex disc and the rotary vortex disc are accordant.

Description

Technical field [0001] The present invention relates to a scroll fluid machine using refrigerant, air and other compressible fluids, and is particularly suitable for use in shaft-through scroll compressors. Background technique [0002] As a conventional example of a shaft-through scroll compressor having a structure in which the crankshaft passes through the orbiting scroll, Japanese Patent No. 3170111 is described. The scroll compressor with this structure has the advantage of not generating a torque that causes the orbiting scroll to tilt because there is a bearing at a position where the gas load that operates the orbiting scroll is applied. Therefore, it is characterized in that it is possible to suppress the so-called oscillation motion that occurs when the orbiting scroll is tilted, and to maintain the tip clearance of the wrap plate uniformly, thereby reducing internal leakage and achieving high performance. [0003] Furthermore, in the above-mentioned through-type ...
