2. Description of the Related Art In order to understand the present invention, first, the non-contact rotary machine will be described. In the various non-contact rotary machines shown in FIG. 1, the rotor on the upper stage side in FIGS. 1 (a) to 1 (f) is in close contact with the outer peripheral surface of the fixed hollow body 3 fixed to the outside of the rotation center body 6. However, it is configured to have the blade 1 that rotates integrally with the rotation center body 6 (see FIG.
In (d), the rotor on the lower stage side has the same structure), and the rotors on the lower stage side are in non-contact with each other and are synchronously rotated in opposite directions by a synchronous gear (as a typical example, Figure 1 depicting a side view of 1 (a)
(See also (b)). In this case, the rotation center body 6 is press-fitted into the blade side plate 2 integrally formed with the blade 1 so that the blade 1 and the rotation center body 6 rotate integrally.
The outer peripheral surface of the rotor on the lower stage side is brought into close contact with the fixed hollow body 3, and it is desirable to form a cutout portion 5 in the fixed hollow body 3 so that the rotor is brought into close contact with the fixed hollow body 3 to improve the sealing performance. Line C of the upper rotor is line l of the lower rotor.
These non-contact rotary machines according to the present invention function as pumps or expanders, although they are created by the tips of the rotors (points or small roundness). Since it functions as an expander (rotation is reversed), the case of functioning as a pump will be described. The fluid sucked into the working chamber 8 from the passage 9 is compressed according to the rotation of the rotor, and the opening / closing port 7 is connected to the communication port 4.
When they are communicated with each other, they are discharged into the rotation center body 6 through each of them. However, in FIG. 1 (e), the fluid in the working chamber 8 is discharged to the discharge side through the reed valves 10 and 10 '.
In FIG. 1F, the working chamber 8 communicates with the discharge side from the maximum volume state. Now, in constructing the rotor having the blade 1 and the rotation center body 6 in the non-contact rotary machine as described above (for example, the one shown in FIG. 1A) is used, the blade is made as shown in FIG. An integrally molded product by casting or the like 1 '(corresponding to the blade 1 if processed into a predetermined size) and 2' (corresponding to the blade side plate 2 if processed into a predetermined size) corresponding to the blade side plate Then, the back surface of the blade side plate 2'of the workpiece manufactured as this integrally molded product is flatly machined and then mounted on the table of the machine tool as shown in the drawing to machine the hole 6 ". At the same time, each part of the workpiece is machined to a predetermined size, and the rotary center body 6 which has been machined to a final size in advance as indicated by a chain double-dashed line is press-fitted into the hole 6 ″ to be fastened, and thus the manufacturing is performed. Be done. However, with such a construction method, there is no choice but to process each part of the work piece with a tool such as an end mill, and it is not possible to adopt an efficient processing method such as broaching (blade). As can be seen from the case of machining the side surface of the blade 1'corresponding to the blade 1'and the surface of the blade 2'corresponding to the blade side plate, the blade 2'corresponding to the blade 2'obstructs the broaching process. Is).
Further, since the rotation center body 6 is integrally and joined after finishing the machining of each part of the work piece, each part of the work piece is indirectly positioned and machined with respect to the central axis of the rotation center body 6. After the rotation center body 6 is press-fitted into the hole 6 ″ to be fastened, and then each part is machined with the center axis of the rotation center body 6 as a reference, each part of the workpiece is directly positioned and machined. However, the rotation center body 6 interferes with the processing), and there is a drawback that the processing accuracy is reduced.

2A to 2E are views for explaining a method of constructing a rotor having blades and a rotating center body of a non-contact rotary machine according to the present invention (as a typical example, FIG. 1 (a), but can be similarly applied to other ones. First, as shown in FIG. 2 (a), one corresponding to a blade 1 '(a blade 1 is obtained by processing to a predetermined size). ) And 6'corresponding to the rotation center body (which becomes the rotation center body 6 if processed to a predetermined size) are manufactured as an integrally molded product by casting, forging, etc. (each is manufactured separately). Then, don't combine them by bolts or welding). In this case, the material is cast steel, forged steel, or the like. Next, center holes are correctly drilled in both ends of the rotating body 6'which is equivalent to the center of rotation 6 ', and as shown in FIG. 2B, the center holes provided in the machine tool such as a lathe are centered in the respective center holes. Jigs 12, 12 '(called center on lathe)
Is inserted to support the workpiece from both ends, and each part of the object 6'corresponding to the center of rotation is machined to a predetermined size. In this case, the parts l 1 and l 4 can be easily machined with a tool such as a cutting tool, but the part l 2 has a blade equivalent 1 ', so it is machined with the tool 14 shown in FIG. Good (The inner peripheral surface of the cutting edge 13 corresponds to the center of rotation 6 ', and the outer peripheral surface of the cutting edge 13 corresponds to the blade 1' Be done). The portion of l 3 can be processed in the same manner. Further, the outer peripheral surface of the blade 1'corresponding to the blade is machined, the workpiece is held by a chuck, and the inner peripheral surface of the blade 6'corresponding to the rotation center body is machined. Then, the workpiece is removed and attached to the broaching machine, and the blade side surface of the blade 1'corresponding to the blade is machined by the broaching tool (machined as lines c and c'in FIG. 1 (a)). In this case, when attaching the work piece, a centering jig provided on the broaching machine (not particularly shown,
Positioning is performed by inserting a centering jig 12, 12 'shown in FIG. 2B). In the above description, each part of the workpiece is machined on the basis of the central axis (center axis determined by the centering jigs 12 and 12 ') that is determined to be the central axis of the rotating center body 6'. Is done. Thus, a rotor having the blade 1 and the rotation center body 6 is constructed, which is shown in FIG. Figure 2
In the XX 'cross section of (d), 15 is a cylindrical surface which is in close contact with the outer peripheral surface of the rotor of the mating partner (the lower rotor in FIG. 1 (a)), and the outer diameter of which is the rotational center body 6. The diameter is larger than the outer diameter, and is smaller than the outer diameter of the fixed hollow body 3 when the cutout portion 5 is formed. The cylindrical surface 15 is preferably processed simultaneously with a broaching tool when broaching the blade side surface of the blade 1 (portions corresponding to the lines c, c '). Reference numeral 16 denotes a fixed hollow body insertion portion into which the fixed hollow body 3 is inserted when the rotor is assembled as shown in FIG. still,
The YY 'section is the same as the ZZ' section. In this way, the blade 1 and the rotation center body 6 are located at the intermediate position of the blade 1 and project from the outer circumference surface of the rotation center body 6 and have a cylindrical surface 15 which is in close contact with the rotor outer circumference surface of the mating rotor. The rotor having the blades 1 and the rotation center body 6 is constructed by processing so as to have a structure in which they are integrally connected. Next, in FIG. 2 (a), a kerf 11 is formed in a work piece in which a blade-corresponding blade 1'and a rotary center body 6'are manufactured as an integrally molded product. If it is convenient for casting or the like, it may not be formed as shown in FIG. That is, the fixed hollow body insertion portion 16 of FIG. 2D can be easily obtained by the tool 14 shown in FIG.
Is processed, and the processing margin is slightly increased. FIG. 3 shows a diagram in which the rotor having the blade 1 and the rotation center body 6 constructed as described above is incorporated in a non-contact rotary machine.

The present invention has the following advantages over the prior art. According to the present invention, the blade 1 and the rotation center body 6 are integrally and coupled at the intermediate position of the blade 1, and the blade side plate 2 of the related art is removed, so that the blade side surface (lines c, c ' For processing (corresponding part), broaching is possible (it is impossible to use the blade side plate 2 as a hindrance in the past, so a processing method with an inefficient end mill must be adopted), which is extremely efficient. Can provide a rotor construction method suitable for mass production. According to the present invention, the blade side plate 2 is removed and the blade 1 and the rotation center body 6 are integrated and coupled, and the central axis of the rotation center body 6 (which serves as the rotation center axis of the rotor) is consistently provided. Since each part can be processed with reference to, each part is directly positioned and processed with respect to the central axis of the rotation center body 6, and therefore high processing accuracy can be obtained (conventional method). In Fig. 5, the rotation center body 6 ─ which is an obstacle to tools such as an end mill for the sake of processing needs to be integrated and joined after each part is machined, and as a result, each part has a central axis of the rotation center body 6. For that will be processed indirectly positioned). In FIG. 1B, since the blade 1 receives the pressure of the fluid and the centrifugal force, it is considered that it is a beam that receives an evenly distributed load with one end fixed as shown in FIG. 4A. The maximum deflection is the axial length of the blade 1. If it is l, it is proportional to the fourth power of l. Therefore, when 1 is lengthened, the maximum deflection of the blade 1 rapidly increases, and the gaps between the blade 1 and the inner peripheral surface of the casing and between the blade 1 and the outer peripheral surface of the fixed hollow body 3 must be increased. , Fluid leakage loss increases. In the present invention, as is apparent from FIG. 3, since the blade 1 is integrally and coupled with the rotation center body 6 at the axial intermediate position of the blade 1, the beam shown in FIG. If the axial length l is the same as the conventional one, the maximum deflection is significantly reduced, and if the maximum deflection is the same, then
Can be made longer (more than double). Therefore, it is possible to reduce the leakage loss of the fluid and improve the volumetric efficiency, and to lengthen l to increase the capacity of the non-contact rotary machine (a large capacity machine can be manufactured).
