。Conventional swirling and driving methods used in scroll fluid devices
The mechanism consists of a bearing tC installed in the center of the orbiting scroll, an eccentric shaft part of the crankshaft serving as the transmission shaft, and an Oldham mechanism that combines linear reciprocating motion, a Scotch chirping type, etc. as an anti-rotation mechanism. I used C. For this reason, a large load is applied to the transmission shaft in a direction perpendicular to the shaft, reducing reliability.In addition, when viewed as a compressor, the rotation speed of the transmission shaft must be increased in order to achieve high speed. The only way to change the volume is to convert the scroll body, and if you want to further control the capacity, you can either change the rotation speed of the transmission shaft, or inject fluid into the chamber during the compression stroke. I had to prepare for it to escape.

２１に押出される。An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. The figure shows a scroll compressor as an example, and the fluid displacement device is composed of an exercise machine 2 in a closed container 1, a fixed scroll member 4 made of a flat plate with an upright spiral horn, and a silkworm orbiting scroll member 5. 3 is stored. Orbiting scroll bearings 16 are provided at 21i11 positions on the flat plate of the orbiting scroll 5, and the eccentric shaft 30 provided at the end of the crankshaft 9 to which the driven gear ID is fixed is inserted into the two orbiting scroll bearings 16, respectively, and the electric motor 2 The 7ζ1 drive gear 14, which is fixed to the drive shaft 8 directly connected to the drive shaft 8, is meshed with the two driven gears 15. , the drive shaft 8 is a main shaft 38 of the main frame 7 and an auxiliary bearing 17 of the intermediate 7 norm 6.
The crankshaft 9 of 2II11 is similarly supported by two upper bearings 18 provided on the intermediate frame 6 and two lower bearings 39 on the main frame A7, and is fixed to the shaft. The driving gear 14 and the driven gear 15 are arranged between the main claim 7 and the intermediate position. The fixed scroll 4, intermediate frame 6, and main frame 7 are mechanically fixed to the closed container 1, and the stator of the electric motor 2 is also fixed to the closed container. The movement e in the direction of the axis of the fifth orbiting scroll is restricted by the fixed scroll 4 and the intermediate frame 6, but the slight movement is limited. The power of the electric motor 2 causes the drive #IJJ gear 14 to rotate at a subordinate radius. 1ml due to this swirling movement.
The closed space formed by the fixed scroll 4 and the orbiting scroll 5 moves from the outside to the inner center, and the fluid in the closed space is compressed. That is, the working driftwood flows into the suction chamber 2o in the outer circumferential space of the fixed scroll through the suction 119 provided in the fixed scroll, and then due to the orbiting movement of the orbiting scroll, a maximum airtight seal is formed between the scroll wraps. The working fluid sealed in the space is compressed to the minimum sealed air of 1 dJ by moving into the compression chamber, and then pushed out from the pressure outlet 12 to the discharge outlet 21 provided in the center of the fixed spacer. be done.

等の数多の効果を有する。The basic principle of driving the compressor and compressing the working fluid is the same as in the previous embodiment, but fixed scrolls are arranged at two locations, upper and lower, and an upper fixed scroll 22 and a lower fixed scroll 23 are provided. Wraps are provided on both sides of the flat plate of the orbiting scroll 24 in the upper and F directions to form a double-tooth orbiting scroll 24 and fixed to the drive shaft 25 which forms a fluid displacement device at two locations by meshing them together. The crankshaft B26 to which the driven gear 29 to which power is transmitted from the driving gear 28 is fixed is supported by bearings provided on the two fixed scrolls 22 and 23, and the eccentric shaft 44 provided in the center is connected to the orbiting scroll 24 in both figures. It is inserted into a bearing at 21 fixed points provided on the flat plate part of the The two fixed scrolls are each equipped with a top part discharge port 42 and an F part discharge port 43, which are arranged side by side, and a drive shaft 25.
As the two-toothed orbiting scroll 24 rotates, the double-toothed orbiting scroll 24 makes an orbiting motion. 27 is a frame, 31 is a discharge passage, 3
2 is the flat length, 33.34 is the suction pipe, 35 is the discharge pipe, 3
Reference numeral 617 indicates the suction passage connected to the suction pipe.As explained above, according to the present invention, both the driving gear and the driven gear are connected. (By using a drive mechanism consisting of a crankshaft, the orbiting scroll can be rotated and the structure can be simplified.Also, if you want to change the capacity of the compressor, you can change the number of teeth on the gears by using the crankshaft.) The rotation speed can be changed, and the capacity can be easily changed using fixed and orbiting scrolls of the same shape.Furthermore, by changing the number of driven gears from two to three, the load can be easily reduced. Moreover, due to the arrangement of the driven gear, only torque is applied to the drive shaft, and there are many effects such as no load acting in the direction perpendicular to the shaft.

ールの・Ｆ板部でクランク軸を受けることにより、作動
流体圧縮荷重の作用点と支愕点が一致し軸受の信頼性が
向上する等の効果を有する。In the case of a twin-scroll compressor with two fluid displacement devices, in addition to the above effects, no axial thrust force acts on the double-toothed orbiting scroll, resulting in less friction loss and compression. It is possible to increase the capacity of the machine. Furthermore, by receiving the crankshaft at the F plate portion of the double-toothed orbiting scroll, the point of action of the compressive load of the working fluid coincides with the point of support, which improves the reliability of the bearing.
