摘要： PROBLEM TO BE SOLVED: To extend the life of an auxiliary crank mechanism by reducing the weight of an orbiting scroll and suppressing a variation in the deformation of a boss plate.
SOLUTION: Cooling fins 13 are not disposed on the rear surface of the plate body 8A of the orbiting scroll 8 in contact surface low-density areas L1 at the positions corresponding to the areas between three auxiliary crank mounting recessed parts 9B. A large number of cooling fins 13 are disposed in contact area high-density areas H1 at the positions corresponding to the axis O2 of the orbiting scroll 8 and three auxiliary crank mounting recessed parts 9B and at the position where the axis O2 is connected to each auxiliary crank mounting recessed part 9B, and front end parts 13A are brought into contact with the surface of the boss plate 9. Consequently, since the cooling fin 13 can be provided only to the portions of the orbiting scroll 8 where a strength is required, only the portions which tend to be deformed by a large load can be supported and the deformation of the boss plate 9 can be uniformed.

摘要： PROBLEM TO BE SOLVED: To suppress centrifugal whirling and vibration of a turning scroll at a high pressure stage during turning and improve the durability and service life as a device.
SOLUTION: An eccentric shaft 22 inserted to inside of a cylindrical rotating body 18 is formed so that the mass M of the eccentric shaft 22 has a relationship of M≥m with respect to the mass m of the turning scroll 24B at the high pressure stage. The turning scroll 24B at the high pressure stage is set to have a relationship (La≤0.3×Lb) indicating that a distance La from the shaft end of the eccentric shaft 22 to a tip of a lap part 26B is 0.3 time or less a distance Lb between turning bearings 23A, 23B in the axial direction of the eccentric shaft 22. Thus, this can suppress centrifugal whirling and vibration of the turning scroll 24B at the high pressure stage in the radial direction due to the action of centrifugal force and achieve deformation amount δ at the tip of the lap part 26B within a range of allowable deformation amount.

摘要： PROBLEM TO BE SOLVED: To promote reduction of diameter, miniaturization, and reduction of weight of an intermediate part of a turning shaft by supporting axial direction both sides of the turning shaft by using turning bearings.
SOLUTION: The turning bearings 35A, 35B rotatably supporting the turning bearing 25 are provided in eccentric bushing 18A, 18B of the turning shaft 16. At a time of operation of a compressor, turning scrolls 11A, 11B connected to both end sides of the turning shaft 25 are turned in relation to fixed scrolls 5A, 5B by driving the turning shaft 16. At that time, load in a thrust direction acting on the turning shaft 25 from the turning scrolls 11A, 11B is supported at an outside of the intermediate shaft part 26 by the turning bearings 35A, 35B. Consequently, since load in a thrust direction does not act on the intermediate shaft part 26, outer diameter dimension thereof can be reduced and the turning shaft 16 and the turning bearings 20A, 20B or the like can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To reduce a centrifugal force of an orbiting scroll which acts on an auxiliary crank mechanism.
SOLUTION: In a scroll type fluid machine, a crank pin 27B eccentric from a main shaft part 27A is formed in a drive shaft 27 and a main balance weight 35 is provided in a base end side of a crank pin 27B. A main shaft part 27A of the drive shaft 27 is rotatably supported by a main bearing 33, and the crank pin 27B is attached to an orbiting bearing 31 provided at a back surface side of the orbiting scroll 7. Further, an internal gap δb of the main bearing 33 is set to a value larger than a value obtained by subtracting the double value of an eccentric amount difference Δε between an eccentric amount ε' of an auxiliary crankshaft 26 and an eccentric amount ε of the drive shaft 27 from an internal gap δa of the orbiting bearing 31. Consequently, the internal gap δb of the main bearing 33 does not become zero even if a compressor 1 comes to a steady state.

摘要： PROBLEM TO BE SOLVED: To prevent transmission of compression heat generated on a scroll side to an orbiting bearing and application of a moment caused by orbiting motion to a main bearing etc.
SOLUTION: A crank boss part 9 having a bearing storage hole 9A is provided in an eccentric position on a tip side of a drive shaft 7, and an eccentric shaft 10 extended toward the bearing storage hole 9A of the crank boss part 9 is provided in an orbiting scroll 3. The main bearing 11 supporting the crank boss part 9 and the orbiting bearing 12 supporting the eccentric shaft 10 on the bearing storage hole 9A are arranged on the same plane F-F. Therefore, the main bearing 11 and the orbiting bearing 12 can be separated from the orbiting scroll 3, so as to prevent transmission of compression heat to each bearing 11, 12 side. Since a load generated during orbiting of the orbiting scroll 3 can be received by the main bearing 11, a moment applied to the main bearing 11 etc. can be eliminated virtually.
