[1] first embodiment

Fig. 1 represents first embodiment.Fig. 2 is the A-A sectional view of Fig. 1.The anti-bead face that has first fixed scroll 1 of whirlpool shape bead at runner plate is fastened on the casing 100.Be provided with the revolution scroll 10 that has whirlpool shape bead at runner plate overlappingly with first fixed scroll 1, be provided with second fixed scroll 2 that has whirlpool shape bead at runner plate overlappingly with revolution scroll 10, and be fastened on first fixed scroll 1.Constitute operating member by first fixed scroll 1, revolution scroll 10 and second fixed scroll 2.The first fixed scroll bead 1a and be located at the revolution vortex bead 10a of revolution on the scroll 10 and make up and constitute one group of first operating chamber 21.Being located at revolution vortex bead 10b and the second fixed scroll bead 2a of revolution on the scroll 10 makes up and constitutes one group of second operating chamber 22.

Two positions on casing 100 are provided with the outer ring of swivel bearing 101.Running shaft 102 is entrenched in the inner ring of swivel bearing 101.The stator 105 of motor is fastened on the casing 100, and the rotor 106 of motor is fastened on the running shaft 102.And, the balace weight 47 that is used to guarantee whole centrifugal force balance is installed on running shaft 102.On running shaft 102, be provided with bearing housing at two ends from the position of rotating center off-centre, this bearing housing is provided with the outer ring of floating bearing 103.Turning axle 104 is entrenched in the inner ring of floating bearing 103.Turning axle 104 is connecting the first fixed scroll openings 1c.Center in revolution scroll 10 is provided with the hole.This hole is chimeric with revolution drive portion 104a with not counterrotating state.Turning axle one end 104b is connecting the second fixed scroll openings 2c, and extends to the outside.Prevent being fastened on the turning axle one end 104b from flap 109.As shown in Figure 2, prevent from shipping and reselling on another market 110 anti-being embedded with from three positions of inner surface side of flap 109.Anti-rotation bearing (guide mechanism) 111 is arranged on the surface side of second fixed scroll 2 as anti-rotation guider.Anti-rotation unit by anti-from flap 109, anti-from ship and resell on another market 110 and anti-rotation bearing (guide mechanism) 111 constitute.Anti-from shipping and reselling on another market 110 to make up with the tangent state of anti-rotation bearing inner race 112.Be made as d1 with anti-from 110 the external diameter of shipping and reselling on another market, the internal diameter of anti-rotation bearing inner race 112 is made as D1, the turning radius of the turning axle 104 when this fluid machinery is turned round is made as ε, when the bearing internal void is made as δ, is set between d1, D1, ε, δ and has following relation:

2 ε-δ≤D1-d1≤2 ε+δ (formula 1)

When so setting the value of D1-d1, anti-ly 110 keep roughly the state tangent, and prevent the rotation of turning axle 104 reliably with anti-rotation bearing inner race 112 from shipping and reselling on another market.And turning axle one end 104b can be not crooked to the inside because of brute force yet.So, can not produce noise, mechanical loss diminishes.Even the centrifugal action of revolution scroll 10 is in revolution drive portion 104a, if the bearing internal void of anti-rotation bearing (guide mechanism) 111 becomes 0, then turning axle one end 104b can be not crooked more yet.Can prevent the contact of vortex bead thus.So, also can realize comparing in the past the more rotation of high speed even convolute-hydrodynamic mechanics has bigger revolution scroll.

Discharge cap 113 is fastened on the outer surface of second fixed scroll 2 with the state of sealing discharge chamber 114.Wrapping anti-in the discharge cap 113 from flap 109 and anti-rotation bearing (guide mechanism) 111.On discharge cap 113, be provided with exhaust port 108.Peripheral part at second fixed scroll 2 is provided with suction port 107.

Then, the action to this convolute-hydrodynamic mechanics describes.When the energising of the spiral of stator 105, rotor 106 is rotated, running shaft 102 be rotated and turning axle 104 as described below preventing rotation ground is by eccentric drive.Revolution drive portion 104a revolution driving rotational scroll 10 as the part of turning axle 104.First operating chamber 21 that is made of the first fixed scroll bead 1a and revolution vortex bead 10a and second operating chamber 22 that is made of the second fixed scroll bead 2a and revolution vortex bead 10b are from the inside all side shiftings of outer circumferential side, thereby the inner fluid of volume reducing compresses.Runner plate central part in revolution scroll 10 is provided with revolution runner plate connecting port 10c.So operating chamber 21 and operating chamber 22 are connected at central part.Its result, fluid sucks from suction port 107, compresses via suction chamber 130, and to operating chamber 22 sides interflow, flows into to discharging chamber 114 by the second fixed scroll openings 2c, and discharge to the outside from exhaust port 108.

Since anti-from ship and resell on another market 110 outside diameter d 1 and anti-rotation bearing inner race 112 inside diameter D 1 and turning radius ε between have the relation of formula 1, thereby anti-from ship and resell on another market 110 always and anti-rotation bearing inner race 112 between carry out rotation motion when keeping to a certain degree contact force.Owing to anti-110 be located at anti-from flap 109 two more than the position, thereby anti-ly carry out rotation motion, but be not rotated from flap 109 from shipping and reselling on another market.Owing to prevent being fastened on turning axle one end 104b, thereby turning axle 104 carries out rotation motion with being prevented from rotation from flap 109.And,, thereby prevent that rotation ground from carrying out rotation motion because revolution scroll 10 is chimeric with revolution drive portion 104a with not counterrotating state.

, because revolution scroll 10 has weight, thereby when revolution scroll 10 is carried out rotation motion, producing centrifugal force with the rectangular direction of axle.All centrifugal force are by balace weight 47 cancellations.But above-mentioned centrifugal force becomes makes the load of revolution scroll in the radial direction displacement on axle.This load becomes the load that makes revolution drive portion 104a bending.Revolution drive portion 104a with floating bearing 103 as fulcrum, along the direction bending of resultant load.Its result, the simultaneous displacement that revolution scroll 10 also tilts to the direction of resultant load.Therefore, revolution vortex bead 10a and 10b are near the first fixed scroll bead 1a and the second fixed scroll bead 2a.Between the bead too near the time, in order to suppress leakage rate to greatest extent, the gap that originally is set between little bead becomes 0, and begins to slide.So produce slippage loss in bead.And, in convolute-hydrodynamic mechanics, produce vibration noise.And then, the abrasion of bead progress or between bead, produce burn-back.The Performance And Reliability that is convolute-hydrodynamic mechanics is simultaneously impaired.

But, according to the present invention because anti-110 tangent with anti-rotation bearing inner race 112 from shipping and reselling on another market, thereby turning axle one end 104b can be not corresponding by anti-from ship and resell on another market 110 and more than the turning radius of anti-rotation bearing inner race 112 decisions displacement.So even revolution scroll 10 is carried out high speed rotating, centrifugal force increases and makes the load of revolution drive portion 104a bending become big, also can prevent to turn round the bending of drive portion 104a.So, can not contact between the bead.So, also can realize comparing in the past the more rotation of high speed even convolute-hydrodynamic mechanics of the present invention has bigger revolution scroll.

Fig. 3 is the partial sectional view of expression first embodiment's variation.As shown in Figure 3, substituted anti-rotation bearing (guide mechanism) 111 as anti-rotation guider with anti-rotation slide member (guide mechanism) 115.Anti-rotation unit by anti-from flap 109, anti-from ship and resell on another market 110 and anti-rotation slide member (guide mechanism) 115 constitute.Anti-rotation slide member (guide mechanism) 115 is made by self lubricity parts such as resins.110 be directed carrying out rotation motion with the internal surface inscribe of anti-rotation slide member (guide mechanism) 115 time owing to anti-from shipping and reselling on another market, thereby can prevent the rotation of turning axle 104 and revolution scroll 10, simultaneously turning axle one end 104b can't be corresponding by anti-from shipping and reselling on another market 110 and the turning radius above ground displacement of anti-rotation slide member (guide mechanism) 115 decisions.

So and since anti-from ship and resell on another market 110 and anti-rotation slide member (guide mechanism) 115 tangent, thereby can prevent to turn round the rotation of scroll reliably.And, even the centrifugal action of revolution scroll 10 in revolution drive portion 104a, turning axle one end 104b also not can anti-from ship and resell on another market 110 and anti-rotation slide member (guide mechanism) 115 tangent after bending.Thus, can prevent contact between the bead.So,, also can compare in the past more at a high speed and high-precisionly carried out rotation motion even convolute-hydrodynamic mechanics of the present invention has bigger revolution scroll.
