Embodiment

[1] first embodiment

Fig. 1 represents the first embodiment.Fig. 2 is the A-A sectional view of Fig. 1.The anti-bead face at runner plate with the first fixed scroll 1 of whirlpool shape bead is fastened on casing 100.Be provided with overlappingly the revolution scroll 10 at runner plate with whirlpool shape bead with the first fixed scroll 1, be provided with overlappingly second fixed scroll 2 at runner plate with whirlpool shape bead with revolution scroll 10, and be fastened on the first fixed scroll 1.By the first fixed scroll 1, revolution scroll 10 and the second fixed scroll 2, form operating member.The first fixed scroll bead 1a and be located at the revolution vortex bead 10a of revolution in scroll 10 and combine and form one group of first operating chamber 21.Being located at the revolution vortex bead 10b of revolution in scroll 10 and the second fixed scroll bead 2a combines and forms 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 casing 100, and the rotor 106 of motor is fastened on running shaft 102.And, on running shaft 102, be provided with for guaranteeing the balace weight 47 of whole centrifugal force balance.On running shaft 102, at the two ends of the position from rotating center bias, be provided with bearing housing, on this bearing housing, be 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.At revolution scroll 10 center, be provided with 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 outside.Prevent being fastened on the 104b of turning axle one end from flap 109.As shown in Figure 2, anti-being embedded with from three positions of inner surface side of flap 109, prevent from shipping and reselling on another market 110.Anti-rotation bearing (guide mechanism) 111 is arranged on the surface side of the second fixed scroll 2 as anti-rotation guider.Anti-rotation unit by prevent from flap 109, anti-from ship and resell on another market 110 and anti-rotation bearing (guide mechanism) 111 form.Anti-from shipping and reselling on another market 110 to combine with the tangent state of anti-rotation bearing inner race 112.By anti-, from 110 the external diameter of shipping and reselling on another market, be made as d1, the internal diameter of anti-rotation bearing inner race 112 is made as to D1, the turning radius of the turning axle 104 when this fluid machinery is turned round is made as ε, when bearing internal void is made as to δ, is set as having following relation between d1, D1, ε, δ:

2 ε-δ≤D1-d1≤2 ε+δ (formula 1)

While so setting the value of D1-d1, anti-ly from shipping and reselling on another market, 110 maintain roughly tangent with anti-rotation bearing inner race 112 state, and prevent reliably the rotation of turning axle 104.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 if 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, turning axle one end 104b can be not crooked more yet.Can prevent the contact of vortex bead thus.So, even if convolute-hydrodynamic mechanics has larger revolution scroll, also can realize the rotation of comparing in the past more at a high speed.

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

Then, the action of this convolute-hydrodynamic mechanics is described.To spiral when energising of stator 105, rotor 106 is rotated, running shaft 102 be rotated and turning axle 104 as described below prevent rotation by eccentric drive.Revolution drive portion 104a revolution as the part of turning axle 104 drives revolution scroll 10.The first operating chamber 21 consisting of the first fixed scroll bead 1a and revolution vortex bead 10a and the second operating chamber 22 of consisting 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, and to operating chamber 22 side interflow, flow into, and discharge to outside from exhaust port 108 by the second fixed scroll openings 2c to discharge chamber 114 via suction chamber 130.

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

, 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 is cancelled by balace weight 47.But above-mentioned centrifugal force becomes makes to turn round scroll in the load of radial direction displacement on axle.This load becomes the load that makes to turn round drive portion 104a bending.Revolution drive portion 104a is usingd floating bearing 103 as fulcrum, crooked along the direction 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 approach the first fixed scroll bead 1a and the second fixed scroll bead 2a.While too approaching between bead, in order to suppress to greatest extent leakage rate, the gap being originally set as between little bead becomes 0, and starts to slide.So in bead, produce slippage loss.And, in convolute-hydrodynamic mechanics, produce vibration noise.And then, the abrasion of bead progress or produce burn-back between bead.The Performance And Reliability that is convolute-hydrodynamic mechanics is simultaneously impaired.

But, according to the present invention, due to 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 shipping and reselling on another market 110 and the turning radius above ground displacement that determines of anti-rotation bearing inner race 112.So even if revolution scroll 10 is carried out High Rotation Speed, centrifugal force increases and the load that makes to turn round drive portion 104a bending becomes large, also can prevent from turning round the bending of drive portion 104a.So, between bead, can not contact.So, even if convolute-hydrodynamic mechanics of the present invention has larger revolution scroll, also can realize the rotation of comparing in the past more at a high speed.

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

So, due to anti-from ship and resell on another market 110 and anti-rotation slide member (guide mechanism) 115 tangent, thereby can prevent from reliably turning round the rotation of scroll.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 the contact between bead.So, even if convolute-hydrodynamic mechanics of the present invention has larger revolution scroll, also can compare in the past more at a high speed and high-precisionly carry out rotation motion.

2 ε-δ≤D2-d2≤2 ε+δ (formula 2)

While so setting the value of D1-d1, turning axle one end 104b maintains roughly tangent with equalizer bearing inner ring 52 state.And turning axle one end 104b can be not crooked to the inside because of Strong power yet.So, can not produce noise, mechanical loss diminishes.Even if the centrifugal action of revolution scroll 10 is in revolution drive portion 104a, if the bearing internal void of equalizer bearing (guide mechanism) 51 becomes 0, turning axle one end 104b can be not crooked more yet.Can prevent the contact of vortex bead thus.So, even if convolute-hydrodynamic mechanics has larger revolution scroll, also can realize the rotation of comparing in the past more at a high speed.
