The shape of blade 60,61 as shown in Figure 9, it is coupling, and to touch curvature portion R4 corresponding with the periphery pars convoluta of running shaft 20, so that contact with running shaft 20 outer circumferential face maintenance faces. Blade 60,61 by blade body part B, isolating plate contact surface part R3, be coupling and touch curvature portion R4, cylinder contact surface part F5 and elastic bearing mechanism mounting portion F2 forms.Blade body part B has certain thickness and becomes quadrangle; Isolating plate contact surface part R3 is the side of blade body part B, promptly with the curved surface of isolating plate 30 contact and have identical curvature; Being coupling and touching curvature portion R4 is surface of contact and the formation and the corresponding recessed curvature of running shaft 20 peripheral curve that contacts with running shaft 20, so that contact with running shaft 20 outer circumferential face maintenance faces; Cylinder contact surface part R5 touches the relative convex surface of curvature portion R4 with being coupling, and has corresponding curvature with the inwall of cylinder assembly 10 inner space V; Elastic bearing mechanism mounting portion F2 is the side relative with isolating plate contact surface part R3 and elastic bearing mechanism 2 is housed.
Figure 10 is the distortion example of the contact surface of blade 60,61, touch curvature portion R4 with the contacted blade surface of contact of running shaft 20 outer circumferential faces by being coupling and planar section F4 forms, be coupling and touch curvature portion R4 and have certain length and corresponding with the peripheral curve of running shaft 20, make it to contact with running shaft 20 outer circumferential face maintenance faces, planar section R4 then lays respectively to be coupling and touches the both sides of curvature portion R4.
Below the technique effect of compressor blade of the present invention is illustrated.
Running shaft is during by compressor driving mechanism M rotary driving, isolating plate 30 rotates with running shaft 20, and constantly cylinder assembly 10 inner space V (i.e. the 1st space 13 and the 2nd space 14) are converted to respectively by blade 60,61 and to suck regional 13a, 14a and constricted zone 13b, 14b, to compressing by the gas that sucks runner 11 suctions, outwards discharge through discharging runner 12 again, its detailed process as after.
As shown in figure 11, at first, the end of the convex surface part r1 of isolating plate 30 is in the position a1 of blade 60 in the 1st space 13, and the end of the concave curved surface r2 of isolating plate 30 is in the position a1 ' of blade 61 in the 2nd space 14, promptly the 1st space 13 and the 2nd space 14 finish pressurized gas discharging, convert the state that gas sucks to; At this moment, the isolating plate contact surface part R3 of blade 60,61 is consistent with the convex curved surface r1 end and the concave curved surface r2 end of isolating plate 30 respectively, becomes internally the space outside state of exhaust to greatest extent.
As shown in figure 12, then, rely on the rotation of running shaft 20, the convex curved surface r1 end of isolating plate 30 arrives the position a2 of blade 61 through the suction runner 11 in the 1st space 13, simultaneously, the end of concave curved surface r2 is through the 2nd space 14 difference pressurized gass and suction gas.In this process, the isolating plate contact surface part R3 of blade 60,61 respectively with the part convex curved surface r1 of isolating plate 30, be connected curved face part r3 and contact with part concave curved surface r2, and shift to cylinder assembly inner space V respectively with sinusoidal wave curve form.At this moment, being coupling of blade 60,61 touched curvature portion R4 and carried out face with the outer circumferential face of running shaft 20 and contact, and cylinder contact surface part R5 then contacts with the internal face of inner space V, and makes axial straight line in this state and move.
As shown in figure 11, running shaft 20 is rotated further, and the convex curved surface r1 end of isolating plate 30 is in blade 60 positions, and concave curved surface r2 end is in blade 61 positions, and the 1st space 13 and the 2nd space 14 difference releasing compressed gas and end suck the state of gas.In this process, the isolating plate contact surface part R3 of blade 60,61 respectively with the part convex curved surface r1 of isolating plate 30, be connected curved face part r3 and part concave curved surface r2 contacts, and move to the outside of inner space straight line by the outer circumferential face of sinusoidal wave form along running shaft 20.At this moment, being coupling of blade 60,61 touched curvature portion R4 and carried out face with the outer circumferential face of running shaft 20 and contact, and simultaneously, cylinder contact surface part R5 carries out face with the inwall of inner space V and contacts, and straight line moves under this state.
Suck the process of gas and compression, exhausting air so, repeatedly.
In said process, insert the blade 60,61 in the cylinder assembly 10 blade slits 15, it is coupling and touches curvature portion R4 straight line moves carrying out under the face state of contact doing up and down with running shaft 20 outer circumferential faces, and the 1st space 13 of the inner space V of cylinder assembly 10 and the 2nd space 14 be separated into suck regional 13a, 14a and constricted zone 13b, 14b.Because curve that the isolating plate contact surface part R3 of blade 60,61 and a contact surface part R4 intersect and the contact that intersects with isolating plate are also inconsistent with the center line end points of the length direction of sharf contact surface part R4, so still can make the slit to occur between above-mentioned contact and end points and cause, but the present invention can reduce to the slit minimum by the gas leakage of high-pressure section to low-pressure section.
As Figure 13, shown in 14, the inside curve a of isolating plate 30, the curvature and the internal diameter L1 of the curve that to be running shaft 20 intersect with isolating plate 30, and there are difference in curvature and the external diameter L2 of isolating plate 30 outside curve b, the blade 60 that contacts with the waveform pars convoluta along inside curve a and outside curve b, 61 not only have certain thickness, and its isolating plate contact surface part R3 also has certain curvature, therefore, it is also inconsistent with sharf contact surface part R4 length direction center line end points P2 with the contact P1 that isolating plate 30 intersects that being coupling of blade touched the curve that curvature portion R4 and isolating plate contact surface R3 intersect, generation slit A between contact P1 and the end points P2; But,, reduce to minimum to the gas leakage of low-pressure section thereby make by high-pressure section so this slit A can reduce to minimum because sharf contact surface part R4 is that face contacts with the outer circumferential face of running shaft 20.
According to above-mentioned principle, cylinder contact surface part R5 also can prevent gas leakage.
