Embodiment
See Fig. 1,2,5, compressor of the present invention comprises that cylinder block 3, first end cap 4 and second end cap 5 constitute compressor case, and in the present embodiment, first end cap is that front cover 4, the second end caps are rear end cover 5.Cylinder block 3 is circular, and its radial inner end face is inside ring-type curvilinear plane, and this curvilinear plane surrounds the compressor inner chamber in its paraxial position and tangent connection of the axial internal face of discoidal front cover 4 and rear end cover 5, and the point of contact is 28 (seeing Fig. 4 b).In the present embodiment, this curvilinear plane is the curvilinear plane of annulus outer ring surface shape, and is understandable, and curvilinear plane can also be the curvilinear plane of other shape, for example ellipsoid, revolution paraboloid etc.Suction port 9 and relief opening 10 are arranged on the cylinder block 3, the center of disc rear end cover 5 inboards is provided with cylindrical stub shaft seat 17 and minor axis 2, rotor 8 is installed on the disc front cover 4 prejudicially by rigidly connected live axle 1, rotor center 1 is that e (sees Fig. 4 a) with the throw of eccentric at cylinder block center 2, make rotor 8 approximate tangent, constitute active chamber 11 with the internal surface of cylinder block 3.
" O " body of rotor 8 likeness in form openings at one side, the radial outer end face of rotor 8 is made into the curvilinear plane 22 of the annulus outer ring surface shape similar to cylinder block 3 radial inner end face radians, that sealing is suitable with shape, curvilinear plane 22 paraxial positions and 15 tangent connections of rotor body (being curvilinear plane 22 and tangent connection of both sides axial end of rotor), the point of contact is 29 (seeing Fig. 4 b); On one side the center of rotor body 15 live axle 1 that is rigidly connected wherein on the rotor 8, rotor 8 another side sides are circular cavities 16, the effect of cavity 16 is that to make way for slide plate 6, minor axis seat 17 and minor axis 2 movable therein.
Install 1 group or organize slide plate 6 on the rotor 8 more, corresponding one or more " V " shape opening 24 of opening on the rotor curvilinear plane 22, effect is that the slide plate 6 of stepping down is swung therein, connect vane slot 12 on the rotor body of the proximal ends of each " V " shape opening 24, the opposing side of vane slot 12 is the cylndrical surface, and the axis of cylndrical surface is 13; Connect one " U " v notch v 14 on wherein on one side the rotor body 15 of vane slot 12 proximal ends, effect is swung and flexible with respect to rotor 8 the paraxial part of slide plate 6 therein.The opposing side of " V " shape opening 24 has a plurality of discharge launders 25, so that slide plate when swing got rid of fluid.In addition, will lean on live axle 1 rotor body 15 middle parts on one side to be made into ring areola 21, only make rotor radial peripheral edge portion and cylinder end piece contact seal, can reduce surface friction drag between rotor and end cap.
Arc slide block 7 is set, the cylndrical surface coaxial line 13 of the curvilinear plane of arc slide block 7 and vane slot 12 respectively between the relative cylndrical surface of the both sides of slide plate 6 and vane slot 12.Therefore, slide plate 6 can also be the axis swing with 13 with respect to rotor 8 radial expansions not only.Narrower proximal ends is provided with bearing hole 18 on the slide plate 6, and the minor axis 2 on the rear end cover 5 inserts wherein, and slide plate 6 is rotated around minor axis 2 all the time.
Fig. 3 illustrates one group of slide plate working principle of compressor.Rotor 8 is by live axle 1 rotary driving, and driving slide plate 6 and arc slide block 7 rotates together, slide plate 6 radial end faces are adjacent to cylinder block 3 and slide, and active chamber 11 is separated into the working room, front and back, swept volume of a single chamber changed before and after the rotor rotation made slide plate, realized air-breathing and compression function.A, b, c, d, e, f are respectively the working conditions of 0 °, 90 °, 180 °, 240 °, 305 °, 360 ° of slide plate rotations among Fig. 3.
Because minor axis 2 inserts in the bearing hole 18 of slide plate 6 proximal ends, and slide plate 6 has in vane slot 12 around axis 13 swings and the function flexible with respect to rotor 8, the center of circle that causes the proximal ends of slide plate 6 to depart from rotor 8, in rotor cavity 16 and " U " v notch v 14, be that swing in the axle center with 13, cause slide plate 6 to rotate around minor axis 2 (also being the axle center of cylinder body 3) all the time, and rotor 8 is still around the rotational of live axle 1.The rotor of this structure compressor and slide plate rotate around its center of circle separately, and mutual noninterference does not all produce reciprocal inertia, vibrates very little; Slide plate 6 radial lengths are a fixed length, and its radial outer end face can keep small equidistant slipper seal with cylinder block 3 inwalls, make the wearing and tearing of slide plate and cylinder body very little, improve sealing effect, stable working.
So, though rotor 8 is around live axle 1 rotation, and the slide plate 6 above it is the center of circle (minor axis) 2 rotations around cylinder block, because slide plate 6 radially-outer surfaces have and the consistent curvilinear plane in the cylinder block 3 inwall centers of circle, make slide plate and cylinder keep face contact seal, significantly reduce wearing and tearing and rush down leakage, also can as reciprocating-piston compressor, on slide plate, install seal ring additional, slow-speed of revolution performance will be improved.
Fig. 4 a is that compressor plan view direction camber line of the present invention is created into figure.One section arc section 19 and rotor 8 same axis (axis of live axle 1) among the figure on the cylinder block 3, the tie point of the main circular arc of it and cylinder block circular arc 3 is 20, make arc section 19 and rotor 8 keep small equidistant sealing, formed the sealing configuration of face contact, strengthened active chamber and isolated and sealing effect; Equally, slide plate diametral curve face 23 and the same axis of cylinder block (axis of minor axis 2) among the figure, and form face contact seal structure with inboard wall of cylinder block; Fig. 4 b is that left view direction camber line is created into figure, cylinder block 3 radial inner end curvilinear planes and slide plate 6 radial outer end curvilinear plane together circle centers 31 among the figure.
Fig. 6 is that a kind of proximal ends is the compressor that whole slide plate and rotor embed end cover structure.With front cover 4 inboards make one with the suitable disc concave surface 26 of rotor 8 sides sizes, the rotor body 15 of rotor 8 is embedded wherein rotates.This structure can be cancelled the minor axis seat 17 of rear end cover 5 inboards and the U-shaped breach 14 on the rotor body 15, slide plate 27 proximal ends width are increased, strengthened slide plate intensity, and convenient a plurality of slide plates are hingedly mounted on the minor axis 2 and (for example with the staggered segmentation setting of the bearing hole of a plurality of slide plates, thereby a plurality of slide plates are installed on the same minor axis 2); Equally, rear end cover 5 inner side surfaces are dug the spill annulus 32 that a circle matches with rotor side surface, the rotor side surface projection is embedded wherein slipper seal (or rolling bearing), this structure can be strengthened rotor strength and slow-roll stabilization.
In addition, can also on cylinder block segmental arc 19, slide plate footpath, axial end and rotor axial end face, install seal ring (bar) additional, strengthen sealing effect.
