Description
Technical field
The invention belongs to Compressor Technology field, relate in particular to a kind of rotary rotor compressor, make the blade-type rotary compressor of translation rotation more specifically to a kind of rotor.
Background technique
As everyone knows, the rotary compressor with leaf structure uses extremely extensive, comprise blade and make the sliding-vane compressor of rotation motion, blade reciprocating rolling piston compressor and the blade swinging rotor type compressor doing oscillating motion etc., traditional blade structure class rotary compressor adopts rotor to make the working method of rotation motion mostly, therefore rotor is larger relative to the movement velocity of end cap and cylinder, can produce larger friction and wear thus, be the significant obstacle that limit compression machine rotating speed improves.For this reason, prior art CN101387294B proposes a kind of translational rotor type compressor, it comprises rotor, cylinder body, blade and end cap, its rotor offers the rotor rollaway nest of flat, cylinder body offers the cylinder body chute of flat, the T-shaped structure of described blade or L shape structure, blade is made up of two orthogonal radial flat bodies and tangential bluff body, wherein radial flat body is fitted in the chute of rotor and is also slidably matched with it, tangential bluff body is then fitted in cylinder body chute and is also slidably matched with it, translation rotation is done at the constraint lower rotor part of blade, prior art US5074769 then proposes another kind of translational rotor type compressor, its rotor offers rotor rollaway nest, blade and bayonet lock is fitted with in rotor rollaway nest, end cap arranges rail groove, bayonet lock is connected with blade and inserts in end cap rail groove, utilize rail groove to retrain bayonet lock and and then the movement locus of constraint blade, final constraint rotor do translation rotation campaign, bayonet lock also impels and keeps the outer end of blade and cylinder holes wall to be seal the state contacting and be sealed and matched simultaneously.The advantage of above-mentioned translational rotor type compressor is the working method that their rotor all adopts translation rotation, therefore rotor is less relative to the movement velocity of cylinder and end cap, rotating speed can be improved compared with traditional blade structure class rotary compressor, therefore volume can be done when discharge capacity is constant by it less, but, above-mentioned translational rotor type compressor still has deficiency: the 1) compressor that proposes of such as CN101387294B, because it must offer the cylinder body chute of flat on cylinder body, cause its processing more difficult, flat cylinder body chute in addition on cylinder body and the tangential bluff body coordinated with it thereof cause again more matching gap, also exacerbate the internal leakage amount of compressor thus, its sealing is poor in other words, 2) compressor that US5074769 proposes, then because the outer end of blade coordinates with cylinder bore wall moving contact that is circular or curvecd surface type, for ensureing sealing, its blade outer end must make curved so as when diverse location and cylinder holes wall configuration adapt, the pattern of position, usual blade outer end needs the curved surface making the combination of many circular arcs, cause the making of blade quite difficult, its end cap rail groove is curvilinear path grooved rail in addition, therefore the processing of rail groove is more difficult too, also vaned outer end can only seal in the mode of linear contact lay with cylinder cylinder holes wall, therefore sealing reliability is poor equally.
Summary of the invention
The invention provides a kind of vane type translational rotor compressor, its main purpose is the manufacture difficulty at the prerequisite decline low compression machine keeping rotor translation rotation working method, and another object of the present invention improves the sealing between blade and cylinder holes wall.
The object of the present invention is achieved like this: vane type translational rotor compressor, comprise rotor, cylinder body, blade, end cap and crank, cylinder body offers cylinder holes, described rotor, blade are all placed in this cylinder holes, rotor offers the rotor rollaway nest of two flat, described blade is fitted in rotor rollaway nest and is also slidably matched with it, two axle sides of rotor and blade move with two end caps being placed in cylinder body diaxon side respectively and coordinate, the cylinder holes of described cylinder body offers the groove that two have planar bottom surface, the bottom surface of two grooves is relatively parallel; Two exterior edge faces of described blade are slidably matched with the bottom surface one_to_one corresponding of described groove respectively, and the outer end of blade has makes with groove floor the working surface coordinated that moves.
The outer end of above-mentioned blade includes Stamping Steel Ribbon, and described Stamping Steel Ribbon coordinates with the bottom surface motion seal of cylinder holes groove.
