Abstract
The invention provides an axial double-floating structure of a scroll compressor. The scroll compressor adopts a static-scroll axial floating structure or a movable-scroll axial floating structure, wherein sealing grooves are simultaneously formed at tooth tips of a movable scroll and a static scroll; sealing rings are put into the sealing grooves; the tooth tips and tooth bottoms of the movable scroll are respectively in clearance fit with tooth bottoms and the tooth tips of the static scroll; and clearances are larger than the elongation amount of teeth of the scrolls, which is caused due to thermal expansion, and smaller than fit clearances between the tooth tips and the tooth bottoms of the static and the movable scrolls of a compressor which does not float and adopts tooth tip sealing ring structures of the movable and the static scrolls. Compared with the prior art, the axial double-floating structure has the advantages that leakage at the tooth tips and the tooth bottoms of the movable and the static scrolls can be effectively reduced, the tooth height fitting accuracy of the movable and the static scrolls can be further lowered, and the processing economy of the scrolls is improved.
Description
Technical field
The present invention relates to compressor, relate in particular to the axially two floating structures of scroll compressor.
Background technique
The axial float structure majority of existing scroll compressor is quiet whirlpool dish axial float, movable orbiting scroll axial float (as shown in Figure 1) and non-floating, and adopts movable orbiting scroll and quiet whirlpool dish tooth top ring structure (as shown in Figure 2).The dynamic and static whirlpool dish of corresponding quiet whirlpool dish axial float and movable orbiting scroll axial float structure; Direct contact matching at the bottom of general quiet whirlpool dish tooth top and the movable orbiting scroll tooth; Because vortex heart portion is different with external temperature, usually to revising at the bottom of dynamic and static whirlpool dish tooth depth or the tooth, the tooth depth quality of fit of the sound whirlpool dish that matches simultaneously is high; Generally the method through apolegamy or raising machining accuracy realizes that the processing Economy is bad.Wearing and tearing at the bottom of special operation condition might cause sound whirlpool dish tooth top and tooth in addition, this wearing and tearing are irreversible, make after the wearing and tearing to leak in the compressor to increase, and cause the reduction of compressor efficiency.And corresponding non-floating; Adopt movable orbiting scroll and quiet whirlpool dish tooth top ring structure; For the interlock stuck phenomenon that prevents sound whirlpool dish takes place; Two places are Spielpassung at the bottom of dynamic and static whirlpool dish tooth top and the tooth;
gap is nearly hundred microns, and this just causes vortex to leak increase, can cause the reduction of compressor efficiency.
Summary of the invention
The object of the invention exactly for a kind of gap that can effectively reduce at the bottom of tooth top and tooth are coiled in the sound whirlpool is provided, can reduce sound whirlpool dish tooth depth quality of fit again, improves the axially two floating structures of scroll compressor of the processing Economy of whirlpool dish.
In order to achieve the above object; The present invention has adopted following technological scheme: the axially two floating structures of a kind of scroll compressor; It is characterized in that this scroll compressor adopts quiet whirlpool dish axial float structure or movable orbiting scroll axial float structure, at movable orbiting scroll and quiet whirlpool dish tooth top seal groove is set simultaneously; Put into seal ring, and two places at the bottom of sound whirlpool dish tooth top and the tooth are joined and be Spielpassung.
The gap of described Spielpassung is greater than the elongation of whirlpool dish tooth thermal expansion, less than the non-matching gap of floating, adopting at the bottom of tooth top and tooth are coiled in the movable orbiting scroll and the sound whirlpool of quiet whirlpool dish tooth top ring structure.
The elongation of described whirlpool dish tooth thermal expansion is 10～30 microns.
The matching gap that coil at the bottom of tooth top and the tooth in described non-sound whirlpool unsteady, that adopt movable orbiting scroll and quiet whirlpool dish tooth top ring structure is 40～150 microns.
Compared with prior art, the present invention is combination or the movable orbiting scroll axial float structure of quiet whirlpool dish axial float structure and movable orbiting scroll, quiet whirlpool dish tooth top ring structure and the combination that the tooth top ring structure is coiled in movable orbiting scroll, quiet whirlpool.Make or quiet whirlpool dish axial float through this structure, this structure both can effectively reduce the gap at the bottom of sound whirlpool dish tooth top and the tooth, can reduce sound whirlpool dish tooth depth quality of fit again, improved the processing Economy of whirlpool dish.
