Abstract
A scroll compressor relates to the improvement of meshing component for the air conditioning compressor, in particular to the surface structural improvement of orbiting scroll and fixed scroll for scroll compressor. The utility model has characteristics that horniness anode oxidation treatment is applied to the orbiting scroll and fixed scroll cast and grilled of aluminum alloy; a scroll wall surface is gilded with a layer of anodic oxide film with a thickness of 15-30Mum, then coated with a layer of lubricating film such as MOS2 film with a thickness of 5-10Mum. The total film thickness error of the scroll wall can be within plus or minus 5Mum, so the friction coefficient of the improved orbiting scroll and fixed scroll is reduced, the anti- scoring ability is greatly improved, the exhaust temperature of the compressor is reduced, the energy efficiency ratio is improved and the service life of the compressor is prolonged. The scroll compressor is especially suitable for automobile air conditioning.
Description
Technical field
A kind of scroll compressor is involved in the improvement of mesh component in the air condition compressor, and specifically moving scroll is improved with the surface structure of deciding scroll in the scroll compressor.
Background technique
The moving scroll and the precision of deciding material, hardness and vortex wall that scroll is important critical component, particularly this a pair of meshing engagement structure can directly have influence on the quality and the working life of scroll compressor in scroll compressor.Existing moving scroll much is to reach necessarily required precision with fine finishing behind the aluminum alloy material casting to form with deciding scroll, owing to the friction of this a pair of engagement pair after the compressor long-term work makes the vortex wall have damage, and owing to the engagement of moving scroll and decide between scroll is a kind of linear engagement, so will cause gas leak phenomenon and have influence on the efficient of compressor as long as wall surface roughness and profile tolerance are overproof, again because the not high friction factor that can increase this a pair of engagement pair of the precision of its vortex wall, and the axle input power of compressor is increased, delivery temperature increases, increase energy consumption greatly, shortened the working life of compressor.
Summary of the invention
The purpose of this utility model is to improve the friction factor that the surface structure of deciding scroll or moving scroll in the scroll compressor reduces its engagement pair, improves the precision of engagement, improves the Energy Efficiency Ratio of compressor, prolongs the working life of compressor.
The utility model adopts following technological scheme to implement: a kind of scroll compressor by clutch assembly 1, crank assemblby 2, end cap assembly 3, moving scroll 4, decide scroll 5, housing 6, compression chamber 7 and form, decide scroll 5 and moving scroll 4 is to use aluminum alloy material, after reaching necessarily required precision and form by fine finishing behind the typing specification casting, when decide scroll 5 or moving scroll 4 vortex wall and carrying out the hard anodizing processing or after the anodizing, outside anode oxide film 8, be formed with one deck lubricating film 9 in its contact.
This in actual applications lubricating film 9 can be MOS
2Film or poly tetrafluoroethylene; The thickness deltat of anode oxide film 8 is 15～30 μ m, and lubricating film 9 thickness δ are 5～10 μ m, on the vortex wall this two membranes total thickness error be controlled at ± 5 μ m within.The thickness of its film is thick, and then surface structure is loose, easy to wear coming off, but thickness has approached very much and has not had effect, through our development repeatedly, the thickness deltat of anode oxide film is good with 15～30 μ m, the thickness δ of lubricating film is good with 5～10 μ m, and on the vortex wall this two membranes total thickness error be controlled at ± 5 μ um within for best.
Moving scroll of making of aluminum alloy material 4 or the vortex wall of deciding scroll 5 have adopted the technical solution of the utility model, its film hardness can reach HV400, lubricating film plays and reduces moving scroll and decide the engaging friction coefficient that vortex is cross-examined, input power can reduce 100W after measured, delivery temperature can descend 4～5 ℃, and its Energy Efficiency Ratio COP value can improve 5%, this shows to have saved energy consumption greatly, improve the performance and the anti-engagement ability of air compressor, prolonged working life.
The utility model can be widely used in compressor, is specially adapted to automobile air conditioner compressor.
Because of moving scroll is relative with the spin friction of deciding scroll, in order to save cost, so can reach effective function as long as one of them scroll forms rete, thus below to form rete with moving scroll be accompanying drawing embodiment, the detailed description the technical solution of the utility model.
Description of drawings 1. scroll compressor structure diagrams
Among the figure: 1. clutch assembly 2. crank assemblbies 3 end cap assemblies 4. moving scroll 5. are decided scroll 6.
Among the figure: 8 anode oxidation membranes, 9. lubricant film layer Fig. 4. decide scroll plan view Fig. 5. decide the B-B sectional view of scroll
See shown in the accompanying drawing 1. that scroll compressor is by clutch assembly 1, crank assemblby 2, end cap assembly 3, moving scroll 4 and decides scroll 5, housing 6, compression chamber 7 and assemble.Moving scroll 4 is linear tight engagement with deciding contacting of scroll 5, when compressor operating, decide scroll relatively and do translation by the moving scroll of bent axle drive, its vortex wall be constantly with decide scroll engagement and friction, so require moving scroll and the material of deciding scroll that rational difference of hardness is arranged, and lower friction factor arranged.So in the scroll compressor decide scroll and moving scroll with aluminum alloy material by typing specification casting after fine finishing, after reaching necessarily required precision, carry out hard anodizing and outside anode oxide film 8, be formed with one deck lubricating film 9 when handling or after the anodizing deciding scroll 5 or moving scroll 4 vortex wall in its contact.Present embodiment is that moving scroll 4 is carried out earlier being coated with last layer MoS again after anodizing has formed one deck anode oxide film 8
2 Film 9.
See accompanying drawing 2 and shown in Figure 3, with the wall of deciding the moving scroll 4 that scroll 5 contacts on carry out anodizing to have formed one deck anode oxide film 8 its thickness deltat be 20 μ m, be coated with last layer MoS then equably
2 Film 9 is baking-curing again, so that MoS
2Film is cemented on the oxide side of wall well, the MoS after the curing
2The thickness δ of film is 8 μ m, and the total thickness of this two membranes is 28 μ m, and the total profile tolerance error of thickness is less than 4 μ m.Decide scroll 5 and see accompanying drawing 4 and accompanying drawing 5, just need not carry out anodizing and form lubricating film.
The mounted scroll compressor of present embodiment is used for air conditioner for automobile, and having measured its Energy Efficiency Ratio COP value is 2.35%, and delivery temperature is 95 ℃, has prolonged the working life of compressor.
