Description
The utility model relates to a kind of air condition compressor, specifically, relates to the plunger oblique tray type compressor in a kind of automotive air conditioning system.
Usually, the plunger oblique tray type compressor of automotive air conditioning system (below abbreviate oblique tray type compressor as) is to drive its main shaft by vehicular engine or its external driver device magnetic clutch by compressor, and will rotatablely moving by swash plate and crawler shoe simultaneously, the linear reciprocating motion that converts plunger to works.Therefore, the contacted surface of swash plate and crawler shoe must have good wear resistance, fatigue resistance and seizure resistance, carries out linear motion stably to guarantee crawler shoe.But the described contact surface of existing swash plate does not reach above-mentioned requirements, improves to cause user cost to such an extent as to influence the service behaviour of working life of swash plate and compressor.
Therefore, the purpose of this utility model provides a kind of plunger oblique tray type compressor of car air-conditioner, and the contact slidingsurface of its swash plate has good wear resistance, fatigue resistance and seizure resistance, thereby can improve the durable reliability of compressor complete machine.
For achieving the above object, the plunger oblique tray type compressor of car air-conditioner of the present utility model, it comprises: protecgulum, cylinder block, bonnet and control valve, rotary main shaft, drive plate and swash plate crawler shoe mechanism; Described protecgulum is connected with the front end of described cylinder block by sealing, and described bonnet and control valve are connected with the back-end sealing of described cylinder block by valve board assembly; Described protecgulum and cylinder block are in conjunction with forming the crank box inner chamber; Described rotary main shaft passes described crank box inner chamber and can be rotated to support in the bearing hole of protecgulum and cylinder block; Described rotary main shaft and described drive plate are fastenedly connected; Described swash plate is located in and also is connected one on the described main shaft by linkage and with described drive plate; Described swash plate and main shaft keep tilting; Described crawler shoe is arranged between swash plate and the plunger skirt section; Be characterized in: contacted two the slidingsurface spreadings of described swash plate and crawler shoe have sprayed metal coating, and described sprayed metal coating has the surface of porous.
Described sprayed metal coating comprises a kind of solid lubricant; Described oiling agent is one of molybdenum disulfide, graphite, fluorocarbon resin, tin and lead.
Adopt technique scheme of the present utility model; be used for because the swash plate of compressor and the sprayed metal coating that contacted two slidingsurfaces of crawler shoe have porous surface; this not only helps soaking into lubricating oil; and compare with original contact surface; its wear resistance, fatigue resistance and seizure resistance have been significantly improved; thereby guarantee that crawler shoe drives plunger and carries out linear motion stably, and then improve the service behaviour and the durable reliability of compressor complete machine.
In order further to understand the purpose of this utility model, characteristics and advantage, will be specifically described a preferred embodiment of the present utility model in conjunction with the drawings below.
Fig. 1 is the longitudinal section of the variable displacement plunger oblique tray type compressor of the utility model one preferred embodiment;
Fig. 2 is the schematic perspective view through the swash plate of metal spraying of preferred embodiment shown in Figure 1.
Fig. 1 illustrates the variable displacement plunger oblique tray type compressor of the utility model one preferred embodiment.As shown in the figure, the variable displacement plunger oblique tray type compressor of car air-conditioner of the present utility model, it comprises: the swash plate crawler shoe mechanism that protecgulum 1, cylinder block 2, bonnet and control valve (not shown), rotary main shaft 7, drive plate 8 and swash plate 10 and crawler shoe 11 are formed.Protecgulum 1 is connected with the front end of cylinder block 2 by sealing 3, and bonnet and control valve are connected (not shown) by valve board assembly with the back-end sealing of described cylinder block.Protecgulum 1 and cylinder block 2 are in conjunction with forming crank box inner chamber 6.Rotary main shaft 7 passes crank box inner chamber 6 and is bearing in by bearing in the bearing hole of protecgulum 1 and cylinder block 2.Rotary main shaft 7 is fastenedly connected with drive plate 8.Swash plate 10 is located on the main shaft 7 and the one that is connected with drive plate 8 by linkage 9.Swash plate 10 keeps certain angle of inclination with main shaft.Crawler shoe 11 is arranged between the skirt section of swash plate 10 and plunger 12.Be characterized in: swash plate 10 has sprayed metal coating 4,4 ', the surface that sprayed metal coating 4,4 ' has porous with crawler shoe 11 contacted two slidingsurface spreadings.Sprayed metal coating 4,4 ' comprises a kind of solid lubricant; Described oiling agent can be one of molybdenum disulfide, graphite, fluorocarbon resin, tin and lead.
In the course of the work, by magnetic clutch (not shown) or other clutch mechanism rotary main shaft 7 is connected with vehicular engine and is rotated motion.Swash plate will be done oscillating motion around main shaft when main shaft 7 rotation, make plunger 12 institute on cylinder block 2 make linear reciprocating motion among a plurality of cylinder-bore 2a of formation at interval by crawler shoe 11.Temperature rising heat load in the traffic tool increases, by the pressure in the effect raising crankcase intracavity 6 of the control valve 4 in the compressor bonnet 3 angle of waving of swash plate 10 is increased, increase with the linear reciprocating motion stroke that reaches plunger 12, thereby corresponding the obtaining of discharge capacity of compressor increased.In the present embodiment, earlier the swash plate slidingsurface with former beginning and end spraying carries out pretreatment, to increase this surperficial roughness, then two of the parent of the swash plate of making by steel or cast iron materials 10 with crawler shoe contact surface metalizing coating.The metal that is applicable to this metallic coating has aluminium based metal material and copper-based metallic material.As shown in Figure 2, two of swash plate 10 surperficial 10a
1And 10a
2Through metal spraying.Metal spraying is that thread or powdery metal material are heated to softening or melted state, and further atomizes, quickens, and deposits to swash plate 10a then
1And 10a
2The surface on.Contain solid lubricant in this metallic coating, therefore make swash plate slidingsurface 10a just like molybdenum disulfide, graphite, fluorocarbon resin, tin and lead etc.
1And 10a
2Friction factor less.Increased surface roughness owing to carry out pretreatment earlier before the spraying, strengthened the adhesiveness of swash plate slidingsurface and metallic coating, thereby can prevent the phenomenon of peeling off of sprayed metal coating.
Though more than be that example specifies the utility model with the car air-conditioner variable displacement plunger oblique tray type compressor of the utility model one preferred embodiment, but it should be understood that this embodiment embodiment be equally applicable to the plunger oblique tray type compressor of fixed displacement.
The utility model is to be coated with the metal level that contains kollag at the slidingsurface that coils with crawler shoe, and it is bright Aobvious technique effect is: 1. metal coating has porous organization, and this is conducive to the infiltration of lubricating oil and reduces tiltedly The coefficient of friction of panel surface to improve the anti-wear performance of swash surfaces, has improved the seizure resistance of slidingsurface Energy. 2. sprayed metal coating comprises kollag, and the coefficient of friction of swash plate is obviously reduced, thereby further Improve the anti-wear performance of swash surfaces. 3. the front swash surfaces of metal spraying is the preliminary treatment by cleaning and sandblast, Improved the bond strength of sprayed coating metal and swash plate matrix surface to guarantee the wearability of swash plate matrix surface Can, anti-fatigue performance and bite-resistant performance, thereby reach plunger and can carry out for a long time linear reciprocal movement, To improve the functional reliability of plunger oblique disc type compressor.
