Brief description of drawings
Following with reference to accompanying drawing, preferred embodiment of the present utility model is made detailed description so that design of the present utility model and characteristics clearly are described, wherein:
Shown in Figure 1 is the utility model variable-displacement rotary tilting-tray compressor sectional view; And
Fig. 2 A, Fig. 2 B are the swash plate schematic perspective view and the sectional views of compressor shown in Figure 1, wherein show the swash surfaces structure through broken section.
Embodiment
Shown in Figure 1 is the utility model variable-displacement rotary tilting-tray compressor sectional view; And Fig. 2 A, 2B is the schematic perspective view and the sectional view of the swash plate of compressor shown in Figure 1, wherein shows the surface structure of swash plate through broken section.As shown in the figure, variable-displacement rotary tilting-tray compressor of the present utility model comprises front case 1, and cylinder block 2 and rear case 3, one main shafts 4 penetrate in the crank chamber 5 that front case 1 and cylinder block 2 constituted.Be combined with pivoted arm 6 on the main shaft 4, pivoted arm 6 be interference fitted on the main shaft 4 to rotate with the rotation of main shaft 4.Swash plate 7 is set on the main shaft 4 and rotates and can slide along the longitudinal axis of main shaft 4 with main shaft.Pivoted arm 6 connects swash plate 7 by a pin framework 8.Be respectively equipped with crawler shoe 9 on the bi-side of swash plate 7, the piston 10 in the piston hole of cylinder block 2 is connected in swash plate 7 by crawler shoe 9, and it is reciprocating in piston hole that swash plate 7 drives piston 10 with main shaft 4 rotations.In addition, also be provided with control valve 11 at rear case 3.
In the utility model, the substrate of swash plate 7 is adopted aluminum alloy material to forge and is made, and wherein aluminum alloy material can be the silicon-aluminum containing alloy, for example is silumin; Utilizing and forging processing is that aluminum alloy blank is exerted pressure, and makes it produce plastic deformation to have required mechanical property.Can eliminate defectives such as cast condition that aluminum alloy produces is loose by forging in smelting process, to optimize heterogeneous microstructure, to have preserved complete metal streamline again so that the intensity of swash plate can satisfy the service behaviour requirement of compressor simultaneously.
Swash plate workpiece after the forging need advance surface treatment, and therefore swash plate of the present utility model comprises following structure: as Fig. 2 A, shown in the 2B, the outer surface 71 of the utility model swash plate comprises lubricating layer 711.After swash plate 7 being finished forging processing, the swash plate workpiece that machines is immersed in the solvent that contains lubricated composition, contain multiple components in this lubricated solvent to form a lubricating layer 711 at swash plate 7 outer surfaces 71.Subsequently, the swash plate workpiece surface is carried out anodizing, make the swash plate outer surface form oxidation film layer 712, and oxidation film layer has higher hardness to improve the wear resistance of swash plate outer surface greatly, concrete processing method for example can be that the swash plate workpiece is placed main body as anode is the electrolytic solution of sulfuric acid, utilizes electrolysis (can add some additives on request in the electrolytic solution) to make aluminum alloy material surface form the aluminum oxide film rete.Yet, the oxidized aluminum alloy rete is a kind of porous structure, has very high adsorption performance, aggressive medium in the compressor enters the thin layer hole easily and causes and pollute and the swash surfaces friction factor is increased, therefore in the utility model, the aluminium oxide rete has also been carried out sealing to be handled, for example adopt a kind of nanometer anti-friction agent, suction-operated by the aluminium oxide rete is filled into anti-friction agent and forms confined bed 713 in the hole on the film reaching the effect of sealing porous structure, thereby prevents that swash plate outer surface friction factor from increasing.
By forge the swash plate substrate that forms by aluminum alloy material; and lubricating layer, aluminium oxide rete and confined bed are set at its outer surface; can make swash plate of the present utility model have enough intensity on the one hand; have required lubricity, wear resistance, corrosion resistance simultaneously; thereby guarantee that crawler shoe rotatablely moves stably on swash surfaces; thereby improve service behaviour, the Economy of compressor complete machine, and alleviated the weight of complete machine.
