Accompanying drawing explanation
The above and other features of the present invention, character and advantage become more obvious by passing through below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the sectional view of the oblique tray type compressor of one embodiment of the invention.
Fig. 2 is the partial schematic diagram of the swash plate of one embodiment of the invention.
Embodiment
Below in conjunction with specific embodiments and the drawings, the invention will be further described; set forth more details in the following description so that fully understand the present invention; but the present invention obviously can implement with multiple this alternate manner described that is different from; those skilled in the art when doing similar popularization, deduction without prejudice to when intension of the present invention according to practical situations, therefore should can not limit the scope of the invention with the content of this specific embodiment.
Between the sliding friction parts of versus high motion, when both mutual pressure are large, force of sliding friction is large, easy to wear.Especially as some friction means in compressor, swash plate in such as oblique tray type compressor and between crawler shoe, between the sliding blade of sliding-vane compressor and cylinder body, due to by high pressure, the effect such as centrifugal, lubricant oil is thrown out of, be difficult to rest on sliding friction parts, oil starvation situation makes wearing and tearing aggravate.
Due to when oil starvation, high pressure, versus high motion, can reflect that the frictional behaviour of slider is good and bad, if slider can adapt to such bad working environments, the energy continuous firing long period is not by heavy wear or produce scuffing, then this slider is inevitable also be adapted to common operating mode.The swash plate of compressor is often in above-mentioned bad working environments, and therefore embodiment is for the swash plate of compressor, introduces on the friction means of high speed rotary motion, arranges slip film, action principle and test effect.
As shown in Figure 1, the shell of oblique tray type compressor is assembled by front end housing 2, cylinder body 1 and bonnet 4, forms crankshaft cavity 5, air aspiration cavity 6, exhaust cavity 7 and multiple cylinder-bore 21.During compressor operating, main shaft 9 rotates in crankshaft cavity 5, and drives dress drive plate 11 thereon and the swash plate 10 hinged with drive plate 11 to rotate simultaneously, end face and 9 one-tenth, main shaft one inclination angle of swash plate 10.Multiple piston 18 is contained in each cylinder-bore 21 respectively, arranges a pair crawler shoe 8 between each piston 18 and swash plate 10, piston 18 to-and-fro motion in cylinder-bore 21 in swash plate 10 rotation process.When piston 18 is towards top and bottom motion, respectively by refrigerant gas from air aspiration cavity inhaling air cylinder holes 21, and drain into exhaust cavity 7 from cylinder-bore 21, thus complete the compression to gas.
The rotating speed of swash plate 10 generally reaches more than 800 revs/min, when piston 18 moves bottom cylinder-bore 21, in cylinder-bore 21, gas pressure intensity can reach about 2MPa, inertial force during the pressure that piston 18 end face bears and piston 18 move acts on swash plate 10 through crawler shoe 8 transmission, and the pressure that crawler shoe 8 acts on swash plate 10 can reach about 1200N.
Swash plate 10 generally adopts iron, such as QT500 cast iron or 45 steel, or aluminum alloy is as matrix.Crawler shoe 8 is generally made up of Ferrious material, and as Bearing Steel, GCr15 steel, and through Quench and temper process, hardness is high.Because crawler shoe 8 hardness is high, the matrix 10A of swash plate 10 is more easy to wear.Therefore increase slip film 10B on swash plate matrix 10A surface, to reduce swash plate 10 and the friction ractor of crawler shoe 8, improve lubrication effect.
As shown in Figure 2, slip film 10B composition comprises binding resin 10C and is dispersed in the solid lubricant in binding resin 10C.For the binding resin 10C of slip film 10B, polyimide resin (polyimide) or polyamide-imide resin (Polyamide-Imide) can be selected, the weight percentage of binding resin 10C in slip film 10B is 35-75%, preferred 55-70%; Solid lubricant is one or more in polytetrafluoroethylene (PTFE) 10D, molybdenum disulfide 10E, graphite 10F, and the weight percentage of solid lubricant in slip film 10B is 15-45%, preferred 25-40%; Another containing mineral filler 10G, one or more in optional silicon carbide, silica, silicon nitride, boron nitride, silica and aluminium sesquioxide, weight percentage is 2-20%, preferred 3-8%.
In solid lubricant, at least part of teflon 10D '/molybdenum disulfide 10E ' is for spherical, or at least part of graphite 10F ' is sheet, and namely slip film contains at least one in spherical teflon, spherical molybdenum disulfide and flake graphite.
In slip film 10B, spherical teflon 10D ' average basal particle diameter 1-15 μm, particle diameter accounts for 50% of solid lubricant percent by volume at the spherical teflon 10D ' of this scope.Spherical molybdenum disulfide 10E ' average basal particle diameter 20-200nm, accounts for 5% of solid lubricant percent by volume.Flake graphite 10F ' (though be sheet, essence is particulate matter) average basal particle diameter 50-300nm, thickness 5-30nm, account for 2% of solid lubricant percent by volume.Spherical molybdenum disulfide 10E '/spherical teflon 10D ' in friction process with between transfer membrane engaging friction pair, play micro-ball effect, in addition, in friction process, part spherical molybdenum disulfide 10E ' particle is driven plain, and forms physics friction film, simultaneously, in the polishing scratch that the particles filled ditch plough to friction pair of part spherical molybdenum disulfide 10E ', pit and wearing and tearing produce, indirectly intercept the direct contact of friction pair, thus improve the antiwear and friction reduction property of coating.Sheet nano graphite 10F ' is in friction process, deposit to surface of friction pair, under the effect of frictional force and load, sheet nano graphite 10F ', dissociate between layers, and along dissociating planar slide, form one deck flake transfer membrane at surface of friction pair, the direct contact of indirect obstruct friction pair, thus improve the antiwear and friction reduction property of coating.
In mineral filler 10G, be nano-powder at least partly, Mean particle diameter 10-100nm.Nanometer powder physical efficiency is scattered in the gap of the spherical teflon in embodiment, spherical molybdenum disulfide and flake graphite etc. equably.
In order to verify whether the improvement of solid lubricant of the present invention promotes the effect of slip film, anti-seizing property test and wear test are carried out.
Lock seam test condition is: lock seam test adopts disc type dry wear test machine, swash plate embodiment sample 1-4 and comparative example sample 5-7, body material adopts No. 45 steel, be of a size of Φ 95mm × Φ 55mm × 6mm, wherein each matrix of samples surface forms identical roughness, and then form the binding resin containing same composition and mineral filler respectively on surface, binding resin is weight percentage 60%, mineral filler is weight percentage 5%, and slip film thickness is 0.03mm; The weight percentage of total solid lubricant of embodiment's sample and comparative example sample is 30%.The crawler shoe of Relative friction pair is hemispherical, diameter of phi 15, material adopts GCr15 steel, 3 crawler shoes are distributed on swash plate specimen surface, and by rotating disk, 3 crawler shoes are applied to the pressure of 2000N altogether, swash plate sample with the rotational speed of 800r/min, produces sliding friction pair, process of the test non lubricant oil under the drive of rotating disk.In this condition, mensuration swash plate and crawler shoe reach the time of interlocking pattern.The slip film component of test specimen is as table 1, and table 2 is through the time value testing the bite-resistant recorded.
