Abstract
The utility model discloses a rotary compressor which comprises a first workpirce and a second workpiece which relatively move, wherein a diamond-like coating, a molybdenum bisulfide coating or a diamond-like and molybdenum bisulfide composite coating is arranged on the surface of the first workpirce; a diamond-like coating, a molybdenum bisulfide coating or a diamond-like and molybdenum bisulfide composite coating is arranged on the surface of the second workpiece; the first workpiece is a piston; and the second workpiece is a slip sheet, a main bearing, a secondary bearing, an intermediate separation board, an eccentric shaft or an air cylinder. Or the first workpiece is the slip sheet and the second workpiece is the air cylinder, the main bearing, the secondary bearing or the intermediate separation board; or the first workpiece is a crankshaft and the second workpiece is the main bearing or the secondary bearing. According to the rotary compressor disclosed by the utility model, due to the adoption of the technical scheme, the wear resistance of the first workpiece and the second workpiece which relatively move can be enhanced, friction coefficients of the first workpice and the second workpirce in the sliding or rolling friction process are reduced; and in addition, cracks or stripping of the coating can be prevented and the service life of the coating is prolonged.
Description
Technical field
The utility model relates to a kind of rotary compressor.
Background technique
Compressor is the important component part in the refrigeration cycle, and refrigeration cycle can not only be used for air conditioner, refrigerator, refrigeration showcase etc., can also be used for heat pump water heater.In these refrigeration cycle, mainly adopt HFC refrigeration agent or other HC class refrigeration agent, CO
2Refrigeration agent, R32 refrigeration agent etc.
Referring to Fig. 1, be existing rotary compressor, taken in motor 2 and compressing mechanism in the closed shell 1, motor 2 comprises stator 4 and rotor 5, rotor 5 is connected with bent axle 6 in the compressing mechanism.Compressing mechanism comprises cylinder 8, place in the cylinder 8 and be enclosed within the piston 11 on the eccentric shaft 63 of bent axle 6 lower ends, and the tip 12a of slide plate 12 contacts with the periphery of piston 11.When piston 11 rotations, piston 11 and slide plate 12 slide relative are seen accompanying drawing 2.
During compressor operating, refrigeration agent is compressed into pressurized gas at compression chamber, because the both sides of slide plate are in low pressure chamber and hyperbaric chamber respectively, slide plate bears the load p that produces from the pressure difference between low pressure and the high pressure.Because slide plate is along with piston is done the high speed to-and-fro motion, so the surface of the tip of the both sides of slide plate and slide plate and piston is easy to generate wearing and tearing.Particularly for some refrigeration agents, like R401A refrigeration agent, CO
2Refrigeration agent etc., slide plate is high at operating pressure, between low pressure chamber and the hyperbaric chamber pressure reduction when big, be more prone to abrasion, working life is also shorter.
A kind of design proposal of on slide plate, carrying out siliceous DLC DLC-Si coating is disclosed among the Japanese documentation JP2007100517.DLC is called for short DLC, and its material is one of amorphous substate structure existence form of carbon, is the amorphous substate structure that graphite composition and diamond composition are arranged mixing of artificial synthesis, has the common performance of graphite and diamond.Because the DLC coating is stable inadequately, to send out combination force not enough with the slide plate matrix, comes off easily, thereby often in the preparation process, mix other element, so Japanese documentation JP2007100517 just mixes in the preparation process Si element arranged.
When the DLC coating is set on slide plate; Can improve the hardness and the wear resistance of slide plate, still, because the hardness of this type coating is very high; Receive when impacting at slide plate; On the one hand cause disbonding easily, cause the breaking and increase abrasion of workpiece of doing relative movement with slide plate on the other hand easily, cause the reliability decrease of this workpiece.
The model utility content
The purpose of the utility model aims to provide that a kind of simple and reasonable, flexible operation, wear resistance are good, long service life, rotary compressor applied widely, to overcome deficiency of the prior art.
A kind of rotary compressor by this purpose design; Comprise first workpiece and second workpiece of doing relative movement; Its structure characteristic is the composite coating that the surface of first workpiece is provided with diamond-like coating, molybdenum disulfide coating or DLC and molybdenum disulfide, and the surface of second workpiece is provided with the composite coating of diamond-like coating, molybdenum disulfide coating or DLC and molybdenum disulfide.
Said first workpiece is a piston, and second workpiece is slide plate, main bearing, supplementary bearing, central diaphragm, eccentric shaft or cylinder.
Said first workpiece is a slide plate, and second workpiece is cylinder, main bearing, supplementary bearing or central diaphragm.
Said first workpiece is a bent axle, and second workpiece is main bearing or supplementary bearing.
After the utility model adopts above-mentioned technological scheme; Can improve first workpiece of doing relative movement and the wear resistance of second workpiece; Reduce first workpiece and second workpiece friction factor in slip or rolling friction process, and can prevent that coating from crackle occurring and peeling off, and prolongs its working life.
The utlity model has that simple and reasonable, flexible operation, wear resistance are good, long service life, advantage of wide range of application.
