Description
Technical field
The present invention relates to a kind of scroll compressor, especially a kind of simple in construction, the scroll compressor that transmission efficiency is high, the specifically scroll compressor of a kind of gasket-pin structure.
Background technology
It is known that, in scroll compressor (electronic or powered by conventional energy), in order to make Moving plate make plane rocking mutually in the drive of bent axle, what must limit Moving plate can not rotation, at present conventional mode has steel ball to reorder the structure of Zhu Quan and ring pin structure two kinds, Chinese patents 2006100405145,2008100236786 etc. are all that the steel ball adopted is reordered the structure of Zhu Quan, this structure is in order to ensure that Moving plate end face and front-end surface need to be installed additional locating snap ring by wearability, and owing to the volume of steel ball is bigger, hence in so that the volume of scroll compressor strengthens, weight strengthens；Ding Zhuquan additionally, due to stationary balls is thin-walled parts, and processing and heat treatment deformation are big so that the positioning precision of steel ball is low, and during the work of compressor, steel ball noise is big.And significant for automobile scroll compressor of volume, weight and running noise.nullChinese patent 2007100254972 discloses a kind of typical ring pin structure，Although this structure overcomes steel ball and reorders the big problem of volume and weight that pearl coil structures exists，But its ring body used is long-pending and wall thickness is too little，Processing difficulties，Owing to ring needing plug-in mounting two pin during assembling，And gap is only small between two pins，It is subject to the impact of setting angle，Very several pins are mounted simultaneously to position by a performance during installation，Therefore Chinese patent 200910213085.0 discloses a kind of lightweight，Process the compressor of gasket-pin structure easy for installation，It adopts and processes at least three hole on a packing ring and fix with protecgulum，Moving plate is installed the pin equal with hole number and realizes the plane rocking of Moving plate，Although but people find that this structure is ideal in practice，But the many technical parameter materials due to packing ring、Case hardness、The diameter of pin、Highly、Packing ring location structure、Fit clearances etc. all directly influence the life-span of compression、Noise，How rationally to select each relevant parameter，Reach best fit effect，It it is this class formation key of realizing industrialization，There is no relevant parameter at present alternative，Directly influence the raising of the performance of this type of gasket-pin structure scroll compressor.
Summary of the invention
It is an object of the invention to the scroll compressor for existing gasket-pin structure and can not give full play to its due function because lacking rational structural parameters, the problem directly affecting industrialization process, by lot of experiment validation, provide for industrialization that a kind of noise is little, the scroll compressor of life-span length, safe and reliable gasket-pin structure.
The technical scheme is that
nullA kind of scroll compressor of gasket-pin structure，Including casing 1、Quiet dish 2、Moving plate 3、Eccentric bushing 4、Bent axle 5 and protecgulum 6，One end of casing 1 is exhaust end，Its other end is connected with protecgulum 6，It is arranged in casing 1 after Moving plate 3 and quiet dish 2 interfix，Eccentric bushing 4 is arranged on Moving plate 3 by clutch shaft bearing 10 and is connected with bent axle 5，Bent axle 5 is provided with one end of eccentric bushing 4 and is bearing on the second bearing 11，It is characterized in that, on the end face that Moving plate 3 is relative with protecgulum 6, pin 13 is installed，Being provided with thickness on the end face that protecgulum 6 is relative with Moving plate 3 is 3-5.5 millimeter、Hardness is HRC40-50、Material is the packing ring 14 of 40Cr or 20CrMo，Packing ring 14 is provided with the circular hole 12 equal with described pin 13 quantity，The height H of described pin 13 is equal to the 80%-95% of described packing ring 14 thickness；Described packing ring 14 is positioned on the end face of the relative Moving plate 3 of protecgulum 6 by alignment pin 19, is matched in clearance between hole, the location 14a that alignment pin 19 is corresponding with on packing ring 14, and the fit clearance between alignment pin 19 and location hole 14a is 0.045-0.127.
The supporting quantity of the circular hole 12 offered on described pin 13 and described packing ring 14 is 4 sets.
Described bent axle 5 is connected with electromotor by belt pulley.
The diameter of the circular hole 12 offered on described packing ring 14 adds 0.01-0.15mm equal to the described diameter of pin 13 and the radius of gyration sum of Moving plate 3.
Described alignment pin 19 and the quantity positioning hole 14a are 4.
The diameter of described pin 13 is 3.8-4.2 millimeter.
Beneficial effects of the present invention:
The present invention obtains desirable thickness of slab size, the diameter of pin, height etc. by great many of experiments and directly affects the parameter in compressor noise and life-span, especially on packing ring, the Optimum clearance of dowel hole 14a and steady pin 19 is 0.045-0.127, gap is too little will, then packing ring 14 installs to difficulty on location 19, and during the too big compressor operation of gap, the gap between packing ring 14 and alignment pin 19 can produce noise when compressor start.
The present invention is by experimental results demonstrate, packing ring 14 manufactures preferably with 40Cr or 20CrMo, simultaneously should by Hardness Control at HRC40-50, washer face hardness is too low, can being not reaching in the GB/T27942 life time specified to occur as soon as abrasion deformation, and during hardness too big compressor operating, packing ring 14 then there will be the phenomenon of cracking.
It addition, the present invention is found through experiments the diameter of pin and highly also directly influences the raising of compressor combination property, it is therefore proposed that optimum diameter and expose the optimum range of height H on Moving plate surface.
All parameters of the present invention all draw through experimental verification repeatedly, the parameter that it has filled up this area is blank, all parameters are all propose first, it not the known general knowledge of this area, overcome the technology prejudice of this area simultaneously, change and it is believed that the general knowledge simply selected, creatively drawn the parameter coupling of the best by the viewpoint of system engineering and thinking.
The present invention reorders compared with pearl coil structures and ring pin structure with traditional steel ball, number of components few (determine Zhu Quan for few two, two locating snap rings and 16 steel balls, increase by one and enclose and four pins；Few four rings, four pins compared with ring pin structure), have lightweight, advantage easy for installation, to reorder with the steel ball of same specification compared with pearl coil structures, the weight of every compressor can alleviate more than 120 grams, reduces the cost of raw material；Set-up time determine pearl coil structures with steel ball compared with on average every can shorten more than 1 minute.
In addition, due to the cumulative error having axially reduced two locating snap rings and a steel ball at compressor, plus the quality of fit and the parameter optimization that improve sound dish, the efficiency of compressor improves more than 10%, and the overall noise of compressor is on average less more than 5 decibels than existing gasket-pin structure.
