Description
Technical field
The present invention relates to a kind of scroll compressor, especially a kind of simple in structure, the scroll compressor that transmission efficiency is high, specifically a kind of scroll compressor of gasket-pin structure.
Background technique
As everyone knows, in scroll compressor (electronic or powered by conventional energy), in order to make Moving plate, in the drive of bent axle, make mutually plane rocking, must restriction Moving plate can not rotation, at present conventional mode has steel ball reorder two kinds of the structure of Zhu Quan and ring pin structures, Chinese patent 2006100405145,2008100236786 etc. is all reorder structures of Zhu Quan of the steel ball that adopts, this structure need install stop ring additional to Moving plate end face and front end surface in order to guarantee wear resistance, and because the volume of steel ball is larger, therefore make the volume of scroll compressor strengthen, weight strengthens; In addition because the Ding Zhuquan of stationary balls is thin-walled parts, processing and heat treatment deformation are large, make the positioning precision of steel ball lowly, and during the work of compressor, steel ball noise is large.And volume, weight and running noise are used the significant of scroll compressor for automobile.Chinese patent 2007100254972 discloses a kind of typical ring pin structure, although this structure has overcome the steel ball volume and weight large problem that pearl coil structures exists of reordering, but its ring body used is long-pending and wall thickness is too little, processing difficulties, during assembling, in encircling, need two pins of plug-in mounting, and gap is very little between two pins, be subject to the impact of setting angle, during installation, very a performance is in place several pins simultaneously, therefore Chinese patent 200910213085.0 discloses a kind of lightweight, process the compressor of gasket-pin structure easy for installation, it adopts at least three Kong Bingyu protecgulums of processing on a packing ring to fix, the pin that installation equates with hole number on Moving plate is realized the plane rocking of Moving plate, although but people find comparatively ideal of this structure in practice, but due to many technical parameter materials of packing ring, surface hardness, the diameter of pin, highly, packing ring position structure, matching gaps etc. all directly have influence on the life-span of compression, noise, the how each relevant parameter of choose reasonable, reach best fit effect, it is the key that this class formation is realized industrialization, there is no at present relevant parameter can be for selecting, directly have influence on the raising of the performance of this type of gasket-pin structure scroll compressor.
Summary of the invention
The object of the invention is because lacking rational structural parameter, can not give full play to its due function for the scroll compressor of existing gasket-pin structure, directly affect the problem of industrialization process, by lot of experiment validation, it is the scroll compressor of the gasket-pin structure that industrialization provides that a kind of noise is little, the life-span is long, safe and reliable.
Technological scheme of the present invention is:
A kind of scroll compressor of gasket-pin structure, comprise 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 the other end is connected with protecgulum 6, after Moving plate 3 and quiet dish 2 interfix, be arranged in casing 1, eccentric bushing 4 is arranged on Moving plate 3 and with bent axle 5 and is connected by clutch shaft bearing 10, one end that bent axle 5 is provided with eccentric bushing 4 is bearing on the second bearing 11, it is characterized in that, on Moving plate 3 end face relative with protecgulum 6, pin 13 is installed, it is 3-5.5 millimeter that thickness is installed on protecgulum 6 end face relative with Moving plate 3, hardness is HRC40-50, material is the packing ring 14 of 40Cr or 20CrMo, packing ring 14 is provided with the circular hole 12 equating with described pin 13 quantity, the height H of described pin 13 equals the 80%-95% of described packing ring 14 thickness, described packing ring 14 is positioned at by locating stud 19 on the end face of protecgulum 6 relative Moving plates 3, on locating stud 19 and packing ring 14, between corresponding positioning hole 14a, is Spielpassung, and the matching gap between locating stud 19 and positioning hole 14a is 0.045-0.127.
The supporting quantity of circular hole 12 of offering on described pin 13 and described packing ring 14 is 4 covers.
Described bent axle 5 is connected with motor by belt pulley.
The diameter of the circular hole 12 of offering on described packing ring 14 equals the described diameter of pin 13 and the turning radius sum of Moving plate 3 and adds 0.01-0.15mm.
Described locating stud 19 is 4 with the quantity of positioning hole 14a.
The diameter of described pin 13 is 3.8-4.2 millimeter.
Beneficial effect of the present invention:
The present invention has obtained desirable thickness of slab size, pin diameters, height etc. by great many of experiments directly affect the parameter in compressor noise and life-span, especially on packing ring, the Optimum clearance of positioning pin hole 14a and fixing pin 19 is 0.045-0.127, gap is young pathbreaker too, packing ring 14 installs to difficulty on location 19, gap too during large compressor operation the gap between packing ring 14 and locating stud 19 can when compressor start, can produce noise.
The present invention is by experimental results demonstrate, packing ring 14 preferably adopts 40Cr or 20CrMo to manufacture, hardness should be controlled to HRC40-50 simultaneously, washer face hardness is too low can just there is abrasion deformation in the life time that does not reach GB/T27942 regulation, hardness too during large compressor operating 14, packing ring there will be the phenomenon of cracking.
In addition, the present invention found through experiments the diameter of pin and highly also directly has influence on the raising of compressor combination property, has therefore proposed optimum diameter and has exposed the optimum range of the height H on Moving plate surface.
All parameters of the present invention all draw through experimental verification repeatedly, it has filled up the parameter blank of related domain, all parameters are all to propose first, it not the common practise of related domain, overcome the technology prejudice of related domain simultaneously, change the general knowledge that it is believed that simple selection gets final product, creatively drawn best parameter matching by viewpoint and the thinking of systems engineering.
The present invention and the traditional steel ball pearl coil structures of reordering is compared with ring pin structure, and number of components is few, and (determine Zhu Quan for few two, two stop rings and 16 steel balls, increase a circle and four pins; Few four rings compared with ring pin structure, four pins), there is lightweight, easy for installation advantage, to reorder compared with pearl coil structures with the steel ball of same specification, the weight of every compressor can alleviate more than 120 grams, has reduced the cost of raw material; Installation time determine pearl coil structures with steel ball compared with average every can shorten more than 1 minute.
In addition, due to the axial cumulative error that has reduced two stop rings and a steel ball at compressor, add the quality of fit and the parameter optimization that have improved sound dish, more than the efficiency of compressor improves 10 %, the overall noise of compressor is average less more than 5 decibels than existing gasket-pin structure.
