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, make plane rocking in order to make Moving plate mutually in the drive of bent axle, must the restriction Moving plate can not rotation, mode at present commonly used has steel ball reorder two kinds of the structure of Zhu Quan and ring pin structures, Chinese patent 2006100405145,2008100236786 etc. all is reorder structures of Zhu Quan of the steel ball that adopts, this structure is in order to guarantee that wear resistance needs Moving plate end face and front end surface are installed additional stop ring, and because the volume of steel ball is bigger, therefore make the volume of scroll compressor strengthen, weight strengthens; Because the Ding Zhuquan of stationary balls is a thin-walled parts, processing and heat treatment deformation are big in addition, and be feasible low to the Location accuracy of steel ball, and the steel ball noise is big during the work of compressor.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, though this structure has overcome the steel ball volume and weight big problem that the pearl coil structures exists of reordering, but its used ring body is long-pending and wall thickness is too little, processing difficulties, need two pins of plug-in mounting owing in encircling during assembling, and the gap is very little between two pins, be subjected to the influence of setting angle, very a performance is in place several Zhu Quan of deciding simultaneously during installation, therefore being badly in need of that exploitation is a kind of can weight reduction, processing easily, and position structure easy for installation again.
Summary of the invention
The objective of the invention is the problem that volume is big or installation is inconvenient, design the scroll compressor of gasket-pin structure a kind of simple in structure, easy for installation at existing scroll compressor Moving plate swing mechanism existence.
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 an exhaust end, its the other end links to each other with protecgulum 6, be installed in the casing 1 after Moving plate 3 and quiet dish 2 interfix, eccentric bushing 4 is installed on the Moving plate 3 and with bent axle 5 by clutch shaft bearing 10 and links to each other, bent axle 5 is equipped with an end bearing of eccentric bushing 4 on second bearing 11, it is characterized in that on Moving plate 3 and protecgulum 6 opposing end faces, pin 13 being installed, on protecgulum 6 and Moving plate 3 opposing end faces packing ring 14 is installed, packing ring 14 is provided with the circular hole 12 that equates with described pin 13 quantity.
The quantity of described pin 13 is at least 3, and pin 13 inserts circular hole 12, forms pair relationhip, and the quantity of the pairing that forms is at least 3 pairs.
Described bent axle 5 links to each other with motor rotor or links to each other with motor by belt pulley.
The diameter of the circular hole of offering on the described packing ring 14 12 equals the turning radius sum of the diameter and the Moving plate 3 of described pin 13.
The diameter of the circular hole of offering on the described packing ring 14 12 preferably equals the diameter of described pin 13 and the turning radius sum of Moving plate 3 is added 0.01-0.15mm.
Beneficial effect of the present invention:
The present invention and the steel ball pearl coil structures of reordering is compared with ring pin structure, and part number is few, and (decide Zhu Quan for few two, two stop rings and 16 steel balls increase a circle and four pins; Compare few four rings with ring pin structure, four pins), have advantage in light weight, easy for installation, to compare with the steel ball of the same specification pearl coil structures of reordering, the weight of every compressor can alleviate more than 100 grams, has reduced the cost of raw material; Installation time and steel ball are decided the pearl coil structures and are compared average every and can shorten 0.5 minute; Compare with ring pin structure and can shorten more than 1 minute.
In addition, in the axial cumulative error that has reduced two stop rings and a steel ball of compressor, improved the quality of fit of sound dish, the efficient of compressor improves more than 2%; Eliminated steel ball and decided the collision noise in Zhu Quan hole, the overall noise of compressor is average littler more than 2 decibels than deciding pearl circle steel ball structure.
