Abstract
涡旋压缩机的涡旋盘，在动、静涡旋盘上分别有两条各自独立的涡旋线齿。四条涡旋线齿相互啮合形成四个独立的月牙形压缩腔，气体从进气口分成四路进入四个进气腔进行压缩，最后汇总，由同一排气孔排出机外。本发明在相同的涡旋盘外形尺寸和相同的主轴转速下，增大了进气量，增加了涡旋盘中心部分的空间利用率，降低了曲轴的回转半径，减小了动、静涡旋盘相对运动的线速度，使得动涡旋盘受力均匀，减小了整机的振动。
The scroll disk of the scroll compressor has two independent scroll teeth on the movable and static scroll disks. The four vortex teeth mesh with each other to form four independent crescent-shaped compression chambers. The gas is divided into four paths from the air inlet and enters the four air inlet chambers for compression. Finally, it is collected and discharged out of the machine through the same exhaust hole. The present invention increases the intake air volume, increases the space utilization rate of the center part of the scroll disk, reduces the turning radius of the crankshaft, and reduces the dynamic and static vortex under the same external dimension of the scroll disk and the same spindle speed. The linear velocity of the relative motion of the rotating disk makes the force on the moving scroll uniform and reduces the vibration of the whole machine.
Description
Technical field
The present invention relates to fluid variable capacity mechanical device, is a kind of scroll of scroll compressor, is applicable to the less relatively occasion of compression ratio that air displacement is relatively large and gas is required.
Background technique
More common scroll compressor is a single head scroll molded line tooth in the prior art, this scroll compressor is under the less relatively occasion of the processing compression ratio that air displacement is relatively large and gas is required, exist following shortcoming: 1) size of the orbiting and fixed scroll is bigger, and the boundary dimension of complete machine increases; 2) heart portion utilization ratio of scroll is lower, and the suffered axial force of scroll is bigger; 3) turning radius of bent axle increases, and the relative movement linear velocity of sound vortex increases, and the frictional force of dynamic and static scroll wrap increases, and fricative heat increases, and loss in efficiency increases.
Summary of the invention
The scroll that the purpose of this invention is to provide a kind of scroll compressor, keeping under the constant operating mode of scroll boundary dimension and spindle speed, increased air inflow, increased the space availability ratio of scroll core, reduce the turning radius of bent axle, reduced the linear velocity of dynamic and static scroll relative movement.
The present invention is the scroll of scroll compressor, form by moving scroll and fixed scroll, the vortex filament tooth stretches out the card of moving scroll and fixed scroll respectively, and it is vertical with the moving scroll at place respectively with the fixed scroll card, two vortex filament teeth are independently separately arranged respectively on moving scroll and fixed scroll, moving scroll and fixed scroll are installed together, form four intermeshing vortex filament teeth, be defined as four independently crescent shape gas compression chambeies each week, gas is divided into two-way from suction port and enters air aspiration cavity and compress, gather at last, outside same exhaust port discharge machine.The present invention respectively on moving scroll, fixed scroll relative 180 ° position set up two vortex filament teeth.
Usefulness of the present invention is: under identical scroll boundary dimension and identical spindle speed, increased air inflow, increased the space availability ratio of scroll core, reduced the turning radius of bent axle, reduced the linear velocity of dynamic and static scroll relative movement, make moving scroll stressed evenly, reduced the vibration of complete machine.
Description of drawings
Fig. 1 is the structural drawing of the vortex filament tooth of scroll of the present invention, and moving scroll is identical with the structure of the vortex filament tooth of fixed scroll, and Fig. 2 is the vortex filament tooth mesh schematic representation of moving scroll and fixed scroll.
Embodiment
As shown in Figure 1, the vortex filament tooth stretches out the card of moving scroll and fixed scroll respectively, and vertical with the fixed scroll card with the moving scroll at place respectively, and two vortex filament teeth are independently separately arranged respectively on moving scroll and fixed scroll.As shown in Figure 2, when compressor operating, four vortex filament teeth are meshing with each other, and each week forms four independently crescent shape compression chambers, and gas is divided into two-way from suction port and enters air aspiration cavity and compress, and gathers at last, outside same exhaust port discharge machine.As shown in Figure 1, two scroll molded line teeth are set up in relative 180 ° position on moving scroll and fixed scroll, with respect to single scroll molded line tooth, the Base radius of involute increases, the generation angle of involute reduces, and air-inlet cavity increases to 2, and the volume-variation in single chamber increases, compression speed to gas is accelerated, and the pressure reduction of adjacent compression chamber increases.
Compare with the scroll compressor of in the past single head vortex filament tooth, major advantage of the present invention is: 1) air inflow increases, and under identical scroll boundary dimension and identical scroll wrap wall thickness, air inflow is original 1.6～2 times; 2) the crank up radius reduces, and under identical air inflow and boundary dimension, crank throw is original 0.5～0.7 times; 3) rotating speed is low, and under identical air inflow and boundary dimension, rotating speed is original 0.6～0.8 times; 4) the relative movement linear velocity of sound vortex filament tooth is little, and under identical air inflow and boundary dimension, linear velocity is original 0.4～0.6 times.
Claims (2)
1, the scroll of scroll compressor, form by moving scroll and fixed scroll, the vortex filament tooth stretches out the card of moving scroll and fixed scroll respectively, and it is vertical with the moving scroll at place respectively with the fixed scroll card, the invention is characterized in two vortex filament teeth are independently separately arranged respectively on moving scroll and fixed scroll, moving scroll and fixed scroll are installed together, form four intermeshing vortex filament teeth, be defined as four independently crescent shape gas compression chambeies each week, gas is divided into two-way from suction port and enters air aspiration cavity and compress, gather at last, outside same exhaust port discharge machine.
2, the scroll of scroll compressor according to claim 1 is characterized in that respectively two vortex filament teeth are set up in relative 180 ° position on moving scroll, fixed scroll.
