Abstract
The present invention discloses a vortex disk of a vortex type refrigeration compressor, which relates to a vortex disk device of a vortex type refrigeration compressor, which is designed for vortex-shaped line refrigeration air conditioners by using a new positioning method. The vortex disk of a vortex type refrigeration compressor is composed of a bottom disk part and a vortex-shaped line, wherein the bottom disk part is provided with a bottom disk and a lug boss; the vortex-shaped line is composed of a circular arc and an involute. The present invention is characterized in that the plane center of the bottom disk of the vortex disk part is not coincident with the circular center of the vortex-shaped line, the center of the basic circle of the vortex-shaped line deviates from the geometrical center of the bottom disk of the vortex disk, and the deviation distance is smaller than the pitch of the vortex-shaped line.
Description
What vortex disk of vortex-type refrigerating compressor of the present invention related to is a kind of scroll molded line refrigerating and air conditioning vortex disk of vortex-type refrigerating compressor device that adopts new localization method design that has.
The molded lines basic circle center of circle of existing vortex disk of vortex-type refrigerating compressor all overlaps with the center, bottom plane of scroll, the problem that this location exists is: 1. moving scroll can't self be made once balance, 2. the external dimension of scroll increase, consumptive material increases, 3. need to strengthen the hamming piece, make wasted work increase in the work, efficient reduces, and 4. the dynamic balancing of compressor is relatively poor.
The objective of the invention is to exist deficiency that a kind of vortex disk of vortex-type refrigerating compressor is provided at present vortex disk of vortex-type refrigerating compressor, has the scroll molded line that adopts new localization method design, the planar central on the chassis of scroll does not overlap with the scroll molded line basic circle center of circle, the chassis geometrical center that departs from scroll, adopt the dynamic balance performance of compressor of this scroll better, the work wasted work reduces, and efficient improves, the external dimension of scroll reduce, and consumptive material reduces.
Vortex disk of vortex-type refrigerating compressor is to adopt following scheme to realize: the vortex disk of vortex-type refrigerating compressor structure is made of chassis portion, scroll molded line, chassis portion has chassis, boss, scroll molded line is combined by circular arc, involute, the chassis planar central that it is characterized in that the scroll part does not overlap with the scroll molded line basic circle center of circle, and the chassis geometrical center of scroll is departed from the scroll molded line basic circle center of circle.
The deviation distance of chassis geometrical center of scroll is departed from less than the pitch of scroll molded line in the basic circle center of circle of scroll molded line.
The vortex disk of vortex-type refrigerating compressor molded lines carries out new positioning design, the basic circle that relates to refrigerating and air conditioning scroll compressor molded lines, location, the center of circle, the scroll molded lines of this positional parameter design is suitable for the household air-conditioner compressor centralized air-conditioning, automobile, train, steamer, the air-conditioning on various vehicles such as tank naval vessel and various freezing, all vortex disk of vortex-type refrigerating compressor such as cold storage refrigerator freezer, the refrigeration compressor dynamic balance performance of using scroll of the present invention is better, moving scroll can self be made once balance, can reduce equilibrium block, the work wasted work reduces, efficient improves, the external dimension of scroll reduce, and consumptive material reduces.
The invention will be further described below with reference to accompanying drawing.
Fig. 1 is the vortex disk of vortex-type refrigerating compressor left view.
Fig. 2 is the vortex disk of vortex-type refrigerating compressor plan view.
With reference to accompanying drawing vortex disk of vortex-type refrigerating compressor structure by chassis portion, scroll molded line constitutes, chassis portion is made of chassis 1, boss 3, scroll molded line is combined by circular arc 5,6, involute 8, circular arc 5 is to be the how much identical circular arcs of circle radius in the center of circle and chassis with O ', circular arc 6 is circular arcs tangent with involute 8, and involute 8 is that the O point is the involute medial and lateral shape line in the center of circle.Chassis one side is provided with scroll molded line 2, opposite side is provided with boss 3, and bearing hole 4 is arranged in the boss, and chassis 1 planar central of scroll does not overlap with scroll molded line basic circle 7 center of circle O, the chassis 1 geometrical center O of scroll is departed from scroll molded line basic circle 7 centers of circle, and deviation distance is less than scroll molded line pitch h.
With reference to accompanying drawing 2 vortex disk of vortex-type refrigerating compressor molded lines positioning design as shown in the figure:
A. the bottom plane center O ', cross at O ' and make x ', y ' rectangular coordinate system.
B. do x " x " make x " x " be parallel to x '-x ' and make the distance equal ± ε.
C. do y " y " make y " y " be parallel to y '-y ' and make the distance equal ± δ.
D.x " x " and y " y " intersect, and obtain another rectangular coordinate system, and initial point is the O point.
E. be the center of circle with the O point, with x " o rotates an angle ± α, obtain like this one new: x-x, the new rectangular coordinate system of y-y.The initial point O point of system of coordinates is exactly the center of circle of basic circle, and the intersection point of oy and basic circle is exactly the basic circle starting point.
