Abstract
The utility model relates to a volumetric vortex fluid compressor with radial compensating mechanism, relating to the fluid machinery technical field. The volumetric vortex fluid compressor with radial compensating mechanism comprises an articulation balance block connected with a bearing, and a main shaft installed in the articulation balance block; the clearance between the main shaft and the articulation balance block is provided with at least one elastic member. The utility model is used for compressing to the fluid; compare with prior art, the volumetric vortex fluid compressor with radial compensating mechanism can solve the problem that the engagement clearance between a moving vortex disc and a still vortex disc is oversize during low speed operation; simultaneously, the volumetric vortex fluid compressor with radial compensating mechanism can effectively prevent operating members from being damaged during compressing higher density media.
Description
Technical field
The utility model relates to the fluid machinery technical field, especially a kind of displacement vortex fluid compressor with radial compensation mechanism.
Background technique
The scroll fluid compression set is realized the convection cell compression by the relative gear motion of dynamic and static scroll.The moving scroll of this device is to be driven by joint balance piece, bearing by main shaft, because the restriction of manufacturing, assembly precision, moving scroll is difficult to realize omnidistance good engagement with fixed scroll, in order to address this problem, existing scroll fluid compression set, be the installation form that utilizes Spielpassung between its main shaft and the joint balance piece, the centrifugal force that utilizes moving scroll to produce when relying on running compensates the gap that above-mentioned installation precision deficiency causes, to guarantee between the two engagement well.When being used in the big occasion of the fluctuations of speed such as car air-conditioner when this device, when the rotating speed of moving scroll is lower than rating value, can be too small between its orbiting and fixed scroll by the engaging force of centrifugal force decision, thereby produce the radial clearance of dynamic and static scroll vortex face engagement, leakage rate by radial clearance is increased, cause adverse consequencess such as the decrease in efficiency of scroll fluid compression set and machine temperature rise.
Summary of the invention
The utility model provides a kind of displacement vortex fluid compressor with radial compensation mechanism, the excessive problem in back lash of moving scroll and fixed scroll when it can solve low-speed running.
For achieving the above object, the scheme that the utility model adopts is: it comprises the joint balance piece that is connected with bearing, and is installed in the main shaft in the joint balance piece, and the gap location of described main shaft and described joint balance piece is provided with at least one elastic component.
Above-mentioned elastic component can be the capable spring of vortex, can be wavy spring, also can be spring sheet.Its elastic component can be contained in the seat groove of described crank pin, also can be contained in the seat groove of described joint balance piece.
Owing to adopted such scheme the utility model compared with prior art to have following beneficial effect:
The problem of the back lash of moving scroll and fixed scroll when 1, solving low-speed running.Owing in the gap of crank pin and joint balance piece elastic component is housed, moving scroll is when low speed rotation is worked, and it is not enough and cause the back lash and become big to the centripetal force of moving scroll that the elastic force of elastic component can effectively compensate fixed scroll, produces leakage.
2, the damage that parts cause when compression higher density medium that can effectively prevent to turn round.Have the low fluids of compressibility such as liquid state in active chamber, during as media such as oil, water, moving scroll can overcome the elastic force of elastic component and make a concession to the center, makes fluid pass through to leak decompression, thus the damage of the parts of avoiding turning round.
3, can avoid producing the problem of leaking the machine temperature rise that is caused because of low-speed running.
Description of drawings
Fig. 1 is the utility model embodiment's a structural drawing.
Fig. 2 is the linkage structure schematic representation of elastomer and crank pin and joint balance piece among Fig. 1 embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawing example:
Among the embodiment as shown in Figure 1, originally the displacement vortex fluid compressor that has radial compensation mechanism is a scroll air compressor, and it is made of the housing end plug 7 of housing 1, fixed scroll 2, moving scroll 3, crosshead shoe 4, joint balance piece 5, end cap bearing 6, tape spool bearing, main shaft 8, balanced body 9, elastic component 10 and the bearing 11 etc. of band crank pin.
Its moving scroll 3 is connected on the crank pin of main shaft 88 by bearing 11 and joint balance piece 5, the crank pin of main shaft 8 is provided with a groove on its main shaft radial outer side, elastic component 10 is housed in this groove, and this elastic component is a wavy spring.
Shown in Figure 2, elastic component is to be contained in the gap of the crank pin of main shaft 8 and joint balance piece 5.
Fig. 1, when the scroll air compressor that Fig. 2 shows is worked, power is by main shaft 8 and joint balance piece 5, bearing 11 drives moving scroll 3 and makes revolution motion with respect to fixed scroll 2, the elastic force that elastic component 10 on the main shaft 8 produces passes on the moving scroll 3 by joint balance piece 5 and bearing 11, this power and moving scroll 3 equal or are slightly larger than joint balance piece 5 making centrifugal force sum that revolution motion produces, equilibrium centrifugation power that balanced body 9 is produced and hydrodynamic pressure sum, therefore, make the determined offset of revolution motion even also can guarantee moving 3 pairs of fixed scrolls 2 of scroll during low-speed running, thereby guarantee engagement well between the two, with anti-leak.
