Description
Technical field
The present invention relates to a kind of anti-locking apparatus of scroll compressor, particularly relating to a kind of spool shape rotation preventer can reduce the spiral spool and put upside down moment, simultaneously, can improve the stability and the efficient of compressor, reduce rotation preventer because of the scroll compressor of concentrated friction that causes of local friction's power and noise.
Background technique
General so-called compressor is meant the compression set of fluids such as compression refrigeration gas, and it can be divided into rotary blade type compressor, reciprocating movement type compressor, scroll compressor etc. according to the different modes of compressor compresses fluid.
Above-mentioned spool type compressor is the compressor of the high efficiency low noise that widely utilizes in the air conditioner field, two spools of this kind compressor carry out relative turning motion, and having the plurality of compressed chamber between each spool forms a pair of, its working method is as follows, above-mentioned pressing chamber is inhaled into constantly, compresses, discharges along with volume reduces refrigeration agent to moving that central direction continues.
See also illustrated in figures 1 and 2ly, Fig. 1 is the sectional view that constitutes of scroll compressor in the past, and Fig. 2 is the schematic representation that constitutes of spool shape Oldham ' s ring in the past.
Shown in Fig. 1 to 2, compressor in the past comprises: cabinet 1, upper frame 2 and lower frame 2, drive motor 4, live axle 7, fixedly spool 5, spiral spool 6, Oldham ' s ring8, wherein, cabinet inside has airtight containing space, and a side has the sucking pipe SP and the outlet pipe DP of absorption, discharging refrigeration gas; Upper frame 2 and lower frame 3 are separately fixed at the both sides up and down of above-mentioned cabinet 1 inside; Drive motor 4 and be installed between above-mentioned upper frame 2 and the lower frame 3, thereby produce rotating force; When live axle is inserted in the gyrator 4b center of above-mentioned driving motor 4,, and combine, thereby transmit the rotating force that drives motor 4 with the screw shaft 6 that will be explained below by upper frame 2; Fixedly spool has the overcoat 5a of involute shape, is fixedly installed on the top of upper frame 2; The spiral spool has the overcoat 6a of involute shape, and matches with fixing spool 5, it is formed continue two a pair of pressing chamber P moving, and effect is by carrying out relative movement, compressed refrigerant with fixing spool 5; Oldham ' s ring 8 is arranged between above-mentioned spiral spool 6 and the upper frame 2, its role is to prevent carry out cycle under the situation of rotation of above-mentioned spiral screw 6.
Above-mentioned upper frame 2 central authorities have the axis hole 2a to radial direction supporting driving shaft 7, and the upper end portion of this axis hole 2a has the lug boss accepting groove 2b that the lug boss 6a that can make spiral spool 6 carries out turning motion.
Above-mentioned live axle 7 is inserted among the gyrator 4b, and both sides are supported by upper frame 2 and lower frame 3 respectively up and down, and its inside has the oil passageway 7a that axially extends, and its role is to absorb the machine oil of cabinet 1, lubricated each bearing surface.
Above-mentioned fixedly spool 5 combines with high low pressure separating plate 9, its role is to cabinet 1 inner space is divided into discharging compression volume Spd and sucks compression volume Spd.
The hardboard portion bottom surface of above-mentioned fixedly spool 5 has the overcoat 5a of two a pair of pressing chambers of formation P of involute shape, hardboard portion side has to pressing chamber P and sucks the suction port (not having diagram) that is drawn into the refrigeration agent that sucks compression volume Spd by sucking pipe SP, and the upper central of hardboard portion has the floss hole 5b that will discharging be discharged into discharging compression volume Spd by the pressurized gas of final pressing chamber P compression.
In addition, have check valve 10 above the above-mentioned fixedly spool 5, its role is to switch floss hole 5b selectively, and the adverse current phenomenon of the gas that prevents to freeze.
Has the overcoat 6a that together forms the involute shape of two a pair of pressing chamber P with the overcoat 5a of above-mentioned fixedly spool 5 above the hardboard portion of above-mentioned spiral spool 6, the bottom surface central authorities of hardboard portion have in above-mentioned live axle 7 and link to each other, can obtain the lug boss 6b of the driving force that drives motor 4, and this lug boss 6b is inserted among the lug boss accepting groove 2b of upper frame 2, thereby carries out turning motion.
Comprise in above-mentioned Oldham ' s ring 8 structures: circumferential body 8a, two upper lock 8b, two bottom lock 8c, wherein, two upper lock 8b protrude be formed on aforementioned body 8a above, form straight line, effect is to retrain moving along the spiral spool 6 of spiral spool 6 circumferencial directions; Two bottoms lock 8c protrude the bottom surface that is formed at main body 8a, form straight line, make its towards with the upper lock 8b direction of orthogonal mutually, thereby constraint moving along the main body 8a of spiral spool 6 circumferencial directions.For this reason, the bottom surface of above-mentioned spiral spool 6 has and comprises the top locked groove 6c that accommodates each upper lock 8b, has above the above-mentioned upper frame 2 to comprise the bottom locked groove 2c that accommodates each bottom lock 8c.
In addition, drawing symbol 4a represents to drive the stator of motor 4.
Below the as above running structure of the scroll compressor in the past of structure of following explanation.
When driving motor 4 connection power supplys, when live axle together rotates with the gyrator 4b that drives motor 4, spiral spool 6 will pass through Oldham ' s ring 8 and be rotated motion on upper frame 2 in eccentric distance, simultaneously, spiral spool 6 is fixedly continuing to form a pair of pressing chamber P between spool 5 and overcoat 5a, the 6a, and this pressing chamber P will move to the center by the turning motion that continues of spiral spool 6, and along with volume reduces, refrigeration gas continues to be inhaled into, compresses, discharges.
At this, refrigeration gas is inhaled into by sucking pipe SP and sucks compression volume Spd, be inhaled into pressing chamber P by suction port again, after being compressed, be discharged into discharging compression volume Spd by the fixing floss hole 5b of spool 5, after this, this refrigeration gas is discharged into refrigerating circulation system (not having diagram) by outlet pipe DP.
Otherwise, machine oil is when live axle 7 high speed rotating, oil passageway 7a by live axle 7 is absorbed into the upper end by center of circle power, when a part is lubricated the axis hole 2a of upper frame 2, another part is supplied between the thrust bearing surface of the thrust bearing surface of spiral spool 6 and upper frame 2, is lubricated effect.
But, in the past scroll compressor only on main body and below have lock 8b, the 8c of two Oldham ' s ring 8 that prevent to be rotated under the situation of spiral spool 6 rotations respectively, when moment is put upside down in generation, moment is disperseed here, make on its each lock 8b, 8c that focuses on Oldham ' s ring8, Oldham ' s ring 8 is tilted, and spiral spool 6 has the potential risk that can put upside down, thereupon, the Security of compressor and efficient reduce greatly.
Simultaneously, put upside down the lock 8b that moment focuses on Oldham ' s ring8 as mentioned above, on the 8c, thereupon because of the concentrated friction and the noise of having increased of local friction's power.
This shows that the rotation preventer of above-mentioned existing scroll compressor obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.The problem that exists for the rotation preventer that solves scroll compressor, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
