Description
Technical field
What the present invention related to is blade rotary compressor, particularly be to reduce the friction reducing structure that rolls the blade rotary compressor that rubs between ring and the cylinder.
Background technique
Usually, compressor is to convert electrical energy into kinetic energy refrigerant is compressed.Compressor constitutes refrigerating circulation system with agglomerator, capillary tube, rapid steamer, and this refrigerating circulation system is installed in the devices such as refrigerator, air-conditioning.
In constituting the device of above-mentioned refrigerating circulation system, compressor is the parts of core the most, and its research-and-development activity is very many, and content is very abundant.
Fig. 1 and Fig. 2 are existing blade rotary compressor longitudinal sectional drawing and transverse cross-sectional view.As shown in the figure, blade rotary compressor comprises: seal container 10; Be installed on seal container 10 inside and be used to produce the drive motor 20 of rotating force; Form circular inner space P in inside, keep at a certain distance away with drive motor 20 and be combined in cylinder 30 in the seal container 10 with certain internal diameter; Form and to have the concentric eccentric part 41 of concentric mutually with rotating center and combine, make concentric eccentric part 41 be positioned at the running shaft 40 of the inner space P of cylinder simultaneously with drive motor 20; Cover upside and the downside and the combination of cylinder 30 respectively, main bearing 50 and auxilliary bearing 60 that the inner space P of cylinder 30 is sealed; Be inserted into the blade slot 42 in the concentric eccentric part 41 that is formed at running shaft, the blade 70 that the inner space P of cylinder 30 is separated; Be inserted into blade slot 42, be used for blade 70 is carried out the spring 80 of elastic support; Be used for the tap hole 51 that is formed at main bearing 50 is carried out the valve assembly body 90 of switch.
In above-mentioned seal container 10, connect the discharge tube 12 that is used to suck the suction pipe 11 of gas and is used to discharge gas respectively.
The different position, running shaft 40 centers that are centered close to of the inner space P of above-mentioned cylinder, and roll the inner space P that ring 100 will be inserted into cylinder 30, wherein roll ring 100 for to have the drum shape of certain-length and external diameter, roll the corresponding formation of internal diameter of external diameter with the inner space P of cylinder 30 of ring 100.Blade 70 carries out linearity with the inner side surface that rolls ring 100 and contacts, and blade 70 is supported by spring 80.Above-mentioned rolling encircled 100 frictions that can reduce between blade 70 and the cylinder interior space P inner peripheral surface.
Above-mentioned running shaft 40 with certain length comprises: the axial region 43 that combines with drive motor 20; The concentric eccentric part 41 that forms with external diameter and certain length in a side of axial region 43 greater than axial region 43; At the blade slot 42 of concentric eccentric part 41 with certain width and degree of depth formation.Wherein the center of eccentric part 41 is consistent with the center of axial region 43 with one heart, and blade slot 42 forms to the central direction of concentric eccentric part 41 at the outer circumferential face of concentric eccentric part 41.
The inside of above-mentioned main bearing 50 and auxilliary bearing 60 is inserted with running shaft 40, and main bearing 50 and auxilliary bearing 60 will support running shaft 40.Has the inlet hole 61 that is used for sucking gas in the auxilliary bearing 60 to the inner space of cylinder P.
The symbol that does not describe in the accompanying drawings is respectively: 11 are suction pipe, and 21 is stator, and 22 is rotor.
Below, the work of aforesaid blade rotary compressor is described.
At first, when compressor connection power supply, drive motor 20 is started working and is produced rotating force, and the rotating force of drive motor 20 is passed to running shaft 40 and makes running shaft 40 begin rotation.Along with the rotation of running shaft 40, the concentric eccentric part 41 of running shaft will be rotated at the inner space of cylinder P.
Gas is inhaled into the inner space P of cylinder by suction pipe 11 and inlet hole 61, will be discharged to the inside of seal container 10 by tap hole 51 along with the work of valve assembly body 90 at the compressed high temperature and high pressure gas of the inner space of cylinder P.Be discharged to the pressurized gas of seal container 10 inside, then will be discharged to the outside of seal container 10 by discharge tube 12.
In said process, the blade 70 of blade slot 42 that is inserted into the concentric eccentric part 41 of running shaft is along with the rotation of running shaft 40, with roll ring 100 state of contact and in blade slot 42, carry out the straight line back and forth movement.At this moment, will form airtight state between blade 70 and all bearings 50 and the auxilliary bearing 60, and the space that is positioned at above-mentioned blade 70 both sides will be configured for respectively sucks the suction space P1 of gas and be used for the compression volume P2 of pressurized gas.
Along with the concentric eccentric part 41 of above-mentioned running shaft rotates in the P of the inner space of cylinder, with one heart a side of eccentric part 41 peripheries and contacts side surfaces of rolling week in the ring 100, be inserted in the concentric eccentric part 41 blade 70 will with the inner peripheral surface state of contact of rolling ring 100 under be rotated.Thus, at the inner space P that is divided into two regional cylinders by concentric eccentric part 41 and blade 70, its volume separately changes and gas is sucked, compresses and action such as discharge.
At this moment, to slide with respect to the inner peripheral surface that rolls ring 100 with above-mentioned the ring 100 concentric eccentric parts 41 that contacts and be rotated and the blade 70 of rolling, and the outer circumferential face that rolls ring 100 will encircle 100 rotation and slide with respect to the inner peripheral surface of cylinder interior space P along with rolling.But roll between the inner peripheral surface of ring 100 outer circumferential face and cylinder 30 as shown in Figure 3, produce compressive force because of speed difference each other and cause friction to take place.Especially because roll ring 100 and cylinder 30 use metallic material making usually, therefore can produce problems such as noise and wearing and tearing because of the friction between the metal.
