Abstract

Disclosed is an eccentric rotator type compressor which can be used for refrigerating compressors, vacuum pumps, etc. The eccentric rotator type compressor comprises a case and an eccentric body. The eccentric rotator type compressor has the major technical characteristics that the compressor also comprises a big end cover fastened to the case, a rotor inserted on the eccentric body, blades A, B, and C which are respectively intercalated in the chutes A, B, and C of the rotor, two slide blocks intercalated respectively in the chutes A and B of the rotor, an elastic cushion, spacer block and a roller which are intercalated respectively in both ends of the blade A, the blade B, and the blade C, a bearing sheathed on the central axis of the rotor, and a seal ring intercalated in the small end cover of the case. The eccentric rotator type compressor has the characteristics low requirements for revolution speed, low resistance, etc.

Description

Eccentric rotator type compressor

The utility model relates to a kind of eccentric rotor formula compressor, and it can be used for refrigeration compressor, vacuum pump, hydraulic pamp, oil pressure pump etc.

In background technique, vane pump in the oil pressure pump of " non-standard equipment design handbook " the 3rd P65～66 page announcement that National Defense Industry Press publishes, though adopted the eccentric body structure, but because the restriction of other structure, there are defectives such as rotating speed requirement height, surface friction drag are big, poor sealing performance, for overcoming these defectives, it is improved.

The utility model purpose provides that a kind of rotating speed requirement is low, surface friction drag is little, the eccentric rotor formula compressor of good seal performance.

The utility model purpose is achieved in that

It comprises housing, embed housing and use the eccentric body of finger setting on housing, be fixed in the big end cap that on the housing eccentric body is compressed, insert on the eccentric body on its rotating disk in the eccentric hoop and eccentric body the center ring rotor of inscribe mutually, embed the blade first in the rotor upper hopper chute first, its big guide rod inserts the blade second in the embedding rotor upper hopper chute second in the big square hole on the blade first, its little guide rod inserts the blade third in the embedding rotor upper hopper chute third in the small square hole on the blade, embed rotor upper hopper chute second respectively, in the chute third with blade second, blade third contacted two slide blocks, embed blade first two ends respectively successively, cushion in the fork pockets on blade second and blade third and the slide block outer end, cushion block, roller, be placed on the rotor axis and embed in the housing bearing that the little end cap by housing compresses, pass the rotor axis and embed the seal ring that the small end in the housing covers.

Described rotor is the solid of rotation that is provided with axle, has the rotating disk of chute first, the chute second that is in 66 ° of distributions and chute third.

Described blade first is the rectangular plate that is provided with fork pockets, big square hole.

Described blade second is the rectangular plate that is provided with groove, small square hole, big guide rod.

Described blade third is for being provided with the rectangular plate of fork pockets, little guide rod.

Fig. 1 is a structural drawing of the present utility model.

Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.

Fig. 3 is the structure enlarged view of Fig. 1 rotor 1.

Fig. 4 is the structure enlarged view of eccentric body 20 among Fig. 1.

Fig. 5 is the structure enlarged view of blade first 3 among Fig. 1.

Fig. 6 is the structure enlarged view of blade second 6 among Fig. 1.

Fig. 7 is the structure enlarged view of blade the third 9 among Fig. 1.

Below in conjunction with accompanying drawing, the utility model is done to describe further:

Axle 21 on the motivational drive rotor 1 drives the blade first 3 that embeds on it, blade second 6, blade the third 9, roller 14 on the slide block 10 in the fork pockets 11 rotates on eccentric body 20 inwalls, center ring 16 and eccentric hoop 31 decentraction on the eccentric body 20, center ring 16 has certain throw of eccentric with rotor 1 top rotary table 15 on the eccentric body 20, the ascending formation negative pressure of volume, so under rotor 1 turning effort, fluid (gas or liquid) sucks from the inlet 25 on the housing 18, through inlet hole 26 on the eccentric body 20, enter suction area 27 in the center ring 16 on the eccentric body 20, in blade first 3, blade second 6, blade the third 9, under the effect of slide block 10 (slide block 10 is forced to elongate or shorten), volume is descending to be entered in the compressing area 28, discharge from the outlet 30 on the housing 18 through tap hole 29 on the eccentric body 20, and enter in the compression container, so constantly suck, compression.

The utility model is compared the good effect that produces with background technology:

1, the rotating speed requirement is low, wide accommodation, and rotating speed is directly proportional with lift.

2, the friction resistance is little, energy-conservation.

3, good seal performance is leaked little.
