Specific embodiment
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As shown in figure 4, rotary compressor according to the present invention, including cylinder body 40 and shaft, shaft are concentric shafts, cylinder body
40 have cylinder chamber, and cylinder chamber is formed with respect to shaft eccentric setting, and between the internal perisporium of cylinder chamber and the periphery wall of shaft
Crescent working chamber A.The present invention is since shaft is concentric shafts, by cylinder chamber with respect to shaft eccentric setting, thus in cylinder chamber
Crescent working chamber is formed between internal perisporium and the periphery wall of shaft.Namely the present invention realizes rotation in removal rotor eccentricity portion
Compression can effectively reduce compressor noise so that pump housing operating can be relatively steady.
Specifically, sliding vane groove is provided in shaft, slide plate 50 is slidably disposed in sliding vane groove, is provided in sliding vane groove
Corresponding spring 70 so that the outer end of slide plate 50 be made to keep being bonded with the inner peripheral surface of cylinder chamber, and then crescent working chamber is divided
It is divided into suction chamber and compression chamber.
Preferably, in the present invention, since cylinder body 40 does not need setting sliding vane groove, cylinder body 40 can use Q shape cylinder body, have
Conducive to the volume for reducing compressor, so that compressor can smallerization.
Further, in conjunction with shown in Fig. 3 to 5, rotary compressor further includes upper flange 30 and lower flange 60, upper flange 30
With the multiple fixation holes 32 for being provided with the axis hole 31 and stationary housing 40 that cooperate with shaft on lower flange 60, multiple fixation holes
32 are distributed on the circumference of opposite shaft bias.Namely in the present invention, upper flange 30 and lower flange 60 and existing flange be not
Together, circumference locating for multiple fixation holes 32 and the decentraction of flange inner hole, fixation hole 32 are corresponding with the screw hole of cylinder.
It after assembly, is connected between upper flange 30 and lower flange 60 and cylinder body 40 for decentraction, upper flange 30 and lower flange 60
It is concentric connect with shaft；As shown in Figure 4,40 inner round wall of cylinder body and shaft cooperatively form crescent working chamber A, with the prior art
In compressor with rolling rotor crescent moon working chamber unlike, this month teeth cavity shaped position shape position during compressor operating
It sets and remains unchanged.Working principle diagram as shown in FIG. 6, crescent moon working chamber are divided into suction chamber and compression chamber by slide plate 50；Air-breathing
Mouth 41 is located at two sides at shaft and 40 minimum clearance of cylinder body with exhaust outlet；Slide plate 50 is translatable along sliding vane groove while rotating,
And it is in close contact under the pressure of spring 70 with 40 inner wall of cylinder body.Generally, air entry 41 is arranged on cylinder body 40, exhaust outlet
It is arranged on upper flange 30.
In the present invention, shaft can use integrated formed structure, i.e., axis platform is arranged in shaft and 40 corresponding part of cylinder body,
And sliding vane groove is set in axis platform.Certainly, as illustrated in fig. 1 and 2, shaft can also use the component of separate structure, i.e. shaft packet
Grooved hole 11 is arranged on axis body 10, is provided with and slot 11 on axle sleeve 20 for the axle sleeve 20 for including axis body 10 and being set on axis body 10
Corresponding through-hole 21, through-hole 21 can be nicked form, be also possible to punch format.Slot 11 and through-hole 21 cooperatively form slide plate
Slot.In conjunction with shown in Fig. 1 and 2, axis body 10 does not have eccentric part, is a uniform straight-bar, opens in axis body 10 and the matching part of axle sleeve 20
If a rectangular through-hole 21, axle sleeve 20 and the interference fit of axis body 10 and concentric fits, the purpose of interference fit are to prevent axle sleeve 20
It is relatively moved with axis body 10, through-hole 21 is set on axle sleeve 20 or notch requires to be aligned with the slot 11 on axis body 10, the two
Sliding vane groove is collectively formed, slot 11 can be through-hole, or blind hole.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
Rotary compressor according to the present invention, since shaft is concentric shafts, by cylinder chamber with respect to shaft eccentric setting, from
And crescent working chamber is formed between the internal perisporium of cylinder chamber and the periphery wall of shaft.Namely the present invention is in removal rotor eccentricity
Portion during rotating compression work, eliminates eccentric force, so that pump housing operating can be relatively steady, can effectively reduce compressor noise.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
