The sectional view of compressor of the invention is shown please also refer to Fig. 4 and Fig. 5, Fig. 4, Fig. 5 is
Sectional view in Fig. 4 at A-A.It should be noted that compressor can be single cylinder compressor, it is also possible to
It is duplex cylinder compressor, in Fig. 4 and Fig. 5 by taking single cylinder compressor as an example, but is not limited thereto.Additionally,
To there is technical problem especially prominent in frequency-changeable compressor due to of the prior art, therefore, the present invention is real
The structure for applying example is mainly illustrated by taking frequency-changeable compressor as an example, but the invention be not limitedly applied to frequency conversion pressure
Contracting machine.
In the preferred embodiment shown in Fig. 4 and Fig. 5, compressor of the invention includes housing, motor 3
It is placed in the housing.Specifically, motor 3 includes being sheathed on internal rotor 32 on bent axle 31 and outer
Stator 33.External stator 33 is fixed with the housing.Internal rotor 32 is inserted in external stator 33, including
There is predetermined gap between rotor 32 and external stator 33, and then by the interaction with external stator 33
And rotate the internal rotor 32.Bent axle 31 is connected to the internal rotor 32 with by the revolving force of internal rotor 32
It is transferred in compression member, with compression refrigerant.As shown in Figure 4 and Figure 5, the top of bent axle 31 according to
Top support component 8 is positioned at the axis of the housing.The bottom of bent axle 31 relies on clutch shaft bearing 4
With the axis that second bearing 6 is positioned at the housing (reference can be made to hereafter).
The compression member is placed in the housing.Specifically, the compression member includes：Cylinder
51st, rotate piston 52, the blade 53 for completely cutting off high-low pressure chamber in cylinder 51 and for cylinder
51 limit compression strokes and support the clutch shaft bearing 4 and second bearing 6 of bent axle 31 jointly.
Clutch shaft bearing 4, second bearing 6 and cylinder 51 are located at the side of motor 3 to support bent axle 31,
Clutch shaft bearing 4 and second bearing 6 are respectively arranged at the two ends of cylinder 51, and clutch shaft bearing 4 is located at cylinder
51 near one end of motor 3.Clutch shaft bearing 4 includes second boss 42, and second boss 42 is towards motor
3 protrusions, clutch shaft bearing 4 constitutes friction pair by second boss 42 with bent axle 31.In Fig. 4 and Fig. 5
In shown embodiment, clutch shaft bearing 4, second bearing 6 and cylinder 51 are located at the lower section of motor 3.
Clutch shaft bearing 4 is arranged at the upper end of cylinder 51, and second bearing 6 is arranged at the lower end of cylinder 51.
Rotate piston 52 and blade 53 is arranged at cylinder 51 and is limited with clutch shaft bearing 4 and second bearing 6
Compression stroke in.Wherein, rotate piston 52 to be arranged on bent axle 31, rotated with bent axle 31, leaf
Piece 53 is located in blade groove (not shown), and supports rotation piston 52.
In order to solve occur during case weld of the clutch shaft bearing 4 present in prior art with compressor
Eccentric this problem (the i.e. center line of clutch shaft bearing 4 and bent axle 31, internal rotor 32 and external stator
The center line of 33 grade parts occurs to deviate, not point-blank).Compressor of the invention is to muffler
Improved.Specifically, muffler 2 includes side wall 21 and sound attenuating body 9.Such as Fig. 4 and Fig. 5
It is shown, side wall 21 as the housing of the compressor a part, the external stator 33 with motor 3 fixes
It is connected.Sound attenuating body 9 is arranged at the bottom of side wall 21, between motor 3 and the compression member,
It is connected with the clutch shaft bearing 4 of the compression member, for weakening the high speed from compression member outflow
The noise of gas.The upper/lower terminal of muffler 2 is respectively welded the upper lid 1 and lower cover 7 of the compressor.
One end that lower cover 7 is connected with muffler 2 is located at the periphery of sound attenuating body 9.Wherein, sound attenuating body 9 with
Side wall 21 is integrally formed, i.e., disposable punching press making, noise reduction are used between sound attenuating body 9 and side wall 21
Device 2 is overall to have no welding portion.
Please also refer to Fig. 6 to Fig. 7, which respectively show the vertical view of the muffler of compressor of the invention
Figure and sectional view.Specifically, sound attenuating body 9 includes a first boss 92, the direction of first boss 92
Motor 3 protrudes, and first boss 92 combines to form silencing cavity with clutch shaft bearing 4.As shown in fig. 6, the
One boss 92 is provided with some ventholes 93.Enter from the part high-speed gas of compression member outflow
Sound attenuating body 9, and from after the discharge of venthole 93, noise is attenuated, so as to reach noise reduction purpose.
As shown in Figure 6 and Figure 7, first boss 92 is provided with an axis hole 94, and axis hole 94 supplies bent axle
31 pass through.Specifically, please also refer to Fig. 4, axis hole of the second boss 42 through first boss 92
94, between first boss 92 and bent axle 31.Preferably, the first boss 92 of sound attenuating body 9
It is interference fit and the second boss 42 of clutch shaft bearing 4 between, makes the inner surface of first boss 92 and the
The outer surface of two boss 42 is closely affixed, to strengthen stability.
Preferably, it is bolt connection between sound attenuating body 9 and clutch shaft bearing 4.Sound attenuating body 9 is provided with
Some screws 91, screw 91 is screwed togather by bolt with clutch shaft bearing 4 so that first boss 92 and first
Bearing 4 forms the silencing cavity after connecting.
The periphery of sound attenuating body 9 is additionally provided with the waist hole 95 that multiple supplied gas pass through.
Further, because the side wall 21 of muffler 2 is formed in one with sound attenuating body 9, first axle
4 are held be connected with sound attenuating body 9 (do not welded with side wall 21), therefore, it is to avoid the pressure of prior art
The eccentricity issues that the clutch shaft bearing 4 ' that contracting machine is present is produced when being welded with the inwall of the compressor housing.
From the point of view of simulation calculation, preferably, its maximum defluxion is only the amount of deflection of bent axle after compressor assembling of the invention
0.063899mm.And then avoid external stator and internal rotor from occurring the unstable feelings of air gap in operation process
Condition, reduces compressor (especially frequency-changeable compressor) noise at high speed, meanwhile, the housing
Structure can also reduce waste material, reduce manufacturing cost.
In summary, the muffler of compressor of the invention is using side wall and the integrally formed knot of sound attenuating body
Structure, side wall as compressor housing a part, clutch shaft bearing is connected with sound attenuating body, without with housing
Inwall welding, it is to avoid the eccentric problem of clutch shaft bearing that the compressor of prior art is present, make bent axle
With good amount of deflection, and then it is unstable to avoid external stator and internal rotor from occurring air gap in operation process
Situation, reduces compressor (especially frequency-changeable compressor) noise at high speed, meanwhile, the structure
Compressor can also be made to reduce waste material during fabrication, reduce manufacturing cost.
