Crankshaft 31 passes through.Specifically, please also refer to Fig. 4, it is first convex to pass through sound attenuating body 9 for the second boss 42 of first bearing 4
Axis hole 94 on platform 92, between first boss 92 and crankshaft 31.Preferably, the first boss 92 and first of sound attenuating body 9
It is interference fit between the second boss 42 of bearing 4, keeps the inner surface of first boss 92 and the outer surface of second boss 42 close
It is affixed, to reinforce stability.
Further, in an embodiment of the present invention, it is connected between sound attenuating body 9 and first bearing 4 by locating piece.Tool
For body, as shown in fig. 6, first boss 92 further includes two contraction flow regions being oppositely arranged 921.Sound attenuating body 9 includes being located at the
The first screw hole 911 that two of one boss 92 are oppositely arranged, two the first screw holes 911 are located at two receipts of first boss 92
Contracting portion 921.It is correspondingly set with two the first screw holes 911 there are two third screw hole in first bearing 4, two bolts 96 are worn respectively
It crosses two the first screw holes 911 and is connected that (position of third screw hole can refer to first in Fig. 4 with the third screw hole in first bearing 4
The position of screw hole 911 and bolt 96), so that sound attenuating body 9 be made to be connected with first bearing 4.
Sound attenuating body 9 further includes around two the first concave stations 97 being oppositely arranged of 92 periphery of first boss and positioned at two
The second concave station 98 between a first concave station 97, the first concave station 97 and the second concave station 98 are connected to first boss 92 and side wall 21
Between bottom, lower than the first concave station 97, (namely the distance of bottom surface to the first boss 92 of the second concave station 98 is greater than the second concave station 98
The bottom surface of first concave station 97 to first boss 92 distance).First concave station 97 is assemblied in the top of first bearing 4 (such as Fig. 5 institute
Show).Second concave station 98 is assemblied between the periphery of first bearing 4 and the lower cover 7 of shell (as shown in Figure 4) so that muffler with
The connection of shell and first bearing is more firm.Second concave station 98 is equipped with multiple waist holes 95.
Sound attenuating body 9 further includes two the second screw holes 912 being oppositely arranged.Two the second screw holes 912 are located at two
First concave station 97.It is correspondingly set with two the second screw holes 912 there are two the 4th screw hole in first bearing 4, two bolts 96 divide
Not Chuan Guo two the second screw holes 912 be connected that (position of the 4th screw hole can refer in Fig. 5 with the 4th screw hole in first bearing 4
The position of second screw hole 912 and bolt 96).Preferably, two the second screw holes 912 are set to two 911 lines of the first screw hole
On vertical center line.It can be more effectively to first by the four point attachment of two the first screw holes 911 and two the second screw holes 912
Bearing 4 is leveled, to guarantee its concentricity.Wherein, leveling, which refers to, adjusts first bearing 4 and sound attenuating body 9 to substantially flat
Row, in turn, the central axes of the central axes and sound attenuating body 9 that make first bearing 4 are point-blank.
Further, it is integrally formed due to the side wall 21 of muffler 2 with sound attenuating body 9, first bearing 4 and sound attenuating body
9 are bolted and (do not weld with side wall 21), and bolt can effectively level first bearing 4, therefore, avoid existing skill
The eccentricity issues that the inner wall of first bearing 4 ' existing for the compressor of art and the compressor housing generates when welding, ensure that pressure
The concentricity of contracting machine.From the point of view of simulation calculation, the amount of deflection of crankshaft is preferable after compressor assembling of the invention, and maximum defluxion is only
0.063899mm.And then external stator and internal rotor is avoided to occur the unstable situation of air gap during operation, reduce compressor
The noise of (especially frequency-changeable compressor) at high speed, meanwhile, the structure of the shell can also reduce waste material, reduce manufacture at
This.
Second embodiment
Fig. 9 is referred to, it illustrates the top views of the muffler of the second embodiment of the present invention.With shown in above-mentioned Fig. 6
First embodiment unlike, sound attenuating body 9 only include two the first screw holes 911 being oppositely arranged, without include the second spiral shell
Hole 912.Specifically, as shown in figure 9, sound attenuating body 9 is only connect by the bolt at the first screw hole 911 with first bearing 4.It should
Embodiment can equally be achieved, and it will not go into details herein.
Referring to Figure 10, it illustrates the flow charts of the manufacturing method of compressor of the invention.Specifically, the present invention is gone back
A kind of manufacturing method of above-mentioned compressor is provided, as shown in Figure 10, the manufacturing method of the compressor includes the following steps:

The concentricity of contracting component.It should be noted that in second embodiment shown in Fig. 9, sound attenuating body 9 can also only by adjusting
The elasticity of the bolt of first 911 two different locations of screw hole levels first bearing 4, can equally be achieved,
It will not be described here.
Step S400: motor is cold-pressed in the side wall of muffler, is fixedly connected with the side wall of muffler, the motor position
In the other side of the sound attenuating body.In Fig. 4 and embodiment shown in fig. 5, motor 3 is located at the top of sound attenuating body 9, compression
Component is connected to the lower section of sound attenuating body 9.
Step S500: upper cover and lower cover are connected to the both ends of the muffler.Since the side wall 21 of muffler 2 is made
For a part of compressor housing, therefore, the upper cover and lower cover of compressor can directly be connect with muffler 2.Preferably, upper cover
1 and lower cover 7 be respectively welded in the upper/lower terminal of muffler 2.After lower cover 7 and muffler 2 weld, one end of welding, which is located at, to disappear
The periphery of sound main body 9.Compressor as shown in Figure 4 and Figure 5 can be formed after completing step S500.
It should be noted that the operation order in above-mentioned steps S400 and step S500 is only a preferred reality of the invention
Mode is applied, can be changed in other embodiments of the invention.For example, can be first by under after the completion of step S300
Lid 7 is weldingly connected with muffler 2, then carry out by motor be cold-pressed in the side wall of muffler and welding upper cover 1 the step of, the reality
Applying example can equally be achieved, and it will not be described here.
In summary, the muffler of compressor of the invention includes sound attenuating body and the side wall around sound attenuating body, is somebody's turn to do
The a part of side wall as compressor housing, first bearing and sound attenuating body are connect by locating piece (such as bolt), without with
The inner wall of shell welds, and avoids the problem of the bias of first bearing existing for the compressor of the prior art, ensure that compressor
Concentricity makes crankshaft have good amount of deflection, and then it is unstable to avoid external stator and internal rotor from occurring air gap during operation
The case where, the noise of compressor (especially frequency-changeable compressor) at high speed is reduced, meanwhile, which can also make compressor
Waste material is reduced during fabrication, reduces manufacturing cost.
