Abstract
The invention discloses a kind of Linearkompressor and electric machine fixation structure, including inner stator, cylinder and forward flange, at least partly there is gap between cylinder and inner stator.Linearkompressor and electric machine fixation structure of the present invention, boss play positioning and supporting role to inner stator, and in fixed inner stator, cylinder need not be in close contact with inner stator, reduce magnetic field and pass through loss caused by cylinder.
Description
Technical field
The present invention relates to a kind of Linearkompressor, especially with respect to the motor part of Linearkompressor, particularly stator phase
For the fixed form of cylinder.
Background technology
Linearkompressor is the driving force that linear fashion is converted electrical energy into using linear electric machine, and driving piston is realized linear
Move back and forth, and then the device of compressor work is realized in compression refrigerant or the acting of other media.As shown in Figure 1, usual line
Property compressor includes：Shell 1（Outer casing bottom generally accommodates lubricating oil）, linear electric machine (include external stator 2, inner stator 3,
Be wound with not shown in bobbin-figure of coil), forward flange 4, in the presence of linear motor driving force movement under force mover
7th, by mover 7 drive after move back and forth realize acting piston 5 and coordinate acting cylinder 6, mover 7 move back and forth constantly and
Preceding resonant spring 8 and rear resonant spring 9, the oil pump component for compressor friction part fuel feeding and the suction being stretched when being extruded
The parts such as exhaust apparatus（It is to mark out in figure）.
Existing Linearkompressor, the fixation to motor, the inner stator 3 nearer from cylinder is typically passed through press fitting（Cross
It is full of cooperation）Mode be fixed on the external cylindrical surface of cylinder 6.But this structure, it is desirable to which cylinder dimensions are longer.But due to
Cylinder is made by materials such as the strong cast irons of magnetic conductivity, in the case of being in close contact with inner stator 3, there is magnetic field inside inner stator
When flowing through, partial magnetic field can flow through cylinder 6, cause the unnecessary magnetic loss of cylinder 6, so as to reduce electric efficiency.But for
Cylinder 6, which is insufficient to long structure i.e. cylinder 6, need not run through the structure of stator body, or not need stator and cylinder interference fit
Structure, existing Linearkompressor structure obviously can not realize effectively fix motor.In addition, mentioning in the prior art, such as adopt
When fixing the frame mode of motor with bolt, want to be fixed with bolt exactly, stator need to first be positioned, but existing compressor knot
There is no location division in structure, bolt hole can not be beaten and be attached.
The content of the invention
In view of this, the technical problem to be solved in the present invention is to provide a kind of Linearkompressor and motor fixed knot
Structure, in fixed inner stator, it is arranged at intervals between inner stator and cylinder, reduces magnetic loss.
In order to solve the above technical problems, the technical proposal of the invention is realized in this way：A kind of motor of Linearkompressor
Fixed structure, including inner stator, cylinder and forward flange, at least partly there is gap between the cylinder and inner stator.
Further, the inner stator is connected on cylinder by holding section.
Further, the holding section include be arranged on the boss on cylinder and on the inner stator with the boss pair
The recessed conjunction portion that should be opened up.
Further, the boss is positioned close to the cylinder front end of forward flange.
Further, the boss is integrally formed with cylinder.
Further, it is additionally provided with retainer ring on the outside of the cylinder rear end away from forward flange.
Further, the second recessed conjunction portion is provided with the inner stator corresponding with retainer ring.
Further, the boss, retainer ring, cylinder and forward flange at least one use non-magnet material.
Further, connected between the cylinder and inner stator by being interference fitted.
The present invention also provides a kind of Linearkompressor, and the Linearkompressor includes above-mentioned electric machine fixation structure.
The technique effect that the present invention reaches is as follows：1st, Linearkompressor and electric machine fixation structure of the present invention, inner stator and
At least partly there is gap between cylinder, be provided with boss in cylinder, cylinder need not be in close contact with inner stator, reduced magnetic field and passed through
Lost caused by cylinder.2nd, forward flange and cylinder are made of non-magnet material, and magnetic loss is further greatly lowered.
Brief description of the drawings
Fig. 1 is the structural representation of existing Linearkompressor；
Fig. 2 is the structural representation that the present invention fixes in cylinder and inner stator.
Embodiment
As shown in Fig. 2 Linearkompressor include shell 1, external stator 2, inner stator 3, forward flange 24, in linear compression motor
The mover 7 of movement under force in the presence of driving force, the piston 5 for realizing acting is moved back and forth after being driven by mover and coordinates acting
Cylinder 16 and when mover 7 moves back and forth, when and be extruded or when and the preceding resonant spring 8 and rear resonant spring 9 that are stretched.
As shown in Fig. 2 be Linearkompressor of the present invention and its fixed structure of motor, including inner stator 3, cylinder 16 and
Forward flange 24, inner stator 3 are connected on cylinder 16 by holding section, at least partly there is gap 10 between cylinder 16 and inner stator 3.
Gap 10 between cylinder 16 and inner stator 3 can greatly reduce magnetic loss, so as to improve operating efficiency, save electric energy.At this
In embodiment, holding section include the boss 161 that is arranged on cylinder and on inner stator 3 it is corresponding with boss 161 open up it is recessed
Conjunction portion, boss 161 are most preferably positioned close to the front end of cylinder 16 of forward flange 24, also may be used in the rear end of cylinder 16 away from forward flange 24
Retainer ring 162 is additionally provided with, for being further fixedly connected with inner stator 3.Retainer ring 162 can be independently arranged, and set is attached to cylinder
16 outsides, can also be integrally formed with cylinder 16, can also be fixed using other modes, such as welding etc..In addition, in inner stator
The position of retainer ring 162 is corresponded on 3 can set the second recessed conjunction portion, consequently facilitating assembling, accurate positioning, and in the course of work
It is middle to keep reliable and stable, it will not be subjected to displacement because of reasons such as vibrations.Using interference fit between inner stator 3 and cylinder 16.It is convex
At least one uses non-magnet material for platform 161, retainer ring 162, cylinder 16 and forward flange 24, certainly, preferably all adopts
It is made of non-magnet material.Boss 161 can be integrally formed with cylinder 16, can be also connected to using other modes on cylinder 16,
Such as weld mode.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
