Embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figures 2 and 3, the rolling rotor type compressor of the present embodiment comprises: have the housing 1 of loam cake 12, the motor 20 that is arranged at housing 1 inside and pump assembly 30.Motor 20 comprises that stator 21 and rotor 22, pump assembly 30 mainly are comprised of bent axle 31, upper flange 32, cylinder 33, roller 34, lower flange 35.Wherein, bent axle 31 is driven by motor 20, drives roller 34 in cylinder 33 interior rotations under the support of upper flange 32 and lower flange 35.Motor 20 comprises first end (first end is the lower end in Fig. 2 and specific embodiment shown in Figure 3) and second end relative with first end, pump assembly 30 is arranged at the first end of motor 20, connect with motor 20 by bent axle 31, bent axle 31 passes motor 20 to the extension of the second end and has the extension axle head from the first end of motor 20, the compressor of the present embodiment also comprises limit position part 41, limit position part 41 is fixed in the housing 1, place the second end of motor 20, and bent axle 31 cooperates with limit position part 41 rotatably.Limit position part 41 is used for the radial motion that axle head is extended in restriction.Arranging of limit position part 41 can be played the restriction positioning action to the crankshaft rotor system of compressor, guarantees to reduce stator and rotor clearance the swing of crankshaft rotor system when compressor operation, thereby reduce noise and the vibration of compressor when compressor assembles.
In an embodiment of the present invention, limit position part 41 comprises the joint that is connected with housing 1 and the bent axle limited part that supports bent axle 31.But limit position part 41 also can be fixed on the stator 21 of motor 20 as required.
In the first embodiment shown in Figure 2, the bent axle limited part of limit position part 41 comprises axis hole, and the extension axle head of bent axle 31 is positioned at axis hole.
Alternatively, the extension axle head of bent axle 31 and axis hole Spielpassung.At this moment, as shown in Figure 2, the oilhole 312 that is communicated with the center oilhole 311 of bent axle 31 is offered in the position corresponding with the axis hole of bent axle limited part on the extension axle head.Particularly, oilhole 312 is positioned at plug cock 313 belows of the center oilhole 311 of shutoff shaft end.
Alternatively, compressor also comprises the extension axle head that is arranged at bent axle 31 and the bearing between the axis hole, extend axle head by bearings in the axis hole of bent axle limited part.For example, can in axis hole, be pressed into rolling bearing, and make the extension axle head interference fit of rolling bearing and bent axle 31.
Concrete, in the first embodiment shown in Figure 2, limit position part 41 is supporting disk, the outer circumferential face of supporting disk is connected with housing 1 as joint.Wherein, supporting disk and housing 1 can adopt such as press-fit, the mode such as hot jacket or welding is connected.
Alternatively, limit position part 41 can also be connected with housing 1 by connected element.
Supporting way between bent axle limited part and the bent axle 31, be not limited to axle and shaft hole matching is a kind of, for example, in the second embodiment shown in Figure 3, at the bent axle limited part of limit position part 41 the cylindrical projection section that a spigot shaft coaxle with bent axle 31 arranges is set, and cylindrical projection section and the axle end center hole concentric fit that is arranged at the extension axle head of bent axle 31.In order to guarantee that cylindrical projection section has enough intensity, the diameter of axle end center hole can be arranged greater than the diameter of center oilhole.After arranging like this, the extension axle head of bent axle 31 can arrange shortlyer, and can cancel the plug cock 313 among the first embodiment.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect: because limit position part plays the restriction positioning action to the crankshaft rotor system that bent axle and rotor form, when assembling, can guarantee stator and rotor clearance, avoid stuck and electromagnetism sound phenomenon; When compressor operation, reduce the swing of crankshaft rotor system, reduce the bent axle amount of deflection, make compressor operation more steady, effectively reduce noise and the vibration of compressor.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
