The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the sectional structure schematic diagram of the rolling rotor type compressor of prior art;
Fig. 2 is the sectional structure schematic diagram of the first embodiment according to rolling rotor type compressor of the present invention;
Fig. 3 is the sectional structure schematic diagram of the second embodiment according to rolling rotor type compressor of the present invention.
Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figures 2 and 3, the rolling rotor type compressor of the present embodiment comprises: have the housing 1 of upper cover 12, be arranged at motor 20 and the pump assembly 30 of housing 1 inside.Motor 20 comprises stator 21 and rotor 22, pump assembly 30 form primarily of bent axle 31, upper flange 32, cylinder 33, roller 34, lower flange 35.Wherein, bent axle 31 is driven by motor 20, under the support of upper flange 32 and lower flange 35, drive roller 34 to rotate in cylinder 33.Motor 20 comprises first end (first end is lower end in the specific embodiment shown in Fig. 2 with Fig. 3) and second end relative with first end, pump assembly 30 is arranged at the first end of motor 20, connected with motor 20 by bent axle 31, bent axle 31 to extend to the second end through motor 20 from the first end of motor 20 and has extension axle head, the compressor of the present embodiment also comprises limit position part 41, limit position part 41 is fixed in housing 1, be placed in the second end of motor 20, and bent axle 31 rotatably coordinates with limit position part 41.Limit position part 41 extends the radial motion of axle head for limiting.Arranging of limit position part 41 can play restriction positioning action to the crankshaft rotor system of compressor, ensures stators and rotators gap when compressor assembles, and reduces the swing of crankshaft rotor system when compressor operation, thus reduces noise and the vibration of compressor.
In an embodiment of the present invention, limit position part 41 comprises the joint be connected with housing 1 and the bent axle limited part supporting 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 Fig. 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.Now, as shown in Figure 2, on extension axle head, the oilhole 312 be 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.Particularly, oilhole 312 is positioned at below the plug cock 313 of the center oilhole 311 of shutoff shaft end.
Alternatively, compressor also comprises the bearing be arranged between the extension axle head of bent axle 31 and axis hole, extend axle head by bearings in the axis hole of bent axle limited part.Such as, rolling bearing can be pressed in axis hole, and make the extension axle head interference fit of rolling bearing and bent axle 31.
Concrete, in the first embodiment shown in Fig. 2, limit position part 41 is supporting disk, and the outer circumferential face of supporting disk is connected with housing 1 as joint.Wherein, supporting disk can adopt with housing 1 such as press-fit, the mode such as hot jacket or welding is connected.
Limit position part 41 is not limited to the form of supporting disk, and also can be support, support has one or more the link arm as joint.Preferably, link arm is multiple, makes multiple link arm be distributed between housing 1 and bent axle limited part equably, in this case, support and housing 1 also can adopt 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 bent axle 31, be not limited to axle and shaft hole matching one, such as, in the second embodiment shown in Fig. 3, at the bent axle limited part of limit position part 41, a cylindrical projection portion arranged with the central axis of bent axle 31 is set, and cylindrical projection portion and the axle end center hole concentric fit of extension axle head being arranged at bent axle 31.In order to ensure that cylindrical projection portion has enough intensity, the diameter of axle end center hole can be arranged be greater than the diameter of center oilhole.After arranging like this, the extension axle head of bent axle 31 can arrange shorter, and can cancel the plug cock 313 in the first embodiment.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect: because the crankshaft rotor system of limit position part to bent axle and rotor composition plays restriction positioning action, stators and rotators gap can be ensured when assembling, avoiding stuck and electromagnetism sound phenomenon; Reduce the swing of crankshaft rotor system when compressor operation, reduce bent axle amount of deflection, make compressor operation more steady, effectively reduce noise and the vibration of compressor.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, 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 amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
