Abstract
The invention discloses a connecting structure between a motor rotor of a compressor and a counterweight. The connecting structure comprises a rotor and the counterweight, wherein two aluminum posts are formed at the top of the rotor; a cambered heave is formed between the two aluminum posts; two through-holes are formed on the two ends of the counterweight; a cambered groove is formed between the two through-holes. In the invention, not only the two aluminum posts and the two connecting holes of the counterweight are matched and connected with each other, but also the cambered heave on the end of the rotor is inserted into the cambered groove of the counterweight, so as to ensure firmer, safer and more stable connection between the motor rotor and the counterweight.
Description
Technical field
The invention belongs to the syndeton of a kind of rotor and balance weight, be specifically related to the syndeton of a kind of compressor rotor and balance weight.
Background technology
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electrical appliance of cooling cycle system work.The moving piston of compressor (rolling piston or reciprocating piston) changes mechanical energy into the pressure energy under the drive of motor, realize the compression to the compresser cylinder inner refrigerant.Motor converts electrical energy into the rotary machine energy by the rotation of corresponding component under the current field effect, for the running of compressor provides power.Therefore, motor is the vitals of compressor, and its behavior in service directly influences the function performance of compressor.
In general, motor is made up of stator and rotor two parts, and stator and rotor are made of the iron core that the folded collection of silicon steel core sheet forms respectively.Single stator lamination is circular, and the stator core that is made of the folded collection of lamination is cylindric.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the cylinder cavity of stator core, has air-gap to be separated by between rotor and the stator.Embed the winding of enamelled wire coiled on the stator, stator winding outside source current by the time produce magnetic field.Rotor interacts with stator field when having electric current to pass through, and the generation electromagnetic torque also rotates in stator.
The household electrical appliance that power is slightly little as window air conditioner, wall-hanging air conditioner etc., adopt monophase machine mostly.Be not with the enamelled wire winding on the monophase machine rotor, the electric current in the rotor is not supplied with by external power, but induce by stator field.Induced current and former magnetic field interaction make rotor rotation.
As shown in Figure 1, be moment of torsion that increases rotor and the dynamic balancing of keeping the rotation rotor, additional balance weight on the rotor, stator 1 embeds enamelled wire winding 2 in the form of a ring on the stator 1, and the top of rotor 3 is provided with balance weight 4, and balance weight 4 places the outer circumferential edge on rotor 3 tops.Balance weight 4 is set on the rotor 3 has also increased the moment of torsion of rotor 3.
Shown in Fig. 2,3, balance weight 4 is circular-arc, forms two connecting holes 5 at the two ends of balance weight 4.Rotor 3 is the cylindric of hollow, and hollow parts is installed rotating shaft (not shown), is provided with two aluminium posts 6 corresponding with two connecting holes 5 of balance weight 4 at the top of rotor 3, and connecting hole 5 and aluminium post 6 are worked in coordination, and balance weight 4 are fixed on the top of rotor 3.
But the rotor of prior art and the syndeton of balance weight have following shortcoming:
Because speed is very high during motor rotation, balance weight is subjected to very big centrifugal action, but the aluminium post intensity of stable equilibrium piece is limited, and adding man-hour because misoperation, the root of aluminium post and rotor junction ruptures easily, if at this moment an aluminium post has broken, balance weight can be thrown out of, and causes motor to damage.
Summary of the invention
The present invention proposes in order to overcome shortcoming of the prior art, its objective is the syndeton that a kind of rotor and balance weight are provided, and makes rotor more firm with being connected of balance weight.
Technical scheme of the present invention is: the syndeton of a kind of compressor rotor and balance weight, comprise rotor and balance weight, two aluminium posts are formed on the top at rotor, between two aluminium posts, form arc convex, two ends at balance weight form two through holes, form arc groove between two through holes.
Balance weight is circular arc, and two aluminium posts and two through holes are worked in coordination, and arc convex and arc groove are worked in coordination.
Rotor, two aluminium posts and arc convex are integrally formed, and balance weight, two through holes and arc groove are integrally formed.
The syndeton of rotor of the present invention and balance weight, not only two connecting holes of two of rotor tip aluminium posts and balance weight are connected.And the bossing of rotor tip is inserted in the groove of balance weight, can balance centripetal force of piece when motor rotation, all is added on two aluminium posts and be unlikely to all centrifugal force, makes rotor and being connected of balance weight more firm, safe and reliable.

Embodiment
Below, be elaborated with reference to the syndeton of drawings and Examples to compressor rotor of the present invention and balance weight:
Shown in Fig. 4～5, the syndeton of a kind of compressor rotor and balance weight: comprise rotor 7 and balance weight 8, form two aluminium posts 9, between two aluminium posts 9, form arc convex 10 at the top of rotor 7.Balance weight 8 is circular arc, forms two through holes 11 at the two ends of balance weight 8, forms arc groove 12 between two through holes 11.Two aluminium posts 9 and two through holes 11 are worked in coordination, and arc convex 10 and arc groove 12 are worked in coordination.
After being installed on the rotor 7, form flange 13 at the top of aluminium post 9 again to balance weight 8.
The syndeton of rotor of the present invention and balance weight, not only two connecting holes of two of rotor tip aluminium posts and balance weight are connected.And the bossing of rotor tip is inserted in the groove of balance weight, can balance centripetal force of piece when motor rotation, all is added on two aluminium posts and be unlikely to all centrifugal force, makes rotor and being connected of balance weight more firm, safe and reliable.
