Abstract
The utility model discloses a kind of novel compressor drum, comprise rotor subject and be arranged on the equilibrium area that hollows out on rotor subject, described in hollow out equilibrium area and comprise one or more grooves.Compressor drum of the present utility model, by the equilibrium area that hollows out that comprises groove is set on rotor subject, reduce the weight of rotor local, and groove is positioned at the opposite side special position of the original riveted master of rotor, top balance, make rotor and eccentric shaft formation assembly realize dynamic balancing.
Description
Technical field
The utility model relates to compressor field, particularly about novel compressor drum.
Background technique
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electric appliance of cooling cycle system work.The piston of compressor changes mechanical energy into pressure energy under the drive of motor, realizes the compression to compresser cylinder inner refrigerant.Motor converts electrical energy into mechanical energy by the rotation of corresponding part under current field effect, for the running of compressor provides power.
Motor is comprised of stator and rotor two-part, and the iron core that stator and rotor are formed by silicon steel core sheet stack respectively forms.Single stator iron core run-out is circular, and the stator iron core consisting of lamination stack is cylindric.Rotor is cylindric, and rotor is directly pressed on eccentric shaft and inserts in the cylinder cavity of stator iron core, between rotor and stator, has air gap to be separated by.On stator, embed the winding that enameled cable is coiled into, staor winding outside source current by time produce magnetic field.Rotor, when having electric current to pass through, interacts with stator field, produces electromagnetic torque and rotates in stator.
At present the air displacement of rotary compressor, be the design of refrigerating capacity size, be Method of Spreading Design according to the difference of the value size of the offset of eccentric pivoted cams; As Fig. 1 and Fig. 2, eccentric shaft is when High Rotation Speed, rotor 01 need to rely on balance to realize dynamic balancing with it, at increase top, the top of rotor 01 balance 02, in the bottom of rotor 01, increase main balance 03, balance and rotor, this assembly structure of eccentric shaft can be coordinated and stable rotation, guarantee the normal operation of compressor.For this settling mode, balance be riveted on rotor, not only to additionally buy balancing weight, and when rotor is produced reserved aluminium leg, but also to increase operation riveted balance to rotor; Its process route is complicated, and cost of production is higher, is unfavorable for mass production.In addition, due to balance be riveted epitrochanterian, when rotor high-speed rotates, the bad phenomenon that exists balance to come off.
Model utility content
In view of this, the utility model, for solving the problems of the technologies described above, provides a kind of novel compressor drum that carries equilibrium block.
The purpose of this utility model is achieved through the following technical solutions:
A novel compressor drum, comprises rotor subject and is arranged on the equilibrium area that hollows out on rotor subject, described in hollow out equilibrium area and comprise one or more grooves.
Described hollow out equilibrium area comprise be arranged on rotor top on hollow out district and be arranged on rotor bottom under hollow out district, hollow out district on described and comprise upper groove, hollow out district under described and comprise low groove.
The axis of the center line of described upper groove, the center line of low groove and described rotor subject is parallel to each other, and described upper groove and low groove are symmetrically distributed in the both sides of axis.
Described upper groove and low groove are arc groove, and the radian of described upper groove is for being equal to or less than 180 degree, and the radian of described low groove is for being equal to or less than 180 degree.
The utility model compared to the beneficial effect of prior art is:
Compressor drum of the present utility model, by the equilibrium area that hollows out that comprises groove is set on rotor subject, reduce the weight of rotor local, and groove is positioned at the opposite side special position of the original riveted master of rotor, top balance, make rotor and eccentric shaft formation assembly realize dynamic balancing; Compare with traditional increase master, the mode of top balance, by the mode of groove is set, reduce rotor local weight, realized equally assembly that rotor and eccentric shaft form when rotating in stable dynamic equilibrium state; By arranging of groove, substitute the mode of traditional riveted balance, both saved material, reduced raw-material cost, reduced again the riveted operation of balance, simplified production station, reduced manufacturing cost; The more important thing is, this novel compressor drum, the property retention of the mode of the dynamically balanced performance of the assembly that its stable rotor forms with eccentric shaft and traditional riveted balance is consistent, and the bad phenomenon that there will not be traditional balance to come off when rotor high-speed rotates, the rock-steady structure that has further guaranteed the assembly that rotor and eccentric shaft form, there will not be the phenomenon of damaging equilibrium structure along with the long-term rotation of rotor.

Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Please refer to Fig. 3-4, the utility model is embodiment comprise:
A novel compressor drum, comprises rotor subject 1 and is arranged on the equilibrium area that hollows out on rotor subject 1, hollows out equilibrium area and comprises a groove.
Compressor drum of the present utility model, by the equilibrium area that hollows out that comprises groove is set on rotor subject, reduce the weight of rotor local, and groove is positioned at the opposite side special position of the original riveted master of rotor, top balance, make rotor and eccentric shaft formation assembly realize dynamic balancing; Compare with traditional increase master, the mode of top balance, by the mode of groove is set, reduce rotor local weight, realized equally assembly that rotor and eccentric shaft form when rotating in stable dynamic equilibrium state; By arranging of groove, substitute the mode of traditional riveted balance, both saved material, reduced raw-material cost, reduced again the riveted operation of balance, simplified production station, reduced manufacturing cost; The more important thing is, this novel compressor drum, the property retention of the mode of the dynamically balanced performance of the assembly that its stable rotor forms with eccentric shaft and traditional riveted balance is consistent, and the bad phenomenon that there will not be traditional balance to come off when rotor high-speed rotates, the rock-steady structure that has further guaranteed the assembly that rotor and eccentric shaft form, there will not be the phenomenon of damaging equilibrium structure along with the long-term rotation of rotor.
