Embodiment
The present invention first purpose be to provide a kind of rotor, the structure design of the rotor can be effectively reduced motor Windage loss, second object of the present invention is to provide a kind of compressor including above-mentioned rotor and including above-mentioned compressor Air conditioner.
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work Embodiment, belongs to the scope of protection of the invention.
- Fig. 6 is please referred to Fig.1, rotor provided in an embodiment of the present invention includes rotor body 2, aluminum strip and two end ring 4, its In two end ring 4 be separately positioned on the both ends of rotor body 2, be provided with along its circumferentially uniformly distributed multiple master and turn on rotor body 2 Aluminum strip is provided with pilot trench 2a, main rotor groove 2a.Focus on, rotor body 2 is divided to for two by the plane for crossing 2 axis of rotor body Part, and two parts are respectively Part I and Part II, i.e., the planes of rotor axis rotor body 2 is bisected into two Point.And secondary rotor slot 2b is additionally provided with Part I or Part II, i.e., on one in Part I and Part II It is provided with main rotor groove 2a and secondary rotor slot 2b, main rotor groove is provided only with another in Part I and Part II 2a.And main rotor groove 2a and pair rotor slot 2b be through slot, main rotor groove 2a and pair rotor slot 2b each along parallel to turn Sub- 2 axially direction of body perforation, i.e. main rotor groove 2a and pair rotor slot 2b extend to another by one end of rotor body 2 Aluminum strip is both provided with end, main rotor groove 2a and secondary rotor slot 2b.
In rotor provided in an embodiment of the present invention, secondary rotor slot 2b is set in the side of rotor body 2, and in secondary rotor Aluminum strip is set in groove 2b, and rotor body 2 is generally silicon steel material, so different from the density of silicon steel using aluminium, makes rotor body 2 Both sides vary in weight so that rotor is uneven in itself, during assembling, make secondary rotor slot 2b and bent axle 1 away from axial line distance Larger side is respectively positioned on the same side, so ensure that rotor and bent axle 1 balance.The volume size of secondary rotor slot 2b can basis The eccentricity of bent axle 1 is set in actual conditions.In technical solution provided by the invention, it is not necessary to equal at 2 both ends of rotor body again The larger balance weight of volume is set, and then avoids the dielectric frictions such as the larger balance weight of volume and refrigerant, rise it is hot larger and The situation of the windage loss of motor can be increased.Moreover, in technical solution provided by the invention, the area of section of aluminum strip is added, And then improve the efficiency of compressor electric motor.
As shown in Figure 2 and Figure 4, rotor body 2 is bisected into two parts along A-A planes, and pair is provided with a portion Rotor slot 2b.
In order to further optimize above-mentioned technical proposal, as shown in Fig. 2, the quantity of wherein secondary rotor slot 2b can be multiple, And multiple pair rotor slot 2b are evenly distributed with Part I or Part II along the circumferential direction of rotor body 2.I.e. multiple secondary rotors Groove 2b is evenly distributed with along the semicircle camber line in Part I or Part II, so that the stress of rotor body 2 is more balanced, is rotated During more stablize.Certainly, as shown in figure 3, multiple pair rotor slot 2b lines can also be along Part I or Part II The interior camber line less than semicircle is evenly distributed with, and is not limited thereto.
It should be noted that pair rotor slot 2b can be circular groove, square groove or oval groove, herein not to secondary rotor slot 2b's Groove profile makees specific limit.Certainly, main rotor groove 2a can also be circular groove, square groove or oval groove, be not limited thereto.
In order to ensure the intensity of rotor body 2, wherein secondary rotor slot 2b can be located at the inner side of main rotor groove 2a, i.e., it is secondary to turn The distance of axis of the pilot trench 2b away from the rotor body 2 is less than the distance of axis of the main rotor groove 2a away from rotor body 2.
For the ease of processing and manufacturing, wherein end ring 4 can be aluminium ring, and end ring 4 and aluminum strip can pass through a die casting Formed.
In order to ensure the efficiency of compressor electric motor, end ring 4 can be aluminium ring, and the end face of end ring 4 can cover main turn The notch of the notch of pilot trench 2a and secondary rotor slot 2b.Aluminum strip and end ring 4 i.e. in main rotor groove 2a and secondary rotor slot 2b is equal Contact.
In addition, setting secondary rotor slot 2b on Part I, and secondary balance weight 3 is additionally provided with Part I, you can with Pair rotor slot 2b and secondary balance weight 3 are set over the first portion at the same time, secondary balance is preferably only set in one end of Part I Block 3.So eccentricity for coordinating common equilibrium bent axle 1 of pair balance weight 3 and secondary rotor slot 2b, secondary balance weight 3 and the prior art The balance weight of middle setting compares small volume, therefore will not produce larger windage.
For the ease of processing and manufacturing, end ring 4 be aluminium ring, and secondary balance weight 3 is aluminium block, and aluminium ring, pair balance weight 3 and aluminum strip can be with Formed by a die casting.Certainly, end ring 4 and secondary balance weight 3 can also be other materials, be not limited thereto.
Based on the rotor provided in above-described embodiment, present invention also offers a kind of compressor, which includes above-mentioned Any one rotor in embodiment.The rotor in above-described embodiment is employed due to the compressor, so the compressor is beneficial Effect refer to above-described embodiment.Present invention also offers a kind of air conditioner including above-mentioned compressor, therefore the air conditioner Beneficial effect refer to above-described embodiment, not repeat herein.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other The difference of embodiment, between each embodiment identical similar portion mutually referring to.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or use the present invention. A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention The embodiments shown herein is not intended to be limited to, and is to fit to and the principles and novel features disclosed herein phase one The most wide scope caused.
