Description

Rotor assembly and motor

Technical field

The utility model relates to field of refrigeration equipment, in particular to a kind of rotor assembly and motor.

Background technique

The main function of refrigerator oil in compressor is lubrication, sealing etc., however, in compressor operation, especially When frequency-changeable compressor high frequency is run, since extraction flow is larger, refrigerator oil is easy to be discharged to pressure along exhaust pipe with refrigerant Outside contracting machine, so as to cause compressor inside oil starvation, lack of lubrication is caused, influences compressor reliability of operation, while excessively Refrigerator oil enters air-conditioning system, reduces the heat exchange property of air-conditioning system, and the efficiency of air-conditioning system is caused to reduce.

The rotor assembly inside compressor is mainly by iron core, magnet, upper and lower end plate, upper and lower balance weight and rivet group at present At, and upper and lower balance weight and upper and lower end plate are separately fixed at the axial ends of iron core using rivet, thus play it is fixed it is upper, The effect of bottom plate and upper and lower balance weight.In order to reduce the oil spitting amount of compressor, the top of general upper balance weight is arranged one again Oil baffle keeps air-flow radially exiting, thus the refrigerator in air-flow to change the direction from rotor assembly iron core discharge air-flow Oil can be got rid of under the influence of centrifugal force to motor stator coil, to have the function that reduce oil spitting amount.But due to oil baffle It needs to be installed in plane, it is therefore desirable to three supporting blocks concordant with upper balance weight upper surface are additionally set on end plate, therefore Lead to rotor assembly structure is complicated, higher cost, assembly it is more difficult.

Chinese patent Authorization Notice No. CN206221268U discloses a kind of rotor assembly, motor, compressor and refrigeration system System, though can reach, rotor component construction is simple and easy to process and assembly, and be effectively reduced compressor spits oil cut rate.So And in practical application, because pod is arranged on end plate, the diversion outlet of pod is radially outward opening wide along iron core, Refrigerant and refrigerator oil can be flowed out from diversion outlet, therefore when rotor assembly operating, the flow direction of refrigerant can be with the rotation side of rotor It is interfered to being formed, therefore causes the increase of refrigerant flow resistance.

In order to solve the above-mentioned technical problem, the utility model provides a kind of rotor assembly, comprising: an iron core, iron core have One first end and a second end are formed with multiple first through hole and multiple mounting holes, the both ends point of multiple first through hole on iron core Not Guan Chuan iron core first end and second end；Multiple magnet, multiple magnet are respectively arranged in multiple mounting holes；End plate, end Plate is set to the first end of iron core, and multiple second through-holes are formed on end plate, and multiple second through-holes penetrate through end along upper and lower direction Plate, and multiple second through-holes are connected with multiple first through hole respectively；And multiple pods, multiple pods are set to end plate In one side far from iron core, a diversion cavity is defined between each pod and end plate, diversion cavity is connected with the second through-hole, often A diversion outlet is defined between one pod part edge and end plate, diversion outlet is connected with diversion cavity, diversion outlet court An export direction open wide, the edge of rotor assembly corresponds to direction and the exporter of the tangential velocity of the nearest point of diversion outlet To being parallel to each other and be reversed.

Preferably, an outlet end is formed in the outside of diversion outlet on pod, outlet end is located at the edge of pod, out Extension line the radially extending towards rotor assembly at mouth end.

Preferably, the axle center that the extension line of outlet end passes through rotor assembly.

Preferably, multiple pods are equally spaced is located in the one side of end plate.

It preferably, further include a clump weight, clump weight is set in the one side of separate iron core of end plate.

Preferably, clump weight is located at the outside spacers of multiple pods of part, the axle center of clump weight and rotor assembly Spacing be greater than part multiple pods and rotor assembly axle center spacing.

Preferably, the arc-shaped shell of pod, pod have an inner surface and an outer surface, and inner surface is close to water conservancy diversion Chamber, outer surface are curved surface far from diversion cavity, the inner surface of pod.

In order to solve the above-mentioned technical problem, the utility model also provides a kind of motor, comprising: a foregoing rotor set Part and stator group part.Rotor assembly is set to the inside of stator module, the rotation of rotor assembly energy relative stator component.

The utility model has the following beneficial effects:

In being arranged multiple pods on end plate in the utility model rotor assembly, the diversion outlet of multiple pods respectively towards One export direction opens wide, and the edge of rotor assembly corresponds to direction and the export direction of the tangential velocity of the nearest point of diversion outlet It is parallel to each other and is reversed.Therefore multiple pods can carry out gentle guide functions to refrigerant, and reduce the stream of refrigerant Dynamic resistance, and the problem of improve oil spitting amount of compressor, promote compressor efficiency, and need not high-precision processing and assembling skill Art.

Since the diversion outlet of pod is opened wide towards export direction, it is nearest that the edge of rotor assembly corresponds to diversion outlet Point tangential velocity direction and export direction be parallel to each other and be it is reversed, therefore refrigerant flow to will not with rotor assembly turn Dynamic direction forms interference, in turn results in the increase of refrigerant flow resistance, therefore oil recycle ratio effect is preferable.
