Abstract
The utility model discloses a formula structure is buryyed to balancing piece, it sets up on the rotor of motor, the rotor includes the end links, formula structure is buryyed to balancing piece still includes the balancing piece, have sunkenly on the end links, the balancing piece set up in just bury on the end links it is sunken. The utility model discloses bury the balancing piece in electric motor rotor's the end links to guarantee balancing piece outer end surface no longer than end links outer end surface, thereby reduced the hot jacket height, increase end links NULL, improve rotor efficiency.
Description
Technical field
The utility model relates to a kind of electric machine structure, particularly relates to a kind of balance weight embedded structure.
Background technology
Current, existing constant speed rotor, all protrudes outside rotor tip, Fig. 1 is the structural representation of constant speed rotor balance 1 in prior art, as shown in Figure 1, adopts rotor structure of the prior art, hot jacket height cannot decline, and produces disturbance in motor rotation to compressor air-discharging.
In addition, application number: the utility model patent of 201220417140.5 discloses a kind of compressor of air conditioner balancing rotor, specifically disclose: the upper end of described rotor body is or/and bottom comprises and the stamping forming balance weight of rotor body one punching, described end ring is arranged on described balance weight, is also that the upper end of described balance weight and rotor body is or/and bottom is all positioned at inside end ring.Although this structure can reduce the disturbance to air, but due to its adopt be balance weight and rotor core one structure, adding man-hour, rotor body upper end is needed to be processed into step-like, its manufacture craft realizes comparatively complicated, and in addition, the rotor core that different machine adopts exists different, need to design different iron core and rotor die casting component for different machine, so poor universality.
Therefore, those skilled in the art is devoted to develop a kind of constant speed rotor balance embedded structure.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of balance weight embedded structure, it is arranged on the rotor of motor, described rotor comprises end ring, described balance weight embedded structure also comprises balance weight, described end ring caves in, and described balance weight to be arranged on described end ring and to imbed described depression.
Further, the form fit of described depression and described balance weight.
Further, described balance weight is different from the material of described end ring; Such as, described end ring is aluminium ring, and described balance weight adopts potassium steel block or copper billet.
Further, described balance weight is riveted on described end ring.
Further, described rotor comprises two described end ring and two described balance weights, and described two balance weights are imbedded in the depression of described two end ring respectively.
Further, the thickness of described balance weight is no more than the degree of depth of described depression.
Balance weight is imbedded in the end ring of rotor by the utility model, reduces hot jacket height, increases end ring material consumption, improves rotor efficiency.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art rotor balance weight;
Fig. 2 is that the balance weight embedded structure of the utility model embodiment is installed in the epitrochanterian structural representation of motor constant-speed forward.
Embodiment
Fig. 2 is the structural representation that the balance weight embedded structure of the utility model embodiment is arranged on rotor.As shown in the figure, the rotor that the balance weight embedded structure of the present embodiment is housed comprises end ring 2, also comprise balance weight 3, end ring 2 has the depression with balance weight 3 form fit, balance weight 3 to be arranged on end ring 2 and to imbed in depression, owing to adopting the structure of flush type, makes balance weight 3 to produce flow perturbation, reduce hot jacket height, and the axial stress of rotor can be reduced.
More specifically, end ring 2 of the present utility model is aluminium ring, and balance weight 3 can adopt potassium steel block.In other embodiments of the present utility model, balance weight 3 can also adopt copper billet.Those skilled in the art should know and know, as long as the material that balance weight 3 adopts is different from the density that end ring 2 adopts, end ring 2 and balance weight 3 can adopt other materials except upper listed concrete example completely.
More specifically, in the present embodiment, end ring 2, balance weight 3 all have two, and two end ring 2 are set in the two ends of rotor respectively, and two balance weights 3 are imbedded in the depression of two corresponding end ring 2 respectively.In other embodiments of the present utility model, the shape of two balance weights 3 can take different shapes structure, although two cave in be separately positioned on end ring 2 back to two end surfaces, but it also differs and adopts completely relative position relationship, two depressions can be arranged on back to both side surface on optional position, and adjust counterweight relation according to actual needs, thus reach the effect of balance.
In addition, in other embodiments of the present utility model, depression also can adopt be opened in two end ring 2 back to end surface and/or and end ring 2 outer surface between structure, the shape of balance weight 3 is mated with concave shape equally.
The thickness of balance weight 3 is no more than the degree of depth of depression, balance weight 3 and end ring 2 are riveted and after imbedding the depression of end ring, the outer surface of balance weight 3 and the end surfaces of end ring 2 substantially in same plane, the end surfaces of end ring 2 refer to two aluminium rings 2 back to end surface; Or the outer surface (being also the end surfaces of outer surface lower than end ring 2 of balance weight 3) in depression of balance weight 3, there will not be balance weight 3 to protrude the situation of depression, and then can not produce flow perturbation.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection range of claims.
Claims (9)
1. a balance weight embedded structure, is arranged on the rotor of motor, and described rotor comprises end ring, it is characterized in that, described balance weight embedded structure also comprises balance weight, and described end ring has depression, and described balance weight to be arranged on described end ring and to imbed described depression.
