Abstract
The utility model discloses the location structure of a kind of refrigerant compressor DC motor stator iron core and rule skeleton, belong to the DC motor technology field of refrigerant compressor.Comprise stator core and rule skeleton, rule skeleton symmetry is installed on the two ends of stator core, stator core comprises yoke portion and a plurality of stator core slot, rule skeleton has skeleton line embedding groove, all stator core slots are single trench structure, and skeleton line embedding groove is placed in stator core slot, are arranged with location notch at the outer wall of stator core, be extended with the keeper corresponding with described location notch at the outer wall of rule skeleton, keeper is placed in location notch.Stator core slot is light (directly) hole, and at the recessed location notch of the outer wall of stator core, and rule skeleton is placed in location notch by keeper, not only define the locate mode that rule skeleton is new, and the yoke portion area of stator core is unlikely and reduces, therefore, electric efficiency obviously increases.
Description
[technical field]
The utility model relates to the location structure of a kind of refrigerant compressor DC motor stator iron core and rule skeleton, belongs to the direct current machine part technical field of refrigerant compressor.
[background technology]
In existing refrigerant compressor direct current machine, stator core has yoke portion and a plurality of stator core slot, and wherein, each stator core slot is all step groove structures of different size grooved; Rule skeleton symmetry is installed on the two ends of stator core, rule skeleton has skeleton line embedding groove, the locating flange suitable with stator core slot is had at the bottom land interruption-forming of skeleton line embedding groove, when rule skeleton is installed on the end of stator core, locating flange is placed in the stator core slot of step groove structure, makes rule skeleton play fixation.
Carefully analyze above-mentioned location structure mode, there is following technical deficiency in discovery of being not difficult: because stator core slot is step groove, the yoke portion area of stator core certainly will be reduced, the refrigerant compressor direct current machine that the stator core of this structure is assembled, its electric efficiency is low.In addition, because rule skeleton needs locating flange, cause that the manufacturing cost of rule skeleton is corresponding to raise up.
[utility model content]
The purpose of this utility model is to provide the location structure of the high refrigerant compressor DC motor stator iron core of a kind of electric efficiency and rule skeleton.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
The location structure of refrigerant compressor DC motor stator iron core and rule skeleton, comprise stator core and rule skeleton, rule skeleton symmetry is installed on the two ends of stator core, described stator core comprises yoke portion and a plurality of stator core slot, described rule skeleton has skeleton line embedding groove, all stator core slots are single trench structure, described skeleton line embedding groove is placed in stator core slot, location notch is arranged with at the outer wall of described stator core, be extended with the keeper corresponding with described location notch at the outer wall of rule skeleton, described keeper is placed in location notch.
As to technique scheme supplement further and perfect, the utility model also comprises following additional technical feature:
Each rule skeleton all has four keepers, and in being spacedly distributed, and these four keepers all depart from the symmetrical center line of rule skeleton, and location notch has four, and the position of location notch is corresponding with the position of described keeper.
After all keepers all depart from the symmetrical center line of rule skeleton, rule skeleton and stator core can be made to realize reliable fixing.
Compared with prior art, the utility model tool has the following advantages and beneficial effect:
Abandon the step groove that prior art stator core slot is all different size grooveds, the substitute is all stator core slots and be single trench structure, and at the recessed location notch of the outer wall of stator core, and rule skeleton is placed in location notch by keeper, not only define the locate mode that rule skeleton is new, and the yoke portion area of stator core is unlikely and reduces, the refrigerant compressor direct current machine that the stator core of this structure is assembled, its electric efficiency obviously increases.Further, because rule skeleton has abandoned locating flange of the prior art, rule skeleton is easy to process, cost is low.
[accompanying drawing explanation]
Be described in further detail with regard to the utility model below in conjunction with accompanying drawing.
Fig. 1 is rule skeleton front view of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the structural representation of stator core of the present utility model.
[embodiment]
Refer to shown in Fig. 1 ~ 4, the location structure of refrigerant compressor DC motor stator iron core and rule skeleton, comprise stator core 1 and rule skeleton 2, rule skeleton 2 symmetry is installed on the two ends of stator core 1, stator core 1 comprises yoke portion 12 and a plurality of stator core slot 11, rule skeleton 2 has skeleton line embedding groove 21, all stator core slots are single trench structure, skeleton line embedding groove 21 is placed in stator core slot 11, location notch 10 is arranged with at the outer wall of stator core 1, the keeper 22 corresponding with described location notch 10 is extended with at the outer wall of rule skeleton 2, described keeper 22 is placed in location notch 10.
At this, it is to be noted that present specification is mentioned: all stator core slots are single trench structure, be be different from the step groove that each stator core slot of prior art is all different size grooveds, namely stator core slot of the present utility model is the light straight groove structure of non-step groove.
Each rule skeleton all has four keepers 22, four keepers 22 are in the outer wall be spacedly distributed in each rule skeleton 2, these four keepers 22 all depart from the symmetrical center line of rule skeleton 2, correspondingly, location notch has four, the position of location notch is corresponding with the position of described keeper, in the outer wall be spacedly distributed in stator core 1.
Two rule skeletons are identical, can generally exchange.
When concrete processing rule skeleton 2, keeper 22 is card base form.
