Abstract
The utility model discloses the location structure of a kind of refrigerant compressor DC motor stator iron core and insulating support, it comprises stator core and insulating support, insulating support symmetry is installed on the two ends of stator core, stator core comprises yoke portion and a plurality of stator core slot, and stator core at least symmetrically offers a pair installing hole, insulating support has line embedding groove, all stator core slots are single grooved, stator core at least symmetrically offers a pair location hole near described installing hole, insulating support is symmetrically provided with the alignment pin cooperatively interacted with described location hole, line embedding groove is placed in stator core slot, and described alignment pin is inserted in location hole.The utility model not only defines the new locate mode of insulating support, and due to the area of the stator core slot of the area ratio prior art step groove structure in locating and machining hole little, the yoke portion area of the existing stator core of yoke portion area ratio of the utility model stator core is large, and its electric efficiency is high.
Description
[technical field]
The utility model relates to the location structure of a kind of refrigerant compressor DC motor stator iron core and insulating support, 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; Insulating support symmetry is installed on the two ends of stator core, insulating support has line embedding groove, the locating flange suitable with stator core slot is had at the bottom land interruption-forming of line embedding groove, when insulating support is installed on the end of stator core, locating flange is placed in the stator core slot of step groove structure, makes insulating support 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 insulating support needs locating flange, cause that the manufacturing cost of insulating support 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 insulating support.
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 insulating support, comprise stator core and insulating support, insulating support symmetry is installed on the two ends of stator core, described stator core comprises yoke portion and a plurality of stator core slot, and stator core at least symmetrically offers a pair installing hole, described insulating support has line embedding groove, all stator core slots are single trench structure, stator core at least symmetrically offers a pair location hole near described installing hole, insulating support is symmetrically provided with the alignment pin cooperatively interacted with described location hole, described line embedding groove is placed in stator core slot, and described alignment pin is inserted in location hole.
It is two right that above-mentioned location hole has, and it is two right that above-mentioned alignment pin has.
Because stator core of the present utility model only needs to offer two pairs of location holes, compared with being step groove structure with all stator slots of existing stator core, its yoke portion area of stator core of the present utility model is obviously much bigger.
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 stator core at least symmetrically offers a pair location hole, insulating support is symmetrically provided with corresponding alignment pin, the line embedding groove of insulating support is placed in stator core slot, not only define the locate mode that insulating support is new, and due to the area of the stator core slot of the area ratio prior art step groove structure in locating and machining hole little, therefore the yoke portion area of the yoke portion area ratio prior art stator core of the utility model stator core is large, the refrigerant compressor direct current machine that the stator core of this structure is assembled, its electric efficiency obviously increases.Further, because insulating support has abandoned locating flange of the prior art, the processing cost of insulating support 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 insulating support 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]
Referring to shown in Fig. 1 ~ 4, is preferred embodiment of the present utility model.
The location structure of refrigerant compressor DC motor stator iron core and insulating support, comprise stator core 1 and insulating support 2, insulating support 2 symmetry is installed on the two ends of stator core 1, stator core 1 comprises yoke portion 16 and a plurality of stator core slot 15, and stator core 1 at least symmetrically offers a pair installing hole, insulating support 2 has line embedding groove 20, all stator core slots are single trench structure, stator core 1 at least symmetrically offers a pair location hole near described installing hole, insulating support 2 is symmetrically provided with the alignment pin cooperatively interacted with described location hole, line embedding groove 20 is placed in stator core slot 15, and described alignment pin is inserted in location hole.
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.
Two rule skeletons are identical, can generally exchange.
As shown in Figure 4, it is two right that installing hole in the present embodiment has, i.e. a pair installing hole H1, H3 and another is to installing hole H2, H4, wherein, and installing hole H1 and installing hole H3 Central Symmetry, and installing hole H2 and installing hole H4 Central Symmetry.
It is two right that location hole has, i.e. a pair location hole 11,13 and another is to location hole 12,14.Location hole 11, location hole 13 lay respectively near installing hole H1, installing hole H3, and location hole 11 and location hole 13 Central Symmetry; Location hole 12, location hole 14 lay respectively near installing hole H1, installing hole H3, and location hole 12 and location hole 14 Central Symmetry.
It is two right that alignment pin has, i.e. a pair alignment pin 21,23 and another is to alignment pin 22,24.
