Below in conjunction with accompanying drawing and preferred embodiment, its embodiment of stator structure, structure, feature and the effect thereof of the reciprocating motion type electric machine that foundation the present invention is proposed, describe in detail as after.
See also Fig. 4, Fig. 5, shown in Figure 6, Fig. 4 is the schematic diagram of the stator that disassembles on the reciprocating motion type electric machine of the present invention, Fig. 5 is the schematic diagram of the stator core lamination of reciprocating motion type electric machine of the present invention, and Fig. 6 is the front view of the stator on the reciprocating motion type electric machine of the present invention.
As shown in Figure 4, the inside stator of the reciprocating motion type electric machine that proposes according to the present invention comprises: several stator cores are stacked into one group, again with these the fragmentary stator core group 110 that stacks radial formation laminated body, parts that between stator core group 110, becomes laminated body organized, form the iron core group 120 of magnetic circuit, be pressed into the both sides of stator core group 110 and iron core group 120 continuously, keep the retainer ring 130 of the drum of each laminated body to constitute.
Stator core group 110 as shown in Figure 4 and Figure 5, respectively several stator cores 111 are stacked layer by layer, when projection from the side, the inner peripheral surface of formation internal diameter stacks with the curvature depression of appointment, and the outer peripheral face of formation external diameter stacks moulding with the curvature projection identical with above-mentioned inner peripheral surface.
Therefore, form recess 111a at the position, plane of each stator core 111, the projection of above-mentioned recess 111a is pressed in the contiguous recess 111a groove with forcing press forms lamination.
The shape of iron core group 120 is equal to the shape in space between the stator core group 110, and this iron core group 120 stacks with the shape that the inner peripheral surface with stator core group 110 agrees with mutually under normal conditions.Because above-mentioned space forms the cross sectional shape of fan when plane projection, therefore, iron core group 120 is the best the same shape that also forms fan with the space when plane projection.And the described iron core group 120 the most handy materials the same with stator core are made with extrusion process.
In addition, the two sides of stator core group 110 and iron core group 120 form the retainer ring insertion groove 112,121 of ring-type, and described retainer ring 130 is pressed in it.
The manufacture method of the inside stator of the aforesaid reciprocating motion type electric machine of releasing according to the present invention is as follows.
Steel plate produced hundreds of stator core 111 according to designated shape after, several stator cores 111 are stacked form stator core group 110 again.At this moment, form on each stator core 111 in the recess 111a, the recess 111a groove inner-stator iron core 111 that the projection of this recess 111a is pressed into contiguous stator core 111 is combined closely it.
Afterwards, stator core group 110 is formed radiation regimes stack, the corner angle of each stator core group 110 inner peripheral surface are contacted with the corner angle of the inner peripheral surface of the stator core group 110 of vicinity.The density that this not only helps improving iron core also helps and keeps its drum constant.
At last, insert iron core group 120 in the space between each stator core group 110, again the retainer ring 130 of ring-type is pressed in the retainer ring insertion groove 112,121 that the two sides of stator core group 110 and iron core group 120 are provided with, makes stator core group 110 and iron core group 120 keep cylindrical shapes.
Because said method is that the stator core group is stacked, compared with the way that more than of hundreds of stator cores are stacked, it not only can make the operation that stacks of stator core be more prone to finish, and, can enhance productivity by shortening the activity duration.
In addition, iron core group is inserted between the stator core group, can be improved the density of inside stator, thereby can effectively reduce the magnetic saturation phenomenon that inside stator produces.
On the other hand, though above-mentioned preferred embodiment is to be the example explanation with the inside stator,, outer stator also can stack stator core in the same way and form the stator core group, iron core group is inserted in the space between the stator core group to form again.
The technological innovation of the stator structure of the reciprocating motion type electric machine of the present invention that above-mentioned structure like this constituted all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every technical solution of the present invention content that do not break away from,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
