Below, with regard to the summary of the action of execution mode of the present utility model, describe.At first, one side keeps arrangement property simultaneously to be wound around.Now, during being wound around, will be specifically described having produced clearance portion 79(back) stage also in clearance portion 79, be wound around.After having filled clearance portion 79, again simultaneously keep the arrangement property simultaneously to be wound around.Carry out repeatedly so like this action that simultaneously keeps the arrangement property simultaneously to be wound around and the action that clearance portion 79 is wound around.By like this, filled clearance portion 79.Therefore, can prevent from intermediate layer occurring to be wound around and caving in to the winding direction 85 of caving in.Therefore, both prevented under the state of arrangement that can be good in maintenance being wound around heaving, and prevented from again caving in the winding in intermediate layer.The corresponding relation that each Reference numeral and figure are put up with in back describes.

Below, before the action to execution mode of the present utility model is specifically described, the general structure that is first coil winding machine 200 with regard to action subject describes, and then just action is specifically described.As shown in Figure 8, the flier 72 of coil winding machine 200 form by bottom and from bottom upright two roughly U fonts that roughly polygonal body forms roughly, hollow nozzle 71 is installed on a side roughly polygonal body therein.Coil winding machine 200, from nozzle 71 output coilings 70, utilizes pattern 73 to position, and then on stator core 1, is wound around.Pattern section 90 consists of pattern 73, guide 74, cylinder 75 and axle 76 etc., can carry out the motion (hereinafter referred to as fore-and-aft direction) of arrow 78 directions on cylinder 75 axles.In addition, flier 72 can be turned round (hereinafter referred to as direction of rotation) the central shaft of the axle 76 shown in arrow 77 as the rotating shaft direction, also can carry out the motion of fore-and-aft direction.In addition, pattern section 90 forms the position relationship that is positioned at flier 72 inboards.

As shown in Figure 8, coil winding machine 200, by the action of the direction of rotation of flier 72 and the action of fore-and-aft direction, is supplied with by the front end of the nozzle 71 from being arranged on flier 72 coiling 70 come and is wrapped on the 1a of tooth section.The part that distance 81 between adjacent leading section 1a-1 is less than the roughly U font of flier 72 is two roughly distances between polygonal body, and therefore, if flier 72 is attempted to carry out forward stroke towards stator core 1, flier 72 just can not enter the depths of the 1a of tooth section.So, install on flier 72 and state bright pattern 73, even this pattern 73 is to make according to the size that also can advance towards stator core 1 in distance 81 the gap between the leading section 1a-1 adjacent.That is, the length of the shape of the part of pattern 73 is in distance 81.Pattern 73 replaces flier 72 to advance to the depths of leading section 1a-1 towards stator core 1.By like this, even flier 72 advances but can not arrive the depths of the 1a of tooth section towards stator core 1, coil winding machine 200 also can make the coiling 70 of supplying with from nozzle 71 arrive the depths of the 1a of tooth section along the side of pattern 73.Therefore, coil winding machine 200 can be wound around until the depths of the 1a of tooth section.

When flier 72 carries out the action of fore-and-aft direction, the position relationship that flier 72 is mutual with pattern 73, carry out the action of fore-and-aft direction integratedly.In addition, when flier 72 is rotated the action of direction, only flier 72 is rotated.That is, when being wound around, flier 72 is rotated, but pattern 73 is not rotated the motion of direction.

Like this, coil winding machine 200 carries out the action of direction of rotation of flier 72 and pattern 73 and the action of fore-and-aft direction repeatedly, thereby can form the coil 2 of regulation.

In forward stroke among the stroke of the fore-and-aft direction of flier 72, that advance towards stator core 1, the end of leading section 1a-1 and the pattern shown in Fig. 9 become working range between front inlet side 83.On the other hand, in backward travel among the stroke of the fore-and-aft direction of flier 72, that advance towards the opposite direction of stator core 1, until the end of leading section 1a-1 all becomes working range.As forward stroke, until the reason of the front inlet side 83 of pattern, be because insulation division 3 becomes the shape of forward end 1a-1 lateral bend.That is, the iron core back 1b shown in Fig. 3 becomes the shape of curvature bending according to the rules, because insulation division 3 forms with engaging, so also curvature bending according to the rules of insulation division 3.Therefore, once pattern 73 attempts to move to the end of the 1a of tooth section of insulation division 3 sides, pattern 73 will be subject to the interference of insulation division 3.

In addition, the 70 enterable zones of must guaranteeing to wind the line between insulation division 3 and pattern 73.For this reason, as shown in Figure 9, pattern 73 can only move to the front inlet side 83 of pattern.Therefore, coil winding machine 200 can not move to the action of the fore-and-aft direction that carries out flier 72 under the state of end of the 1a of tooth section of insulation division 3 sides and the action of direction of rotation at pattern 73.Its result, wind the line 70 arrival not the end of the 1a of tooth section of insulation division 3 sides, can produce clearance portion 79 as shown in Figure 9.Said clearance portion 79, specifically refer to the space that the coil end face 84 by insulation division 3, the 1a of tooth section, insulation division 3 sides forms.More particularly, said clearance portion 79, refer to 70 the formed space, surface of respectively winding the line by the coil end face 84 of the curved surface of the face side of the curved surface of insulation division 3 forward end 1a-1 lateral bends, the 1a of tooth section and insulation division 3 sides.

At this, utilize curved surface etc. to be illustrated with regard to all parts, but structure is not limited.

And, under the state that has produced clearance portion 79, as shown in Figure 9, wind the line and 70 cave in to the winding direction 85 of caving in.By like this, as shown in figure 10, the coiling 86 after caving in will be positioned at the position near stator core 1.Under this state, the distance 80 of stator core 1 and coiling 70 is extremely short.Therefore, in withstand voltage test etc., insulation breakdown can occur.

Therefore, in execution mode of the present utility model, when clearance portion 79 becomes large, be wound around path from first of prior setting and be wound around path changing to second of relative gap section 79 and be wound around path, make pattern 73 action reciprocal at fore-and-aft direction carry out repeatedly in the stroke till 83De position, inlet side pattern in the position from coil top 82.By like this, to clearance portion 79, append coiling 70.That is, near the coiling 70 be wrapped in the second winding path coil top 82 enters clearance portion 79, fills as illustrated in fig. 11 clearance portion 79.Now, before clearance portion 79 become greater to a certain degree, do not carry out the action of the fore-and-aft direction of pattern 73.That is, coil winding machine 200 before clearance portion 79 become greater to a certain degree, as usual in the first winding path by the action of the fore-and-aft direction of flier 72 simultaneously wound the line 70 the winding of 70 arrangement that simultaneously keeps winding the line.Therefore, can as prior art, in the winding of each layer of generation coil peak section, not cave in.Therefore, in execution mode of the present utility model, 70 the arrangement of can guaranteeing to wind the line, the winding that can prevent each coil 2 is caved in and winding is heaved, thus the winding that can prevent stator winding 400 is caved in and winding is heaved.

In other words, by filling clearance portion 79, can prevent from during winding the line occurring to be wound around and caving in to the cave in direction of direction 85 of winding, and by guaranteeing to wind the line 70 arrangement, the winding that can prevent stator winding 400 is caved in and winding is heaved.

In addition, about the generation position of clearance portion 79, trying will wind the line in advance 70, to be wrapped in the 1a of tooth section upper, by actual measurement, comes prior confirmation where to form wherefrom clearance portion.

In addition, equally also by actual measurement, confirm the position of the coil end face 84 of coil top 82 and insulation division 3 sides.

In addition, because coiling 70 the number of turn is pre-determined, therefore with the coiling wound the line outside 70, do not fill clearance portion 79.That is, the number of turn of the coiling 70 be wound around in common winding path and the total number of turn in the number of turn that is wound around the coiling 70 that path is wound around via clearance portion 70, become the number of turn of the coiling 70 be wrapped on stator core 1.

In addition, wind the line and 70 be equivalent to winding of the present utility model.

In addition, in execution mode of the present utility model, with regard to an example of winding of single layer, be illustrated, but not limited.Can be also that for example two-phase is wound around.
