Description

   The present invention relates to a method for manufacturing a rotor that is a component part of a rotating electrical machine, and more particularly to a method for manufacturing a rotor in which a magnet is integrated with a rotor core.

  As a conventional method for manufacturing a rotor, for example, there is one described in Patent Document 1. In the rotor manufacturing method described in Patent Document 1, a main part of a two-component room temperature curing adhesive and a curing agent are alternately applied in a slot of a rotor core formed by laminating electromagnetic steel sheets, and then a permanent magnet is applied to the slot. It is inserted and buried in the main agent and the curing agent, and the main agent and the curing agent are mixed together with this and the permanent magnet is fixed in the slot.

JP 2011-172347 A

  However, in the conventional rotor manufacturing method as described above, since the main agent and the curing agent are alternately applied in the slots of the rotor core, the curing reaction of the adhesive appears early, and the permanent magnet insertion work is performed. It is necessary to do it promptly. For this reason, there is a high possibility that the rotor being assembled must be discarded after the emergency stop of the production equipment.In addition, by inserting permanent magnets into the main agent and the curing agent applied alternately, It is difficult to say that the mixing of the above is sufficient, and it has been a problem to solve these problems.

  The present invention has been made paying attention to the above-mentioned conventional problems, and is a waste caused by an emergency stop of a production facility so that a curing reaction of a two-component curing type adhesive is started at the final stage of assembly. It aims at providing the manufacturing method of the rotor which can aim at the improvement of the mixability of a 1st liquid and a 2nd liquid, and the improvement of the adhesive strength accompanying this while implement | achieving reduction of rejected goods.

  A rotor manufacturing method according to the present invention includes a rotor core formed by caulking a plurality of laminated rotor steel plates in the laminating direction and fixing them to each other, and a magnet inserted into a slot formed at a predetermined interval in the circumferential direction of the rotor core. A method for manufacturing a rotor. Then, in the rotor steel plate laminating process, the rotor manufacturing method supplies the first and second liquids of the two-component curable adhesive to the same or different layers of the rotor steel plates in an arrangement separated from each other, and into the slots. After inserting the magnet, as the laminated rotor steel plates are pressurized in the laminating direction, the first liquid and the second liquid are allowed to flow into the slot from between the rotor steel sheets, and are mixed. The magnet is fixed in the slot with two liquids.

  In the above-described configuration, in the rotor steel plate laminating step, the first liquid and the second liquid of the two-component curable adhesive may be supplied to the same (same) rotor steel plate in an arrangement separated from each other. By selectively supplying the first liquid and the second liquid to the (individual) rotor steel sheet, the first liquid and the second liquid may be separated from each other via the rotor steel sheet. The first liquid and the second liquid of the two-component curable adhesive are a main agent (or a curing agent) and a curing agent (or a main agent), for example, a two-component room temperature curable adhesive.

  Further, since the rotor steel plates are caulked together in the laminating direction after lamination, in the laminated state, a gap corresponding to a caulking allowance is formed between adjacent rotor steel plates, and the gap is formed in the gap. A first liquid and a second liquid of a two-component curable adhesive are present. For this reason, in the state which laminated | stacked the rotor steel plate, a 1st liquid and a 2nd liquid remain in the supplied position, and do not mutually contact and produce a curing reaction.

  In the rotor manufacturing method according to the present invention, the first liquid and the second liquid of the two-component curable adhesive are supplied to be separated from each other in the same or different layers of the rotor steel plate in the rotor steel plate lamination step. Thus, the first liquid and the second liquid are alternately arranged on the same surface or in the stacking direction, and both of the contacts at the time of pressurization are performed at a number of locations. In addition, in the rotor manufacturing method, after the magnet is inserted into the slot of the rotor core, the first and second liquids of the two-component curable adhesive are mixed as the laminated rotor steel plates are pressed in the laminating direction. As a result, the curing reaction of the two-component curable adhesive is started at the final stage of assembly.

  Thereby, according to the rotor manufacturing method, since the curing reaction of the two-component curable adhesive is not started during the assembly, the reduction of discarded products can be realized even when the manufacturing facility is stopped urgently. In addition, since the first liquid and the second liquid are alternately arranged and contact with each other is performed at a large number of locations, the mixing properties of the first liquid and the second liquid are improved, and accordingly the adhesive strength is improved. Can be achieved.

Two inner slot openings H3 are formed at predetermined intervals (two in total). The two inner slot openings H3 constituting one pole are disposed inclining inward with respect to the center line of the outer slot opening H2.

  In a state where a plurality of rotor steel plates P are stacked, the shaft opening H1 communicates with each other to form a shaft mounting hole SH, and the outer and inner slot openings H2 and H3 communicate with each other to form an outer slot. S1 and inner slot S2 are formed.

  Further, the rotor R shown in FIG. 1 (C) is formed by stacking two rotor cores C shown in FIGS. 1 (A) and 1 (B), providing end plates E1 and E2 on both end faces thereof, and shafts in the shaft mounting holes SH. ST is provided in a penetrating state, and a pair of retainers R1 and R2 that hold both end faces of the rotor core C are press-fitted into the shaft ST.

Next, a method for manufacturing the rotor R will be described with reference to FIGS.
FIGS. 2A to 2C are diagrams illustrating a two-part curable adhesive supply device used in the laminating process of the rotor steel plate P. FIG. The supply device 1 supplies the first liquid, which is the main component of the two-liquid curable adhesive, and the second liquid, which is the curing agent, to the rotor steel plate P disposed on the lamination jig 11. As an example, the adhesive is a two-component room temperature curing type. On the contrary, the first liquid may be a curing agent and the second liquid may be a main agent.

  The supply device 1 includes a lifting body 3 that is movable in the vertical direction with respect to the fixed frame 2, and a first and second body that is movable in the horizontal direction with respect to the lifting body 3 and that has a discharge nozzle at the lower end. Supply guns 4A and 4B are provided, the first liquid is supplied by the first supply gun 4A, and the second liquid is supplied by the second supply gun 4B.

  The stacking jig 11 includes a base 12 that is disposed below the supply device 1 and is driven to rotate about a vertical axis, and a support shaft 13 that is erected at the center of the base 12. The rotor steel plate P is held on the substrate 12 in the stacking jig 11 with the support shaft 13 passing through the shaft opening H1.

  In the method of manufacturing the rotor R, in the lamination process of the rotor steel plates P, the first liquid and the second liquid of the two-component curable adhesive are supplied to the same or different layers of the rotor steel plates P so as to be separated from each other. In this embodiment, in the lamination process of the rotor steel plates P, the supply positions of the first liquid and the second liquid in the lower rotor steel sheet P among the rotor steel sheets P adjacent to each other in the lamination direction, and the upper rotor By relatively different the supply positions of the first liquid and the second liquid on the steel plate P, the first liquid and the second liquid are supplied in an arrangement separated from each other.

  Specifically, as shown in FIG. 2A, after the lowermost rotor steel plate P is set on the laminating jig 11, the first supply gun 4A is moved to the outer peripheral portion of the rotor steel plate P, that is, the outer slot opening. Set to the position near H2. Further, the second supply gun 4B is set between the rotor outer peripheral end and the inner peripheral end of the inner slot opening H3.

  Then, while rotating the rotor steel plate P in one direction together with the laminating jig 11, the first and second supply guns 4A and 4B cause the first liquid F1 indicated by the long broken line and the second liquid F2 indicated by the short broken line to Supply at the same time. At this time, the first and second supply guns 4A and 4B temporarily stop the supply of the first liquid F1 and the second liquid F2 at the positions of the slot openings H2 and H3 of the rotor steel plate P, and the rotor steel plate The first liquid F1 and the second liquid F2 are supplied only on P.

  Thereby, as shown in FIG. 2 (D), the first liquid F1 is supplied to the outer side along the arrangement direction of the outer and inner slot openings H2 and H3 on the rotor steel plate P, and The second liquid F2 is supplied inside. That is, the first liquid F1 and the second liquid F2 are supplied on concentric circles that are separated from each other in the radial direction.

  Thereafter, as shown in FIG. 2B, the next rotor steel plate P is set on the stacking jig 11. At this time, the supply device 1 moves the supply guns 4A and 4B upward and laterally so as not to interfere with the setting of the rotor steel plate P.

  For the next rotor steel plate P, as shown in FIG. 2C, the first supply gun 4A is aligned between the rotor outer peripheral end and the inner peripheral end of the inner slot opening H3, and the second supply gun 4B is matched with the outer peripheral part of the rotor steel plate P, and the 1st liquid F1 and the 2nd liquid F2 are supplied simultaneously. As a result, as shown in FIG. 2E, the second liquid F2 is supplied to the outer side and the first liquid F1 is supplied to the inner side on the rotor steel plate P.

  And the manufacturing method of the rotor R repeats the operation | movement shown to FIG. 2 (A)-(C), and supplies the 1st liquid F1 and the 2nd liquid F2 with lamination | stacking of the rotor steel plate P, and, thereby, a lamination direction 2, the supply positions of the first liquid F1 and the second liquid F2 with respect to the lower-stage rotor steel sheet P shown in FIG. 2D, and the upper-stage rotor steel sheet P shown in FIG. The supply positions of the first liquid F1 and the second liquid F2 are relatively different from each other. Note that, depending on the selected rotor steel plates P, the vertical relationship in FIGS. 2D and 2E may be reversed, but the supply position is relatively different.

  Here, since the rotor steel plates P are caulked together in the laminating direction after lamination, a gap corresponding to a caulking allowance is formed between the adjacent rotor steel plates P in the laminated state. . Specifically, as shown in FIGS. 2A to 2C, the rotor steel plate P has caulking portions K at predetermined intervals along the periphery of the shaft opening H1. This caulking portion K is, for example, irregularities that are reversed in shape, and presses the laminated rotor steel plates P to forcibly fit the irregularities facing each other to fix the rotor steel plates P together. is there.

  For this reason, as shown in FIG. 2C, a gap A is formed by the caulking portion K between the laminated rotor steel plates P, and the first liquid F1 and the second liquid F2 are interposed in the gap A. ing. Therefore, the first liquid F1 and the second liquid F2 stay at the supplied positions and do not come into contact with each other to cause a curing reaction. The first liquid F1 and the second liquid F2 can flow out into the outer and inner slots S1, S2 with the pressurization of the rotor steel plate P, the size of the gap A, the supply position of each other, the slot S1. , S2 and the magnet M, taking into account the volume of the gap, etc., the respective supply amounts are set.

  Next, in the method of manufacturing the rotor R, the rotor steel plates P are laminated as described above to form the rotor core (laminated body before pressurization) C shown in FIG. 3A, and then shown in FIG. 3B. Thus, the magnet M is inserted into each slot S1, S2.

  Thereafter, in the method of manufacturing the rotor R, the first liquid F1 and the second liquid F2 are caused to flow into the slots S1 and S2 from between the rotor steel sheets P as the stacked rotor steel sheets P are pressurized in the stacking direction. The magnet M is fixed in the slots S1 and S2 by the mixed first liquid and second liquid.

  At this time, in order to pressurize the laminated rotor steel plates P in the laminating direction, it is possible to pressurize directly using a pressurizing device (not shown), but in this embodiment, in FIGS. 3 (C) and (D) As shown, a pair of retainers R1 and R2 that hold both end faces of the rotor core C are press-fitted into the shaft ST that is passed through the shaft mounting hole SH, thereby pressing the laminated rotor steel plates P in the laminating direction. It is said.

Are present without contacting each other. When the rotor core C is pressurized in the stacking direction of the rotor steel plates P, the first liquid F1 and the second liquid F2 protrude into the slots S1 and S2 from between the rotor steel plates P as the gap A is compressed. To spill.

  As a result, the first liquid F1 and the second liquid F2 are mixed to generate a mixed liquid F3 that functions as an adhesive, as shown in an enlarged view in FIG. 3D and FIG. The inserted magnet M is fixed in the slots S1 and S2. Thereafter, the rotor R is completed by removing the adhesive protruding outside as required.

  As described above, in the method of manufacturing the rotor R described in the above embodiment, in the laminating process of the rotor steel plate P, the first liquid F1 and the second liquid F1 of the two-component curable adhesive are applied to the same or different layers of the rotor steel plate P. Since the liquid F2 is supplied so as to be spaced apart from each other, the first liquid F1 and the second liquid F2 are alternately disposed on the same surface or in the stacking direction, and both contacts during pressurization are performed at a number of locations.

  Further, in the rotor manufacturing method, after the magnet M is inserted into the slots S1 and S2 of the rotor core C, the first liquid F1 and the second liquid F2 are mixed as the laminated rotor steel plates P are pressurized in the laminating direction. Therefore, the curing reaction of the two-component curable adhesive is started at the final stage of assembly.

  According to the manufacturing method of the rotor R described above, since the curing reaction of the two-component curable adhesive is not started during the assembly of the rotor core C and the magnet M, even if the manufacturing facility is stopped urgently, the discarded product Can be reduced. In addition, since the first liquid F1 and the second liquid F2 are alternately arranged and both contacts at the time of pressurization are performed at many places, the mixing property of the first liquid F1 and the second liquid F2 is improved. Accordingly, the adhesive strength can be improved.

  Moreover, in the method of manufacturing the rotor R described above, the first liquid F1 and the second liquid F2 are supplied by the separate supply guns 4A and 4B, so that the maintenance of the supply device is less than when a two-liquid mixing nozzle is used, for example. Easy.

  Furthermore, in the said embodiment, each supply position of the 1st liquid F1 and the 2nd liquid F2 in the rotor steel plate P of the lower stage among the rotor steel plates P adjacent in the lamination direction, and the 1st in the rotor steel plate P of the upper stage side. The supply positions of the first liquid F1 and the second liquid F2 are relatively different from each other. Thereby, the contact location of the 1st liquid F1 and the 2nd liquid F2 at the time of pressurization increases, and the further improvement of the mixability and adhesive strength of the 1st liquid F1 and the 2nd liquid F2 is realizable.

  Further, in the above embodiment, since the first liquid F1 or the second liquid F2 is supplied along the arrangement direction of the slot openings H2 and H3 of the rotor steel plate P, the first liquid F1 and the second liquid F2 are It becomes easy to flow out into the slot RS, the both are mixed well, and it can also contribute to the saving of the adhesive. Moreover, in the said embodiment, as shown to the enlarged view in FIG.3 (D), since the liquid mixture F3 of the 1st liquid F1 and the 2nd liquid F2 is produced | generated also between rotor steel plates P, liquid mixture F3 Also, the rotor steel plates P are fixed to each other. Thereby, the adhesion strength between the rotor steel plates P is also improved, and the torsional eigenvalue of the rotor R can be improved as a whole.

  Furthermore, in the above-described embodiment, the pair of retainer R1 and R2 that hold both end faces of the rotor core C is press-fitted into the shaft ST that is passed through the shaft attachment hole SH, thereby stacking the rotor steel plates P in the stacking direction. Since pressurization is performed, a dedicated pressurizing step for the rotor core C is not required. That is, since the rotor R in which the retainers R1 and R2 are integrated is completed using an existing assembling apparatus, it is possible to contribute to shortening the manufacturing time and manufacturing cost.

  Furthermore, in the method for manufacturing a rotor according to the present invention, when supplying the first and second liquids of the two-component curable adhesive in the stacking process of the rotor steel plates P, the rotors adjacent to each other in the stacking direction are supplied. It is also possible to supply only the first liquid F1 to the lower rotor steel sheet among the steel sheets P and supply only the second liquid F2 to the upper rotor steel sheet P.

  That is, in the rotor manufacturing method, the first liquid F1 and the second liquid F2 of the two-liquid curable adhesive are supplied to the same (same) rotor steel plate P in the same manner as in the above embodiment. Alternatively, the first liquid F1 and the second liquid F2 are selectively supplied to the rotor steel plate P in different layers (individual) through the rotor steel plate P by selectively supplying the first liquid F1 and the second liquid F2. May be arranged apart from each other. In any case, it is possible to reduce waste products caused by an emergency stop of the production facility, and to improve the mixing property and adhesive strength of the first liquid F1 and the second liquid F2.
