  The present invention relates to an aligned winding jig for winding a winding with high accuracy on a salient pole type rotor in a rotating electrical machine.

Conventionally, in a salient pole type rotor in a rotating electric machine, various devices have been made in order to improve the alignment of windings and improve the cooling performance of the coil.
In the conventional salient pole type rotor or winding structure of salient pole type rotor, the groove jig block is connected and fixed to the shaft hole side wall jig of the electric winding, and the outer peripheral side wall jig is connected and fixed to this groove jig block. Thus, there is an arrangement in which an aligned winding jig is formed, and after the winding is released, the aligned winding jig is removed to form an air path at the coil end (see Patent Document 1).

Also, one aligned winding tool is attached so as to sandwich the coil holding plate, and the other aligned winding tool is attached with a screw. Next, the spacer is inserted into the concave portion of the aligned winding tool from the side surface side and attached. Next, the winding work is performed. After completion, the spacer is removed from the side surface of the aligned winding tool, and the screw is removed. One of the aligned winding tools is one that is pulled up and removed after being brought close to the rotor holding plate side (see Patent Document 2).
Furthermore, there is a type in which a winding guide made of an insulating member is attached to both ends of a magnetic core and a winding is formed around the winding guide to form an air path between the iron core at the coil end and the coil (Patent Document). 3).

Embodiment 1 FIG.
FIG. 1 is a perspective view showing a salient pole type rotor wound by an aligned winding jig according to the first embodiment. FIG. 2 is a perspective view showing a state in which the aligned winding jig according to the first embodiment is attached to a salient pole type rotor. For simplification of explanation, FIG. 2 shows a state in which the aligned winding jig is attached to only one pole and is omitted in the other poles. Is to be attached. Further, the coil is omitted so that the configuration of the aligned winding jig can be understood. In the figure, the rotor 1 has a rotor core 2 and a coil 400. The rotor core 2 is configured to have a symmetrical shape with respect to the rotation shaft 6 and further includes thin plates laminated in the axial direction, and has a plurality of salient poles 3 protruding toward the outer periphery in the radial direction. ing. A salient pole body 4 having a constricted shape is formed at the root portion of the salient pole 3, and an iron core hole 5 is provided on the outer peripheral portion of the salient pole 3 in the direction of the rotation axis 6.

  The coil 400 includes an inner coil 410 and an outer coil 420, and a cooling gap 430 is formed between the inner coil 410 and the outer coil 420 at the axial end of the rotor 1. In FIG. 2, the aligned winding jig according to the first embodiment includes an outer guide 100, an inner guide 200, and a clearance bar 110. The outer guide 100 is provided on the both end surfaces in the axial direction of the rotor core 2 and on the outer peripheral side of the salient pole body 4, and another outer guide 100 attached to the opposite end surface of the same pole by the connecting rod 300. Are connected to each other. The inner guide 200 is provided on both end surfaces in the axial direction of the rotor core 2 and on the inner peripheral side of the salient pole body 4. The gap opening rod 110 is inserted between the outer guide 100 and the inner guide 200 facing each other through the outer guide 100 in the radial direction.

  The coil 400 is formed around the salient pole body portion 4 by winding a coil wire using the gap stick 110 as a winding frame. FIG. 2 shows an example in which four gap bars 110 are attached without winding the coil wire. However, in actual use, only two iron core side gap bars 110a are provided. After the inner coil 410 is wound around the iron core side clearance bar 110a in the attached state, and then the two anti iron core side clearance bars 110b are attached, the periphery of the anti iron core side clearance bar 110b is The outer coil 420 is wound around. As will be described later, the gap 110 for cooling is not lost because the coil wire position is held by the rigidity of the coil wire itself, taping, varnish, etc., even if the gap stick 110 is removed after the end of winding.

  FIG. 3 is a perspective view showing the gap stick 110. When the gap stick 110 forms the chamfered portion 111 serving as a position restricting portion in the axial direction and the rotational direction, the shaft portion 112 that is rotatably engaged with the outer guide 100 and the position is fixed, and the coil 400. It comprises a winding portion 113 around which a coil wire is wound and a tip load receiving portion 114 in contact with the inner guide 200. In FIG. 3, only one chamfered portion 111 is shown, but the same chamfered portion is provided on the back side, and two chamfered portions are provided in total. Only one chamfer may be provided. The shaft portion 112 and the tip load receiving portion 114 are formed in a cylindrical shape that is coaxial with the rotating shaft 115 of the clearance bar. The winding portion 113 is formed in a cylindrical shape that is eccentric with respect to the rotary shaft 115 of the gap stick.

  FIG. 4 is a front view showing the clearance bar as viewed from the direction A in FIG. 3, and shows the positional relationship between the shaft portion 112, the winding portion 113, and the tip load receiving portion 114 of the clearance rod 110. In FIG. 4, the outer peripheral surface 1131 of the winding portion 113 is inside the outer peripheral surface 1121 of the shaft portion 112, and the tip load receiving portion outer peripheral surface 1141 is inside the outer peripheral surface 1131 of the winding portion 113. FIG. 5 is a perspective view showing the outer guide 100. The outer guide 100 includes a plurality of circular bearing portions 120 that are holes penetrating in the radial direction of the rotor 1, a clearance bar fixing portion 130 on the outer periphery side of the rotor of the bearing portion 120, and the rotor core 2. The positioning pin 140 and the connecting hole 150 are provided on the contact surface. The bearing part 120 supports the gap stick 110 in a freely rotatable manner.

  The clearance stick fixing portion 130 is provided with a so-called daruma hole 131, one of which is formed in a circular shape (round hole portion) and the other of which is formed in a rectangular shape (square hole portion). Slide in the circumferential direction. When the gap stick fixing portion 130 slides, the round hole portion 1311 of the round hole 131 overlaps with the bearing portion 120 at a certain position, and the square hole portion 1312 of the round hole 131 overlaps with the bearing portion 120 at another position. FIG. 6 is an enlarged front cross-sectional view showing the positional relationship between the bearing portion 120, the dart hole 131 and the gap stick 110, and shows a cross section at the chamfered portion 111 provided on the gap stick 110. . In FIG. 6A, the bearing portion 120 and the square hole portion 1312 overlap each other, and the chamfered portion 111 is fitted to the square hole portion, so that the rotation of the clearance gap rod 110 is restricted. In FIG. 6B, the bearing portion 120 and the round hole portion 1311 overlap with each other, and the gap opening rod 110 is rotatable. In FIG. 5, the gap stick fixing portion 130 is provided with a guide portion 135 when the gap stick fixing portion 130 slides.

  Thus, at the position where the round hole portion 1311 overlaps with the bearing portion 120, the gap stick 110 can be inserted and removed in the direction of the rotation axis 115 of the gap stick and can be rotated, while the square hole portion 1312 and the bearing portion 120. In the overlapping position, the square hole portion 1312 is fitted with the chamfered portion 111, and the gap opening rod 110 is fixed to prevent rotation and insertion / removal. In other words, the bearing portion 120 provided in the outer guide 100 and the gap stick fixing portion 130 provided with the boring hole 131 allow the gap stick 110 to be rotated and inserted and removed, and the gap stick 110 in the axial direction and the rotation direction. A position fixing mechanism is formed. Note that the rotation and insertion / removal mechanism and the position fixing mechanism of the gap-opening rod 110 are not limited to the structures shown in FIGS. 5 to 7 and may be realized by other structures.

The positioning pin 140 is engaged with the core hole 5 to position the outer guide 100 with respect to the rotor core 2. The connecting hole 150 prevents the outer guide 100 from falling from the rotor core 2 or falling off by fitting the connecting rod 300 and connecting them.
FIG. 7 is a perspective view showing the inner guide 200. The inner guide 200 has a fitting portion 210 that comes into contact with the rotor core 2 and a load support portion 220 provided on the outer peripheral side surface. The fitting portion 210 is fitted to the edge of the rotor core 2 to position the inner guide 200 with respect to the rotor core 2.

  FIG. 8 is a schematic diagram showing a load support portion 220 portion of the inner guide 200 when the gap-staking rod 110 is attached to the aligned winding jig, and corresponds to the portion X in FIG. An arrow B indicates a load direction when the coil wire is tightened. The load support unit 220 supports the gap opening rod 110 in the deflection direction by winding when the coil wire is wound around the gap opening rod 110, but does not restrict the rotation and insertion / removal of the gap opening rod 110.

  Next, the coil winding work using the aligned winding jig will be described. First, the inner guide 200 is attached to the inner peripheral side of the salient pole 3 around which the coil 400 is wound on both end surfaces in the axial direction of the rotor core 2. At this time, the edge shape of the rotor core 2 and the fitting portion 210 of the inner guide 200 are fitted and positioned. Next, the outer guide 100 is attached to the outer peripheral side of the salient pole 3 that winds the coil 400 on both axial end surfaces of the rotor core 2. At this time, the positioning pins 140 of the outer guide 100 are fitted into the iron core holes 5 for positioning. The two outer guides 100 are respectively attached to both end surfaces in the rotation axis direction of the rotor core 2 and are connected to each other by a connecting rod 300.

  The iron core side clearance bar 110 a is inserted into the bearing portion 120 from the outer peripheral side of the outer guide 100. At this time, the clearance stick fixing portion 130 is arranged so that the positions of the round hole portion 1311 of the daruma hole 131 and the bearing portion 120 overlap with each other, and the core clearance clearance rod 110a is rotatable and insertable / removable. Yes (see FIG. 6B). After the posture of the gap stick 110 in the rotational direction is adjusted to a predetermined position, the gap stick fixing portion 130 is slid in the circumferential direction, and the square hole portion 1312 of the gap stick fixing portion 130 and the chamfer portion 111 of the gap stick. (See FIG. 6A). Thereby, the iron core side clearance opening rod 110a is fixed and cannot be freely rotated and inserted / removed.

  In this state, coil winding work is performed. After winding the coil wire around the salient pole body 4 a predetermined number of times via the iron core side gap bar 110a, the anti-iron side gap bar 110b is mounted in the same manner as the iron side gap bar 110a, and is arranged in the upper stage. The coil wire is wound around the salient pole body 4 through the anti-iron core side gap opening rod 110b a predetermined number of times. After the coil winding operation is completed, the gap fixing rod fixing portion 130 of the outer guide 100 is slid and arranged so that the round hole portion 1311 of the dart hole 131 overlaps the bearing portion 120 of the outer guide 100 (see FIG. 6B). ). As a result, the gap stick 110 becomes rotatable and insertable / removable.

  FIG. 9 is a schematic diagram showing the state of each gap-opening bar 110 during winding and when released from winding after winding. In FIG. 9, the dotted line indicates the time of winding, and the solid line indicates the time of release. For the sake of easy understanding, the eccentric amount of the clearance gap bar is shown enlarged. The gap-removing rod 110 that has become rotatable rotates around the rotation shaft 115 of the gap-removing rod, and the winding portion 113 moves to the inside of the wound coil 400 (solid line in FIG. 9). As a result, the winding load applied by the coil 400 applied to the gap stick 110 is released, and the gap stick 110 can be easily extracted. Even if the gap stick 110 is in the released state, the outer peripheral surface 1131 of the winding portion 113 is inside the outer peripheral surface 1121 of the shaft portion 112, and the tip load receiving portion outer peripheral surface 1141 is the outer peripheral surface of the winding portion 113. Since it is inside 1131, the gap stick 110 can be pulled straight in the direction of the rotation axis 115 of the gap stick and can be removed without interfering with the coil 400. Thereafter, the outer guide 100 and the inner guide 200 are removed, and the coil winding work is completed. Even if the gap stick 110 is removed after the winding, the cooling gap 430 is not lost because the position of the coil wire is maintained by the rigidity, taping and varnish of the coil wire itself.

  According to such a configuration, the winding of the coil 400 is released by the rotational movement of the gap stick 110, so that the load can be released simultaneously and evenly from the inner peripheral side to the outer peripheral side of the coil 400. it can. For this reason, the posture of the clearance gap rod 110 in the middle of the release work from the winding is tilted, and there is no unbalance due to the load applied when the load is released for each coil wire, and the coil 400 is kept in an aligned state. It can be released from tightening. Further, the gap stick 110 performs the insertion / removal operation from the outer peripheral side, and the rotation and insertion / removal fixing and releasing operations from the outer peripheral side which is the open side. This eliminates the need for work on the inner circumference side of the coil at the back position, improving workability.

  Further, the outer guide 100 is positioned with respect to the rotor core 2 by the positioning pins 140, and the outer guides 100 are fixed to the rotor core 2 by connecting the outer guides 100 to each other by the connecting rod 300. The position and posture can be correctly maintained without falling off or falling down. As a result, the posture of the gap stick 110 attached to the outer guide 100 can be correctly maintained, and the winding alignment can be improved.

  Moreover, since the load support part 220 can support the force by the bending of the gap stick 110, the inner guide 200 can reduce the load applied to the gap stick 110. As a result, the required strength of the gap stick 110 can be reduced and the size can be reduced, so that the gap formed between the coils can be minimized, and the size of the rotating electrical machine in the direction of the rotating shaft 6 can be reduced. can do. In addition, the outer peripheral surface 1131 of the winding portion 113 of the gap stick 110 is inside the outer peripheral surface 1121 of the shaft portion 112, and the tip load receiving portion outer peripheral surface 1141 is inside the outer peripheral surface 1131 of the winding portion 113. Therefore, the gap stick 110 can be drawn straight out from the outer peripheral side of the rotor 1 and can be removed without interfering with the coil 400.

  Thereby, a complicated operation | work is not required, but the clearance gap rod 110 can be removed and workability | operativity improves. Furthermore, the risk of damaging the coil 400 during the removal work can be reduced, and the reliability of the product can be improved. Further, as described above, a plurality of gaps can be easily provided at the time of forming the coil 400 by providing a plurality of clearance gaps 110 and their mounting structures in the direction of the rotation axis 6. Thereby, the cooling performance can be further improved.

The rotation fixing portion 160, the insertion / extraction fixing portion 170 that fixes the clearance gap rod 250 in the direction of the rotation axis 115 of the clearance clearance rod, and the connection hole 150 connected to the connection rod 300 are provided. The bearing part 120 supports the shaft part 112 of the clearance gap rod 250 so as to be rotatable and insertable / removable. The rotation fixing portion 160 has a cam groove 161 that fits with the cam portion 1162.
