Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for assembling a motor, and more particularly, to a method for assembling a motor capable of easily inserting a rotor into an insertion opening of a stator.

[0002]

2. Description of the Related Art In recent years, from the viewpoint of environmental protection, a so-called hybrid vehicle equipped with an automotive internal combustion engine that generates driving force by burning gasoline and a motor 10 shown in FIGS. Has been proposed. The motor 10 generates a driving force based on the power generated by the regeneration and the electric power, thereby assisting the output of the automobile internal combustion engine.

[0003] The motor 10 includes a stator 12 and a rotor 16 inserted into a through hole 14 (insertion port) provided in the stator 12. Of these, the rotor 16
Is a cylindrical portion 20 having a bottom surface 18 as shown in FIG.
And a surrounding wall portion 22 surrounding the cylindrical portion 20, and both of the plurality of bridge portions 24 radially extending from the cylindrical portion 20.
Are integrally connected to each other.

[0004] A plurality of permanent magnets 28 are held on the outer peripheral wall of the peripheral wall portion 22 by winding a film 26 made of carbon fiber reinforced plastic. On the other hand, a plurality of electromagnet coils 30 are positioned and fixed on the inner wall of the through hole 14 of the stator 12, and the electromagnet coils 30 and the film 26 are separated from each other at a predetermined interval. In other words, the rotor 16 is loosely fitted in the through hole 14 of the stator 12.

The bottom surface 18 of the cylindrical portion 20 of the rotor 16 (FIG. 1)
3), a large bolt hole (not shown) is provided at a substantially central portion, and a plurality of bolt holes (not shown) are provided near the large bolt hole. The large bolt holes and the bolts 32 passed through the bolt holes are respectively screwed into large bolt holes B1 and bolt holes B2 (see FIG. 12) provided on the tip end surface of a crankshaft CS constituting the internal combustion engine for a vehicle. Are combined. That is, the rotor 16 is connected to the crankshaft CS via the bolt 32, and thus rotates in accordance with the rotation of the crankshaft CS. In short, the rotor 16 is rotatably accommodated in the through hole 14 of the stator 12.

The reference numeral 33 in FIGS. 12 and 13 indicates a screw hole provided in the cylindrical portion 20.

When the rotor 16 rotates, the permanent magnet 28 held on the outer peripheral wall of the circling wall 22 of the rotor 16 integrally rotates. As a result, when an induced voltage is generated in the electromagnet coil 30, the motor 10
Also functions as a generator.

In such a configuration, the stator 12
Are fixed to a cylinder block (not shown) constituting an internal combustion engine for a vehicle. Further, an electric wiring or the like for electrically connecting the stator 12 and a battery (not shown) is joined to the housing 34 of the stator 12.

[0009]

When the above-described motor 10 is incorporated in an internal combustion engine for an automobile, first, the rotor 16 is connected to the crankshaft CS, and then the stator 12 is fixed to the cylinder block.
The operation of joining electric wiring and the like to the housing 34 of the stator 12 becomes difficult. For this reason, first, the stator 12 is fixed to the cylinder block, and then the rotor 16 is fixed.
Is usually inserted into the through hole 14 of the stator 12.

However, in this case, when the rotor 16 is inserted, the permanent magnet 28 may be attached to the electromagnet coil 30 with each other. As the permanent magnet 28, a magnet having a remarkably high magnetic force, for example, a neodymium-iron-boron-based sintered magnet is generally used. Extremely difficult.

When the permanent magnet 28 and the electromagnet coil 30 are attached to each other, the rotor 16 is rotated to align the bolt hole of the cylindrical portion 20 with the bolt hole B2 of the crankshaft CS. It will be difficult. That is, there is caused a problem that it is difficult to connect the rotor 16 to the crankshaft CS. Even after the motor 10 is installed in the internal combustion engine for a vehicle, a remarkably large driving force must be applied to the crankshaft CS in order to rotate the rotor 16 by separating the permanent magnet 28 from the electromagnet coil 30.

Further, when the permanent magnet 28 and the electromagnet coil 30 are strongly joined to each other, an impact is applied to the permanent magnet 28. If the permanent magnet 28 is not as tough as the sintered magnet described above, there is a concern that the permanent magnet 28 may be damaged by this impact. When such a situation occurs, a problem that the performance of the motor 10 is reduced is caused. This is because the magnetic force of the damaged permanent magnet 28 is significantly reduced as compared to before the damage.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is an object of the present invention to provide a motor in which a rotor can be easily loosely fitted into an insertion opening of a stator, so that there is no fear that a permanent magnet is damaged. It is intended to provide an assembling method.

[0014]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a motor assembling a motor by loosely fitting a rotor into an insertion opening of a stator and connecting the rotor to a rotating shaft. A method for positioning and fixing a rotor holding means holding the rotor to the stator, and causing the rotor to move forward toward an insertion opening of the stator under the action of a feed mechanism constituting the rotor holding means. And inserting the rotor into the insertion opening, removing the rotor holding means from the stator, and connecting the rotor to the rotating shaft.

According to the present invention, the rotor is guided to the insertion opening of the stator by the feed mechanism constituting the rotor holding means while being held by the rotor holding means. For this reason, since the displacement of the rotor toward the electromagnet coil side of the stator due to the magnetic force of the permanent magnet is significantly suppressed, it is possible to avoid the permanent magnet and the electromagnet coil from coalescing. Therefore, the rotor can be easily loosely fitted into the insertion opening of the stator. As a result, the positioning of the rotor can be easily performed.

Moreover, since the permanent magnet does not collide with the electromagnet coil, it is possible to prevent the permanent magnet from being damaged.

In this case, it is preferable that the rotor is inserted into the insertion opening of the stator while the side peripheral wall of the rotor is surrounded by a cover member. This is because dust is prevented by the cover member and the rotor is protected from impact.

Further, when the rotor is held by the rotor holding means, it is preferable that the rotor is mounted on the rotor mounting means. Thereby, the work of holding the rotor on the rotor holding means can be performed easily and easily.

A preferred example of the motor is a motor for a hybrid vehicle disposed between an internal combustion engine for a vehicle and a transmission. In this case, the rotating shaft is a crankshaft that constitutes the automotive internal combustion engine.

The remaining clamp mechanism 60b is configured similarly to the clamp mechanism 60a, and
The same components as those of the clamp mechanism 60a are denoted by the same reference numerals, and description thereof will be omitted.

The rotor holding jig 50 thus configured
FIG. 6 shows a rotor mounting jig used when the rotor 16 is held by the above. The rotor mounting jig 200 includes a base 202 and a mounting table 206 which is disposed substantially at the center of the base 202 and has an insertion port 204 provided at the center thereof.
And four legs 20 erected around the mounting table 206.
8a to 208d. Of the legs 208a to 208d, the two legs 208a and 208b arranged near the corner of the base 202 are used to insert the cylindrical projections 68a and 68b of the rotor holding jig 50. Recess 21
0 and 210 are provided respectively.

Next, a method of assembling a motor using the rotor holding jig 50 will be described. In this assembling method, the rotor holding jig 50 holding the rotor 16 is attached to the stator 12.
A first step of positioning and fixing the rotor 16 and the feed mechanism 58 of the rotor holding jig 50 actuate the rotor 16 toward the through hole 14 of the stator 12 to move the rotor 16 forward.
And a third step of removing the rotor holding jig 50 from the stator 12 and connecting the rotor 16 to the crankshaft CS after removing the rotor holding jig 50 from the stator 12.

In the first step, when the rotor 16 is held by the rotor holding jig 50, the rotor mounting jig 2
The rotor 16 is mounted on the mounting table 206 of No. 00. Then, a cylindrical cover member 21 is provided on the side peripheral wall portion of the rotor 16, that is, outside the film 26 holding the permanent magnet 28.
2 engage. The cover member 212 protects the permanent magnet 28 while protecting the permanent magnet 28 from dust.

Next, as shown in FIG. 7, the insertion recesses 210 of the legs 208a, 208b of the rotor mounting jig 200,
The cylindrical projections 68a, 6 of the rotor holding jig 50
8b is inserted. At this time, the prismatic legs 66a and 66b of the rotor holding jig 50 are mounted on the remaining legs 208c and 208d of the rotor mounting jig 200. The collar member 98 and the ball screw 74 pass through a large bolt hole formed in the bottom surface 18 of the cylindrical portion 20 of the rotor 16 and the insertion port 204 of the mounting table 206. Note that the rotor 16 is disposed in the recess 70 of the base 56. That is, the rotor 16
And the base 56 do not abut each other.

In this state, the pins 62a and 62b are rotated. As a result, the external threads 9 of the pins 62a and 62b are
0 and 90 (see FIG. 4) are screwed into female threads in screw holes 33 provided in the cylindrical portion 20 of the rotor 16, and as a result, the rotor 16 is held by the rotor holding jig 50. Therefore, the rotor holding jig 5 is moved from the rotor mounting jig 200 to the rotor holding jig 5.
When 0 is detached, the rotor 16 also detaches from the mounting table 206.

As described above, by mounting the rotor 16 on the rotor mounting jig 200, the rotor 16 can be easily and simply held on the rotor holding jig 50.

On the other hand, a guide bar 84 is screwed into one of the bolt holes B2 of the crankshaft CS (see FIG. 3). Then, after passing one end of the guide bar 84 through the through hole 94 of the extrusion plate 82 and the through hole 78 of the protective cover 76, the rotor holding jig 50 is directed toward the stator 12 while being guided by the guide bar 84. Then, the collar member 98 attached to the tip of the ball screw 74 is inserted into the large bolt hole of the crankshaft CS, and the columnar projections 68a and 68b are inserted into the screw holes 33 of the stator 12. Also, the pedestal 100 of the clamp mechanism 60a, 60b
Is brought into contact with the housing 34 of the stator 12.

Next, the rotor holding jig 50 is positioned and fixed to the housing 34 by clamping the housing 34 between the clamp mechanisms 60a and 60b. In particular,
The swing lever 154 of the operation lever positioning member 138 is pushed down in the X1 and X2 directions in FIG. As a result, the operation lever positioning member 138 swings around the pin 146 as a fulcrum.

Then, the operation lever 104 is pushed down in the Y1 and Y2 directions. That is, the operation lever 104 is swung about the pin 120 (see FIG. 5) as a fulcrum. Accordingly, the clamp shaft 106 moves forward toward the housing 34, and finally, the holding member 108
Abut. Further, the coil spring 132 is compressed between the disk-shaped member 130 and the prismatic cover 128.

After the holding member 108 is brought into contact with the housing 34 in this manner, the swing lever 154 is released. At this time, as described above, the operation lever positioning member 1
Since the first base 140 of the C. 38 is constantly resiliently urged by the coil spring 152, the operation lever positioning member 138 swings around the pin 146 in a direction opposite to the X1 and X2 directions (see FIG. 3). I do. As a result, FIG.
As shown in FIG. 7, the hook portion 136 of the operation lever positioning member 138 is hooked on the hook pin 134, whereby the operation lever 104 is positioned and fixed, and the pressing member 108 presses the housing 34. That is, the housing 34 is provided with the clamp mechanisms 60a, 60b.
After all, the rotor holding jig 50 is
Is fixed.

Next, in a second step, the rotor 16 is inserted into the through hole 14 of the stator 12. That is, the ball screw 74 is rotated by turning the handle 96 in the arrow Z direction in FIG. Following the rotation, the extruding plate 82 moves forward toward the stator 12 while being guided by the guide bar 84, and as shown in FIG.
a, 62b are connected to the rotor holding jig 5
Depart from 0. At this time, the pins 62a and 62b are separated from the through holes 80a and 80b.

In this case, the rotor 16 is
The guide bar 84 is inserted into the through-hole 94 of the extrusion plate 82 via pins 62a and 62b. In other words, the rotor 16 is connected to the guide bar 8.
Therefore, when the rotor 16 is separated from the rotor holding jig 50, the rotor 16 is significantly restrained from being displaced toward the electromagnet coil 30 of the stator 12 by the magnetic force of the permanent magnet 28 when the rotor 16 is separated from the rotor holding jig 50. You.

That is, by suppressing the displacement of the rotor 16 due to the magnetic force of the permanent magnet 28 by the feed mechanism 58, the permanent magnet 28 and the electromagnet coil 30 can be prevented from coalescing. As shown, the rotor 16 can be inserted into the through hole 14 of the stator 12 with the cover member 212 and the electromagnet coil 30 separated from each other at a predetermined interval. Therefore, the permanent magnet 28 does not collide with the electromagnet coil 30. Therefore, the permanent magnet 28 is not damaged.

Further, since the permanent magnet 28 is surrounded by the cover member 212, it is possible to prevent dust from adhering to the permanent magnet 28 and to prevent direct impact.
That is, the dust is prevented by the cover member 212 and the rotor 16 is protected.

Then, in a third step, the rotor holding jig 50 is removed from the housing 34. That is, the swing levers 154 of the clamp mechanisms 60a and 60b are set to X1,
Push down again in the X2 direction (see FIG. 3) to swing each operation lever positioning member 138. By this swinging operation, the hook portion 136 is detached from the hooking pin 134, and the coil spring 132 is extended to elastically urge the disc-shaped member 130. As a result, each clamp shaft 106
Is moved in a direction away from the housing 34 so that each pressing member 108
Separate from. Thereby, the rotor holding jig 50 is released from the housing 34.

Next, the extrusion plate 82 is detached from the rotor 16 by screwing the pins 62a and 62b and detaching them from the screw holes 33. By this separation, the rotor holding jig 50 is also released from the rotor 16. Further, the rotor holding jig 50 is separated from the housing 34 along the guide bar 84, and finally the guide bar 84 is separated from the through holes 78 and 94. Then, the guide bar 84 may be screwed off and removed from the screw hole 33.

Then, if necessary, the rotor 16 is rotated to align the bolt holes in the bottom surface 18 of the cylindrical portion 20 of the rotor 16 with the bolt holes B2 (see FIG. 3) of the crankshaft CS. The rotation operation of the rotor 16 is as follows.
This can be easily performed by gripping the cover member 212.

Finally, the bolts 32 (see FIG. 13) are inserted into the aligned large bolt holes and the large bolt holes B1 and the bolt holes and the bolt holes B2, respectively.
Is screwed to connect the crankshaft CS and the rotor 16 to form the motor 10 as shown in FIG. If the cover member 212 is pulled out from the rotor 16 after this connection, the permanent magnet 28 and the electromagnet coil 30 face each other without being attached to each other.

As described above, according to the present embodiment, when the rotor 16 is inserted into the through hole 14 of the stator 12, the feed mechanism is held while the rotor 16 is held by the pins 62a and 62b of the rotor holding jig 50. Since the guide is provided by 58, the permanent magnet 28 of the rotor 16 can be prevented from being attached to the electromagnet coil 30. Therefore, the alignment of the rotor 16 is facilitated, and the permanent magnet 28 can be prevented from being damaged.

In the above-described embodiment, the motor 10 for a hybrid vehicle disposed between an internal combustion engine for a vehicle and a transmission has been described by way of example. However, the present invention is not particularly limited to this. Needless to say, such a motor may be used.

[0056]

As described above, according to the method of assembling the motor according to the present invention, the rotor held by the rotor holding means is moved to the insertion opening of the stator by the feed mechanism constituting the rotor holding means. I will guide you to. Therefore, displacement of the rotor toward the electromagnet coil side of the stator due to the magnetic force of the permanent magnet is significantly suppressed. Therefore, it is possible to avoid the permanent magnet and the electromagnet coil from being attached to each other, so that the effect that the rotor can be easily loosely fitted into the insertion opening of the stator is achieved. As a result, the positioning of the rotor can be easily performed.

Moreover, in this case, since the permanent magnet does not collide with the electromagnet coil, it is possible to prevent the permanent magnet from being damaged. Therefore, the concern that the performance of the motor is reduced can be eliminated.
