Detailed Description
Hereinafter, an embodiment of a rotating electrical machine assembling device and a rotating electrical machine assembling method according to the present invention will be described with reference to the drawings.
In the following description, "axial", "circumferential", and "radial" are defined with reference to the axial center of the rotary electric machine.
[ rotating Electrical machine ]
As shown in fig. 1 to 3, the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 of the present embodiment have a common stator unit 20.
The stator unit 20 includes a stator 40 and a stator holder 50. In the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13, a rotor unit (not shown) is rotatably disposed inside the stator 40 of the stator unit 20.
The stator 40 includes a stator core 41 having a substantially annular shape, and a coil 42 mounted on the stator core 41 and configured of a plurality of U-phase, V-phase, and W-phase windings. The stator core 41 is configured by stacking a plurality of substantially annular electromagnetic steel plates 410 in the axial direction. A part of the coil 42 protrudes from end surfaces of both sides in the axial direction of the stator core 41.
The stator holder 50 is disposed around the outer peripheral surface of the stator core 41, and has a substantially cylindrical shape supporting the stator 40. The stator holder 50 is provided with a substantially annular flange portion 52 protruding in the radial direction on one end surface 51 in the axial direction. The flange portion 52 is formed with a plurality of fastening member insertion holes 53 (see fig. 2) penetrating in the axial direction. In the stator holder 50, a cooling medium passage 54 extending in the axial direction is formed inside the stator holder 50.
As shown in fig. 1, the stator unit 20 of the first rotary electric machine 11 is fixed to the first rotary electric machine housing 31.
In the first rotary electric machine 11, the stator unit 20 is fixed to the first rotary electric machine housing 31 by a press-fit, so that the outer peripheral surface of the stator holder 50 is fitted into the first rotary electric machine housing 31. Further, the end surface 52a provided on the axially inner side of the flange portion 52 of the stator holder 50 abuts against the first rotary electric machine housing 31, whereby the stator unit 20 is axially positioned with respect to the first rotary electric machine housing 31.
In the present embodiment, the first rotating electrical machine 11 is configured such that the coolant flows in the coolant passage 54 of the stator holder 50, and is cooled by the coolant flowing in the coolant passage 54 of the stator holder 50.
As shown in fig. 2, the stator unit 20 of the second rotary electric machine 12 is fixed to the second rotary electric machine housing 32.
The end surface 52b provided on the axially outer side of the flange portion 52 of the stator holder 50 abuts against the second rotary casing 32, and the fastening member 60 inserted through the fastening member insertion hole 53 is fastened to the second rotary electric machine casing 32, thereby fixing the second rotary electric machine 12 to the second rotary electric machine casing 32.
Further, a cooling medium passage 321 is formed in the second rotary electric machine housing 32. The cooling medium passage 321 of the second rotary electric machine housing 32 communicates with the cooling medium passage 54 of the stator holder 50.
In the present embodiment, the second rotating electrical machine 12 does not cause the coolant to flow through the coolant passage 321 of the second rotating electrical machine housing 32 and the coolant passage 54 of the stator holder 50, but is cooled by the air flowing through the coolant passage 321 of the second rotating electrical machine housing 32 and the coolant passage 54 of the stator holder 50.
However, since the coolant passage 321 of the second rotating electrical machine housing 32 communicates with the coolant passage 54 of the stator holder 50, when the coolant is supplied to the coolant passage 321 of the second rotating electrical machine housing 32, the coolant is also supplied to the coolant passage 54 of the stator holder 50. In this way, the second rotating electric machine 12 can be easily cooled by liquid.
As shown in fig. 3, the stator unit 20 of the third rotary electric machine 13 is fixed to the third rotary electric machine housing 33.
In the third rotary electric machine 13, the stator unit 20 is fixed to the third rotary electric machine housing 33 by press-fitting, so that the outer peripheral surface of the stator holder 50 is fitted into the third rotary electric machine housing 33. Further, the end surface 52a provided on the axially inner side of the flange portion 52 of the stator holder 50 abuts against the third rotary electric machine housing 33, and the stator unit 20 is axially positioned with respect to the third rotary electric machine housing 33.
In the present embodiment, the third rotary electric machine 13 is configured such that air flows in the cooling medium passage 54 of the stator holder 50, and is cooled by the air flowing in the cooling medium passage 54 of the stator holder 50.
In this way, the first rotary electric machine 11 attaches the stator unit 20 to the first rotary electric machine housing 31 by press fitting, the second rotary electric machine 12 attaches the stator unit 20 to the second rotary electric machine housing 32 by the fastening member 60, and the third rotary electric machine 13 attaches the stator unit 20 to the third rotary electric machine housing 33 by press fitting. Therefore, the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 are different from each other in the mounting form of the stator unit 20 to the rotary electric machine housing.
In the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13, the stator unit 20 is mounted to the rotary electric machine case in a manner of being mounted by press-fitting, by a fastening member, and by press-fitting, respectively, and therefore, the stator unit 20 can be mounted to the rotary electric machine case in a manner of being mounted firmly.
In the present embodiment, the first rotating electrical machine 11 is cooled by the cooling liquid flowing in the cooling medium passage 54 of the stator holder 50, so-called liquid cooling, and the second rotating electrical machine 12 and the third rotating electrical machine 13 are cooled by the air flowing in the cooling medium passage 54 of the stator holder 50, so-called air cooling. Any one of the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 may be cooled by a liquid-cooled, air-cooled, or any other cooling medium.
[ rotating electric machine assembling device ]
As shown in fig. 4, the rotary electric machine assembling apparatus 100 includes: a stator unit assembly line 110 for assembling the stator unit 20; a stator unit mounting line 120 for mounting the stator unit 20 assembled by the stator unit assembly line 110 to any one of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33; a conveyance line 130 connected downstream of the stator unit mounting line 120 and conveying the rotary electric machine housing on which the stator unit 20 is mounted; a rotor unit mounting line 150 connected downstream of the transfer line 130 and mounting the rotor unit in the rotary electric machine housing; and a power transmission device mounting line 160 connected downstream of the rotor unit mounting line 150 and mounting the power transmission device in the rotary electric machine housing.
The stator unit 20 is assembled at the stator unit assembly line 110.
The stator unit mounting line 120 has a main line 121 to be carried into the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33.
The main line 121 is provided with an installation form selecting unit 122. The mounting form selecting section 122 recognizes which one of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is the rotary electric machine housing by the mounting form selecting section 122, and selects a mounting form in which the stator unit 20 is mounted to the rotary electric machine housing from among three mounting forms of mounting by press fitting, and mounting by fastening members.
In the present embodiment, if the rotating electrical machine housing by the mounting form selecting unit 122 is the first rotating electrical machine housing 31, the mounting form selecting unit 122 selects mounting by heat press fitting; if the rotating electrical machine housing passing through the mounting form selecting portion 122 is the second rotating electrical machine housing 32, the mounting form selecting portion 122 selects mounting by a fastening member; if the rotating electrical machine case passing through the mounting form selecting unit 122 is the third rotating electrical machine case 33, the mounting form selecting unit 122 selects to be mounted by press-fitting.
The first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 are respectively marked with two-dimensional codes for identifying which of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is as identification information. The mounting form selecting unit 122 is provided with a two-dimensional code reading device 122A for reading the two-dimensional code marked on the rotary electric machine case.
As shown in fig. 5A and 5B, the two-dimensional code reading device 122A has a reading portion 122B covering the upper side of the main line 121 and both sides in the width direction. In the present embodiment, two reading portions 122B are provided on the upstream side and the downstream side of the main line 121, respectively. A plurality of irradiation portions 122C that emit, for example, red light are provided on the upper side and the two sides in the width direction of the inner side surface of the reading portion 122B. The irradiation unit 122C irradiates red light on both sides in the width direction of the main line 121 on the upper surface of the rotary electric machine case passing through the reading unit 122B of the two-dimensional code reading device 122A. Then, the two-dimensional code reading device 122A reads the two-dimensional code marked on the rotary motor housing passing through the reading portion 122B by an optical sensor (not shown) provided in the reading portion 122B. Then, the mounting form selecting section 122 identifies which of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 the rotary electric machine housing passing through the mounting form selecting section 122 is based on the two-dimensional code read by the two-dimensional code reading device 122A, and selects a mounting form in which the stator unit 20 is mounted to the rotary electric machine housing from among three mounting forms of mounting by press fitting, and mounting by fastening members. In this way, the mounting form selecting section 122 can prevent erroneous selection, and can quickly select one mounting form.
Returning to fig. 4, the stator unit mounting line 120 has a sub-line 123 branched from the main line 121 by a side-out line 191, and the side-out line 191 branches from the main line 121 downstream of the mounting form selection portion 122 of the main line 121. The sub-line 123 merges again with the main line 121 through a side entry line 192 merging with the main line 121.
In the main line 121, a first stator unit carry-in line 111 for carrying in the stator unit 20 assembled in the stator unit assembly line 110 is merged downstream of the side outlet line 191 branched from the main line 121. The main line 121 is provided with a press-fitting device 121A downstream of the junction of the first stator unit carry-in line 111, and a nut runner 121B disposed downstream of the press-fitting device 121A.
The sub-line 123 is provided with a temperature increasing furnace 123A and a thermocompression bonding device 123B disposed downstream of the temperature increasing furnace 123A. In the sub-line 123, a second stator unit carry-in line 112 for carrying in the stator unit 20 assembled in the stator unit assembly line 110 is joined between the temperature increasing furnace 123A and the hot press fitting device 123B. The sub-line 123 merges downstream of the nut runner 121B of the main line 121 through a side inlet line 192 merging with the main line downstream of the temperature increasing furnace 123A.
After the sub-lines 123 meet, the main line 121 is connected to the transfer line 130.
The conveyance line 130 includes an air tightness check necessity determination unit 131. The air-tightness-checking necessity determining portion 131 recognizes which one of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is the rotary electric machine housing passing through the air-tightness-checking necessity determining portion 131, and determines whether or not the air-tightness checking is necessary. In the present embodiment, it is determined that the air tightness check is necessary when the assembled rotating electric machine is liquid-cooled, and it is determined that the air tightness check is not necessary when the assembled rotating electric machine is air-cooled. That is, when the rotary electric machine case passing through the air tightness check necessity determining portion 131 is the first rotary electric machine case 31, it is determined that the air tightness check is necessary, and when the rotary electric machine case passing through the air tightness check necessity determining portion 131 is the second rotary electric machine case 32 or the third rotary electric machine case 33, it is determined that the air tightness check is not necessary.
Downstream of the air-tightness inspection necessity determination portion 131, a side outlet 191 branching from the transfer line 130, an air-tightness inspection line 140 connected to the side outlet 191, and a side inlet 192 merging from the air-tightness inspection line 140 and the transfer line 130 are provided. The airtight inspection line 140 is provided with an airtight inspection device 141.
A rotor unit mounting line 150 is connected downstream of the conveying line 130. The rotor unit mounting line 150 includes a rotor unit/power transmission device selection unit 151. The rotor unit/power transmission device selection unit 151 recognizes which of the first rotary electric machine case 31, the second rotary electric machine case 32, and the third rotary electric machine case 33 is the rotary electric machine case that passes through the rotor unit/power transmission device selection unit 151, and selects a rotor unit to be attached to the rotary electric machine case and gears constituting the power transmission device. The rotor unit mounting line 150 merges with a rotor unit replenishment line 152 for replenishing the rotor unit downstream of the rotor unit/power transmission device selection portion 151.
A power transmission device mounting line 160 for mounting the power transmission device to the rotary electric machine housing is connected downstream of the rotor unit mounting line 150. The power transmission device mounting line 160 merges with a gear type replenishment line 161 for replenishing the gear type constituting the power transmission device.
In the present embodiment, each line of the rotary electric machine assembling apparatus 100 can be rearranged freely, and branching and merging can be performed at an arbitrary position by using the side outgoing line 191 and the side incoming line 192. Accordingly, the rotary electric machine assembling apparatus 100 can assemble rotary electric machines different from any one of the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 by adding or rearranging lines using the side outgoing lines 191 and the side incoming lines 192.
[ rotating Electrical machine Assembly Process ]
Next, a flow of assembling the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 will be described with reference to fig. 6. In fig. 6, for convenience of explanation, the first rotary electric machine housing 31 (first rotary electric machine 11) is denoted by Δ in form, the second rotary electric machine housing 32 (second rotary electric machine 12) is denoted by o in form, and the third rotary electric machine housing 33 (third rotary electric machine 13) is denoted by mouth in form.
First, the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 are mixed and carried into the stator unit mounting line 120. Then, the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 flow on the main line 121, and pass through the mounting style selection unit 122.
If the rotary electric machine case passing through the mounting form selecting unit 122 is the first rotary electric machine case 31, the mounting form selecting unit 122 selects mounting by heat press fitting. Then, the first rotary electric machine housing 31 flows from the main line 121 to the side outlet 191, and is carried to the sub-line 123. The first rotary electric machine housing 31 conveyed to the sub-line 123 is heated in the temperature increasing furnace 123A. Then, in the hot press-fitting device 123B disposed downstream of the temperature increasing furnace 123A, the stator unit 20 carried in from the second stator unit carrying-in line 112 is attached to the first rotating electric machine case 31 heated by the temperature increasing furnace 123A by hot press-fitting. Thereafter, the first rotary electric machine housing 31 to which the stator unit 20 is attached by the press-fit flows on the sub-line 123, is cooled by natural cooling, and is conveyed back from the side inlet line 192 to the main line 121.
If the rotating electrical machine housing passing through the mounting form selecting unit 122 is the second rotating electrical machine housing 32, the mounting form selecting unit 122 selects mounting by a fastening member. Then, the second rotary electric machine housing 32 flows over the main line 121, passes through the press-in device 121A, and is conveyed to the nut runner 121B. In the nut runner 121B, the stator unit 20 carried in from the first stator unit carrying-in line 111 is fastened by the fastening member 60 such as a bolt and is mounted in the second rotary electric machine case 32. The second rotary electric machine housing 32 to which the stator unit 20 is mounted by the fastening member 60 flows on the main line 121.
If the rotating electrical machine case passing through the mounting form selecting unit 122 is the third rotating electrical machine case 33, the mounting form selecting unit 122 selects to be mounted by press-fitting. Then, the third rotary electric machine case 33 flows on the main line 121, and is conveyed to the press-fitting device 121A. In the press-fitting device 121A, the stator unit 20 carried in from the first stator unit carrying-in wire 111 is press-fitted into the third rotary electric machine case 33. The third rotary electric machine housing 33 to which the stator unit 20 is mounted by press-fitting flows on the main wire 121 and passes through the nut runner 121B.
In this way, in the stator unit mounting line 120, the mounting form selecting section 122 selects one mounting form from a plurality of mounting forms, and mounts the stator unit 20 into the rotary electric machine housing in the selected mounting form. Accordingly, the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 are mixed in the stator unit mounting line 120, and the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 having different mounting forms in which the stator unit 20 is mounted to the rotary electric machine housing can be assembled by one stator unit mounting line 120.
In the stator unit 20 that is carried in the stator unit mounting line 120 from the first stator unit carrying-in line 111 and the second stator unit carrying-in line 112, the stator 40 is fixed to the stator holder 50 that includes the cooling medium passage 54. Thereby, the rotary electric machine assembling apparatus 100 can assemble a liquid-cooled rotary electric machine in which the coolant is supplied to the coolant passage 54 of the stator holder 50, and can also assemble a rotary electric machine that requires high cooling performance, corresponding to the rotary electric machine housing to be mounted.
The first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 to which the stator unit 20 is mounted are conveyed from the main line 121 of the stator unit mounting line 120 to the conveying line 130. Then, the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 to which the stator unit 20 is attached flow on the conveyance line 130, and pass through the air tightness check necessity determination unit 131.
If the rotating electric machine case passing through the air-tightness check necessity determining portion 131 is the first rotating electric machine case 31, the air-tightness check necessity determining portion 131 determines that air-tightness check is necessary. Then, the first rotary electric machine case 31 flows from the conveyance line 130 to the side outlet 191, and is conveyed to the airtight inspection line 140. The first rotary electric machine case 31 conveyed to the air tightness inspection line 140 is subjected to air tightness inspection by the air tightness inspection device 141, and it is determined whether or not the coolant does not leak from the first rotary electric machine case 31 to which the stator unit 20 is attached even if the coolant flows through the coolant passage 54 of the stator holder 50. It should be noted that the airtight inspection may be performed by any means. In the air-tightness inspection device 141, it is determined that the cooling liquid does not leak from the first rotating electric machine case 31 to which the stator unit 20 is attached even if the cooling liquid flows through the cooling medium passage 54 of the stator holder 50, flows over the air-tightness inspection line 140, and is conveyed from the side inlet line 192 to the conveying line 130.
If the rotating electric machine case passing through the air-tightness-checking necessity determining portion 131 is the second rotating electric machine case 32 or the third rotating electric machine case 33, the air-tightness-checking necessity determining portion 131 determines that air-tightness checking is not necessary. Then, the second rotary electric machine housing 32 and the third rotary electric machine housing 33 flow through the conveyance line 130 as they are.
In this way, the air tightness check necessity determining portion 131 recognizes the rotary electric machine case passing through the air tightness check necessity determining portion 131, and determines that the air tightness check is necessary when the assembled rotary electric machine is liquid-cooled, and determines that the air tightness check is not necessary when the assembled rotary electric machine is air-cooled. Then, among the rotating electric machine cases to which the stator unit 20 is attached, which are conveyed from the stator unit attaching line 120 to the conveying line 130, only the first rotating electric machine case 31, which needs to be subjected to the air tightness inspection, can be conveyed to the air tightness inspection line 140 to be subjected to the air tightness inspection. That is, the air tightness check may be omitted for the second rotary electric machine case 32 and the third rotary electric machine case 33 that do not require the air tightness check. This enables the air tightness test to be effectively performed.
The first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 to which the stator unit 20 is attached are conveyed from the conveyance line 130 to the rotor unit mounting line 150. Then, the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 to which the stator unit 20 is attached flow on the rotor unit mounting line 150, and pass through the rotor unit/power transmission device selecting section 151.

[ method of assembling rotating Electrical machine ]
Next, an assembling method of the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 will be described with reference to a flowchart shown in fig. 7.
First, a stator unit mounting step of mounting the stator unit 20 to the rotary electric machine housing carried into the rotary electric machine assembly device 100 is performed (step S100).
The stator unit mounting step (step S100) includes a mounting form selecting step (step S110) of selecting a mounting form of mounting the stator unit 20 to the rotary electric machine housing, and a mounting operation step (step S120) of mounting the stator unit 20 to the rotary electric machine housing in the mounting form selected in the mounting form selecting step (step S110). After the mounting form selecting step (step S110), the mounting operation step (step S120) is performed.
The mounting form selecting step (step S110) includes a step S111 of reading a two-dimensional code marked on the rotary electric machine case, a step S112 of determining whether or not the mounting form of the stator unit 20 to the rotary electric machine case is a mounting form by press fitting, and a step S113 of determining whether or not the mounting form of the stator unit 20 to the rotary electric machine case is a mounting form by press fitting.
The mounting operation step (step S120) includes a step S121 of heating the rotary electric machine case, a step S122 of mounting the stator unit 20 to the rotary electric machine case heated in step S121 by press-fitting, a step S123 of cooling the rotary electric machine case to which the stator unit 20 is mounted by press-fitting, a step S124 of mounting the stator unit 20 to the rotary electric machine case by press-fitting, and a step S125 of mounting the stator unit 20 to the rotary electric machine case by the fastening member 60.
In the mounting form selecting step (step S110), first, the two-dimensional code labeled on the rotary electric machine case is read by the two-dimensional code reading device 122A (step S111). In this way, the rotary electric machine housing carried into the rotary electric machine assembly device 100 is identified as being one of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33, and the process proceeds to step S112.
In step S112, it is determined whether or not the stator unit 20 is mounted to the rotary electric machine case by the press-fit. In the case of mounting by the press-fit, the process proceeds to step S121, and in the case of mounting by the press-fit, the process proceeds to step S113. In the present embodiment, when the rotating electrical machine housing carried in the rotating electrical machine assembling device 100 is the first rotating electrical machine housing 31, it is determined that the mounting is performed by the heat press fit, and the process proceeds to step S121; if the rotary electric machine housing carried into the rotary electric machine assembly device 100 is the second rotary electric machine housing 32 or the third rotary electric machine housing 33, it is determined that the mounting is not performed by the press-fit, and the process proceeds to step S113.
In step S113, it is determined whether or not the stator unit 20 is mounted to the rotary electric machine case by press fitting. If the mounting is performed by press fitting, the process proceeds to step S124, and if the mounting is not performed by press fitting, the process proceeds to step S125. In the present embodiment, when the rotating electrical machine housing carried into the rotating electrical machine assembly device 100 is the third rotating electrical machine housing 33, it is determined that the mounting is performed by press fitting, and the process proceeds to step S124; when the rotating electric machine housing carried into the rotating electric machine assembly device 100 is the second rotating electric machine housing 32, it is determined that the mounting is not performed by press fitting, and the process proceeds to step S125.
In this way, in the mounting form selecting step (step S110), which of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is the rotary electric machine housing carried into the rotary electric machine assembly device 100 is identified based on the two-dimensional code read by the two-dimensional code reading device 122A, and the mounting form in which the stator unit 20 is mounted to the rotary electric machine housing is selected from three mounting forms of mounting by press fitting, and mounting by a fastening member. In this way, the mounting form selecting section 122 can prevent erroneous selection, and can quickly select one mounting form.
In step S121, the first rotary electric machine case 31 is heated by the temperature increasing furnace 123A. Then, the process advances to step S122. In step S122, the stator unit 20 is mounted to the first rotary electric machine housing 31 by press-fitting. Then, the process advances to step S123. In step S123, the first rotary electric machine housing 31 to which the stator unit 20 is mounted by the press-fit is cooled. In the present embodiment, the cooling is performed by natural cooling. Then, the process goes to the airtight inspection step (step S200).
In step S124, the stator unit 20 is press-fitted to the third rotary electric machine case 33. Then, the process goes to the airtight inspection step (step S200).
In step S125, the stator unit 20 is fastened to the second rotary electric machine housing 32 by the fastening member 60. Then, the process goes to the airtight inspection step (step S200).
In this way, in the mounting operation step (step S120), the stator unit 20 is mounted in the rotary electric machine case in the mounting form selected in the mounting form selecting step (step S110) from the mounting form selected by press fitting, the mounting by heat press fitting, and the mounting by the fastening member.
Accordingly, the rotary electric machine assembling apparatus 100 can assemble the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13, which are different in the mounting form of the stator unit 20 to the rotary electric machine housing.
In the air tightness inspection step (step S200), air tightness inspection of the rotary electric machine case to which the stator unit 20 is attached is inspected. The air tightness checking step (step S200) includes a step S211 of reading a two-dimensional code marked on the rotary electric machine case, a air tightness checking necessity determining step (step S212) of determining whether or not air tightness checking is necessary for the rotary electric machine case to which the stator unit 20 is attached, an air tightness checking implementation step (step S221) of implementing the air tightness checking, and a defect coping step (step S222).
In step S211, a two-dimensional code marked on the rotary electric machine case is read. The two-dimensional code labeled on the rotary electric machine case can be read by a two-dimensional code reading device similar to the two-dimensional code reading device 122A. In this way, the first rotary electric machine case 31, the second rotary electric machine case 32, and the third rotary electric machine case 33 are identified, and the air tightness check necessity determination step is performed (step S212).
In the air tightness check necessity determination step (step S212), it is determined whether or not an air tightness check is necessary for the rotary electric machine case to which the stator unit 20 is attached. If it is determined that the air tightness test is necessary, the process proceeds to an air tightness test execution step (step S221); if it is determined that the air tightness inspection is not necessary, the process proceeds to a rotor unit/power transmission device selection step (step S300). In the present embodiment, it is determined that the air tightness check is necessary when the assembled rotating electric machine is liquid-cooled, and it is determined that the air tightness check is not necessary when the assembled rotating electric machine is air-cooled. Therefore, when the rotary electric machine case is the first rotary electric machine case 31, it is determined that the air tightness check is necessary, and the process proceeds to the air tightness check implementation step (step S221); if the rotary electric machine case is the second rotary electric machine case 32 or the third rotary electric machine case 33, it is determined that the air tightness check is not necessary, and the process proceeds to the rotor unit/power transmission device selection step (step S300).
In the air-tightness check implementation step (step S221), an air-tightness check is implemented as to whether the coolant does not leak from the first rotating electric machine case 31 to which the stator unit 20 is attached even if the coolant flows through the coolant passage 54 of the stator holder 50. It should be noted that the airtight inspection may be performed by any means. In the air-tightness test execution step (step S221), when it is confirmed that the coolant has not leaked from the first rotary electric machine case 31 to which the stator unit 20 is attached, it is determined that the air-tightness test is acceptable, and the process proceeds to the rotor unit/power transmission device selection step (step S300). In the air-tightness test execution step (step S221), if it is not determined that the air-tightness test is acceptable, the process proceeds to a failure handling step (step S222). In the failure handling step (step S222), the failure of the first rotary electric machine case 31 to which the stator unit 20 is attached is handled, and then the process returns to the air tightness inspection execution step (step S221). Accordingly, the defect handling step (step S222) is repeated until it is determined that the air tightness test is acceptable in the air tightness test execution step (step S221).
In this way, in the rotary electric machine case to which the stator unit 20 is attached, it is possible to perform the air-tightness check only on the first rotary electric machine case 31 that needs to perform the air-tightness check. That is, the air tightness check may be omitted for the second rotary electric machine case 32 and the third rotary electric machine case 33 that do not require the air tightness check. This enables the air tightness test to be effectively performed.
In the rotor unit/power transmission device selection step (step S300), which of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is the rotary electric machine housing is identified, and the rotor unit to be attached to the rotary electric machine housing and gears constituting the power transmission device are selected. The identification of which of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is can be performed by reading by the two-dimensional code reading device similar to the two-dimensional code reading device 122A, or can be performed based on the two-dimensional code read in step S111 and/or step S211. When the rotor unit to be mounted to the rotary electric machine case and the gears constituting the power transmission device are selected in the rotor unit/power transmission device selection step (step S300), the process advances to a rotor unit mounting step (step S400).
In the rotor unit mounting step (step S400), the rotor unit selected in the rotor unit/power transmission device selecting step (step S300) is mounted in the first rotary electric machine case 31, the second rotary electric machine case 32, and the third rotary electric machine case 33. Then, the process advances to a power transmission device mounting process (step S500).
In the power transmission device mounting step (step S500), the gears selected in the rotor unit/power transmission device selecting step (step S300) are mounted in the first rotary electric machine case 31, the second rotary electric machine case 32, and the third rotary electric machine case 33. In this way, the power transmission device is mounted to the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33, and the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 are assembled.
The power transmission device mounting step (step S500) includes a gear assembly step (step S510) and a gear set mounting step (step S520).
In the first gear assembly step (step S510), the gears selected in the rotor unit/power transmission device selection step (step S300) are assembled into a gear set. Then, the gear set mounting process is entered (step S520).
In the gear set mounting step (step S520), the gear set assembled in the gear assembly step (step S510) is mounted in the first rotary electric machine case 31, the second rotary electric machine case 32, and the third rotary electric machine case 33. In this way, the power transmission device is mounted to the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33, and the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 are assembled.
By assembling the rotating electrical machine in this manner, the rotor unit and the power transmission device can be attached to the first rotating electrical machine housing 31, the second rotating electrical machine housing 32, and the third rotating electrical machine housing 33 through a series of processes. The first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13, which are different from each other, can be assembled through a series of steps.
The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and can be modified or improved as appropriate.
For example, in the present embodiment, two-dimensional codes are respectively marked on the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33, and the two-dimensional codes are used as identification information for identifying which one of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is, and the identification information may be any method capable of identifying which one of the first rotary electric machine housing 31, the second rotary electric machine housing 32, and the third rotary electric machine housing 33 is, or may be an external shape of an IC chip or a rotary electric machine housing. In this case, the identification information reading device may use an IC chip reading device or an imaging device in cooperation with the identification information.
For another example, the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 of the present embodiment have a common stator unit 20, but the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13 may have different stator units. For example, in the first rotary electric machine 11, the second rotary electric machine 12, and the third rotary electric machine 13, the lamination thicknesses of the electromagnetic steel plates 410 constituting the stator core 41 may be different from each other.
For another example, in the present embodiment, the identification information is marked on the first rotary electric machine case 31, the second rotary electric machine case 32, and the third rotary electric machine case 33, but the identification information may be marked on the stator unit 20, or may be marked on both the rotary electric machine case and the stator unit 20.
