层叠铁芯固定构造1具有利用绝缘体6将非接合状态的层叠钢板2以不会散开的方式固定的构造,因此不需要追加特殊的构件、工序就能够实现具有高磁导率、低铁损的层叠铁芯3的旋转电机的电枢。另外,由于不需要以往使用的层叠钢板2用的焊接、铆钉铆接、粘接等接合手段,能够也享受制造工序的简化、制造成本的减少等效果。需要说明的是,各绕线部5虽然从磁轭4向径向内侧突出,但不限于此,也可以是从磁轭4向径向外侧突出的结构。另外,层叠铁芯3虽然是作为旋转电机的电动机中的作为电枢的定子用的层叠铁芯,但不限于此。The laminated iron core fixing structure 1 has a structure in which the non-joined laminated steel plates 2 are fixed so as not to be scattered by the insulator 6, so it can achieve high magnetic permeability and low iron loss without adding special components or processes. The laminated iron core 3 is the armature of the rotating electric machine. In addition, since joining means such as welding, rivet riveting, and bonding for the conventionally used laminated steel plates 2 are not required, it is possible to enjoy the effects of simplification of the manufacturing process and reduction of manufacturing cost. In addition, although each winding part 5 protrudes radially inward from the yoke 4, it is not limited to this, The structure which protrudes radially outward from the yoke 4 may be sufficient. In addition, although the laminated iron core 3 is a laminated iron core for a stator as an armature in a motor as a rotating electric machine, it is not limited to this.
绝缘体6相对于各绕线部5具有向绕线部5装配的装配部7。各装配部7具有沿着绕线部5的层叠方向两端面延伸的两个端面壁8和在两个端面壁8之间沿着绕线部5的两侧面延伸的两个侧面壁9。因此,通过利用两个端面壁8和两个侧面壁9包围绕线部5,能够将非接合状态的层叠钢板2更可靠地固定。另外,能够确保为了形成电枢而向绝缘体6的装配部7上卷绕的电线等导电体(省略图示)与绕线部5的良好的绝缘。需要说明的是,在图1~图2中,仅对一个装配部7及构成该装配部7的端面壁8及侧面壁9标注标号。需要说明的是,装配部7的结构不限于此。The insulator 6 has a fitting part 7 to be fitted to the winding part 5 with respect to each winding part 5. Each fitting portion 7 has two end surface walls 8 extending along both end surfaces of the winding portion 5 in the stacking direction, and two side walls 9 extending along both side surfaces of the winding portion 5 between the two end surface walls 8. Therefore, by wrapping the surrounding wire portion 5 with the two end face walls 8 and the two side walls 9, it is possible to more reliably fix the laminated steel plate 2 in the non-joined state. In addition, it is possible to ensure good insulation between a conductor (not shown) such as an electric wire wound around the mounting portion 7 of the insulator 6 in order to form an armature and the winding portion 5. It should be noted that, in FIGS. 1 to 2, only one mounting portion 7 and the end wall 8 and side wall 9 constituting the mounting portion 7 are given reference numerals. It should be noted that the structure of the mounting portion 7 is not limited to this.
如图5所示,在各装配部7中,各侧面壁9由经由在绕线部5的 层叠方向上互相卡定的卡定部10而连结的两个分割壁11构成。也就是说,各装配部7由以端面壁8和两个分割壁11构成的两个分割装配部12构成,两个分割装配部12互相经由卡定部10而连结。另外,绝缘体6具有将在周向上排列的全部分割装配部12连结的连结部13。也就是说,绝缘体6由两个分割绝缘体14构成。因此,通过仅利用这些分割绝缘体14将层叠铁芯3夹入的简单的步骤,能够形成如图2所示的整体式的层叠铁芯组装体15。需要说明的是,在图1~图2中省略了卡定部10的图示。卡定部10可以在各侧面壁9遍及整个宽度而连续或断续地设置,也可以在各侧面壁9仅设置于宽度的一部分。需要说明的是,绝缘体6不限于此,例如也可以由两个以上的分割部分构成,还可以不具有连结部13。另外,装配部7的结构也不限于此。As shown in Fig. 5, in each mounting portion 7, each side wall 9 is composed of two divided walls 11 connected via a locking portion 10 that is locked to each other in the stacking direction of the winding portion 5. As shown in FIG. That is, each mounting portion 7 is composed of two divided mounting portions 12 composed of an end surface wall 8 and two divided walls 11, and the two divided mounting portions 12 are connected to each other via the locking portion 10. In addition, the insulator 6 has a connecting portion 13 that connects all the divided assembly portions 12 arranged in the circumferential direction. That is, the insulator 6 is composed of two divided insulators 14. Therefore, it is possible to form a monolithic laminated iron core assembly 15 as shown in FIG. 2 by a simple step of sandwiching the laminated iron core 3 using only these divided insulators 14. It should be noted that the illustration of the locking portion 10 is omitted in FIGS. 1 to 2. The locking portion 10 may be provided on each side wall 9 continuously or intermittently over the entire width, or may be provided on each side wall 9 only in a part of the width. It should be noted that the insulator 6 is not limited to this. For example, it may be composed of two or more divided parts, and the connecting portion 13 may not be provided. In addition, the structure of the mounting portion 7 is not limited to this.
如图1~图2所示,在各装配部7中,从两个端面壁8中的一个8a延伸的分割壁11分别与作为连结对象的分割壁11相比在绕线部5的层叠方向上形成得更短。也就是说,在各装配部7中,两个分割装配部12中的一个12a中的分割壁11分别与作为连结对象的分割壁11相比在绕线部5的层叠方向上形成得更短。因此,在运送层叠铁芯组装体15时,例如,通过支撑各装配部7中的两个分割装配部12中的另一个12b而不是其中的一个12a来运送,能够减少从成为支撑侧的两个分割装配部12中的另一个12b超出的层叠钢板2的量,因此能够减轻该超出的非接合状态的层叠钢板2的一部分伴随运送而通过惯性力、重力等作用于卡定部10的力。因此,能够良好地保持卡定部10的卡定状态,从而良好地保持层叠钢板2的固定状态。需要说明的是,装配部7的结构不限于此。As shown in FIGS. 1 to 2, in each of the mounting portions 7, the dividing wall 11 extending from one 8a of the two end surface walls 8 is in the lamination direction of the winding portion 5 compared to the dividing wall 11 as the connection target. The upper form is shorter. That is, in each of the fitting parts 7, the dividing wall 11 in one 12a of the two dividing fitting parts 12 is formed shorter in the stacking direction of the winding part 5 than the dividing wall 11 as the connection target. . Therefore, when the laminated core assembly 15 is transported, for example, by supporting the other 12b of the two divided assembly parts 12 in each assembly part 7 instead of one of the two parts 12a, it is possible to reduce the number of parts from the supporting side. The other part 12b of the two divided assembly parts 12 exceeds the amount of the laminated steel plate 2, so it is possible to reduce a part of the excess non-joined state of the laminated steel plate 2 that acts on the locking part 10 by inertia force, gravity, etc., accompanying transportation. . Therefore, the locked state of the locking portion 10 can be maintained well, and the fixed state of the laminated steel plate 2 can be maintained well. It should be noted that the structure of the mounting portion 7 is not limited to this.
在各装配部7中,也可以将从两个端面壁8中的一个8a延伸的分割壁11分别以在卡定部10处从远离绕线部5的一侧与作为连结对象的分割壁11重叠的方式构成。根据这样的结构,互相连结的两个分割壁11中的由于更短而更不易产生挠曲变形的一个分割壁11从绕线部5的外侧与另一个分割壁11重叠,因此能够提高卡定部10的卡定力, 更良好地保持层叠钢板2的固定状态。In each mounting portion 7, the dividing wall 11 extending from one 8a of the two end surface walls 8 may be connected to the dividing wall 11 as the object of connection at the locking portion 10 from the side away from the winding portion 5. It is composed in an overlapping manner. According to such a structure, one of the two divided walls 11 connected to each other, which is shorter and less susceptible to flexural deformation, overlaps with the other divided wall 11 from the outside of the winding portion 5, so that the locking can be improved. The locking force of the part 10 maintains the fixed state of the laminated steel plate 2 more satisfactorily.
各侧面壁9具有由互相卡定的卡定部10构成的卡合部16。在各卡合部16中,互相卡定的卡定部10分别由爪17构成。爪17分别由使侧面壁9的厚度朝向前端减小的第一倾斜面18、从第一倾斜面18的前端向厚度方向突出的卡定面19及从卡定面19的突出端起使侧面壁9的厚度朝向前端减小的第二倾斜面20构成。通过这样的结构,能够使卡定部10互相顺滑地卡定。需要说明的是,爪17的结构不限于此。另外,卡合部16不限于由爪17构成。Each side wall 9 has an engaging portion 16 composed of locking portions 10 that are locked to each other. In each of the engaging parts 16, the locking parts 10 that are locked to each other are constituted by claws 17, respectively. The claws 17 are respectively composed of a first inclined surface 18 that reduces the thickness of the side wall 9 toward the front end, a locking surface 19 protruding from the front end of the first inclined surface 18 in the thickness direction, and a side surface from the protruding end of the locking surface 19 The wall 9 is constituted by a second inclined surface 20 whose thickness decreases toward the front end. With such a structure, the locking portions 10 can be smoothly locked to each other. It should be noted that the structure of the claw 17 is not limited to this. In addition, the engaging portion 16 is not limited to being constituted by the claw 17.
需要说明的是,各绕线部5虽然如图1所示那样被设为了具有在径向内侧端处周向宽度扩大的扩大部21的形状,但绕线部5的形状不限于此,例如,各绕线部5也可以是在径向上具有固定的周向宽度的形状。需要说明的是,在图1中,仅对一个扩大部21标注标号。另外,各装配部7虽然具有以使径向内侧端随着绕线部5的扩大部21的方式周向宽度扩大的形状,但装配部7的形状不限于此,能够配合绕线部5的形状而适当变更。It should be noted that although each winding portion 5 has a shape having an enlarged portion 21 having a circumferential width expanded at the radially inner end as shown in FIG. 1, the shape of the winding portion 5 is not limited to this, for example Each winding portion 5 may have a shape having a fixed circumferential width in the radial direction. It should be noted that, in FIG. 1, only one enlarged portion 21 is marked with a reference number. In addition, although each fitting portion 7 has a shape in which the width in the circumferential direction is expanded so that the radially inner end follows the enlarged portion 21 of the winding portion 5, the shape of the fitting portion 7 is not limited to this, and can be fitted to the winding portion 5 Change the shape appropriately.
接着,参照图3~图5,对本发明的第二实施方式的层叠铁芯固定构造进行例示说明。Next, referring to FIGS. 3 to 5, the laminated core fixing structure of the second embodiment of the present invention will be exemplified and described.
如图3~图4所示,本实施方式的层叠铁芯固定构造1具有由非接合状态的层叠钢板2构成的分体式的层叠铁芯3。层叠铁芯3具有分体式的磁轭4和从磁轭4突出的多个也被称作齿、槽等的绕线部5。这样,层叠铁芯3具有由非接合状态的层叠钢板2形成的绕线部5。另外,层叠铁芯固定构造1具有通过向绕线部5装配来固定层叠钢板2的绝缘体6。需要说明的是,在图3~图4中,对与图1~图2所示的构件对应的构件标注有同一标号。绝缘体6例如由合成树脂形成,具有绝缘性。As shown in FIGS. 3 to 4, the laminated iron core fixing structure 1 of the present embodiment has a split laminated iron core 3 composed of laminated steel plates 2 in a non-joined state. The laminated core 3 has a split yoke 4 and a plurality of winding parts 5 that are also called teeth, grooves, etc., protruding from the yoke 4. In this way, the laminated iron core 3 has the winding portion 5 formed of the laminated steel plates 2 in the non-joined state. In addition, the laminated iron core fixing structure 1 has an insulator 6 that fixes the laminated steel plate 2 by fitting to the winding portion 5. It should be noted that, in FIGS. 3 to 4, the same reference numerals are given to members corresponding to the members shown in FIGS. 1 to 2. The insulator 6 is formed of, for example, synthetic resin, and has insulating properties.
层叠铁芯固定构造1具有利用绝缘体6将非接合状态的层叠钢板 2以不会散开的方式固定的构造,因此不需要追加特殊的构件、工序就能够实现具有高磁导率、低铁损的层叠铁芯3的旋转电机的电枢。另外,由于不需要以往使用的层叠钢板2用的焊接、铆钉铆接、粘接等接合手段,能够也享受制造工序的简化、制造成本的减少等效果。需要说明的是,层叠铁芯3虽然是作为旋转电机的电动机中的作为电枢的定子用的层叠铁芯,但不限于此。The laminated iron core fixing structure 1 has a structure in which the non-joined laminated steel plates 2 are fixed so as not to be scattered by the insulator 6, so it can achieve high magnetic permeability and low iron loss without adding special components or processes. The laminated iron core 3 is the armature of the rotating electric machine. In addition, since joining means such as welding, rivet riveting, and bonding for the conventionally used laminated steel plates 2 are not required, it is possible to enjoy the effects of simplification of the manufacturing process and reduction of manufacturing cost. In addition, although the laminated iron core 3 is a laminated iron core for the stator as an armature in the electric motor which is a rotating electrical machine, it is not limited to this.
绝缘体6具有向绕线部5装配的装配部7。需要说明的是,层叠铁芯3虽然具有一个绕线部5,但不限于此,也可以具有两个以上的绕线部5。另外,绝缘体6虽然具有一个装配部7,但不限于此,也可以配合绕线部5的数量而具有两个以上的装配部7。The insulator 6 has a fitting part 7 fitted to the winding part 5. In addition, although the laminated iron core 3 has one winding part 5, it is not limited to this, You may have two or more winding parts 5. In addition, although the insulator 6 has one mounting portion 7, it is not limited to this, and it may have two or more mounting portions 7 according to the number of the winding portions 5.
装配部7具有沿着绕线部5的层叠方向两端面延伸的两个端面壁8和在两个端面壁8之间沿着绕线部5的两侧面延伸的两个侧面壁9。因此,通过利用两个端面壁8和两个侧面壁9包围绕线部5,能够将非接合状态的层叠钢板2更可靠地固定。另外,能够确保为了形成电枢而向绝缘体6的装配部7上卷绕的电线等导电体(省略图示)与绕线部5的良好的绝缘。需要说明的是,装配部7的结构不限于此。The fitting portion 7 has two end surface walls 8 extending along both end surfaces of the winding portion 5 in the stacking direction, and two side walls 9 extending along both side surfaces of the winding portion 5 between the two end surface walls 8. Therefore, by wrapping the surrounding wire portion 5 with the two end face walls 8 and the two side walls 9, it is possible to more reliably fix the laminated steel plate 2 in the non-joined state. In addition, it is possible to ensure good insulation between a conductor (not shown) such as an electric wire wound around the mounting portion 7 of the insulator 6 in order to form an armature and the winding portion 5. It should be noted that the structure of the mounting portion 7 is not limited to this.
如图5所示,各侧面壁9由经由在绕线部5的层叠方向上互相卡定的卡定部10而连结的两个分割壁11构成。也就是说,装配部7由以端面壁8和两个分割壁11构成的两个分割装配部12构成,两个分割装配部12互相经由卡定部10而连结。另外,绝缘体6由两个分割绝缘体14构成。因此,通过利用这些分割绝缘体14将层叠铁芯3夹入的简单的步骤,能够形成如图4所示的分体式的层叠铁芯组装体15。需要说明的是,在图3~图4中,省略了卡定部10的图示。卡定部10可以在各侧面壁9遍及整个宽度而连续或断续地设置,也可以在各侧面壁9仅设置于宽度的一部分。需要说明的是,装配部7的结构不限于此。As shown in FIG. 5, each side wall 9 is composed of two divided walls 11 connected via a locking portion 10 that is locked to each other in the stacking direction of the winding portion 5. That is, the mounting portion 7 is composed of two divided mounting portions 12 constituted by the end face wall 8 and the two divided walls 11, and the two divided mounting portions 12 are connected to each other via the locking portion 10. In addition, the insulator 6 is composed of two divided insulators 14. Therefore, by a simple step of sandwiching the laminated iron core 3 with these divided insulators 14, the split laminated iron core assembly 15 as shown in FIG. 4 can be formed. It should be noted that, in FIGS. 3 to 4, the illustration of the locking portion 10 is omitted. The locking portion 10 may be provided on each side wall 9 continuously or intermittently over the entire width, or may be provided on each side wall 9 only in a part of the width. It should be noted that the structure of the mounting portion 7 is not limited to this.
如图3~图4所示,从两个端面壁8中的一个8a延伸的分割壁11分别与作为连结对象的分割壁11相比在绕线部5的层叠方向上形成得更短。也就是说,两个分割装配部12中的一个12a中的分割壁11分别与作为连结对象的分割壁11相比在绕线部5的层叠方向上形成得更短。因此,在运送层叠铁芯组装体15时,例如,通过支撑两个分割装配部12中的另一个12b而不是其中的一个12a来运送,能够减少从成为支撑侧的两个分割装配部12中的另一个12b超出的层叠钢板2的量,能够减轻该超出的非接合状态的层叠钢板2的一部分伴随运送而通过惯性力、重力等作用于卡定部10的力。因此,能够良好地保持卡定部10的卡定状态,从而良好地保持层叠钢板2的固定状态。需要说明的是,装配部7的结构不限于此。As shown in FIGS. 3 to 4, the dividing wall 11 extending from one 8a of the two end surface walls 8 is formed to be shorter in the stacking direction of the winding portion 5 than the dividing wall 11 to be connected. That is, the dividing wall 11 in one 12a of the two divided mounting parts 12 is formed shorter in the stacking direction of the winding part 5 than the dividing wall 11 as the connection object, respectively. Therefore, when the laminated iron core assembly 15 is transported, for example, by supporting the other 12b of the two divided assembly parts 12 instead of one of the 12a, it is possible to reduce the amount of transmission from the two divided assembly parts 12 serving as the supporting side. By the amount of the laminated steel plate 2 that the other 12b exceeds, it is possible to reduce the force acting on the locking portion 10 by inertial force, gravity, etc., with a part of the laminated steel plate 2 in the non-joined state of the excess. Therefore, the locked state of the locking portion 10 can be maintained well, and the fixed state of the laminated steel plate 2 can be maintained well. It should be noted that the structure of the mounting portion 7 is not limited to this.
也可以将从两个端面壁8中的一个8a延伸的分割壁11分别以在卡定部10处从远离绕线部5的一侧与作为连结对象的分割壁11重叠的方式构成。根据这样的结构,互相连结的两个分割壁11中的由于更短而更不易产生挠曲变形的一个分割壁11从绕线部5的外侧与另一个分割壁11重叠,因此能够提高卡定部10的卡定力,更良好地保持层叠钢板2的固定状态。The dividing wall 11 extending from one 8a of the two end surface walls 8 may be configured so as to overlap the dividing wall 11 as the connection target from the side away from the winding portion 5 at the locking portion 10. According to such a structure, one of the two divided walls 11 connected to each other, which is shorter and less susceptible to flexural deformation, overlaps with the other divided wall 11 from the outside of the winding portion 5, so that the locking can be improved. The locking force of the part 10 maintains the fixed state of the laminated steel plate 2 more satisfactorily.
各侧面壁9具有由互相卡定的卡定部10构成的卡合部16。在各卡合部16中,互相卡定的卡定部10分别由爪17构成。爪17分别由使侧面壁9的厚度朝向前端减小的第一倾斜面18、从第一倾斜面18的前端向厚度方向突出的卡定面19及从卡定面19的突出端起使侧面壁9的厚度朝向前端减小的第二倾斜面20构成。通过这样的结构,能够使卡定部10互相顺滑地卡定。需要说明的是,爪17的结构不限于此。另外,卡合部16不限于由爪17构成。Each side wall 9 has an engaging portion 16 composed of locking portions 10 that are locked to each other. In each of the engaging parts 16, the locking parts 10 that are locked to each other are constituted by claws 17, respectively. The claws 17 are respectively composed of a first inclined surface 18 that reduces the thickness of the side wall 9 toward the front end, a locking surface 19 protruding from the front end of the first inclined surface 18 in the thickness direction, and a side surface from the protruding end of the locking surface 19 The wall 9 is constituted by a second inclined surface 20 whose thickness decreases toward the front end. With such a structure, the locking portions 10 can be smoothly locked to each other. It should be noted that the structure of the claw 17 is not limited to this. In addition, the engaging portion 16 is not limited to being constituted by the claw 17.
需要说明的是,绕线部5虽然如图3所示那样被设为了具有在径向内侧端处周向宽度扩大的扩大部21的形状,但绕线部5的形状不限于此,例如,绕线部5也可以是在径向上具有固定的周向宽度的形状。 需要说明的是,装配部7虽然具有以使径向内侧端随着绕线部5的扩大部21的方式周向宽度扩大的形状,但装配部7的形状不限于此,能够配合绕线部5的形状而适当变更。It should be noted that although the winding portion 5 has a shape having an enlarged portion 21 whose circumferential width is enlarged at the radially inner end as shown in FIG. 3, the shape of the winding portion 5 is not limited to this, for example, The winding part 5 may have a shape having a fixed circumferential width in the radial direction. It should be noted that although the fitting portion 7 has a shape in which the radially inner end follows the enlarged portion 21 of the winding portion 5, the circumferential width is expanded, but the shape of the fitting portion 7 is not limited to this, and can be fitted to the winding portion. The shape of 5 is appropriately changed.
需要说明的是,在前述的第一实施方式及第二实施方式的层叠铁芯固定构造1中,互相连结的两个分割壁11中的更短的一个分割壁11与更长的一个分割壁11的长度之比例如是1:4,但不限于此。另外,在前述的第一实施方式及第二实施方式的层叠铁芯固定构造1中,各侧面壁9的厚度T例如是0.5mm,在该情况下,各卡定面19处的侧面壁9的厚度方向的宽度W例如是0.20~0.25mm。另外,第一实施方式及第二实施方式的层叠铁芯固定构造1以构成空调用电动机的定子的情况为例进行了说明。但是,其用途不限于空调,上述的层叠铁芯固定构造1能够用于构成各种用途、尺寸的电枢。It should be noted that in the laminated core fixing structure 1 of the first and second embodiments described above, the shorter one of the two divided walls 11 and the longer one of the two divided walls 11 connected to each other The length ratio of 11 is, for example, 1:4, but it is not limited to this. In addition, in the laminated iron core fixing structure 1 of the aforementioned first and second embodiments, the thickness T of each side wall 9 is, for example, 0.5 mm. In this case, the side wall 9 at each locking surface 19 The width W in the thickness direction of is, for example, 0.20 to 0.25 mm. In addition, the laminated iron core fixing structure 1 of the first embodiment and the second embodiment has been described by taking a case where a stator of an air-conditioning motor is configured as an example. However, its use is not limited to air conditioners, and the above-mentioned laminated core fixing structure 1 can be used to construct armatures of various uses and sizes.
