なお、ここでは、一例として、図6,図7に示される組付治具70を用いる例について説明する。この組付治具70は、上述のステータ18、振動吸収部材26、センターピース24を組み付けるためのものであり、ベース板72と、スライド機構74と、保持部材76と、切断機構78とを備えている。   Here, as an example, an example using the assembly jig 70 shown in FIGS. 6 and 7 will be described. The assembling jig 70 is for assembling the stator 18, the vibration absorbing member 26, and the center piece 24, and includes a base plate 72, a slide mechanism 74, a holding member 76, and a cutting mechanism 78. ing.

And is configured.

保持部材76は、環状に構成されており、スライド板80の上に固定されている。また、切断機構78は、複数(ここでは、一例として3個)の刃84と、この刃84を保持するホルダ86と、刃84の下側に配置された載置部材88とを有して構成されている。   The holding member 76 has an annular shape and is fixed on the slide plate 80. The cutting mechanism 78 includes a plurality of (here, three as an example) blades 84, a holder 86 that holds the blades 84, and a placement member 88 that is disposed below the blades 84.

この切断機構78は、保持部材76の径方向内側、及び、スライド板80に形成された孔部90にそれぞれ挿通されており、スライド板80の上下動に伴って、このスライド板80及び保持部材76と上下方向に相対移動されるようになっている。また、載置部材88は、上側に凸を成す凸面によって構成された載置面88Aと、この載置面88Aの径方向外側に環状に形成されたストッパ面88Bとを有して構成されている。   The cutting mechanism 78 is inserted through the inside of the holding member 76 in the radial direction and through the hole 90 formed in the slide plate 80. As the slide plate 80 moves up and down, the slide plate 80 and the holding member are inserted. 76 is moved relative to the vertical direction. Further, the mounting member 88 includes a mounting surface 88A formed by a convex surface projecting upward, and a stopper surface 88B formed in an annular shape on the radially outer side of the mounting surface 88A. Yes.

そして、この組付治具70を用いたステータ18、振動吸収部材26、センターピース24の組み付け方法は、次の通りである。   A method for assembling the stator 18, the vibration absorbing member 26, and the center piece 24 using the assembling jig 70 is as follows.

すなわち、先ず、図8に示されるように、振動吸収部材26を成形後の状態で載置部材88の上に載置する。このとき、刃84が連結部66と上下方向に対向するように、振動吸収部材26を切断機構78に対して周方向に位置決めする。なお、この状態では、刃84は、連結部66と離間されている。   That is, first, as shown in FIG. 8, the vibration absorbing member 26 is placed on the placing member 88 in a state after molding. At this time, the vibration absorbing member 26 is positioned in the circumferential direction with respect to the cutting mechanism 78 so that the blade 84 faces the connecting portion 66 in the vertical direction. In this state, the blade 84 is separated from the connecting portion 66.

そして、図9に示されるように、保持部材76を切断機構78に対する上側に位置させた状態で、この保持部材76にステータ18を保持させる。このとき、ステータコア28に形成された第一係合部54の先端凸部54Bと、振動吸収部材26に形成された第一被係合部62の凹部本体62Aとが整合するように、ステータ18を保持部材76に対して周方向に位置決めする。なお、図9では、図示を省略しているが、ステータコア28の各ティース部28Aには、上述のステータコイル30(図1参照)を予め巻回させてステータ18を完成させた状態とする。   Then, as shown in FIG. 9, the stator 18 is held by the holding member 76 in a state where the holding member 76 is positioned above the cutting mechanism 78. At this time, the stator 18 is aligned such that the tip convex portion 54B of the first engaging portion 54 formed on the stator core 28 and the concave main body 62A of the first engaged portion 62 formed on the vibration absorbing member 26 are aligned. Is positioned in the circumferential direction with respect to the holding member 76. Although not shown in FIG. 9, the stator coil 30 is completed by previously winding the stator coil 30 (see FIG. 1) around each tooth portion 28 </ b> A of the stator core 28.

続いて、図10,図11に示されるように、保持部材76(図9参照)と共にステータ18を下降させて、ステータ18の径方向内側に振動吸収部材26を挿入する。また、このようにすると、各振動吸収ピース60が凸面とされた載置部材88の載置面88Aによって下側から支持された状態で、先端凸部54Bが凹部62Bの開口周辺部と接触する。そして、これにより、各振動吸収ピース60の外周部60Aが振動吸収部材26の軸方向一方側(矢印Z1側)から径方向外側(矢印R1側)を向くように、複数の振動吸収ピース60が複数の連結部66を支点として回動させられる。   Subsequently, as shown in FIGS. 10 and 11, the stator 18 is lowered together with the holding member 76 (see FIG. 9), and the vibration absorbing member 26 is inserted inside the stator 18 in the radial direction. Further, in this manner, the tip convex portion 54B comes into contact with the peripheral portion of the opening of the concave portion 62B in a state where each vibration absorbing piece 60 is supported from the lower side by the mounting surface 88A of the mounting member 88 having a convex surface. . As a result, the plurality of vibration absorbing pieces 60 are arranged such that the outer peripheral portion 60A of each vibration absorbing piece 60 faces the radially outer side (arrow R1 side) from one axial side (arrow Z1 side) of the vibration absorbing member 26. The plurality of connecting portions 66 can be turned as fulcrums.

また、このときには、複数の振動吸収ピース60の回動に伴って、連結部66が長手方向に引っ張られて伸長され、この連結部66に刃84が徐々に接近する。   At this time, as the plurality of vibration absorbing pieces 60 rotate, the connecting portion 66 is pulled and elongated in the longitudinal direction, and the blade 84 gradually approaches the connecting portion 66.

そして、図12に示されるように、保持部材76(図9参照)と共にステータ18がさらに下降されると、各振動吸収ピース60の外周部60Aが振動吸収部材26の径方向外側を向くように、各振動吸収ピース60が90度回動された状態となる。   Then, as shown in FIG. 12, when the stator 18 is further lowered together with the holding member 76 (see FIG. 9), the outer peripheral portion 60 </ b> A of each vibration absorbing piece 60 faces the radially outer side of the vibration absorbing member 26. Each vibration absorbing piece 60 is turned 90 degrees.

なお、このとき、載置面88Aの外径は、各振動吸収ピース60の内周部60Bの内径よりも大径に設定されており、これにより、載置面88Aと各振動吸収ピース60との干渉が抑制される。また、各振動吸収ピース60が載置部材88のストッパ面88Bと当接されることにより、保持部材76及びステータ18の下降が規制される。   At this time, the outer diameter of the mounting surface 88A is set to be larger than the inner diameter of the inner peripheral portion 60B of each vibration absorbing piece 60, whereby the mounting surface 88A and each vibration absorbing piece 60 Interference is suppressed. Further, when each vibration absorbing piece 60 comes into contact with the stopper surface 88B of the mounting member 88, the lowering of the holding member 76 and the stator 18 is restricted.

そして、このようにして各振動吸収ピース60が90度回動された状態となると、第一係合部54と第一被係合部62、すなわち、凸部本体54Aと凹部本体62A、先端凸部54Bと凹部62B、突条部54Cと溝部62C(図2〜図5参照)とがそれぞれ係合されて、振動吸収部材26がステータ18に周方向及び軸方向に移動不能に組み付けられる。(以上、第一組付工程)。   When the vibration absorbing pieces 60 are turned 90 degrees in this way, the first engaging portion 54 and the first engaged portion 62, that is, the convex portion main body 54A and the concave portion main body 62A, the tip convex portion The portion 54B and the recessed portion 62B, the protrusion 54C and the groove 62C (see FIGS. 2 to 5) are engaged, and the vibration absorbing member 26 is assembled to the stator 18 so as to be immovable in the circumferential direction and the axial direction. (The above is the first assembly process).

また、上述の如く、振動吸収部材26がステータ18に組み付けられると略同時のタイミングで、複数の振動吸収ピース60の間を刃84が通過し、この刃84によって連結部66が切断される。そして、これにより、振動吸収部材26が複数の振動吸収ピース60に分離される(以上、分離工程)。   As described above, when the vibration absorbing member 26 is assembled to the stator 18, the blade 84 passes between the plurality of vibration absorbing pieces 60 at substantially the same timing, and the connecting portion 66 is cut by the blade 84. As a result, the vibration absorbing member 26 is separated into a plurality of vibration absorbing pieces 60 (the separation step).

なお、第一係合部54と第一被係合部62とが完全に係合されてから(つまり、振動吸収部材26がステータ18に完全に組み付けられてから)、連結部66が刃84によって切断されても良く、また、第一係合部54と第一被係合部62とが完全に係合される前に(つまり、振動吸収部材26がステータ18に完全に組み付けられる前に)、連結部66が刃84によって切断されても良い。このように、第一係合部54と第一被係合部62とが完全に係合される前に、連結部66が刃84によって切断される場合には、この連結部66が刃84によって切断される前の段階までが、本発明における第一組付工程に相当する。   In addition, after the first engaging portion 54 and the first engaged portion 62 are completely engaged (that is, after the vibration absorbing member 26 is completely assembled to the stator 18), the connecting portion 66 becomes the blade 84. And before the first engaging portion 54 and the first engaged portion 62 are completely engaged (that is, before the vibration absorbing member 26 is completely assembled to the stator 18). ), The connecting portion 66 may be cut by the blade 84. As described above, when the connecting portion 66 is cut by the blade 84 before the first engaging portion 54 and the first engaged portion 62 are completely engaged, the connecting portion 66 becomes the blade 84. Up to the stage before cutting is equivalent to the first assembling step in the present invention.

続いて、図13に示されるように、複数の振動吸収ピース60が組み付けられたステータ18を上述の組付治具70(図6参照)から取り外す。   Subsequently, as shown in FIG. 13, the stator 18 on which the plurality of vibration absorbing pieces 60 are assembled is removed from the above-described assembly jig 70 (see FIG. 6).

そして、図2に示されるように、この複数の振動吸収ピース60からなる振動吸収部材26の径方向内側に軸部40を挿入すると共に、第二被係合部64に第二係合部58を係合させて、ステータ18及び振動吸収部材26にセンターピース24を周方向に移動不能に組み付ける(以上、第二組付工程)。   As shown in FIG. 2, the shaft portion 40 is inserted inside the vibration absorbing member 26 including the plurality of vibration absorbing pieces 60 in the radial direction, and the second engaging portion 58 is connected to the second engaged portion 64. And the center piece 24 is assembled to the stator 18 and the vibration absorbing member 26 so as to be immovable in the circumferential direction (the second assembling step).

続いて、このようにして組み付けられたステータ18、振動吸収部材26、センターピース24(つまり、モータ本体16)に、図1に示されるように、モータハウジング12、エンドハウジング14、軸受50,51、回転軸部材22、ロータハウジング32等を一体に組み付けて、ブラシレスモータ10が完成される。   Subsequently, the stator 18, the vibration absorbing member 26, and the center piece 24 (that is, the motor main body 16) assembled in this way are attached to the motor housing 12, the end housing 14, and the bearings 50 and 51 as shown in FIG. 1. The brushless motor 10 is completed by assembling the rotating shaft member 22, the rotor housing 32, and the like integrally.

なお、ここでは、第一係合部54及び第二被係合部64が凸状に形成され、第一被係合部62及び第二係合部58が凹状に形成された場合の組付方法について説明したが、第一係合部54及び第二被係合部64が凹状に形成され、第一被係合部62及び第二係合部58が凸状に形成された場合にも、上記と同様の要領で組み付けることが可能である。   Here, the assembly in the case where the first engaged portion 54 and the second engaged portion 64 are formed in a convex shape, and the first engaged portion 62 and the second engaged portion 58 are formed in a concave shape. Although the method has been described, the first engaging portion 54 and the second engaged portion 64 are formed in a concave shape, and the first engaged portion 62 and the second engaged portion 58 are also formed in a convex shape. It is possible to assemble in the same manner as described above.

次に、本発明の一実施形態の作用及び効果について説明する。   Next, the operation and effect of one embodiment of the present invention will be described.

このブラシレスモータ10の製造方法によれば、振動吸収部材26として、元々、複数の振動吸収ピース60と、この複数の振動吸収ピース60を環状に連結する複数の連結部66とを一体に有するものを用いている。そして、この振動吸収部材26をステータ18に組み付けてから複数の連結部66を切断して、振動吸収部材26を複数の振動吸収ピース60に分離させている。従って、予め分離された複数の振動吸収ピース60を一つずつステータ18に組み付ける場合に比して、組付工数が少なくて済み、また、製造時に取り置き等に要する時間も短くて済むので、コストを低減することができる。   According to the method for manufacturing the brushless motor 10, the vibration absorbing member 26 originally has a plurality of vibration absorbing pieces 60 and a plurality of connecting portions 66 that connect the plurality of vibration absorbing pieces 60 in an annular shape. Is used. Then, after the vibration absorbing member 26 is assembled to the stator 18, the plurality of connecting portions 66 are cut to separate the vibration absorbing member 26 into a plurality of vibration absorbing pieces 60. Accordingly, as compared with the case where a plurality of vibration absorbing pieces 60 separated in advance are assembled to the stator 18 one by one, the number of assembling steps can be reduced, and the time required for storage at the time of manufacturing can be shortened. Can be reduced.

また、第一組付工程において、各振動吸収ピース60の外周部60Aが振動吸収部材26の軸方向一方側(矢印Z1側)から径方向外側(矢印R1側)を向くように、複数の振動吸収ピース60を複数の連結部66を支点として回動させた場合には、各振動吸収ピース60における振動吸収部材26の軸方向一方側を連結する複数の連結部66が引っ張られて伸長された状態となる。従って、その後の分離工程において、この複数の連結部66を容易に切断することができる。   Further, in the first assembling step, a plurality of vibrations are performed so that the outer peripheral portion 60A of each vibration absorbing piece 60 faces the radially outer side (arrow R1 side) from one axial side (arrow Z1 side) of the vibration absorbing member 26. When the absorbing piece 60 is rotated with the plurality of connecting portions 66 as fulcrums, the plurality of connecting portions 66 that connect one side in the axial direction of the vibration absorbing member 26 in each vibration absorbing piece 60 are pulled and extended. It becomes a state. Therefore, in the subsequent separation step, the plurality of connecting portions 66 can be easily cut.

しかも、連結部66は、ブラシレスモータ10の組付後において他の部材と干渉しない位置に設定されているので、この連結部66の切り口の処理を不要にすることができる。   Moreover, since the connecting portion 66 is set at a position where it does not interfere with other members after the brushless motor 10 is assembled, it is possible to eliminate the processing of the cut end of the connecting portion 66.

また、第一組付工程では、各振動吸収ピース60の外周部60Aが振動吸収部材26の軸方向一方側に向いた状態で振動吸収部材26をステータ18に組み付けるが、この振動吸収部材26としては、振動吸収ピース60同士が干渉しないように、元々、各振動吸収ピース60の外周部60Aが予め振動吸収部材26の軸方向一方側に向けられて成形されたものを用いている。従って、複数の振動吸収ピース60をステータ18に同時に組み付けるときでも、振動吸収ピース60同士が干渉することを抑制することができる。   In the first assembly step, the vibration absorbing member 26 is assembled to the stator 18 with the outer peripheral portion 60 </ b> A of each vibration absorbing piece 60 facing one axial direction of the vibration absorbing member 26. In order to prevent the vibration absorbing pieces 60 from interfering with each other, the outer peripheral portion 60A of each vibration absorbing piece 60 is originally formed so as to be directed to one side in the axial direction of the vibration absorbing member 26 in advance. Therefore, even when the plurality of vibration absorbing pieces 60 are assembled to the stator 18 at the same time, it is possible to prevent the vibration absorbing pieces 60 from interfering with each other.

しかも、第一被係合部62を第一係合部54に係合させるには、各振動吸収ピース60の外周部60Aが振動吸収部材26の軸方向一方側から径方向外側を向くように、複数の振動吸収ピース60を複数の連結部66を支点として回動させるだけで良い。従って、第一被係合部62を第一係合部54に係合させる際の作業性が良好であり、振動吸収部材26をステータ18に容易に組み付けることができる。   In addition, in order to engage the first engaged portion 62 with the first engaging portion 54, the outer peripheral portion 60 </ b> A of each vibration absorbing piece 60 faces the radially outer side from one axial direction side of the vibration absorbing member 26. It is only necessary to rotate the plurality of vibration absorbing pieces 60 around the plurality of connecting portions 66 as fulcrums. Therefore, the workability when the first engaged portion 62 is engaged with the first engaging portion 54 is good, and the vibration absorbing member 26 can be easily assembled to the stator 18.

このように、このブラシレスモータ10の製造方法によれば、複数の振動吸収ピース60をステータ18に同時に組み付けることができ、また、複数の振動吸収ピース60をステータ18に組み付けるときには、単体の部品として取り扱うことが可能で、しかも、振動吸収ピース60をステータ18に組み付け易いので、自動組付を実現することができる。   As described above, according to the method of manufacturing the brushless motor 10, a plurality of vibration absorbing pieces 60 can be assembled to the stator 18 at the same time, and when the plurality of vibration absorbing pieces 60 are assembled to the stator 18, Since the vibration absorbing piece 60 can be easily assembled to the stator 18, automatic assembly can be realized.

なお、仮に、各振動吸収ピースの外周部が振動吸収部材の径方向外側を向くように成形された振動吸収部材を用いる場合、この各振動吸収ピースの外周部に凸状の第一被係合部を形成するためには、スライド型を不要にできるが、この各振動吸収ピースの外周部に凹状の第一被係合部を形成するためには、この振動吸収部材の径方向にスライドするスライド型が必要となり、振動吸収部材の製造コストが増加する。   If a vibration absorbing member formed such that the outer peripheral portion of each vibration absorbing piece faces the radially outer side of the vibration absorbing member is used, a convex first engaged portion is formed on the outer peripheral portion of each vibration absorbing piece. In order to form the part, a slide mold can be made unnecessary, but in order to form the concave first engaged part on the outer peripheral part of each vibration absorbing piece, it slides in the radial direction of the vibration absorbing member. A slide mold is required, which increases the manufacturing cost of the vibration absorbing member.

これに対し、このブラシレスモータ10の製造方法によれば、各振動吸収ピース60の外周部60Aに各第一被係合部62が形成されると共に、各振動吸収ピース60の外周部60Aが振動吸収部材26の軸方向一方側を向くように成形された振動吸収部材26を用いるので、第一被係合部62の凹状又は凸状にかかわらず、この振動吸収部材26の成形時に、第一被係合部62を形成するためのスライド型が不要であり、振動吸収部材26の製造コストを低減させることができる。   On the other hand, according to the manufacturing method of the brushless motor 10, each first engaged portion 62 is formed on the outer peripheral portion 60A of each vibration absorbing piece 60, and the outer peripheral portion 60A of each vibration absorbing piece 60 vibrates. Since the vibration absorbing member 26 shaped so as to face one side in the axial direction of the absorbing member 26 is used, regardless of whether the first engaged portion 62 is concave or convex, A slide mold for forming the engaged portion 62 is unnecessary, and the manufacturing cost of the vibration absorbing member 26 can be reduced.

また、振動吸収部材26として、各振動吸収ピース60の外周部60A及び内周部60Bに第一被係合部62及び第二被係合部64がそれぞれ形成されると共に、各振動吸収ピース60の外周部60A及び内周部60Bが振動吸収部材26の軸方向一方側(矢印Z1側)及び他方側(矢印Z2側)にそれぞれ向けられて成形されたものを用いており、この振動吸収部材26については、この振動吸収部材26の軸方向に分割する上下型で成形することができるので、振動吸収部材26の製造コストをより一層低減させることができる。   Further, as the vibration absorbing member 26, a first engaged portion 62 and a second engaged portion 64 are formed on the outer peripheral portion 60 </ b> A and the inner peripheral portion 60 </ b> B of each vibration absorbing piece 60, respectively. The outer peripheral portion 60A and the inner peripheral portion 60B of the vibration absorbing member 26 are formed so as to be directed to one side (arrow Z1 side) and the other side (arrow Z2 side) of the vibration absorbing member 26, respectively. 26 can be formed by the upper and lower molds that are divided in the axial direction of the vibration absorbing member 26, so that the manufacturing cost of the vibration absorbing member 26 can be further reduced.

なお、本実施形態において、組付治具70を用いたステータ18、振動吸収部材26、センターピース24の組付は、自動的に行われると好適であると説明したが、これらの組み付けが組付治具70を用いた手動で行われても良く、また、組付治具70を用いずに手作業で行われても良いことは勿論である。   In the present embodiment, it has been described that the assembly of the stator 18, the vibration absorbing member 26, and the centerpiece 24 using the assembly jig 70 is preferably performed automatically. Of course, it may be performed manually using the attaching jig 70 or may be performed manually without using the attaching jig 70.

以上、本発明の一実施形態について説明したが、本発明は、上記に限定されるものでなく、上記以外にも、その主旨を逸脱しない範囲内において種々変形して実施可能である。   As mentioned above, although one Embodiment of this invention was described, this invention is not limited above, In addition to the above, in the range which does not deviate from the main point, it can implement in various deformation | transformation.
