発明の開示  Disclosure of the invention
発明が解決しょうとする課題  Problems to be solved by the invention
[0003] し力しながら、上述の構成において、コイル収容ケース力も突設した突起部は、コィ ル収容ケースの内側から局所的にプレスすることで表面を突出させて形成されるの で、図 5 (a)に示されるように、コイル収容ケース 6の突起部 6aは、末広がりの円柱形 状に形成されやすい。 [0003] However, in the above-described configuration, the protruding portion that also projects the coil housing case force is formed by locally pressing from the inside of the coil housing case so that the surface protrudes. As shown in FIG. 5 (a), the protrusion 6a of the coil housing case 6 is likely to be formed in a diverging columnar shape.
[0004] このため、図 5 (b)に示されるように、取付板 8の通孔 8aに突起部 6aを挿入すると、 通孔 8aの周縁が突起部の途中に当接するため突起部 6aは基端まで挿入されなくな り、取付板 8は、コイル収容ケース 6の表面力も僅かに浮いた状態で力しめつけられる ことになる。 [0004] For this reason, as shown in FIG. 5 (b), when the protrusion 6a is inserted into the through hole 8a of the mounting plate 8, the periphery of the through hole 8a abuts in the middle of the protrusion. The base plate is not inserted, and the mounting plate 8 is clamped with the surface force of the coil housing case 6 slightly lifted. It will be.
[0005] よって、取付板 8は、コイル収容ケース 6の表面に面接触されず、突起部 6aが形成 された部分で局所的に固定された状態となるので、コイル収容ケースと取付板との接 合強度が十分でなくなり、コイル収容ケース 6が取付板 8に対して相対的に動きやす くなり、コイル収容ケース 6の振動によって力しめ部が破損したり、騒音レベルが低下 しない不都合が生じる。  [0005] Therefore, the mounting plate 8 is not in surface contact with the surface of the coil housing case 6 and is locally fixed at the portion where the projection 6a is formed. Insufficient joint strength makes the coil housing case 6 easier to move relative to the mounting plate 8, causing the inconvenience that the forceps are not damaged or the noise level is not lowered by the vibration of the coil housing case 6. .
[0006] そこで、この発明にお 、ては、電磁クラッチのコイル収容ケースを取付板を介して所 定の取付箇所に固定するにあたり、コイル収容ケースと取付板との接合強度の向上 を図ると共に、コイル収容ケースの振動を低減することが可能な電磁クラッチの固定 構造を提供することを主たる課題として 、る。  [0006] Therefore, in the present invention, when the coil housing case of the electromagnetic clutch is fixed to a predetermined mounting location via the mounting plate, the joint strength between the coil housing case and the mounting plate is improved. An object of the present invention is to provide an electromagnetic clutch fixing structure capable of reducing the vibration of the coil housing case.
課題を解決するための手段  Means for solving the problem
[0007] 上記課題を達成するために、この発明にかかる電磁クラッチの固定構造は、回転自 在に支持されて駆動源力 の回転力によって回転するロータと、回転軸に連結され、 前記ロータの摩擦面に対向配置される摩擦面を備えたァーマチュアと、前記ァーマ チユアの摩擦面を前記ロータの摩擦面に吸着させる励磁コイルと、この励磁コイルを 収容する環状のコイル収容ケースとを備えた電磁クラッチを有し、前記コイル収容ケ 一スを取付板を介して所定の取り付け箇所に固定するように構成された構成におい て、前記コイル収容ケースと前記取付板との間にシートを介在させて接合するように したことを特徴としている。 [0007] In order to achieve the above object, an electromagnetic clutch fixing structure according to the present invention is connected to a rotor that is supported by a rotation itself and rotates by a rotation force of a drive source force, and is connected to a rotation shaft. An electromagnetic comprising an armature having a friction surface disposed opposite to the friction surface, an excitation coil for attracting the friction surface of the armature to the friction surface of the rotor, and an annular coil housing case for housing the excitation coil In a configuration having a clutch and configured to fix the coil housing case to a predetermined mounting position via a mounting plate, a sheet is interposed between the coil housing case and the mounting plate. It is characterized by being joined.
[0008] したがって、コイル収容ケースと取付板との間にシートが挟み込まれるので、コイル 収容ケースと取付板とはシートに密着した状態で取り付けられることになる。このため 、コイル収容ケースと取付板との間に隙間が形成されなくなるため、取付板に対する コイル収容ケースの振動が低減されることになる。  [0008] Accordingly, since the sheet is sandwiched between the coil housing case and the mounting plate, the coil housing case and the mounting plate are attached in close contact with the sheet. For this reason, since no gap is formed between the coil housing case and the mounting plate, the vibration of the coil housing case with respect to the mounting plate is reduced.
[0009] ここで、シートは、コイル収容ケースの前記取付板が対向する部分の全周に亘つて 設けられるものであっても、コイル収容ケースの前記取付板が対向する部分の周方 向に断続的に設けられるものであってもよ 、。  [0009] Here, even if the seat is provided over the entire circumference of the portion of the coil housing case that faces the mounting plate, the sheet is provided in the circumferential direction of the portion of the coil housing case that faces the mounting plate. It may be provided intermittently.
[0010] また、シートは、接着性のある接着シートを用い、励磁コイルをコイル収容ケースに 榭脂で封入する際の熱処理等を利用して、コイル収容ケースと取付板とに接着させ るようにしてもよい。このため、シートの接着力により接合強度が向上し、取付板に対 するコイル収容ケースの振動が低減されることになる。 [0010] Further, the sheet is an adhesive sheet, and is adhered to the coil housing case and the mounting plate using heat treatment or the like when encapsulating the exciting coil in the coil housing case with grease. You may make it do. For this reason, the bonding strength is improved by the adhesive force of the sheet, and the vibration of the coil housing case with respect to the mounting plate is reduced.
[0011] コイル収容ケースと取付板との接合構造としては、コイル収容ケースに突起部を設 け、この突起部を取付板に形成された通孔に挿入して突起部の頭部を潰して力しめ 付けるようにしても、また、コイル収容ケースの突起部を取付板に形成された通孔に 圧入するものであっても、コイル収容ケースと取付板とを溶接するものであってもよ ヽ 発明の効果  [0011] As a joining structure between the coil housing case and the mounting plate, a projection is provided in the coil housing case, and the projection is inserted into a through hole formed in the mounting plate to crush the head of the projection. The coil housing case may be press-fitted into the through hole formed in the mounting plate, or the coil housing case and the mounting plate may be welded.効果 Effect of the invention
[0012] 以上述べたように、この発明によれば、電磁クラッチの励磁コイルを収容するコイル 収容ケースとこのコイル収容ケースを所定箇所に取り付ける取付板とをシートを間に 介在させて接合するようにしたので、コイル収容ケースと取付板との接合強度を向上 させることが可能となり、また、コイル収容ケースの振動を低減させることが可能となる 図面の簡単な説明  [0012] As described above, according to the present invention, the coil housing case that houses the exciting coil of the electromagnetic clutch and the mounting plate that attaches the coil housing case to a predetermined location are joined with the sheet interposed therebetween. Therefore, it is possible to improve the bonding strength between the coil housing case and the mounting plate, and to reduce the vibration of the coil housing case.

The first plate 16 and the second plate 17 are integrally fixed with rivets 18 and 19 at a predetermined interval.
[0020] 従動回転体 5は、従動機器の回転軸 20の先端部にインボリユートスプライン継手に より嵌合され、ボルト 21で軸方向に固定されたノヽブ 22を有して構成されている。この ハブ 22は、径方向に延設されたフランジ部 22aを備え、このフランジ部 22aを第 2プ レート 17の外側に配置させて!/、る。 [0020] The driven rotator 5 is connected to an involuntary spline joint at the tip of the rotary shaft 20 of the driven device. It is configured to have a knob 22 that is more fitted and fixed in the axial direction with a bolt 21. The hub 22 includes a flange portion 22a extending in the radial direction, and the flange portion 22a is disposed outside the second plate 17! /.
[0021] さらに、フランジ部 22aの裏面には、リベット 23により固定された板ばね 24が取り付 けられている。この板ばね 24は、その一部が第 2プレート 17の外縁近傍でリベット 25 により固定されており、リベット 23とリベット 25との間にゴムストッパ 26を取り付け、この ゴムストッパ 26を第 2プレート 17に当接させることでガタつかないようにプリセットをか けている。 Further, a leaf spring 24 fixed by a rivet 23 is attached to the back surface of the flange portion 22a.

[0022] 前記コイル収容ケース 6と取付板 8との間には、例えば接着性があるシート 30が配 設され、コイル収容ケース 6と取付板 8とは、このシート 30に密着させた状態で結合さ れている。ここで、シート 30としては、例えば、ベース素材をポリエステル不織布とし、 その表面に粉末エポキシ榭脂を均一に融着させたもの等を用いるとよい。また、コィ ル収容ケース 6と取付板 8との結合は、コイル収容ケース 6の底部 6cの中程を内側か らプレスにより押し出して突起部 6aを形成し、この突起部 6aを取付板 8に形成された 通孔 8aに挿入し、突起部 6aの先端を潰して力しめることにより実現されて 、る。  [0022] Between the coil housing case 6 and the mounting plate 8, for example, an adhesive sheet 30 is disposed, and the coil housing case 6 and the mounting plate 8 are in close contact with the sheet 30. Are connected. Here, as the sheet 30, for example, a polyester non-woven fabric is used as the base material, and powder epoxy resin is uniformly fused on the surface thereof. In addition, the coil housing case 6 and the mounting plate 8 are joined by pressing the center of the bottom portion 6c of the coil housing case 6 from the inside by pressing to form a protruding portion 6a, and this protruding portion 6a is attached to the mounting plate 8. It is realized by inserting into the formed through-hole 8a and crushing the tip of the projection 6a and applying force.
[0023] この例において、取付板 8は環状に形成され、シート 30は、図 2に示されるように環 状に形成されて、コイル収容ケース 6の取付板 8が対向する部分の全周に亘つて設 けられている。また、突起部 6aは、コイル収容ケース 6の周方向で略等間隔に例えば 4箇所設けられている。このため、取付板 8の通孔 8aも周方向で略等間隔に例えば 4 箇所設けられ、シート 30にはこれに対応して周方向で略等間隔に例えば 4箇所の通 孔 30aが形成されている。  [0023] In this example, the mounting plate 8 is formed in an annular shape, and the seat 30 is formed in an annular shape as shown in FIG. It is set up across the board. Further, for example, four protrusions 6a are provided at substantially equal intervals in the circumferential direction of the coil housing case 6. For this reason, the through holes 8a of the mounting plate 8 are also provided, for example, at four positions at approximately equal intervals in the circumferential direction, and the sheet 30 is provided with, for example, four through holes 30a at approximately equal intervals in the circumferential direction. ing.
[0024] 上述の構成において、電磁クラッチ 1は、先ず、コイル収容ケース 6に形成された突 起部 6aをシート 30の通孔 30aと取付板 8の通孔 8aとに挿入し、その先端部を潰すこ とにより取付板 8をコイル収容ケース 6にシート 30を介して力しめ付け、コイル収容ケ ース 6にコイル 2を収容した後にコイル収容部 6bにエポキシ榭脂などの熱硬化剤を充 填して熱処理を行なう。これにより、コイル収容部 6bの熱硬化剤が溶融されてコイル 2 はコイル収容ケース内に固着され、それと同時にシート 30の表面のエポキシ榭脂が 溶融されてコイル収容ケースと取付板とがシート 30に密着し、間に隙間が形成されな い状態で固定される。 [0024] In the configuration described above, the electromagnetic clutch 1 first inserts the protruding portion 6a formed in the coil housing case 6 into the through hole 30a of the seat 30 and the through hole 8a of the mounting plate 8, and the tip portion thereof. By crushing, the mounting plate 8 is pressed against the coil housing case 6 via the sheet 30, and after the coil 2 is housed in the coil housing case 6, a thermosetting agent such as epoxy grease is applied to the coil housing portion 6b. Fill and heat-treat. As a result, the thermosetting agent in the coil housing portion 6b is melted and the coil 2 is fixed in the coil housing case, and at the same time, the epoxy resin on the surface of the sheet 30 is melted so that the coil housing case and the mounting plate are connected to the sheet 30. And there is no gap between them. It is fixed in the state.
[0025] したがって、従動機器のハウジング 9は、これが取り付けられている箇所の振動によ り、或いは、ァーマチュア 4のロータ 3への吸着ゃァーマチュア 4のロータ 3からの離脱 等の衝撃などによって振動することになる力 取付板 8は、コイル収容ケース 6に対し て 4箇所の突起部 6aで固定されているものの、間にシート 30が介在されて取付板 8と コイル収容ケース 6とがこのシート 30に密着されて!、るので、コイル収容ケース 6と取 付板 8との接着強度を向上させることができ、また、取付板 8に対するコイル収容ケー ス 6の振動を低減させることで、カゝしめ部の破損を回避すると共に騒音レベルを低減 することが可能となる。  [0025] Accordingly, the housing 9 of the driven device vibrates due to vibrations at a place where the housing 9 is attached, or due to an impact such as separation of the armature 4 from the rotor 3 or the like. The force to be attached The mounting plate 8 is fixed to the coil housing case 6 by four protrusions 6a, but the seat 30 is interposed between the mounting plate 8 and the coil housing case 6 so that the seat 30 Therefore, the adhesive strength between the coil housing case 6 and the mounting plate 8 can be improved, and the vibration of the coil housing case 6 with respect to the mounting plate 8 can be reduced to It is possible to avoid damage to the crimped portion and reduce the noise level.
[0026] また、シート 30として接着性のものが採用されているので、このシート 30の接着機 能によりコイル収容ケース 6と取付板 8とは強固に接着されることになり、従来の突起 部 6aだけでの局所的な保持構造に比べて接合強度を向上させることが可能となる。 さらに、コイル収容ケース 6にコイル 2を榭脂モールドする過程の熱処理によって、シ ート 30によるコイル収容ケース 6と取付板 8との接合も同時に完了させることが可能と なる。  [0026] Further, since an adhesive material is used as the sheet 30, the coil housing case 6 and the mounting plate 8 are firmly bonded by the bonding function of the sheet 30, and the conventional protrusion Compared to the local holding structure with only 6a, the bonding strength can be improved. Further, by the heat treatment in the process of resin-molding the coil 2 in the coil housing case 6, the joining of the coil housing case 6 and the mounting plate 8 by the sheet 30 can be completed at the same time.
[0027] 尚、上述の構成においては、シート 30をコイル収容ケース 6や取付板 8の形状に合 わせて環状に形成し、シート 30をコイル収容ケース 6の取付板 8が対畤する部分の 全周に亘つて設けるようにした力 シート 30を複数の分割シートによって構成し、コィ ル収容ケース 6の取付板 8が対畤する部分の周方向に断続的に設けるようにしてもよ い。  In the above-described configuration, the sheet 30 is formed in an annular shape according to the shape of the coil housing case 6 and the mounting plate 8, and the sheet 30 is formed at the portion where the mounting plate 8 of the coil housing case 6 faces. The force sheet 30 provided over the entire circumference may be constituted by a plurality of divided sheets, and may be provided intermittently in the circumferential direction of the portion where the mounting plate 8 of the coil housing case 6 faces.
[0028] 例えば、図 3に示されるように、シート 30を 4つの短冊状の分割シート 31a, 31b, 3 lc, 31dによって構成し、それぞれの分割シートにコイル収容ケース 6の底部 6cに形 成された突起部 6aを挿入させる通孔 30aを形成し、この通孔 30aに突起部 6aを挿入 させてコイル収容ケース 6の底部 6cに周方向で間隔をあけて断続的に配設するよう にしても、また、図 4に示されるように、シート 30を 4つの短冊状の分割シート 32a, 32 b, 32c, 32dによって構成し、それぞれの分割シートを収容ケース 6の底部 6cの突起 部 6a間に配置することで周方向に断続的に設け、コイル収容ケース 6の底部 6cとこ れに対畤する取付板 8との間に挟み込むようにしてもよ!、。 [0029] これらの構成においても、コイル収容ケース 6と取付板 8とをシート 30に密着させた 状態で接合できるので、従来よりも接合強度を高めることができ、また、コイル収容ケ ース 6の振動を低減させることが可能となる。 [0028] For example, as shown in FIG. 3, the sheet 30 is composed of four strip-shaped divided sheets 31a, 31b, 3 lc, and 31d, and each divided sheet is formed on the bottom 6c of the coil housing case 6. A through hole 30a for inserting the projected portion 6a is formed, and the projected portion 6a is inserted into the through hole 30a so as to be intermittently disposed in the bottom portion 6c of the coil housing case 6 at intervals in the circumferential direction. However, as shown in FIG. 4, the sheet 30 is composed of four strip-shaped divided sheets 32a, 32b, 32c, and 32d, and each divided sheet is formed as a protrusion 6a on the bottom 6c of the storage case 6. It may be provided intermittently in the circumferential direction by being placed between them, and sandwiched between the bottom 6c of the coil housing case 6 and the mounting plate 8 facing it! [0029] In these configurations as well, since the coil housing case 6 and the mounting plate 8 can be joined in close contact with the sheet 30, the joining strength can be increased as compared with the conventional case, and the coil housing case 6 It becomes possible to reduce the vibration.
[0030] さらに、上述の構成においては、コイル収容ケース 6に取付板 8を力しめ付ける構造 を前提とした力 コイル収容ケース 6と取付板 8とは、スポット的に溶接されるものであ つても、コイル収容ケース 6に形成された突起部 6aを取付板 8に形成された通孔 8a に圧入する接合構造を前提としてもよ!ヽ。  [0030] Furthermore, in the above-described configuration, the force coil housing case 6 and the mounting plate 8 are assumed to be spot-welded on the premise of a structure in which the mounting plate 8 is force-fitted to the coil housing case 6. However, it is possible to assume a joint structure in which the protrusion 6a formed on the coil housing case 6 is press-fitted into the through hole 8a formed on the mounting plate 8!ヽ.
