Description

本発明は、軸と回転体（歯車、スプロケット、継手等）を、キーを使用しないで締結するための締結具に関する。   The present invention relates to a fastener for fastening a shaft and a rotating body (gear, sprocket, joint, etc.) without using a key.

図４乃至図６は、従来のこの種の締結具の軸方向断面図である。
図４の締結具５０は、軸５５に外側から嵌合される円筒状内周面と、テーパ状外周面とを有するインナーリング５１と、ボス孔に内側から嵌合される円筒状外周面と、インナーリング５１のテーパ状外周面と相補い合うテーパ状内周面とを有するアウターリング５２と、軸５５に外側から嵌合される円筒状内周面と、ボス孔に内側から嵌合される円筒状外周面とを有する加圧スリーブ５６と、軸５５に外側から嵌合される円筒状内周面と、軸方向孔とを有する加圧フランジ５７と、回転体５４に形成された螺子孔に軸方向孔を貫通して螺合するボルト５３とを有してなるものである。 4 to 6 are axial sectional views of a conventional fastener of this type.
4 includes an inner ring 51 having a cylindrical inner peripheral surface fitted to the shaft 55 from the outside and a tapered outer peripheral surface, and a cylindrical outer peripheral surface fitted from the inner side to the boss hole. The outer ring 52 having a tapered inner peripheral surface that complements the tapered outer peripheral surface of the inner ring 51, a cylindrical inner peripheral surface that is fitted to the shaft 55 from the outside, and a boss hole that is fitted from the inside. A pressure sleeve 56 having a cylindrical outer peripheral surface, a cylindrical inner peripheral surface fitted to the shaft 55 from the outside, a pressure flange 57 having an axial hole, and a screw hole formed in the rotating body 54 And a bolt 53 threaded through the axial hole.

この締結具５０では、インナーリング５１の軸方向位置決めのために、回転体５４のボス孔に段部５８が設けられている。また、軸５５と回転体５４との角度誤差の防止、すなわち、両者間のセンタリングのために、回転体５４には、軸５５と接する、比較的長い案内部５９が設けられなければならない。   In the fastener 50, a step portion 58 is provided in the boss hole of the rotating body 54 in order to position the inner ring 51 in the axial direction. Further, in order to prevent an angular error between the shaft 55 and the rotating body 54, that is, for centering between them, the rotating body 54 must be provided with a relatively long guide portion 59 in contact with the shaft 55.

しかし、加圧スリーブ５６、加圧フランジ５７等の部品の数が多く、さらには、回転体５４に段部５８や案内部５９を加工しなければならないことや、締結具５０の装着の際、回転体５４の方向性に注意しなければならないことから、製作・取付けのために、比較的多くの工数がかかるという問題を有する。
また、アウターリング５２に取外し用螺子孔がないため、締結時にボルト５３を締めすぎていた場合は、軸５５・回転体５４・テーパ面でかじり等が起こり取外しが困難になる場合がある。 However, the number of parts such as the pressure sleeve 56 and the pressure flange 57 is large, and further, it is necessary to process the stepped portion 58 and the guide portion 59 in the rotating body 54, and when the fastener 50 is mounted. Since attention must be paid to the directionality of the rotating body 54, there is a problem that a relatively large number of man-hours are required for manufacturing and mounting.
Further, since there is no screw hole for removal in the outer ring 52, if the bolt 53 is tightened too much at the time of fastening, the shaft 55, the rotating body 54, and the taper surface may be galled and the like may be difficult to remove.

この改良型が、図５に示す締結具６０である（特許文献１参照。）。この締結具６０は、ボス孔に内側から嵌合される円筒状外周面と、テーパ状内周面と、テーパ状内周面の小径側に形成され軸６５に外側から嵌合される顎部６６と、テーパ状内周面の大径側に形成された円筒状内周面と、テーパ状内周面の大径側端部に形成された拡径鍔部６７と、軸方向のスリット（図示せず。）とを有するアウターリング６２と、軸６５に外側から嵌合される円筒状内周面と、アウターリング６２のテーパ状内周面と相補い合うテーパ状外周面と、テーパ状外周面の大径側に形成されアウターリング６２の円筒状内周面と相補い合う円筒状外周面と、テーパ状外周面の大径側端部に形成された拡径フランジ部６８と、拡径フランジ部６８に形成された軸方向孔と、軸方向のスリット（図示せず。）とを有するインナーリング６１と、回転体６４に形成された螺子孔に軸方向孔を貫通して螺合するボルト６３とを有してなるものである。   This improved type is a fastener 60 shown in FIG. 5 (see Patent Document 1). The fastener 60 includes a cylindrical outer peripheral surface fitted into the boss hole from the inside, a tapered inner peripheral surface, and a jaw portion formed on the small diameter side of the tapered inner peripheral surface and fitted to the shaft 65 from the outside. 66, a cylindrical inner peripheral surface formed on the large-diameter side of the tapered inner peripheral surface, a large-diameter flange 67 formed on the large-diameter end of the tapered inner peripheral surface, and an axial slit ( An outer ring 62 having an outer ring 62, a cylindrical inner peripheral surface fitted to the shaft 65 from the outside, a tapered outer peripheral surface complementary to the tapered inner peripheral surface of the outer ring 62, and a tapered outer periphery. A cylindrical outer peripheral surface which is formed on the large-diameter side of the surface and complements the cylindrical inner peripheral surface of the outer ring 62; a large-diameter flange portion 68 formed on the large-diameter end of the tapered outer peripheral surface; Inner ring having an axial hole formed in the portion 68 and an axial slit (not shown). 61, is made of a bolt 63 screwed into the screw holes formed in the rotating body 64 through the axial bore.

この締結具６０によれば、フランジ部６８がインナーリング６１と一体になっており、フランジ部６８には取外し用螺子孔が付いているため、取付け・取外しが比較的容易である。
また、図４の段部５８の機能をアウターリング６２に付与することにより、回転体６４のボス孔に段付加工を施す必要がなくなり、ボス孔は単なる丸孔形状でよくなった。従って、ボス孔の加工が容易であるとともに、精度の良い孔加工を施すことができる。また、回転体６４を組付ける際、方向性に注意を払う必要がなくなる。また、テーパ面の両側において、回転体６４と軸６５を案内してセンタリングをすることができる。 According to the fastener 60, the flange portion 68 is integrated with the inner ring 61, and the flange portion 68 is provided with a screw hole for removal, so that attachment and removal are relatively easy.
Further, by providing the outer ring 62 with the function of the stepped portion 58 of FIG. 4, it is not necessary to perform a stepping process on the boss hole of the rotating body 64, and the boss hole may be a simple round hole shape. Therefore, the boss hole can be easily processed and the hole can be precisely processed. Further, when assembling the rotating body 64, it is not necessary to pay attention to the directionality. Further, the rotating body 64 and the shaft 65 can be guided and centered on both sides of the tapered surface.

次に、図６の締結具７０は、ボス孔に内側から嵌合される円筒状外周面と、テーパ状内周面とを有し、螺子孔が形成されたアウターリング７２と、軸７５に外側から嵌合される円筒状外周面と、アウターリング７２のテーパ状内周面と相補い合うテーパ状外周面と、テーパ状外周面の大径側端部に形成された拡径フランジ部７８と、拡径フランジ部７８に形成された軸方向孔とを有するインナーリング７１と、アウターリング７２に形成された螺子孔にインナーリング７１に形成された軸方向孔を貫通して螺合するボルト７３とを有してなるものである。   Next, the fastener 70 of FIG. 6 has a cylindrical outer peripheral surface fitted into the boss hole from the inside and a tapered inner peripheral surface, and an outer ring 72 having a screw hole and a shaft 75. A cylindrical outer peripheral surface fitted from the outside, a tapered outer peripheral surface complementary to the tapered inner peripheral surface of the outer ring 72, and a diameter-enlarging flange portion 78 formed at the large-diameter end of the tapered outer peripheral surface; An inner ring 71 having an axial hole formed in the diameter-enlarging flange portion 78, and a bolt 73 that is screwed into the screw hole formed in the outer ring 72 through the axial hole formed in the inner ring 71. It has.

この締結具７０では、締結時に回転体７４端面とフランジ部７８端面を当接させることにより、回転体７４の移動を防いでいる。従って、ボルト７３の締付力を大きくすると、アウターリング７２のみがフランジ部７８側に移動し、回転体７４の位置は変わることはない。
実開平４−６３８２０号公報 In the fastener 70, the end face of the rotating body 74 and the end face of the flange portion 78 are brought into contact with each other at the time of fastening to prevent the rotating body 74 from moving. Therefore, when the tightening force of the bolt 73 is increased, only the outer ring 72 moves to the flange portion 78 side, and the position of the rotating body 74 does not change.
Japanese Utility Model Publication No. 4-63820

しかし、図５の締結具６０の場合、製造公差、形状より、インナーリング６１が先に軸に対して固定されるため、ボルトの締付力を増す程、回転体６４とアウターリング６２はフランジ部６８に移動するという問題を有する。
また、図６の締結具７０の場合、アウターリング７２の中にボルト７３が入るため、ボス孔内径を大きくする必要があり、その結果、回転体７４が大きくなってしまうという問題を有する。 However, in the case of the fastener 60 of FIG. 5, the inner ring 61 is first fixed to the shaft due to manufacturing tolerances and shapes, so that the rotating body 64 and the outer ring 62 are flanged as the bolt tightening force increases. There is a problem of moving to section 68.
Further, in the case of the fastener 70 of FIG. 6, since the bolt 73 is inserted into the outer ring 72, it is necessary to increase the inner diameter of the boss hole. As a result, there is a problem that the rotating body 74 becomes large.

本発明は、ボス孔を有する回転体と軸との締結具であって、前記軸に外側から嵌合される円筒状内周面と、テーパ状外周面とを有するインナーリングと、前記ボス孔に内側から嵌合される円筒状外周面と、前記インナーリングのテーパ状外周面と相補い合うテーパ状内周面と、前記テーパ状内周面の小径側に形成された円筒状内周面と、前記テーパ状内周面の小径側端部に形成された拡径フランジ部と、該拡径フランジ部に形成された軸方向孔とを有するアウターリングと、前記回転体に形成された螺子孔に前記軸方向孔を貫通して螺合するボルトとを有してなる締結具によって、前記の課題を解決した。   The present invention is a fastener between a rotating body having a boss hole and a shaft, and an inner ring having a cylindrical inner peripheral surface fitted to the shaft from the outside, a tapered outer peripheral surface, and the boss hole A cylindrical outer peripheral surface fitted to the inner ring, a tapered inner peripheral surface complementary to the tapered outer peripheral surface of the inner ring, and a cylindrical inner peripheral surface formed on the small diameter side of the tapered inner peripheral surface; , An outer ring having an enlarged diameter flange portion formed at the small diameter side end of the tapered inner peripheral surface, an axial hole formed in the enlarged diameter flange portion, and a screw hole formed in the rotating body The above-mentioned problem has been solved by a fastener having a bolt that is screwed through the axial hole.

本発明によれば、フランジとアウターリングとを一体にした構成上の特徴により、インナーリングが先に軸に固定されることから、回転体の軸方向移動が防がれ、その結果、締結具を取付ける際の位置合わせが容易になって、締結のための作業効率を上げることができる。
また、ボルトがアウターリング内になく、回転体に直接締結されるため、コンパクトな設計が可能となる。
さらに、アウターリングに分解用螺子孔を設けることで、締結具の取外しを容易に行うことができる。 According to the present invention, the inner ring is first fixed to the shaft by the structural feature in which the flange and the outer ring are integrated, so that the axial movement of the rotating body is prevented, and as a result, the fastener Positioning at the time of mounting is facilitated, and work efficiency for fastening can be increased.
Further, since the bolt is not in the outer ring and is directly fastened to the rotating body, a compact design is possible.
Furthermore, the fastener can be easily removed by providing a screw hole for disassembly in the outer ring.

図１は、本発明の軸と回転体の締結具の軸方向断面図である。この締結具１０は、インナーリング２０、アウターリング３０、及びボルト４０を有してなる。 図１に示されるように、インナーリング２０は、軸１２の直径に対して僅かに大きい直径の円筒状内周面２４と、テーパ状外周面２２とが形成されたものである。また、このインナーリング２０は、軸方向に貫通するスリット２３（図３参照。）を有する。   FIG. 1 is a sectional view in the axial direction of a fastener for a shaft and a rotating body according to the present invention. The fastener 10 includes an inner ring 20, an outer ring 30, and a bolt 40. As shown in FIG. 1, the inner ring 20 is formed with a cylindrical inner peripheral surface 24 having a diameter slightly larger than the diameter of the shaft 12 and a tapered outer peripheral surface 22. The inner ring 20 has a slit 23 (see FIG. 3) penetrating in the axial direction.

一方、アウターリング３０は、回転体１４のボス孔１５の内径に対して僅かに小さい直径の円筒状外周面３１と、インナーリング２０のテーパ状外周面２２と相補い合うテーパ状内周面３２と、テーパ状内周面３２の小径側に形成された円筒状内周面３４と、テーパ状内周面３２の小径側端部に拡径フランジ部３６とを有する。拡径フランジ部３６には、ボルト４０を挿通しうる軸方向孔３７と分解用螺子（タップ）孔３８（図２参照。）とが形成されている。
このアウターリング３０は、軸方向のスリット３３（図３参照。）を有する。各々のスリット３３は、テーパ状内周面３２の大径側の端部から拡径フランジ部３６の近傍まで延びている。 On the other hand, the outer ring 30 includes a cylindrical outer peripheral surface 31 having a diameter slightly smaller than the inner diameter of the boss hole 15 of the rotating body 14, and a tapered inner peripheral surface 32 that complements the tapered outer peripheral surface 22 of the inner ring 20. The cylindrical inner peripheral surface 34 is formed on the small diameter side of the tapered inner peripheral surface 32, and the enlarged diameter flange portion 36 is provided on the small diameter side end of the tapered inner peripheral surface 32. The diameter-enlarged flange portion 36 is formed with an axial hole 37 through which the bolt 40 can be inserted and a disassembling screw (tap) hole 38 (see FIG. 2).
The outer ring 30 has an axial slit 33 (see FIG. 3). Each slit 33 extends from the end on the large diameter side of the tapered inner peripheral surface 32 to the vicinity of the enlarged diameter flange portion 36.

上記の締結具１０により、軸１２と回転体１４とを締結する操作は以下の通りである。
ボス孔１５と螺子孔１７が加工された回転体１４と軸１２との間に、図１のように締結具１０が装入される。所定の締付トルクでそれぞれのボルト４０が締付けられる。その際、製造における公差、形状の関係上、インナーリング２０の円筒状内周面２４と軸１２の外周面１３の間に最初に面圧が発生し、インナーリング２０の位置が固定される。 The operation of fastening the shaft 12 and the rotating body 14 with the fastener 10 is as follows.
The fastener 10 is inserted between the rotating body 14 in which the boss hole 15 and the screw hole 17 are processed and the shaft 12 as shown in FIG. Each bolt 40 is tightened with a predetermined tightening torque. At this time, due to manufacturing tolerances and shapes, a surface pressure is first generated between the cylindrical inner peripheral surface 24 of the inner ring 20 and the outer peripheral surface 13 of the shaft 12, and the position of the inner ring 20 is fixed.

その後、アウターリング３０の円筒状外周面３１と回転体１４のボス孔１５の内周面１６との間で面圧が発生する。さらに締めていくと、回転体１４の移動は伴わずに、アウターリング３０のみインナーリング２０側に移動し、それぞれのテーパ面２２，３２が係合して、楔作用により軸１２側及び回転体１４側に締付力が発生する。すなわち、軸１２の外周面１３とインナーリング２０の円筒状内周面２４との間、回転体１４のボス孔１５の内周面１６とアウターリング３０の円筒状外周面３１との間において、テーパ面２２，３２の楔作用に基づく締付力が発生し、面圧として作用する。従って、この面圧によって軸１２と回転体１４は強固に締結され、摩擦力によってトルクを伝達することができる。   Thereafter, a surface pressure is generated between the cylindrical outer peripheral surface 31 of the outer ring 30 and the inner peripheral surface 16 of the boss hole 15 of the rotating body 14. When further tightened, only the outer ring 30 moves to the inner ring 20 side without the movement of the rotating body 14, and the respective tapered surfaces 22 and 32 are engaged with each other. A tightening force is generated on the 14 side. That is, between the outer peripheral surface 13 of the shaft 12 and the cylindrical inner peripheral surface 24 of the inner ring 20, between the inner peripheral surface 16 of the boss hole 15 of the rotating body 14 and the cylindrical outer peripheral surface 31 of the outer ring 30, A clamping force based on the wedge action of the tapered surfaces 22 and 32 is generated and acts as a surface pressure. Therefore, the shaft 12 and the rotating body 14 are firmly fastened by this surface pressure, and torque can be transmitted by frictional force.

この締結具１０を分解するには、ボルト４０を全て抜取り、そのボルト４０又は別途用意した同サイズのボルトを分解用螺子（タップ）孔３８にねじ込んでボルト４０の先端を回転体１４に当接させ、回転体１４とアウターリング３０とを引離す力を作用させて行う。インナーリング２０には、軸方向貫通スリット２３が設けられているので、締付状態で拡開していたインナーリング２０は、締付が解除されると原形状に復帰し、容易に引出すことができる。
なお、分解用螺子孔３８には、高速回転に対応するため、バランスウェイトを付けることも可能である。 In order to disassemble the fastener 10, all the bolts 40 are removed, and the bolts 40 or bolts of the same size separately prepared are screwed into disassembly screw (tap) holes 38, and the tips of the bolts 40 are brought into contact with the rotating body 14. And a force for separating the rotating body 14 and the outer ring 30 is applied. Since the inner ring 20 is provided with the axial through slit 23, the inner ring 20 that has been expanded in the tightened state returns to the original shape when the tightening is released and can be easily pulled out. it can.
The disassembly screw hole 38 can be provided with a balance weight in order to cope with high-speed rotation.

なお、これまで、本発明の締結具はインナーリングもアウターリングもスリットを有するものとして説明してきたが、これに限るものではなく、どちらかにスリットがあるものであっても、いずれにもスリットがないものであってもよい。また、スリットの形状についても、貫通スリットであるか、途中までのスリットであるかは、適宜選択できるものである。   Heretofore, the fastener of the present invention has been described as having both an inner ring and an outer ring having slits. However, the present invention is not limited to this. There may be no. Also, the shape of the slit can be appropriately selected as to whether it is a through slit or a halfway slit.

以上説明したように、本発明によれば、フランジとアウターリングとを一体にすることで、締結に際して回転体の移動がなくなるので、締結具を取付ける際の位置合わせを容易に行うことができ、その結果、作業効率を大幅に上げることができる。
また、ボルトがアウターリング内になく、回転体に直接締結されるため、コンパクトな設計が可能となるという効果を奏する。
さらに、アウターリングに分解用螺子孔を設けることで、締結具の取外しを容易に行うことができるという効果を奏する。 As described above, according to the present invention, by integrating the flange and the outer ring, there is no movement of the rotating body at the time of fastening, so it is possible to easily perform alignment when attaching the fastener, As a result, work efficiency can be greatly increased.
Moreover, since the bolt is not in the outer ring and is directly fastened to the rotating body, there is an effect that a compact design is possible.
Furthermore, by providing the disassembly screw hole in the outer ring, there is an effect that the fastener can be easily removed.
