本発明は、駆動力伝達構造に関し、特に、鋼板等の形状を矯正するローラレベラに回転駆動力を伝達する駆動力伝達構造に関する。   The present invention relates to a driving force transmission structure, and more particularly to a driving force transmission structure that transmits a rotational driving force to a roller leveler that corrects the shape of a steel plate or the like.

ローラレベラは、複数のロールを上下千鳥状に配設し、鋼板等の被矯正材を通過させることによって、交互に繰り返し曲げを与えて矯正するものである。このため、各ロールは摩耗し、各ロールの補修・交換作業を必要としていた。   A roller leveler arranges a plurality of rolls in an upper and lower zigzag pattern and passes a material to be rectified such as a steel plate, thereby alternately bending and correcting it. For this reason, each roll was worn out, and repair and replacement work for each roll was required.

そこで、従来にはローラレベラにおけるロール交換が可能な支持装置が提案されている（特許文献１）。このような装置においては、ロールと駆動装置とを自在継手を介して連結されている。このため、自在継手とロールとは、例えば、ロール軸端に設けたフランジをボルトや止めねじ等で締結していた。   Therefore, conventionally, a support device capable of exchanging rolls in a roller leveler has been proposed (Patent Document 1). In such a device, the roll and the drive device are connected via a universal joint. For this reason, the universal joint and the roll are fastened with, for example, a flange provided at the roll shaft end with a bolt or a set screw.

図１９と図２０は従来のこの駆動力伝達構造を示し、駆動力伝達構造は、駆動装置（図示省略）の分配器側（ピニオンギヤ側）に接続される自在継手１と、ロール２に接続される自在継手３と、自在継手１と自在継手３とを連結する軸部材４とを備える。   19 and 20 show this conventional driving force transmission structure, which is connected to a universal joint 1 connected to a distributor side (pinion gear side) of a driving device (not shown) and to a roll 2. And a shaft member 4 that connects the universal joint 1 and the universal joint 3 to each other.

Further, a connecting insertion hole 16 is provided on the distributor side of the outer joint member 5, and a shaft portion (not shown) on the distributor side is inserted into the insertion hole 16 and is fixed by a set screw 17. .

軸部材４は、前記端部１５をその基端部に有する本体部材１８と、この本体部材１８に外嵌される外筒体１９とを備える。外筒体１９は、本体部材１８の雄スプラインに嵌合する雌スプラインを有する第１部材２０と、第１部材２０に連結される筒体からなる第２部材２１とからなる。このため、本体部材１８に対して外筒体１９は軸心方向に沿って矢印Ａ、Ｂ方向にスライド可能となっている。   The shaft member 4 includes a main body member 18 having the end portion 15 at a base end portion thereof, and an outer cylindrical body 19 that is externally fitted to the main body member 18. The outer cylindrical body 19 includes a first member 20 having a female spline that fits into a male spline of the main body member 18, and a second member 21 that is a cylindrical body connected to the first member 20. For this reason, the outer cylinder 19 is slidable in the directions of arrows A and B along the axial direction with respect to the main body member 18.

自在継手３も、自在継手１と同様、外側継手部材２５と、内側継手部材２６と、トルク伝達部材としてのボール２７とを備える。すなわち、外側継手部材２５にはボール収納室２８が設けられ、このボール収納室２８に嵌入された内側継手部材２６の嵌入部３０に、ボール２７が保持されている。また、ボール収納室２８にはその軸部に突起部３１が設けられ、この突起部３１の外径面、及びボール収納室２８の内径面には軸方向に延びるトラック溝３２，３３が設けられ、このトラック溝３２，３３にボール２７が嵌合している。   Similar to the universal joint 1, the universal joint 3 includes an outer joint member 25, an inner joint member 26, and a ball 27 as a torque transmission member. That is, the outer joint member 25 is provided with a ball storage chamber 28, and the ball 27 is held in the fitting portion 30 of the inner joint member 26 fitted into the ball storage chamber 28.

No. 7-6777

前記図１９と図２０に示す駆動力伝達構造において、ロールを交換する場合、以下の工程を行うことになる。まず、各自在継手３の止めねじ３７を緩める。次に、全継手３側を矢印Ａ方向に移動させ、図２０で示すように、継手３の外側継手部材２５をロール２の軸部３５から引き抜くことになる。また、逆に、連結する場合、全継手側を図１９の矢印Ｂ方向に移動させ、継手３の外側継手部材２５の嵌入孔３６にロール２の軸部３５を嵌入させる。次に、全継手に止めねじ３７を螺着する。   In the driving force transmission structure shown in FIGS. 19 and 20, when the roll is exchanged, the following steps are performed. First, the set screw 37 of each universal joint 3 is loosened. Next, all the joints 3 are moved in the direction of arrow A, and the outer joint member 25 of the joint 3 is pulled out from the shaft portion 35 of the roll 2 as shown in FIG. Conversely, when connecting, all joints are moved in the direction of arrow B in FIG. 19, and the shaft portion 35 of the roll 2 is inserted into the insertion hole 36 of the outer joint member 25 of the joint 3. Next, set screws 37 are screwed onto all the joints.

このように、交換時には、全継手３の止めねじの螺進退作業を行う必要があり、しかも、上下左右に配設されたロールに対して行わなければならなかった。特に、このようなローラレベラでは、ロール数は多く、２０本以上の場合がある。このため、交換作業時間が大となるとともに、作業スペースも比較的小さく、作業性に劣っていた。   As described above, at the time of replacement, it is necessary to perform the advance / retreat operation of the set screws of all the joints 3 and to the rolls arranged vertically and horizontally. In particular, such a roller leveler has a large number of rolls and may be 20 or more. For this reason, the replacement work time is increased, the work space is relatively small, and the workability is inferior.

本発明は、上記課題に鑑みて、ロールを効率よく短時間で交換できる駆動力伝達構造を提供する。   In view of the above problems, the present invention provides a driving force transmission structure capable of exchanging rolls efficiently and in a short time.

本発明の駆動力伝達構造は、複数のロールを備えたローラレベルに用いられ、駆動手段からの駆動力をロールに伝達する駆動力伝達構造であって、連結用シャフトと、この連結用シャフトとロールとの間に介装される継手とを備え、前記継手は、ロールに連結される外側継手部材と、前記シャフトのロール側端部に装着される内側継手部材と、トルク伝達部材とを有し、内側継手部材とトルク伝達部材とを含む内部部品の前記外側継手部材に対する軸方向に沿った出し入れを可能とするとともに、連結用シャフトをロール側へ押圧してシャフトのロール側の端縁を前記外側継手部材の押し当て面に押し当てて、前記内部部品が外側継手部材に収容された状態を維持するための弾性部材を、前記シャフトに付設し、各連結用シャフトにおいて、内部部品が外側継手部材に収容された状態からの弾性部材の弾発付勢力に抗した連結用シャフトの反外側継手部材側への同時押圧力付与によって、外側継手部材からの一度の抜き出しが可能であるものである。 The driving force transmission structure of the present invention is a driving force transmission structure that is used for a roller level provided with a plurality of rolls, and that transmits the driving force from the driving means to the rolls. A joint interposed between the roll and the joint, the joint having an outer joint member connected to the roll, an inner joint member attached to a roll side end of the shaft, and a torque transmission member. The inner part including the inner joint member and the torque transmission member can be inserted into and removed from the outer joint member in the axial direction, and the connecting shaft is pressed toward the roll side to thereby remove the end of the shaft on the roll side. is pressed against the pressing surface of the outer joint member, an elastic member for maintaining a state in which the internal components are housed in the outer joint member, and attached to the shaft, in each of the connecting shaft, The joint shaft can be pulled out from the outer joint member once by applying simultaneous pressing force to the opposite outer joint member side of the connecting shaft against the elastic biasing force of the elastic member from the state in which the parts are accommodated in the outer joint member It is what is.

本発明の駆動力伝達構造によれば、連結状態では、弾性部材にて連結用シャフトのロール側の端縁が外側継手部材の押し当て面に押し当てられた状態で、内部部品が外側継手部材に収容された状態を維持する。このため、ロールはこの駆動力伝達構造を介して連結された状態が維持され、駆動手段からの駆動力が駆動力伝達構造を介してロールに伝達され、ロールが回転する。   According to the driving force transmission structure of the present invention, in the connected state, the inner part is the outer joint member in a state where the roll-side edge of the connecting shaft is pressed against the pressing surface of the outer joint member by the elastic member. To maintain the state of being housed. For this reason, the state where the rolls are connected via the driving force transmission structure is maintained, the driving force from the driving means is transmitted to the rolls via the driving force transmission structure, and the roll rotates.

この連結状態から、弾性部材の弾発付勢力に抗してシャフトを外側継手部材と反対方向への引き抜き力を付与すれば、外側継手部材に収容されている内部部品をこの外側継手部材から引き抜くことができる。すなわち、多数のロールを備えたローラレベラであっても、外側継手部材がロールに取り付けられた状態で、シャフト側とロール側とを分離することができる。   From this connected state, if a pulling force in the direction opposite to the outer joint member is applied against the elastic urging force of the elastic member, the internal component housed in the outer joint member is pulled out from the outer joint member. be able to. That is, even in a roller leveler having a large number of rolls, the shaft side and the roll side can be separated with the outer joint member attached to the roll.

また、新たな又は補修されたロールを取り付ける場合は、まず、新たな又は補修されたロールに外側継手部材を装着する。そして、弾性部材の弾発付勢力に抗してシャフトを外側継手部材と反対方向への押圧力を付与した状態で、シャフト側の軸心と、ロール側の軸心とを一致させる。この状態から、シャフトを外側継手部材へ押圧し、内部部品を外側継手部材を収容させて、この押圧力を解除する。これによって、弾性部材にて連結用シャフトのロール側の端縁が外側継手部材の押し当て面に押し当てられた状態で、内部部品が外側継手部材に収容された状態を維持する。   When a new or repaired roll is attached, the outer joint member is first attached to the new or repaired roll. Then, in a state where a pressing force is applied to the shaft in the direction opposite to that of the outer joint member against the elastic urging force of the elastic member, the shaft side axis is aligned with the roll side axis. From this state, the shaft is pressed against the outer joint member, the inner part is accommodated in the outer joint member, and the pressing force is released. Accordingly, the state in which the inner part is accommodated in the outer joint member is maintained in a state where the end of the connecting shaft on the roll side is pressed against the pressing surface of the outer joint member by the elastic member.

継手の内側継手部材は、３本の脚軸を備えたトリポード部材からなり、継手の外側継手部材は、軸方向に延びるローラ案内面を有するとともに、奥側に前記押し当て面を有する内部部品収容部を備え、前記トルク伝達部材は、前記内側継手部材の脚軸に装着されて、前記ローラ案内面に案内されるローラを備えたものが好ましい。すなわち、継手として、トリポード型のものを使用するのが好ましい。   The inner joint member of the joint is composed of a tripod member having three leg shafts, and the outer joint member of the joint has a roller guide surface extending in the axial direction and an inner part housing having the pressing surface on the back side. Preferably, the torque transmission member includes a roller that is mounted on a leg shaft of the inner joint member and is guided by the roller guide surface. That is, it is preferable to use a tripod type joint.

継手をこのように構成することによって、この継手を組み立てる場合、内側継手部材と外側継手部材とを軸心方向に沿って相対的に接近させていくことによって、外側継手部材のローラ案内面にローラがガイドされて、内部部品が外側継手部材の内部部品収容部に収納されていく。また、内側継手部材と外側継手部材とを軸心方向に沿って相対的に離間させていくことによって、外側継手部材のローラ案内面にローラがガイドされて、内部部品が外側継手部材から引き抜かれる。   By assembling the joint in this way, when assembling the joint, by moving the inner joint member and the outer joint member relatively closer along the axial direction, the roller guide surface of the outer joint member is Is guided, and the internal parts are housed in the internal part housing part of the outer joint member. Further, by relatively separating the inner joint member and the outer joint member along the axial direction, the roller is guided to the roller guide surface of the outer joint member, and the internal part is pulled out from the outer joint member. .

外側継手部材の内部部品収容部は、その周壁に周方向１２０度ピッチで切欠部が設けられ、各切欠部の周方向対向面に前記ローラ案内面を設けることができる。   The inner part accommodating portion of the outer joint member can be provided with notches on the peripheral wall at a pitch of 120 degrees in the circumferential direction, and the roller guide surfaces can be provided on the circumferentially opposed surfaces of the notches.

外側継手部材の内部部品収容部は、その周壁に３つの切欠部を設けて周方向に沿って１２０度ピッチで配設される柱部を設け、この柱部の周方向対向面に前記ローラ案内面を形成するとともに、柱部の両周方向対応面の開口側端部に、前記内部部品の内部部品収容部への侵入を案内するテーパ状侵入ガイド部を設けて、前記柱部の開口側を二等辺三角形状部とすることができる。この際、前記柱部の二等辺三角形状部の傾斜辺の成す角度を６０°〜１１０°とすることができる。また、周方向に沿って隣合う柱部の周方向に対向する傾斜辺の成す角度を６０°〜１１０°とすることができる。   The inner part accommodating portion of the outer joint member is provided with three notches on the peripheral wall thereof and provided with pillar portions arranged at a pitch of 120 degrees along the circumferential direction, and the roller guide is provided on the circumferentially facing surface of the pillar portion. A tapered intrusion guide portion that guides the intrusion of the internal component into the internal component housing portion is provided at an opening side end portion of the surface corresponding to both circumferential directions of the column portion, and an opening side of the column portion Can be an isosceles triangle. At this time, the angle formed by the inclined sides of the isosceles triangular portion of the column portion can be set to 60 ° to 110 °. Moreover, the angle which the inclined side which opposes the circumferential direction of the column part adjacent along the circumferential direction can make 60 degrees-110 degrees.

外側継手部材の内部部品収容部は、その周壁に３つの切欠部を設けて周方向に沿って１２０度ピッチで配設される柱部を設け、この柱部の周方向対向面に前記ローラ案内面を形成するとともに、柱部の一方の周方向対応面の開口側端部に、前記内部部品の内部部品収容部への侵入を案内するテーパ状侵入ガイド部を設けて、前記柱部の開口側を直角三角形状部とすることができる。この際、柱部の直角三角形状部の傾斜辺の成す角度を４０°〜６０°とすることができる。   The inner part accommodating portion of the outer joint member is provided with three notches on the peripheral wall thereof and provided with pillar portions arranged at a pitch of 120 degrees along the circumferential direction, and the roller guide is provided on the circumferentially facing surface of the pillar portion. A tapered intrusion guide portion that guides the intrusion of the internal component into the internal component housing portion is provided at an opening side end portion of one circumferential direction corresponding surface of the post portion, and the opening of the post portion is formed. The side can be a right triangle. At this time, the angle formed by the inclined sides of the right triangular portion of the column portion can be set to 40 ° to 60 °.

このように、テーパ状侵入ガイド部を設ければ、内部部品を内部部品収容部に収納する場合、このテーパ状侵入ガイド部にて内部部品がガイド（案内）されて、内部部品収容部に収容されていく。特に、内部部品の収容時に、外側継手部材のローラ案内面と内部部品とにおいて周方向の位相がずれていても、テーパ状侵入ガイド部によって位相が一致するようにガイドされる。すなわち、内部部品がテーパ状侵入ガイド部を押し付ける分力でロールを自転させて、内部部品の内部部品収容部への侵入の容易化を図っている。   As described above, when the tapered intrusion guide portion is provided, when the internal component is accommodated in the internal component accommodating portion, the internal component is guided (guided) by the tapered intrusion guide portion and accommodated in the internal component accommodating portion. It will be done. In particular, when the inner part is accommodated, even if the circumferential phase is shifted between the roller guide surface of the outer joint member and the inner part, the inner part is guided by the tapered intrusion guide portion so that the phases match. That is, the roll is rotated by the component force by which the internal component presses the tapered intrusion guide portion, thereby facilitating the penetration of the internal component into the internal component housing portion.

内部部品収容部の内面開口端縁部に開口側に向かって拡径する内周側テーパ状侵入部を設けるのも好ましい。内部部品を内部部品収容部に収納する場合、この内周側テーパ状侵入部によって、ガイドされる。この際、内周側テーパ状侵入部の傾斜角度を２０°〜４５°とすることができる。   It is also preferable to provide an inner peripheral side tapered intrusion portion that expands in diameter toward the opening side at the inner opening end edge portion of the internal component housing portion. When the internal component is stored in the internal component storage portion, it is guided by the inner peripheral side tapered intrusion portion. At this time, the inclination angle of the inner peripheral side tapered intrusion portion can be set to 20 ° to 45 °.

前記トリポード部材の脚軸の外径面に一対の対向する切欠部を形成して、この脚軸の断面形状を長円形状とするとともに、対向する切欠部を非トルク負荷位置に配置するのが好ましい。このように、脚軸の断面形状を長円形状（いわゆる小判型形状）とすることによって、潤滑油の内部への侵入（介入）が容易となる。   A pair of opposed notches are formed on the outer diameter surface of the leg shaft of the tripod member so that the cross-sectional shape of the leg shaft is an oval shape, and the opposed notches are arranged at a non-torque load position. preferable. Thus, by making the cross-sectional shape of the leg shaft into an oval shape (so-called oval shape), it is easy to enter (intervene) the lubricating oil.

本発明の駆動力伝達構造では、多数のロールを備えたローラレベラであっても、各ロールに対する螺進退作業を行う必要がなく、一度にシャフト側とロール側とを分離することができる。また、外側継手部材をロール側に連結しておき、この状態で内部部品を外側継手部材に収容することができ、一度にシャフト側とロール側とを連結することができる。このため、ローラレベラなど多段ロールを有する設備に用いれば、ロール交換など段取り替え時、操業停止時間を極めて短縮ができ製品の生産性の向上を図ることができ、有用である。   In the driving force transmission structure of the present invention, even if a roller leveler is provided with a large number of rolls, it is not necessary to perform a screw advance / retreat operation on each roll, and the shaft side and the roll side can be separated at a time. Further, the outer joint member is connected to the roll side, and the internal parts can be accommodated in the outer joint member in this state, and the shaft side and the roll side can be connected at a time. For this reason, if it is used for facilities having a multi-stage roll such as a roller leveler, the operation stop time can be extremely shortened at the time of setup change such as roll exchange, and the productivity of the product can be improved, which is useful.

継手としてトリポード型のものを使用することによって、シャフト側とロール側との連結・分離作業を容易に行うことができ、作業性の向上を図ることができる。   By using a tripod type joint as the joint, the connection / separation work between the shaft side and the roll side can be easily performed, and the workability can be improved.

また、外側継手部材の内部部品収容部の周壁に切欠部を設けることによって、ロール回転中（運転中）に、この切欠部を介した潤滑油の滴下が可能となって、潤滑性に優れることになる。   In addition, by providing a notch in the peripheral wall of the inner part housing part of the outer joint member, it is possible to drop lubricating oil through this notch during roll rotation (during operation), and excellent lubricity. become.

外側継手部材にテーパ状侵入ガイド部を設けたり、内周側状侵入ガイド部を設けたりすることによって、連結作業性の一層の向上を図ることができる。特に、テーパ状侵入ガイド部及び内周側状侵入ガイド部を設けることによって、内部部品をより滑らかに挿入（侵入）させることができる。   By providing the outer joint member with a tapered intrusion guide portion or an inner peripheral side intrusion guide portion, the connection workability can be further improved. In particular, by providing the tapered intrusion guide portion and the inner peripheral side intrusion guide portion, the internal components can be inserted (entered) more smoothly.

脚軸の断面形状を長円形状（いわゆる小判型形状）とすることによって、潤滑油の内部への侵入（介入）が容易となり、滑らかなトルク伝達が可能となって、高効率の稼動を長期にわたって安定して行うことができる。   By making the cross-sectional shape of the leg shaft into an oval shape (so-called oval shape), the lubricant can easily enter (intervene) into the interior, enabling smooth torque transmission and long-term efficient operation. Can be performed stably.

本発明に係る駆動力伝達構造の実施形態を図１〜図１８に基づいて説明する。駆動力伝達構造は、例えば、鋼板等の形状を矯正するローラレベラに回転駆動力を伝達するものである。すなわち、図１７と図１８に示すようなレベラーに使用される。   An embodiment of a driving force transmission structure according to the present invention will be described with reference to FIGS. The driving force transmission structure transmits rotational driving force to, for example, a roller leveler that corrects the shape of a steel plate or the like. That is, it is used for a leveler as shown in FIGS.

図１７に示すレベラーは、ラフレベラー５１と、ローラレベラ５２と、スリッタ５３を備えたものである。この場合、アイコイラ５４から送出される長尺状の鋼板５５を、ラフレベラー５１とローラレベラ５２とを通させて、鋼板５５の形状を矯正し、その矯正した鋼板５５に対してスリッタ５３にてスリットを形成して、リコイラ５６に巻き取っていくものである。   The leveler shown in FIG. 17 includes a leveler 51, a roller leveler 52, and a slitter 53. In this case, the long steel plate 55 sent out from the eye coiler 54 is passed through the leveler 51 and the roller leveler 52 to correct the shape of the steel plate 55, and the slitter 53 is used to slit the corrected steel plate 55. It is formed and wound around the recoiler 56.

図１８に示すレベラーは、ラフレベラー５１と、ローラレベラ５２と、シャー５７を備えたものである。この場合、アイコイラ５４から送出される長尺状の鋼板５５を、ラフレベラー５１とローラレベラ５２とを通させて、鋼板５５の形状を矯正し、その矯正した鋼板５５に対してシャー５７にて切断して、所定寸のシート体を形成するものである。   The leveler shown in FIG. 18 includes a leveler 51, a roller leveler 52, and a shear 57. In this case, the long steel plate 55 sent out from the eye coiler 54 is passed through the leveler 51 and the roller leveler 52 to correct the shape of the steel plate 55, and the corrected steel plate 55 is cut by the shear 57. Thus, a sheet body having a predetermined size is formed.

本発明に係る駆動力伝達構造は、このようなローラレベラ５２の各ロール６２を回転駆動させるためのものである。この駆動力伝達構造は、図１と図２に示すように、連結用シャフト６０と、この連結用シャフト６０と図示省略の分配器側との間に介装される継手６１と、連結用シャフト６０とロール６２との間に介装される継手６３とを備える。   The driving force transmission structure according to the present invention is for rotationally driving each roll 62 of such a roller leveler 52. As shown in FIGS. 1 and 2, the driving force transmission structure includes a connecting shaft 60, a joint 61 interposed between the connecting shaft 60 and a distributor (not shown), and a connecting shaft. And a joint 63 interposed between the roll 60 and the roll 62.

連結用シャフト６０は、継手６１側の軸部材６５と、継手６３側の軸部材６６と、軸部材６５、６６間に配設される本体６４とを備える。軸部材６５，６６はそれぞれ基部大径部６７と、先端部に雄スプライン６８が設けられた先端細径部６９と、基部大径部６７と先端細径部６９との間の中間中径部７０とを備える。   The connecting shaft 60 includes a shaft member 65 on the joint 61 side, a shaft member 66 on the joint 63 side, and a main body 64 disposed between the shaft members 65 and 66. Each of the shaft members 65 and 66 includes a base large-diameter portion 67, a tip small-diameter portion 69 provided with a male spline 68 at the tip, and an intermediate medium-diameter portion between the base large-diameter portion 67 and the tip thin-diameter portion 69. 70.

本体６４は、継手６１側の筒体からなる第１部材７１と、この第１部材７１にその一端部が嵌入される第２部材７２とを備える。第１部材７１の孔部７３は、図２に示すように、軸部材６５の基部大径部６７が嵌入される軸部材嵌入部７３ａと、第２部材７２の一端部が嵌入される第２部材嵌入部７３ｂと、軸部材嵌入部７３ａと第２部材嵌入部７３ｂとの間の大径部７３ｃとを有する。   The main body 64 includes a first member 71 made of a tubular body on the joint 61 side, and a second member 72 into which one end portion is fitted into the first member 71. As shown in FIG. 2, the hole 73 of the first member 71 includes a shaft member insertion portion 73 a into which the base large-diameter portion 67 of the shaft member 65 is inserted, and a second end into which one end of the second member 72 is inserted. It has the member insertion part 73b and the large diameter part 73c between the shaft member insertion part 73a and the 2nd member insertion part 73b.

第２部材嵌入部７３ｂの内径面には雌スプライン７４が設けられている。軸部材嵌入部７３ａと大径部７３ｃとの間には内径側へ突出する内鍔部７５が設けられている。なお、軸部材嵌入部７３ａに嵌入される軸部材６５の基部大径部６７は、キー（沈みキー）７６を介して嵌め合い固定されている。また、基部大径部６７の端面７７が内鍔部７５に当接している。   A female spline 74 is provided on the inner diameter surface of the second member insertion portion 73b. Between the shaft member insertion portion 73a and the large diameter portion 73c, an inner collar portion 75 that protrudes toward the inner diameter side is provided. The base large-diameter portion 67 of the shaft member 65 inserted into the shaft member insertion portion 73 a is fitted and fixed via a key (sink key) 76. Further, the end surface 77 of the base large diameter portion 67 is in contact with the inner flange portion 75.

第２部材７２は、頭部８０と軸部８１とを有する。頭部８０は、前記軸部材６６の基部大径部６７が嵌入する孔部８２を有する大径先端部８３と、軸部８１側の大径基端部８４と、大径先端部８３と大径基端部８４との間の小径部８５とからなる。軸部８１は、その反頭部側に雄スプライン８６が設けられ、この雄スプライン８６が第１部材７１の雌スプライン７４に嵌合している。このため、第２部材７２は、その雄スプライン８６が第１部材７１の雌スプライン７４に嵌合した状態で、矢印Ｃ、Ｄ方向に往復動可能となっている。孔部８２に嵌入される軸部材６６の基部大径部６７は、キー（沈みキー）８９を介して嵌め合い固定されている。   The second member 72 has a head portion 80 and a shaft portion 81. The head 80 includes a large-diameter tip 83 having a hole 82 into which the base large-diameter portion 67 of the shaft member 66 is fitted, a large-diameter base end 84 on the shaft 81 side, a large-diameter tip 83, and a large diameter. It consists of a small diameter part 85 between the diameter base end part 84. The shaft portion 81 is provided with a male spline 86 on the opposite head side, and the male spline 86 is fitted to the female spline 74 of the first member 71. For this reason, the second member 72 can reciprocate in the directions of arrows C and D in a state where the male spline 86 is fitted to the female spline 74 of the first member 71. The base large-diameter portion 67 of the shaft member 66 fitted into the hole portion 82 is fitted and fixed via a key (sink key) 89.

また、第２部材７２には、例えばコイルスプリングからなる弾性部材８８が装着（外嵌）されている。すなわち、弾性部材８８は、第１部材７１と、第２部材７２の頭部８０の大径基端部８４との間に介装されている。このため、第１部材７１に対して第２部材７２が矢印Ｃ方向へ押圧される。   Further, an elastic member 88 made of, for example, a coil spring is attached (externally fitted) to the second member 72. That is, the elastic member 88 is interposed between the first member 71 and the large-diameter base end portion 84 of the head portion 80 of the second member 72. For this reason, the second member 72 is pressed in the direction of arrow C against the first member 71.

継手６３は、ロール６２に連結される外側継手部材９０と、シャフト６０のロール側端部（軸部材６６の端部）に装着される内側継手部材９１と、トルク伝達部材９２とを有する。内側継手部材９１とトルク伝達部材９２とで内部部品９３を構成する。   The joint 63 includes an outer joint member 90 connected to the roll 62, an inner joint member 91 attached to a roll side end of the shaft 60 (an end of the shaft member 66), and a torque transmission member 92. The inner joint member 91 and the torque transmission member 92 constitute an internal part 93.

外側継手部材９０は、反ロール側に内部部品９３が収容される内部部品収容部９４を有するとともに、ロール側にロール６２の軸部６２ａが嵌入される嵌入部９５を有する。この嵌入部９５の奥側には中空室９６が連設されている。このため、内部部品収容部９４と中空室９６との間に仕切壁９７が設けられている。   The outer joint member 90 has an internal component accommodating portion 94 for accommodating the internal component 93 on the side opposite to the roll, and has a fitting portion 95 for fitting the shaft portion 62a of the roll 62 on the roll side. A hollow chamber 96 is continuously provided on the back side of the fitting portion 95. For this reason, a partition wall 97 is provided between the internal component housing portion 94 and the hollow chamber 96.

軸部６２ａは断面が正方形状の角軸からなり、このため、嵌入部９５は、図９に示すように、四角孔からなる。この嵌入部９５には２つのねじ孔９８，９８が連設されている。なお、２つのねじ孔９８，９８は相互に直交する方向に配置されている。このため、図１に示すように、嵌入部９５にロール６２の軸部６２ａを嵌入した状態で、ねじ孔９８，９８に止めねじＳ、Ｓが螺着することによって、ロール６２の軸部６２ａが外側継手部材９０に固定される。   The shaft portion 62a is formed of a square shaft having a square cross section. Therefore, the fitting portion 95 is formed of a square hole as shown in FIG. Two screw holes 98 and 98 are continuously provided in the fitting portion 95. The two screw holes 98, 98 are arranged in directions orthogonal to each other. Therefore, as shown in FIG. 1, with the shaft portion 62a of the roll 62 fitted in the fitting portion 95, the set screws S and S are screwed into the screw holes 98 and 98, thereby the shaft portion 62a of the roll 62. Is fixed to the outer joint member 90.

内部部品収容部９４は、図５から図８に示すように、その周壁９９に軸方向に延びる３個の切欠部１００を設けて、周方向に沿って１２０度ピッチで配設される３つの柱部１０１を形成している。また、柱部１０１の周方向対向面にローラ案内面１０２、１０２が形成される。柱部１０１の周方向対向面の開口側端部に、前記内部部品９３を案内するテーパ状侵入ガイド部１０３，１０３を設けている。これによって、柱部１０１の開口側を２等辺三角形状部１０４としている。切欠部１００の奥部が幅広部１０５（図８参照）とされている。なお、図６は図５のＺ方向矢視図であり、図７は図６のＩ方向矢視図であり、図８は図６のＨ方向矢視図である。   As shown in FIGS. 5 to 8, the internal component housing portion 94 is provided with three notches 100 extending in the axial direction on the peripheral wall 99, and is arranged at a pitch of 120 degrees along the circumferential direction. A pillar portion 101 is formed. In addition, roller guide surfaces 102 and 102 are formed on the circumferentially opposed surfaces of the column portion 101. Tapered intrusion guide portions 103 and 103 for guiding the internal component 93 are provided on the opening side end portion of the circumferentially facing surface of the column portion 101. Thus, the opening side of the column part 101 is an isosceles triangular part 104. A back portion of the cutout portion 100 is a wide portion 105 (see FIG. 8). 6 is a view in the direction of the arrow Z in FIG. 5, FIG. 7 is a view in the direction of arrow I in FIG. 6, and FIG. 8 is a view in the direction of arrow H in FIG.

テーパ状侵入ガイド部１０３は、外径側の第１部１０３ａと、内径側の第２部１０３ｂとからなる。この場合、第１部１０３ａは、軸方向に対して所定角度で傾斜し、外径面（外周面）に垂直に切断した切断面にて構成されている。すなわち、第１部１０３ａは、図７において紙面と直交する方向に沿ってカットした面である。２等辺三角形状部１０４の傾斜辺のなす角度（第１部１０３ａの成す角度）α（図７参照）を、例えば６０°〜１１０°としている。また、第２部１０３ｂは、図８において紙面と直交する方向に沿ってカットした面である。周方向に隣り合う柱部１０１、１０１の対向する傾斜辺の成す角度α１（図８参照）を、例えば６０°〜１１０°としている。なお、２等辺三角形状部１０４の頂点は例えば図７において紙面と直交する方向に沿った平坦部１０６、即ち外側継手部材９０の端面である。   The tapered intrusion guide portion 103 includes an outer diameter side first portion 103a and an inner diameter side second portion 103b. In this case, the first portion 103a is configured by a cut surface that is inclined at a predetermined angle with respect to the axial direction and cut perpendicularly to the outer diameter surface (outer peripheral surface). That is, the first part 103a is a surface cut along a direction orthogonal to the paper surface in FIG. An angle formed by the inclined sides of the isosceles triangular portion 104 (an angle formed by the first portion 103a) α (see FIG. 7) is, for example, 60 ° to 110 °. The second part 103b is a surface cut along a direction orthogonal to the paper surface in FIG. An angle α1 (see FIG. 8) formed by the inclined sides facing each other of the column parts 101 adjacent to each other in the circumferential direction is set to 60 ° to 110 °, for example. Note that the vertex of the isosceles triangular portion 104 is, for example, the flat portion 106 along the direction orthogonal to the paper surface in FIG. 7, that is, the end surface of the outer joint member 90.

等辺三角形状部１０４の内面開口端縁部には奥側から開口部に向かって拡径する内面側テーパ状侵入ガイド部１０７が設けられている。この内面側テーパ状侵入ガイド部１０７の傾斜角度γ（図５参照）を２０°〜４５°とする。なおテーパ状進入ガイド部１０３ａ、１０３ｂ平坦部１０６及び内径側テーパ状進入ガイド部１０７同士それぞれが相互に形成する稜線はシャープエッジなきよう常識的な丸みが施されている。   An inner surface side tapered intrusion guide portion 107 whose diameter increases from the inner side toward the opening portion is provided at the inner edge opening edge portion of the equilateral triangular portion 104. The inclination angle γ (see FIG. 5) of the inner surface side tapered intrusion guide portion 107 is set to 20 ° to 45 °. It should be noted that the ridgelines formed by the tapered entry guide portions 103a and 103b flat portion 106 and the inner diameter side tapered entry guide portions 107 are rounded by a common sense so as not to have a sharp edge.

内側継手部材９１は、図１と図３に示すように、ボス部１０８と、このボス部１０８から径方向に沿って突設される３本の脚軸１０９（周方向に沿って１２０度ピッチで配設される）とを備えたトリポード部材からなる。ボス部１０８の中心孔の内径面には雌スプライン１１０が設けられ、シャフト６０の軸部材６６の先端細径部６９の雄スプライン６８がボス部１０８の中心孔に嵌入され、雌スプライン１１０に嵌合する。また、雄スプライン６８のロール側端部には軸部材６６の抜け防止用の止め輪１１１が装着されている。   As shown in FIGS. 1 and 3, the inner joint member 91 includes a boss portion 108, and three leg shafts 109 projecting along the radial direction from the boss portion 108 (120-degree pitch along the circumferential direction). It is comprised of a tripod member provided with. A female spline 110 is provided on the inner diameter surface of the center hole of the boss portion 108, and the male spline 68 of the tip small-diameter portion 69 of the shaft member 66 of the shaft 60 is fitted into the center hole of the boss portion 108 and fitted into the female spline 110. Match. A retaining ring 111 for preventing the shaft member 66 from coming off is attached to the end of the male spline 68 on the roll side.

また、図４に示すように、脚軸１０９の外径面に一対の対向する切欠部１１２，１１２を形成して、この脚軸１０９の断面形状を長円形状としている。この場合、対向する切欠部１１２を非トルク負荷位置に配置するのが好ましい。   As shown in FIG. 4, a pair of opposed notches 112 and 112 are formed on the outer diameter surface of the leg shaft 109, and the cross-sectional shape of the leg shaft 109 is an oval shape. In this case, it is preferable to arrange the opposed notch portions 112 at the non-torque load position.

脚軸１０９には、トルク伝達部材としての球面リング（円環体）１１３が装着されている。すなわち、この球面リング１１３の外径面１１３ａが図３に示すように、ローラ案内面１０２の凹曲面に対応して凸曲面とされている。なお、脚軸１０９の先端部には、球面リング１１３の抜け止め用の止め輪１１４が装着されている。   A spherical ring (annular body) 113 as a torque transmission member is attached to the leg shaft 109. That is, the outer diameter surface 113a of the spherical ring 113 is a convex curved surface corresponding to the concave curved surface of the roller guide surface 102 as shown in FIG. Note that a retaining ring 114 for retaining the spherical ring 113 is attached to the tip of the leg shaft 109.

ところで、軸部材６６は弾性部材８８にて矢印Ｃ方向に押圧されているので、先端細径部６９の端面１１５が、仕切壁９７の押し当て面１１６に押し当てられることになる。この状態で、内部部品９３が外側継手部材９０の内部部品収容部９４に収容された状態が維持される。   Incidentally, since the shaft member 66 is pressed in the direction of the arrow C by the elastic member 88, the end surface 115 of the tip small diameter portion 69 is pressed against the pressing surface 116 of the partition wall 97. In this state, the state where the internal component 93 is accommodated in the internal component accommodating portion 94 of the outer joint member 90 is maintained.

分配器側の継手６１は、ロール側の継手６３と同様の構造となっている。このため、ロール側の継手６３と同一構成については、同一の符号を付してそれらの説明を省略する。この継手６１においても、弾性部材８８の反力で軸部材６５の端面１１５が、仕切壁９７の押し当て面１１６に押し当てられることになる。   The distributor-side joint 61 has the same structure as the roll-side joint 63. For this reason, about the same structure as the roll side coupling 63, the same code | symbol is attached | subjected and those description is abbreviate | omitted. Also in the joint 61, the end surface 115 of the shaft member 65 is pressed against the pressing surface 116 of the partition wall 97 by the reaction force of the elastic member 88.

ところで、この種のローラレベラ５２は、図１０と図１１に示すように、複数のロール６２を備えるものである。図１０と図１１では、１３個（本）のロールを上下千鳥状に配設され、上段には６本のロール６２が配置されるとともに、下段には７本のロール６２が配置されている。このように、本発明に係る駆動力伝達構造に連結されるロール６２は、図示省略の駆動手段からの回転駆動力がこの駆動力伝達構造を介して伝達されて、回転駆動することになって、図１７と図１８に示すように、鋼板等の被矯正材を矯正することができる。なお、この装置（レベラー）の駆動中（運転中）は各ロール６２側が上下に移動するため、継手６３、６１が作動角をとることになる。   By the way, this kind of roller leveler 52 includes a plurality of rolls 62 as shown in FIGS. In FIG. 10 and FIG. 11, 13 (book) rolls are arranged in a staggered manner, with six rolls 62 arranged on the upper stage and seven rolls 62 arranged on the lower stage. . Thus, the roll 62 connected to the driving force transmission structure according to the present invention is rotationally driven by the rotational driving force from the driving means (not shown) being transmitted through the driving force transmission structure. As shown in FIGS. 17 and 18, a material to be corrected such as a steel plate can be corrected. In addition, during the driving (during operation) of the device (leveler), each roll 62 side moves up and down, so that the joints 63 and 61 take an operating angle.

ローラレベラ５２の各ロール６２を交換する必要があり、この交換には図１１と図１２に示す交換用装置１５０が使用される。交換用装置１５０は、上段のシャフト６０を支持する第１支持部材１５１と、下段のシャフト６０を支持する第２支持部材１５２と、第１支持部材１５１をシャフト６０の軸方向に沿って矢印Ｃ、Ｄ方向（図１１及び図１３参照）に往復動させる第１駆動機構１５３と、第２支持部材１５２をシャフト６０の軸方向に沿って矢印Ｃ、Ｄ方向に往復動させる第２駆動機構１５４と、第１支持部材１５１を矢印Ｅ、Ｆ方向（図１４及び図１２参照）（上下方向）に往復動させる第３駆動機構１５５と、第２支持部材１５２を矢印Ｅ、Ｆ方向（上下方向）に往復動させる第４駆動機構１５６とを備える。   It is necessary to replace each roll 62 of the roller leveler 52, and the replacement device 150 shown in FIGS. 11 and 12 is used for this replacement. The replacement device 150 includes a first support member 151 that supports the upper shaft 60, a second support member 152 that supports the lower shaft 60, and an arrow C along the axial direction of the shaft 60. , A first drive mechanism 153 that reciprocates in the D direction (see FIGS. 11 and 13), and a second drive mechanism 154 that reciprocates the second support member 152 in the directions of arrows C and D along the axial direction of the shaft 60. A third drive mechanism 155 that reciprocates the first support member 151 in the directions of arrows E and F (see FIGS. 14 and 12) (vertical direction), and the second support member 152 in the directions of arrows E and F (vertical direction). And a fourth drive mechanism 156 that reciprocates.

第１支持部材１５１は、本体バー１６０と、この本体バー１６０から突設される複数の支持アーム１６１とを備える。また、支持アーム１６１は、棒状のアーム本体１６１ａと、このアーム本体１６１ａの先端に設けられる嵌合部１６１ｂとからなる。嵌合部１６１ｂは半円筒体からなり、シャフト６０側に開口している。   The first support member 151 includes a main body bar 160 and a plurality of support arms 161 protruding from the main body bar 160. The support arm 161 includes a rod-shaped arm main body 161a and a fitting portion 161b provided at the tip of the arm main body 161a. The fitting part 161b consists of a semi-cylindrical body, and is open to the shaft 60 side.

また、第２支持部材１５２は、前記第１支持部材１５１と同様、本体バー１６２と、この本体バー１６２から突設される複数の支持アーム１６３とを備える。また、支持アーム１６３は、棒状のアーム本体１６３ａと、このアーム本体１６３ａの先端に設けられる嵌合部１６３ｂとからなる。嵌合部１６３ｂは半円筒体からなり、シャフト６０側に開口している。なお、第１支持部材１５１の本体バー１６０には、第２支持部材１５２の支持アーム１６１が挿通される貫通孔１６４が設けられている。   Similarly to the first support member 151, the second support member 152 includes a main body bar 162 and a plurality of support arms 163 projecting from the main body bar 162. The support arm 163 includes a rod-shaped arm main body 163a and a fitting portion 163b provided at the tip of the arm main body 163a. The fitting part 163b consists of a semi-cylindrical body, and is open to the shaft 60 side. The main body bar 160 of the first support member 151 is provided with a through hole 164 through which the support arm 161 of the second support member 152 is inserted.

各支持部材１５１、１５２の支持アーム１６１、１６３の嵌合部１６３ａ、１６３ｂがシャフト６０の小径部８５に嵌合可能となっている。すなわち、嵌合部１６３ａ、１６３ｂの幅寸法Ｗを、シャフト６０の小径部８５の軸方向長さＬよりも僅かに小さく設定するとともに、嵌合部１６３ａ、１６３ｂの内径面の曲率半径をシャフト６０の小径部８５の曲率半径と略同一に設定している。   The fitting portions 163 a and 163 b of the support arms 161 and 163 of the support members 151 and 152 can be fitted to the small diameter portion 85 of the shaft 60. That is, the width dimension W of the fitting portions 163a and 163b is set slightly smaller than the axial length L of the small diameter portion 85 of the shaft 60, and the radius of curvature of the inner diameter surface of the fitting portions 163a and 163b is set to the shaft 60. The radius of curvature of the small-diameter portion 85 is set to be approximately the same.

駆動機構１５３、１５４、１５５、１５６は、例えば、油圧ジャッキー等のアクチュエータ１５３Ａ、１５４Ａ、１５５Ａ、１５６Ａにて構成できる。すなわち、図１１に示す状態から第１駆動機構１５３及び第２駆動機構１５４のアクチュエータ１５３Ａ、１５４Ａのロッド１７０、１７０を、図１３に示すように、縮めることによって、嵌合部１６３ａ、１６３ｂが大径基端部８４の小径部側端縁に係止してシャフト６０を図１３に示す矢印Ｄ方向に移動させることができる。また、図１３に示す状態から第１駆動機構１５３及び第２駆動機構１５４のアクチュエータ１５３Ａ、１５４Ａのロッド１７０、１７０を、図１１に示すように、延ばすことによって、大径先端部８３の小径部側端縁に係止してシャフト６０を図１３に示す矢印Ｃ方向に移動させることができる。   The drive mechanisms 153, 154, 155, and 156 can be configured by actuators 153A, 154A, 155A, and 156A such as hydraulic jackies, for example. That is, when the rods 170 and 170 of the actuators 153A and 154A of the first drive mechanism 153 and the second drive mechanism 154 are contracted as shown in FIG. 13 from the state shown in FIG. 11, the fitting portions 163a and 163b become large. The shaft 60 can be moved in the direction of arrow D shown in FIG. 13 by being engaged with the edge on the small diameter side of the diameter base end 84. In addition, by extending the rods 170, 170 of the actuators 153A, 154A of the first drive mechanism 153 and the second drive mechanism 154 from the state shown in FIG. 13, as shown in FIG. The shaft 60 can be moved in the direction of arrow C shown in FIG.

次に前記のように構成された駆動力伝達構造において、ロール６２の交換方法を説明する。まず、図１１と図１２に示すように、嵌合部１６３ａ、１６３ｂがシャフト６０に嵌合しない状態としておく。すなわち、第１駆動機構１５３及び第２駆動機構１５４のアクチュエータ１５３Ａ、１５４Ａのロッド１７０、１７０を図１１に示すように延ばした状態とするとともに、第３駆動機構１５５及び第４駆動機構１５６のアクチュエータ１５５Ａ、１５６Ａのロッド１７１、１７１を縮めた状態としておく。この状態では、交換用装置１５０がシャフト６０に接触せず、回転力駆動機能には影響を及ぼさない。   Next, a method for replacing the roll 62 in the driving force transmission structure configured as described above will be described. First, as shown in FIGS. 11 and 12, the fitting portions 163 a and 163 b are not fitted to the shaft 60. That is, the rods 170, 170 of the actuators 153A, 154A of the first drive mechanism 153 and the second drive mechanism 154 are extended as shown in FIG. 11, and the actuators of the third drive mechanism 155 and the fourth drive mechanism 156 are set. The rods 171 and 171 of 155A and 156A are kept in a contracted state. In this state, the replacement device 150 does not contact the shaft 60 and does not affect the rotational force driving function.

この状態から、図１４に示すように、第３駆動機構１５５及び第４駆動機構１５６のアクチュエータ１５５Ａ、１５６Ａのロッド１７１、１７１を延ばし、嵌合部１６３ａ、１６３ｂにてシャフト６０の小径部８５を嵌合した状態とする。この状態で、第１駆動機構１５３及び第２駆動機構１５４のアクチュエータ１５３Ａ、１５４Ａのロッド１７０、１７０を図１３に示すように縮める。   From this state, as shown in FIG. 14, the rods 171 and 171 of the actuators 155A and 156A of the third drive mechanism 155 and the fourth drive mechanism 156 are extended, and the small diameter portion 85 of the shaft 60 is moved by the fitting portions 163a and 163b. Assume a fitted state. In this state, the rods 170 and 170 of the actuators 153A and 154A of the first drive mechanism 153 and the second drive mechanism 154 are contracted as shown in FIG.

これによって、シャフト６０の第２部材７２は弾性部材８８の弾発力を抗して矢印Ｄ方向にスライドする。この際、第２部材７２はその雄スプライン８６が第１部材７１の雌スプライン７４に嵌合しているので、雌スプライン７４にガイドされて軸心に沿ってスライドする。これによって、図１３に示すように、継手６３の内部部品９３が外側継手部材９０の内部部品収容部９４から抜け出る。すなわち、外側継手部材９０が付設された状態で全ロール６２がこの駆動力伝達構造から分離される。このため、多数のロールを備えたローラレベラであっても、一度にシャフト側とロール側とを分離することができる。   As a result, the second member 72 of the shaft 60 slides in the arrow D direction against the elastic force of the elastic member 88. At this time, since the male spline 86 of the second member 72 is fitted to the female spline 74 of the first member 71, the second member 72 is guided by the female spline 74 and slides along the axis. As a result, as shown in FIG. 13, the internal part 93 of the joint 63 comes out of the internal part accommodating portion 94 of the outer joint member 90. That is, all the rolls 62 are separated from the driving force transmission structure with the outer joint member 90 attached. For this reason, even if it is a roller leveler provided with many rolls, a shaft side and a roll side can be isolate | separated at once.

また、新たな又は補修されたロールを取り付ける場合は、まず、新たな又は補修されたロール６２に外側継手部材９０を装着する。次に、図１３に示すように、第１駆動機構１５３及び第２駆動機構１５４のアクチュエータ１５３Ａ、１５４Ａのロッド１７０、１７０を縮めた状態とする。すなわち、弾性部材の弾発付勢力に抗してシャフト６０を外側継手部材９０と反対方向への押圧力を付与した状態で、シャフト側の軸心と、ロール側の軸心とを一致させる。   In addition, when a new or repaired roll is attached, the outer joint member 90 is first mounted on the new or repaired roll 62. Next, as shown in FIG. 13, the rods 170 and 170 of the actuators 153A and 154A of the first drive mechanism 153 and the second drive mechanism 154 are brought into a contracted state. That is, in a state where a pressing force is applied to the shaft 60 in the opposite direction to the outer joint member 90 against the elastic urging force of the elastic member, the shaft side axis and the roll side axis are made to coincide.

この状態から、図１１に示すように、第１駆動機構１５３及び第２駆動機構１５４のアクチュエータ１５３Ａ、１５４Ａのロッド１７０、１７０を延ばして行く。この際、内部部品９３が外側継手部材９０の内部部品収容部９４の開口部に差掛れば、図６や図７等に示すように、柱部１０１にテーパ状侵入ガイド部１０３及び内周側テーパ状侵入部１０７が設けられているので、このテーパ状侵入ガイド部１０３及び内周側テーパ状侵入部１０７によってトルク伝達部材としての球面リング１１３が案内される。このため、球面リング１１３は滑らかにローラ案内面１０２に嵌合することになる。   From this state, as shown in FIG. 11, the rods 170, 170 of the actuators 153A, 154A of the first drive mechanism 153 and the second drive mechanism 154 are extended. At this time, if the internal part 93 reaches the opening of the internal part accommodating part 94 of the outer joint member 90, the tapered intrusion guide part 103 and the inner periphery are formed in the pillar part 101 as shown in FIGS. Since the side tapered intrusion portion 107 is provided, the spherical ring 113 as a torque transmission member is guided by the tapered intrusion guide portion 103 and the inner peripheral side tapered intrusion portion 107. For this reason, the spherical ring 113 is smoothly fitted to the roller guide surface 102.

このように、球面リング１１３がローラ案内面１０２に嵌合した状態で、第３駆動機構１５５及び第４駆動機構１５６のアクチュエータ１５５Ａ、１５６Ａのロッド１７１、１７１を縮め、嵌合部１６１ａ、１６１ｂをシャフト６０から離間させる。これによって、シャフト６０の第２部材７２が弾性部材８８の弾性力に押され、軸部材６６の端面１１５が外側継手部材９０の押し当て面１１６に当接する。また、分配器側の軸部材６５の端面１１５が外側継手部材９０の押し当て面１１６に当接する。このため、この駆動力伝達構造を介して駆動手段の駆動力がロール６２に伝達される。   Thus, in a state where the spherical ring 113 is fitted to the roller guide surface 102, the rods 171 and 171 of the actuators 155A and 156A of the third drive mechanism 155 and the fourth drive mechanism 156 are contracted, and the fitting portions 161a and 161b are moved. Separated from the shaft 60. As a result, the second member 72 of the shaft 60 is pressed by the elastic force of the elastic member 88, and the end surface 115 of the shaft member 66 contacts the pressing surface 116 of the outer joint member 90. Further, the end surface 115 of the distributor-side shaft member 65 contacts the pressing surface 116 of the outer joint member 90. For this reason, the driving force of the driving means is transmitted to the roll 62 through this driving force transmission structure.

本発明によれば、弾性部材８８の弾発付勢力に抗してシャフト６０を外側継手部材９０と反対方向への引き抜き力を付与すれば、外側継手部材９０に収容されている内部部品９３をこの外側継手部材９０から引き抜くことができる。すなわち、多数のロール６２を備えたローラレベラ５２であっても、外側継手部材９０がロール６２に取り付けられた状態で、シャフト側とロール側とを分離することができる。また、外側継手部材９０をロール側に連結しておき、この状態で内部部品９３を外側継手部材９０に収容することができ、一度にシャフト側とロール側とを連結することができる。このため、ローラレベラ５２など多段ロール６２を有する設備に用いれば、ロール交換など段取り替え時、操業停止時間を極めて短縮ができ製品の生産性の向上を図ることができ、有用である。   According to the present invention, if a pulling force in the direction opposite to the outer joint member 90 is applied against the elastic biasing force of the elastic member 88, the internal component 93 accommodated in the outer joint member 90 is provided. The outer joint member 90 can be pulled out. That is, even in the roller leveler 52 including a large number of rolls 62, the shaft side and the roll side can be separated with the outer joint member 90 attached to the roll 62. Further, the outer joint member 90 is connected to the roll side, and the internal component 93 can be accommodated in the outer joint member 90 in this state, and the shaft side and the roll side can be connected at a time. For this reason, if it uses for the facilities which have the multistage rolls 62, such as the roller leveler 52, at the time of setup changes, such as roll exchange, the operation stop time can be extremely shortened and the productivity of the product can be improved, which is useful.

継手６３をトリポード型とすることによって、この継手６３を組み立てる場合、内側継手部材９１と外側継手部材９０とを軸心方向に沿って相対的に接近させていくことによって、外側継手部材９０のローラ案内面１０２にトルク伝達部材９２であるローラがガイドされて、内部部品９３が外側継手部材９０の内部部品収容部９４に収納されていく。また、内側継手部材９１と外側継手部材９０とを軸心方向に沿って相対的に離間させていくことによって、外側継手部材９０のローラ案内面１０２にローラがガイドされて、内部部品９３が外側継手部材９０から引き抜かれる。   When the joint 63 is assembled by making the joint 63 into a tripod type, the inner joint member 91 and the outer joint member 90 are moved relatively close to each other along the axial direction, whereby a roller of the outer joint member 90 is obtained. A roller which is a torque transmission member 92 is guided by the guide surface 102, and the internal component 93 is accommodated in the internal component accommodating portion 94 of the outer joint member 90. Further, by relatively separating the inner joint member 91 and the outer joint member 90 along the axial center direction, the roller is guided to the roller guide surface 102 of the outer joint member 90, and the inner part 93 is moved to the outer side. The joint member 90 is pulled out.

また、外側継手部材９０の内部部品収容部９４の周壁９９に切欠部１００を設けることによって、ロール回転中（運転中）に、この切欠部を介した潤滑油の滴下が可能となって、潤滑性に優れることになる。   Further, by providing the notch 100 in the peripheral wall 99 of the inner part accommodating portion 94 of the outer joint member 90, it is possible to drop the lubricating oil through this notch during the rotation of the roll (during operation). It will be excellent in performance.

外側継手部材９０にテーパ状侵入ガイド部１０３を設けたり、内周側テーパ状侵入部１０７を設けたりすることによって、連結作業性の一層の向上を図ることができる。特に、テーパ状侵入ガイド部１０３を設けることによって、内部部品９３の収容時に、外側継手部材９０のローラ案内面１０２と内部部品９３とにおいて周方向の位相がずれていても、テーパ状侵入ガイド部１０３によって位相が一致するようにガイドされる。すなわち、内部部品９３がテーパ状侵入ガイド部１０３を押し付ける分力でロール６２を自転させて、内部部品９３の内部部品収容部９４への侵入の容易化を図っている。また、柱部１０１の二等辺三角形状部１０４の傾斜辺の成す角度α及び方向に隣り合う柱部１０１、１０１の対向する傾斜辺の成す角度α１を前記したように６０°〜１１０°とするのが好ましい。角度αが６０°未満であったり、角度α１が１１０°を越えたりすれば、二等辺三角形状部１０４の軸方向長さが大きくなって、コンパクトを阻害するとともに、強度的に劣ることになる。また、角度αが１１０°を越えたり、角度α１が６０°未満であれば、鈍角になり過ぎて内部部品９３の滑らか侵入が阻害されるおそれがある。 By providing the outer joint member 90 with the tapered intrusion guide portion 103 or the inner peripheral side tapered intrusion portion 107, the connection workability can be further improved. In particular, by providing the tapered intrusion guide portion 103, even when the roller guide surface 102 of the outer joint member 90 and the internal component 93 are out of phase in the circumferential direction when the internal component 93 is accommodated, the tapered intrusion guide portion is provided. 103 is guided so that the phases match. In other words, the roll 62 is rotated by a component force by which the internal component 93 presses the tapered intrusion guide portion 103 to facilitate the intrusion of the internal component 93 into the internal component accommodating portion 94. Further, the angle α formed by the inclined sides of the isosceles triangular portion 104 of the column portion 101 and the angle α1 formed by the inclined sides facing each other of the column portions 101 and 101 adjacent in the direction are set to 60 ° to 110 ° as described above. Is preferred. If the angle α is less than 60 ° or the angle α1 exceeds 110 °, the axial length of the isosceles triangular portion 104 becomes large, which impairs compactness and is inferior in strength. . Further, if the angle α exceeds 110 ° or the angle α1 is less than 60 °, the angle α becomes too obtuse and the smooth penetration of the internal part 93 may be hindered.

内周側テーパ状侵入部１０７の傾斜角度γとしては、前記したように、２０°〜４５°とするのが好ましく、第２部１０３ｂの傾斜角度θを２０°〜４５°とするのが好ましい。２０°未満では、傾斜角度γが小さくなり過ぎてガイドとしての機能を発揮できないおそれがある。また、４５°を越えれば、傾斜角度γが大きくなり過ぎて内部部品９３の滑らかな侵入を阻害するおそれがある。なお、２等辺三角形状部１０４の頂点には平坦部１０６が設けられているので、頂点部の損傷を防止できる。 As described above, the inclination angle γ of the inner peripheral tapered entry portion 107 is preferably 20 ° to 45 °, and the inclination angle θ of the second portion 103b is preferably 20 ° to 45 °. . If it is less than 20 °, the inclination angle γ becomes too small and the function as a guide may not be exhibited. On the other hand, if it exceeds 45 °, the inclination angle γ becomes too large, and there is a risk that the smooth intrusion of the internal part 93 may be hindered. In addition, since the flat part 106 is provided in the vertex of the isosceles triangular part 104, damage to a vertex part can be prevented.

トリポード部材の脚軸１０９の断面形状を長円形状（いわゆる小判型形状）とすることによって、潤滑油の内部への侵入（介入）が容易となる。これによって、滑らかなトルク伝達が可能となって、高効率の稼動を長期にわたって安定して行うことができる。しかも、対向する切欠部１１２を非トルク負荷位置に配置されるので、トルク伝達に支障を来たさない。なお、この場合、潤滑油はオイルパンから潤滑させればよい。 By making the cross-sectional shape of the leg shaft 109 of the tripod member into an oval shape (so-called oval shape), it is easy to enter (intervene) the lubricating oil. As a result, smooth torque transmission is possible, and high-efficiency operation can be stably performed over a long period of time. And since the notch part 112 which opposes is arrange | positioned in a non-torque load position, it does not interfere with torque transmission. In this case, the lubricating oil may be lubricated from the oil pan.

次に図１５はテーパ状侵入ガイド部１０３の変形例を示す。すなわち、柱部１０１の開口側を直角三角形状部１７５とし、この直角三角形状部１７５の傾斜辺をこの場合のテーパ状侵入ガイド部１０３としている。また、この直角三角形状部１７５の頂点部には切欠部１７６が設けられている。この際、直角三角形状部１７５の傾斜辺１７５ａの成す角度βを４０°〜６０°とするのが好ましい。 Next, FIG. 15 shows a modification of the tapered intrusion guide portion 103. That is, the opening side of the column part 101 is a right triangle part 175, and the inclined side of the right triangle part 175 is a tapered intrusion guide part 103 in this case. A cutout portion 176 is provided at the apex portion of the right triangle portion 175. At this time, the angle β formed by the inclined side 175a of the right triangle portion 175 is preferably 40 ° to 60 °.

このようなテーパ状侵入ガイド部１０３であっても、内部部品９３の外側継手部材９０の内部部品収容部９４内への侵入をガイドすることができる。また、平坦部１７６が設けられているので、柱部１０１の直角三角形状部１７５の頂点部の損傷を防止できる。 Even such a tapered intrusion guide portion 103 can guide the intrusion of the outer joint member 90 of the inner component 93 into the inner component accommodating portion 94. Further, since the flat portion 176 is provided, damage to the apex portion of the right triangle portion 175 of the column portion 101 can be prevented.

図１６は他の実施形態を示し、この場合、継手６３の外側継手部材９０の反ロール側を円筒状のカバー部材１８０にて外嵌している。すなわち、外側継手部材９０の反ロール側が大径部９０ａとされ、この大径部９０ａにカバー部材１８０を外嵌することによって、切欠部１００を外径側から包囲している。 FIG. 16 shows another embodiment. In this case, the opposite side of the outer joint member 90 of the joint 63 is externally fitted by a cylindrical cover member 180. That is, the non-roll side of the outer joint member 90 is a large-diameter portion 90a, and the cover member 180 is externally fitted to the large-diameter portion 90a to surround the cutout portion 100 from the outer-diameter side.

このため、カバー部材１８０は、ロール側端部に縮径加締部１８０ａを有し、この縮径加締部１８０ａが大径部９０ａの段部に係合している。なお、反ロール側端部には反ロール側に向かって拡開するテーパ部１８０ｂが設けられている。 For this reason, the cover member 180 has a reduced diameter crimped portion 180a at the end on the roll side, and this reduced diameter crimped portion 180a is engaged with the step portion of the large diameter portion 90a. In addition, the taper part 180b which expands toward the anti-roll side is provided in the anti-roll side end part.

このようにカバー部材１８０を付設することによって、潤滑油の敵下を許容できないような設備に適用することができる。この場合、内部部品収容部９４及び脚軸１０９の切欠部１１２、１１２にグリースを充填することになる。運転時の回転数や角度にもよるが、グリースはできるだけ周辺に油分等が飛散しないように、２号または３号ちょう度が好ましく、基油は動粘度１０００ｃｓｔ以上が好ましい。また、オイルを含浸させた発泡ウレタン潤滑剤を使用してもよい。   By attaching the cover member 180 in this way, it can be applied to facilities that cannot tolerate the enemy of the lubricating oil. In this case, the internal component housing portion 94 and the notches 112 and 112 of the leg shaft 109 are filled with grease. Although depending on the number of rotations and angle during operation, grease preferably has a consistency of No. 2 or No. 3 so that oil does not scatter around as much as possible, and the base oil preferably has a kinematic viscosity of 1000 cst or more. Further, a urethane foam lubricant impregnated with oil may be used.

以上、本発明の実施形態につき説明したが、本発明は前記実施形態に限定されることなく種々の変形が可能であって、例えば、継手６３として、トリポード型を使用して、トルク伝達部材として、脚軸１０９に装着される球面リング１１３を使用したが、トリポード型等速自在継手に従来から使用される他の種々のものを使用することができる。すなわち、シングルローラタイプであっても、ダブルローラタイプであってもよく。球面リング１１３の内周と脚軸１０９の外径面との間に針状ころを配置したものであってもよい。実施形態のように、トルク伝達部材として球面リング１１３のみ用いたもの（すなわち、針状ころ等を用いないもの）ではコンパクト化を図る上で有利である。   As described above, the embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, as a joint 63, a tripod type is used as a torque transmission member. The spherical ring 113 attached to the leg shaft 109 is used, but various other types conventionally used for tripod type constant velocity universal joints can be used. That is, it may be a single roller type or a double roller type. A needle roller may be disposed between the inner periphery of the spherical ring 113 and the outer diameter surface of the leg shaft 109. As in the embodiment, using only the spherical ring 113 as a torque transmission member (that is, not using needle rollers or the like) is advantageous in achieving compactness.

また、内部部品９３の脚軸１０９を断面小判型形状とすることによって、潤滑油の介入の容易化を図ったが、断面小判型形状とせずに、ローリングやローレット加工による油溝形成によって、潤滑油の介入の容易化を図ってもよい。また、耐久性確保のため外側継手部材９０や内側継手部材９１およびトルク伝達部材９２は焼入れ焼戻しによって表面をＨＲｃ５８以上に硬化しているが、耐磨耗性向上など必要に応じて窒化処理を行ってもよい。   In addition, the intervention of the lubricating oil has been facilitated by making the leg shaft 109 of the internal part 93 into an oval cross-sectional shape, but without using the oval cross-sectional shape, lubrication is achieved by forming oil grooves by rolling or knurling. Oil intervention may be facilitated. In addition, the outer joint member 90, the inner joint member 91, and the torque transmission member 92 have their surfaces hardened to HRc 58 or higher by quenching and tempering to ensure durability, but nitriding treatment is performed as necessary to improve wear resistance. May be.

なお、ローラレベラとしてのロール６２の数は任意に設定できる。駆動力伝達構造として、ローラレベラに限るものではなく、電縫管製造設備等の成形ロール、鋼板表面処理ラインのスクラバーブラッシロール等の多段のロール等にも適用できる。また、交換用装置１５０は、図１１等に示すものに限らず、駆動機構としても、油圧ジャッキーに限るものではなく、他の種々の往復動機構を用いることができる。しかしながら、図１１と図１２等に示す交換用装置１５０を使用することによって、上下千鳥状に配設される多数のロール６２の分離・連結作業を一度に行える利点がある。 In addition, the number of the rolls 62 as a roller leveler can be set arbitrarily. The driving force transmission structure is not limited to the roller leveler, but can also be applied to a multi-stage roll such as a forming roll of an electric sewing tube manufacturing facility, a scrubber brush roll of a steel sheet surface treatment line, or the like. Further, the replacement device 150 is not limited to the one shown in FIG. 11 and the like, and the drive mechanism is not limited to the hydraulic jacky, and other various reciprocating mechanisms can be used. However, by using the replacement device 150 shown in FIGS. 11 and 12, etc., there is an advantage that a large number of rolls 62 arranged in a staggered manner can be separated and connected at a time.
