この考案は、圧延機の左右圧下装置間に設ける圧下クラッチ等に用いるクラッ チ付歯車型軸継手に関する。 The present invention relates to a gear type shaft coupling with a clutch used for a reduction clutch or the like provided between left and right reduction devices of a rolling mill.
【0002】[0002]
圧延機の左右圧下装置間に設ける圧下クラッチ等に用いるクラッチ付歯車型軸 継手は、外歯車と内歯車とによって連結するクラッチで、外歯車と内歯車をスラ イドさせることによりクラッチの断続が行われる。 従来のクラッチ付歯車型軸継手は、駆動軸の端部にキーを介して外嵌した内筒 の周面に設けた内歯に噛合う外歯を内周面に設けた外筒のフランジと、被駆動軸 の端部にキーを介して外嵌した内筒の周面に設けた内歯に噛合う外歯を内周面に 設けた外筒のフランジを、それぞれボルトにより結合してなる。 A gear type shaft coupling with a clutch, which is used as a rolling clutch between the left and right rolling mills of a rolling mill, is a clutch that connects an external gear and an internal gear, and the clutch is disengaged by sliding the external gear and the internal gear. Be seen. The conventional gear type shaft coupling with clutch has a flange of an outer cylinder with an outer tooth on the inner surface that meshes with an inner tooth on the outer surface of the inner cylinder that is fitted onto the end of the drive shaft via a key. , The flanges of the outer cylinder having the outer teeth on the inner peripheral surface that mesh with the inner teeth provided on the outer peripheral surface of the inner cylinder fitted onto the end of the driven shaft via a key are respectively connected by bolts. .
【0003】 上記クラッチ付歯車型軸継手のクラッチの断続は、被駆動軸側の外筒の外周に 設けた凹溝に係合するレバーを、シリンダー等により操作して各外筒をスライド させ、被駆動軸側の外筒の外歯と内筒の周面に設けた内歯を噛合わせ、あるいは 被駆動軸側の外筒の外歯と内筒の周面に設けた内歯の噛合わせを解除することに より行われる。 上記従来のクラッチ付歯車型軸継手は、クラッチ切りの状態において、駆動軸 や被駆動軸の軸受のギャップが大きければ、クラッチの自重で駆動軸および被駆 動軸が垂れ下がって軸芯がずれ、クラッチの入り、切り、特に切りから入りへの 操作が容易にできないという問題がある。The clutch of the gear type shaft joint with a clutch is disengaged by operating a lever engaging with a groove provided on the outer circumference of the outer cylinder on the driven shaft side by a cylinder or the like to slide each outer cylinder, The outer teeth of the outer cylinder on the driven shaft side mesh with the inner teeth of the inner cylinder, or the outer teeth of the outer cylinder on the driven shaft side mesh with the inner teeth of the inner cylinder. It is done by canceling. In the above conventional clutch-type gear type shaft coupling, if the gap between the bearings of the drive shaft and the driven shaft is large in the clutch disengaged state, the drive shaft and the driven shaft hang down due to the weight of the clutch, and the shaft center shifts. There is a problem that the operation of engaging and disengaging the clutch, especially from the disengagement to the engagement cannot be performed easily.
【0004】 上記問題を解消するクラッチ付歯車型軸継手としては、図3および図4に示す とおり、駆動軸31の端部に外嵌した内筒32の周面に設けた内歯33に噛合う 外歯34を内周面に設けた外筒35のフランジ36と、被駆動軸37の端部に外 嵌した内筒38の周面に設けた内歯39に噛合う外歯40を内周面に設けた外筒 41のフランジ42を、それぞれボルトにより結合してなるクラッチ付歯車型軸 継手において、各外筒35、41と各内筒32、38間にそれぞれ軸受43、4 4を設けたクラッチ付歯車型軸継手(実開平4−124339号公報)が提案さ れている。なお、45は図示しない切替えレバーが係合する凹溝である。As shown in FIGS. 3 and 4, a gear type shaft coupling with a clutch that solves the above problem is provided with an inner tooth 33 provided on the peripheral surface of an inner cylinder 32 that is externally fitted to the end of the drive shaft 31. A flange 36 of an outer cylinder 35 having matching outer teeth 34 on its inner peripheral surface and an outer tooth 40 meshing with an inner tooth 39 provided on the peripheral surface of an inner cylinder 38 fitted on the end of a driven shaft 37 are internally provided. In the clutch type gear type shaft coupling in which the flanges 42 of the outer cylinder 41 provided on the peripheral surface are respectively coupled by bolts, bearings 43, 44 are respectively provided between the outer cylinders 35, 41 and the inner cylinders 32, 38. A gear type shaft coupling with clutch provided (Japanese Utility Model Laid-Open No. 4-124339) has been proposed. Reference numeral 45 is a concave groove with which a switching lever (not shown) is engaged.

上記実開平4−124339号公報に開示のクラッチ付歯車型軸継手は、各外 筒35、41と各内筒32、38間にそれぞれ軸受43、44を設けるため、各 外筒35、41のスライド量に応じて内筒32、38を長くする必要があり、圧 延機の左右圧下装置間が広くなければ適用することができないという問題があり 、スペース上の制約を受けることとなる。 In the gear type shaft coupling with a clutch disclosed in Japanese Utility Model Laid-Open No. 4-124339, bearings 43 and 44 are provided between the outer cylinders 35 and 41 and the inner cylinders 32 and 38, respectively. It is necessary to lengthen the inner cylinders 32 and 38 according to the amount of slide, and there is a problem that it cannot be applied unless there is a wide space between the left and right rolling down devices of the rolling machine, which limits the space.
【0006】 この考案の目的は、クラッチ付歯車型軸継手において、スペース上の制約を受 けることなく、クラッチの自重による軸芯のずれがなく、クラッチの入り、切り 操作を容易に行うことができるクラッチ付歯車型軸継手を提供することにある。An object of the present invention is to provide a gear type shaft coupling with a clutch, which does not have a space limitation, does not cause a displacement of a shaft center due to a weight of the clutch, and can easily perform a clutch engaging / disengaging operation. It is to provide a gear type shaft coupling with a clutch that can be performed.

本考案者らは、上記目的を達成すべく種々検討を行った。その結果、実開平4 −124339号公報に開示のクラッチ付歯車型軸継手の各外筒と各内筒間の軸 受に替えて、各内筒間に軸受を設けることによって、各外筒のスライド量に応じ て内筒を長くする必要がなく、クラッチ切り時においても駆動軸と被駆動軸の内 筒は、軸受によって支持され、軸芯のずれが防止できるとの結論に到達し、この 考案に想到した。 The present inventors have conducted various studies to achieve the above object. As a result, a bearing is provided between the inner cylinders instead of the bearing between the outer cylinders and the inner cylinders of the gear type shaft coupling with clutch disclosed in Japanese Utility Model Laid-Open No. 4-124339. We reached the conclusion that it is not necessary to lengthen the inner cylinder according to the amount of slide, and the inner cylinders of the drive shaft and driven shaft are supported by bearings even when the clutch is disengaged, and it is possible to prevent shaft misalignment. I came up with the idea.
【0008】 すなわちこの考案は、駆動軸の端部に外嵌した内筒の周面に設けた内歯に噛合 う外歯を内周面に設けた外筒のフランジと、被駆動軸の端部に外嵌した内筒の周 面に設けた内歯に噛合う外歯を内周面に設けた外筒のフランジを、それぞれボル トにより結合してなるクラッチ付歯車型軸継手において、各内筒間に軸受を設け たことを特徴とするクラッチ付歯車型軸継手である。That is, according to the present invention, the flange of the outer cylinder having the outer teeth provided on the inner peripheral surface that meshes with the inner teeth provided on the outer peripheral surface of the inner cylinder externally fitted to the end of the drive shaft, and the end of the driven shaft. In the gear type clutch joint with clutch, in which the flanges of the outer cylinder having the outer teeth meshing with the inner teeth provided on the outer peripheral surface of the inner cylinder fitted to the outer portion are connected by bolts, respectively. A gear-type shaft coupling with a clutch, characterized in that a bearing is provided between the inner cylinders.

この考案においては、各内筒間に軸受を設けたから、クラッチ切りの状態では 被駆動軸の内筒周面の内歯と外筒内周面の外歯が噛合っていないが、被駆動軸の 内筒は駆動軸の内筒に軸受によって支持される。このため、駆動軸と被駆動軸の 軸芯のずれが防止され、クラッチの入り、切り操作を容易に行うことができ、ス ペース上の制約も受けることがない。 なお、各内筒間に設ける軸受としては、各種ベアリングを用いることができ、 また、ベアリングに替えてブッシュを用いることもできる。 In this invention, since the bearings are provided between the inner cylinders, the inner teeth on the inner peripheral surface of the driven shaft do not mesh with the outer teeth on the inner peripheral surface of the outer cylinder when the clutch is disengaged. The inner cylinder of is supported by bearings on the inner cylinder of the drive shaft. Therefore, the displacement of the driving shaft and the driven shaft from each other is prevented, the clutch can be easily engaged and disengaged, and the space is not restricted. Various bearings may be used as the bearings provided between the inner cylinders, and bushes may be used instead of the bearings.

以下にこの考案の詳細を実施の一例を示す図1および図2に基いて説明する。 図1はこの考案のクラッチ付歯車型軸継手のクラッチ入り時の縦断面図、図2は 同じくクラッチ切り時の縦断面図である。 図1および図2において、1は駆動軸で、駆動軸1の端部には、キー2を介し て周面に内歯3を有する内筒4が外嵌されている。5は被駆動軸で、被駆動軸5 の端部には、駆動軸1と同様にキー6を介して周面に内歯7を有する内筒8が外 嵌されている。内筒4の内歯3に噛合う外歯9を内周面に有する外筒10は、内 筒4に外嵌されている。同様に内筒8の内歯7に噛合う外歯11を内周面に有す る外筒12は、内筒8に外嵌されている。 そして内筒4と内筒8の端面には、図示しないボルトによりカートリッジ13 とシャフト14がそれぞれ接続され、ベアリング15を保持している。 また、各外筒10、12の対向面に設けたフランジ16、17は、図示しない ボルトにより接続されている。 The details of this invention will be described below with reference to FIGS. FIG. 1 is a vertical sectional view of a gear type shaft coupling with a clutch of the present invention when the clutch is engaged, and FIG. 2 is a vertical sectional view of the same when the clutch is disengaged. In FIGS. 1 and 2, reference numeral 1 denotes a drive shaft, and an inner cylinder 4 having inner teeth 3 on its peripheral surface is externally fitted to an end of the drive shaft 1 via a key 2. Reference numeral 5 denotes a driven shaft, and an inner cylinder 8 having inner teeth 7 on its peripheral surface is externally fitted to an end portion of the driven shaft 5 via a key 6 like the drive shaft 1. An outer cylinder 10 having outer teeth 9 that mesh with the inner teeth 3 of the inner cylinder 4 on the inner peripheral surface is fitted onto the inner cylinder 4. Similarly, an outer cylinder 12 having outer teeth 11 that mesh with inner teeth 7 of the inner cylinder 8 on the inner peripheral surface is fitted onto the inner cylinder 8. The cartridge 13 and the shaft 14 are connected to the end faces of the inner cylinder 4 and the inner cylinder 8 by bolts (not shown), and hold bearings 15. The flanges 16 and 17 provided on the facing surfaces of the outer cylinders 10 and 12 are connected by bolts (not shown).
【0011】 また、外筒12のフランジ17と反対側周面の凹溝18には、シリンダー等に より操作される図示しないレバーが係合しており、シリンダー等によりレバーを 操作して外筒10、12をスライドさせれば、図1に示すとおり、外筒12の外 歯11と内筒8の内歯7が噛合つてクラッチ入りの状態となり、あるいは図2に 示すとおり、外筒12の外歯11と内筒8の内歯7の噛合わせが解除されてクラ ッチ切りの状態とすることができるよう構成されている。A not-shown lever operated by a cylinder or the like is engaged with a groove 18 on the peripheral surface of the outer cylinder 12 opposite to the flange 17. The lever is operated by the cylinder or the like to operate the outer cylinder. By sliding 10 and 12, as shown in FIG. 1, the outer teeth 11 of the outer cylinder 12 and the inner teeth 7 of the inner cylinder 8 are engaged with each other so that the clutch is engaged, or, as shown in FIG. The outer teeth 11 and the inner teeth 7 of the inner cylinder 8 are disengaged from each other so that the clutch can be cut.
【0012】 上記のとおり構成したから、図1に示すクラッチ入りの状態においては、内筒 8の内歯7と外筒12の外歯11とは噛合っており、内筒8は外筒10の外歯9 と噛合う内筒4の内歯3を介して駆動軸1と共に回転する外筒10に支持され回 転している。また、図2に示すクラッチ切りの状態においては、内筒8の内歯7 と外筒12の外歯11とは噛合っていないが、内筒8はシャフト14、ベアリン グ15およびカートリッジ13を介して駆動軸1と共に回転する内筒4に支持さ れる。Because of the above-described configuration, in the clutch engaged state shown in FIG. 1, the inner teeth 7 of the inner cylinder 8 and the outer teeth 11 of the outer cylinder 12 are meshed with each other, and the inner cylinder 8 is the outer cylinder 10. It is supported and rotated by an outer cylinder 10 that rotates together with the drive shaft 1 via inner teeth 3 of an inner cylinder 4 that meshes with the outer teeth 9 of FIG. Further, in the clutch disengaged state shown in FIG. 2, the inner teeth 7 of the inner cylinder 8 and the outer teeth 11 of the outer cylinder 12 are not meshed with each other, but the inner cylinder 8 includes the shaft 14, the bearing 15, and the cartridge 13. It is supported by the inner cylinder 4 that rotates together with the drive shaft 1.
【0013】 したがって、図2に示すクラッチ切りの状態においても、被駆動軸5は、先端 に外嵌した内筒8がシャフト14、ベアリング15およびカートリッジ13を介 して駆動軸1と共に回転する内筒4に支持されているから、駆動軸1の内筒4と 被駆動軸5の内筒8の軸芯のずれが防止され、クラッチの入り、切りを容易に行 うことができる。 なお、内筒4、8との間に軸受としてベアリング15を用いたが、ブッシュを 用いることもできる。Therefore, even in the clutch disengaged state shown in FIG. 2, the driven shaft 5 has an inner cylinder 8 externally fitted to the tip thereof which rotates together with the drive shaft 1 via the shaft 14, the bearing 15 and the cartridge 13. Since it is supported by the cylinder 4, the inner cylinder 4 of the drive shaft 1 and the inner cylinder 8 of the driven shaft 5 are prevented from being displaced from each other, and the clutch can be easily engaged and disengaged. Although the bearing 15 is used as a bearing between the inner cylinders 4 and 8, a bush may be used.
