いる回転支持装置に関する。[Detailed Description of the Invention] [Industrial Application Field] Generally, a long body has its axis facing sideways, and its outer circumference is supported by a rotating support and rotated around the axis. If the outer diameter is slightly different in the longitudinal direction or if the axial center is slightly tilted, a step phenomenon in which the object tries to move in the axial direction is likely to occur. Therefore, in the present invention, the elongated body is oriented substantially horizontally with the first axis of the elongated body,
Rotating supports rotatably supported around the axis are disposed at a plurality of locations in the longitudinal direction of the elongate body, and are configured to control movement of the elongate body to one side in the axis direction as the elongate body rotates. The present invention relates to a rotation support device that is provided with a stopper that restricts the rotation by abutting the body.

。Conventionally, in a rotational support device for an elongated body, rotational supports that rotatably support the elongated body are arranged at a plurality of locations in the longitudinal direction of the elongated body. The stopper is simply provided with a blocking surface that abuts the end of the elongated body to prevent movement in one direction in the axial direction.

体から前記ストッパに対して圧接力が働くに伴って、回
転支持体には、前記長尺体を介して前記ストッパからの
反力が働く。この場合、前記長尺体と前記回転支持体と
の間には、前記軸心方向に沿った大きな摩擦力が働く。However, if the movement of the elongated body in one direction in the axial direction as it rotates is regulated by contacting the stopper with the blocking surface of the stopper, the rotational support is A reaction force from the stopper acts on the body via the elongated body. In this case, a large frictional force along the axial direction acts between the elongated body and the rotating support.
その結果、回転支持体の長尺体支持部表面の摩耗が早く
進んで寿命か短くなり、回転支持体を早期に交換しなけ
らばならず、不経済であるという問題があった。As a result, the surface of the elongated body support portion of the rotary support is rapidly worn, resulting in a shortened service life, which requires early replacement of the rotary support, which is uneconomical.
本発明は上記欠点を解消し、長尺体の回転に伴う軸心方
向の一方への移動を、経済性よく阻止できる回転支持装
置を提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a rotation support device that can economically prevent the elongated body from moving in one direction in the axial direction as it rotates.
上記目的を達成するため本発明は、回転支持体には、前
記長尺体を横方向に移動させるに伴って、前記長尺体が
乗り上げて上昇する第１長尺体支持部と第２長尺体支持
部とが、前記軸心を通る垂直面の両側に分散配置され、
前記ストッパを構成するに、前記長尺体に対する接当面
を、前記長尺体の一方側端部が接当した状態で前記スト
ッパに対する近接方向に移動するに伴って横方向に摺動
するカム面に形成されていることを特徴とする。In order to achieve the above-mentioned object, the present invention provides a rotary support that includes a first elongated body support part and a second elongated body support part on which the elongated body rides and rises as the elongated body is moved in the lateral direction. ulnar support parts are distributed on both sides of a vertical plane passing through the axis,
The stopper includes a cam surface that slides in the lateral direction as the elongated body moves toward the stopper with one end of the elongated body in contact with the elongated body. It is characterized by being formed.
つまり、前記歩み現象によって、長尺体は、回転に伴っ
て軸心方向の一方側へ移動してその端部がストッパに接
当し、その接当力が大きくなると、前記カム面によって
前記長尺体にカム面に沿う方向の分力が生じ、前記長尺
体の端部が、前記カム面に沿って横方向に摺動する。In other words, due to the step phenomenon, the elongated body moves to one side in the axial direction as it rotates, and its end comes into contact with the stopper, and when the contact force becomes large, the elongated body is moved by the cam surface to A component force is generated in the elongated body in a direction along the cam surface, and the end portion of the elongated body slides laterally along the cam surface.
そして、前記長尺体は、横方向に摺動するに伴って第１
長尺体支持部と第２長尺体支持部とのうちの一方に自重
に抗して乗り上げ、端部が上昇する。前記長尺体端部が
上昇するに伴って、自重に対する分力か、前記ストッパ
から遠ざかる方向に生じ、回転に伴ってストッパに近接
する方向に長尺体を移動させるようとする力は前記分力
の量だけ減少する。その結果、前記分力によって現象さ

り合って、長尺体端部の位置は安定し、ストッパから前
記回転支持体に働く反力は減少させられ、長尺体に働く
摩擦力は小さくなる。Then, as the elongated body slides in the lateral direction, the first
It rides on one of the elongate body support part and the second elongate body support part against its own weight, and the end part rises. As the end of the elongated body rises, the component force relative to its own weight is generated in the direction away from the stopper, and the force that attempts to move the elongated body in the direction closer to the stopper as it rotates is the component force generated in the direction away from the stopper. reduced by the amount of force. As a result, when the walking force of the elongated body caused by the component force has almost disappeared, the position of the end of the elongated body is stabilized and the reaction force acting from the stopper on the rotating support is reduced. and the frictional force acting on the elongated body becomes smaller.
従って、回転支持体の長尺支持部表面の摩耗が抑制され
、前記長尺体支持部表面の寿命が長くなり、前記表面の
修理をしばしば行なう必要がなくなった。また、新たな
動力を用いることなく、長尺体自身の移動力を利用して
その移動を防止するため、エネルギーが節約でき、さら
に長尺体と回転支持体との間の摩擦で失われる動力も少
なくなって、全体としてのランニングコストを安くする
ことかできた。その結果、長尺体の回転に伴う軸心方向
に一方への移動を、簡単な構造で経済性よく阻止できる
回転支持装置を提供することができた。Therefore, wear on the surface of the elongate support part of the rotary support is suppressed, the life of the elongate support part surface is extended, and it is no longer necessary to frequently repair the surface. In addition, since the moving force of the elongated body itself is used to prevent the movement of the elongated body without using new power, energy can be saved, and the power that would otherwise be lost due to friction between the elongated body and the rotating support body can be saved. As a result, overall running costs were reduced. As a result, it was possible to provide a rotation support device that has a simple structure and can economically prevent the elongated body from moving in one direction in the axial direction as it rotates.
