【0001】0001
本考案は、軸を他の構成部材に連結する軸継手に関するものである。 The present invention relates to a shaft coupling that connects a shaft to other components.
【0002】0002
従来、軸と他の構成部材とを連結する場合、他の構成部材の内面に軸線方向に 平行にキー溝を設け、また他の構成部材に連結する軸にもキー溝を形成しておき 、軸のキー溝にキーを嵌合させた状態で、他の構成部材に対して角度を合わせて 軸から半径方向外方に突出するキー部分を軸継手のキー溝に挿入することにより 、軸と他の構成部材を回転不能に連結し、他の構成部材のキー溝に対応する位置 で半径方向にキー溝まで貫通する止めねじを閉め込むことにより軸と他の構成部 材との軸線方向の相対移動を阻止するようにしていた。 Conventionally, when connecting a shaft to another component, a A keyway is provided in parallel, and a keyway is also formed on the shaft that connects to other components. , with the key fitted in the keyway of the shaft, align it with the other components. By inserting the key part that protrudes radially outward from the shaft into the keyway of the shaft coupling. , a position that non-rotatably connects the shaft and other components and corresponds to the keyway of the other component. The shaft and other components are tightened by tightening the setscrew that passes radially into the keyway. It was designed to prevent relative movement in the axial direction with the material.
【0003】0003
しかし、このような従来の軸と他の構成部材との連結の場合、他の構成部材に 連結する軸自身にもキー溝を形成しなければならず、他の構成部材側のキー溝及 び軸端部のキー溝とキー自身がクリアランスなく嵌合しないと、ガタつきや偏心 を生ずるという不具合が発生する。また他の構成部材側のキー溝と軸端部側のキ ー溝を整合させるという角度合わせをして組み合わせる必要があり、組み立てが 面倒である。 However, in the case of such a conventional connection between the shaft and other components, A keyway must be formed on the shaft itself to be connected, and the keyway and keyway on other component parts must be formed. If the key groove at the end of the shaft and the key itself do not fit without clearance, looseness or eccentricity may occur. This causes a problem that occurs. Also, the keyway on the other component side and the keyway on the shaft end side. - It is necessary to assemble the grooves by adjusting the angle, which makes assembly difficult. It's a hassle.
【0004】 従って、本考案の目的は、組み立てが面倒なキーを使用しないキーレス軸継手 手を得るにある。0004 Therefore, the purpose of this invention is to create a keyless shaft coupling that does not require a key, which is difficult to assemble. It's up to you to get your hands on it.

A plurality of arrayed bolt insertion holes are provided, and bolt connection means are provided on both sides of the elastic cylindrical body. The spacer rings are connected to each other and compressed in the axial direction of the elastic cylindrical body. It is characterized by having a configuration in which:
【0006】[0006]
本考案のこの構成によれば、ボルト連結手段により弾性円筒体の両側のスペー サリングを互いに連結し、スペーサリング間で弾性円筒体の軸線方向に圧縮する ことにより、弾性円筒体が半径方向外方に膨張し、かつ半径方向内方に収縮し、 弾性円筒体を軸及び他の構成部材の双方に強固に摩擦掛合することにより軸と他 の構成部材を強固に連結する。 According to this configuration of the present invention, the space on both sides of the elastic cylindrical body is The spacer rings are connected to each other and compressed in the axial direction of the elastic cylinder between the spacer rings. As a result, the elastic cylinder expands radially outward and contracts radially inward, By firmly engaging the elastic cylinder with both the shaft and other components, the shaft and other components to firmly connect the structural members of the
