JP-A-53-107007

解決しようとする問題点は、上記従来のローラー体は、ローラーの軸孔に挿通した支軸の両端部を受枠に軸支するため、両端の軸支間寸法が長くなり、支軸はレールの荷重で変形し易く、ローラー体が円滑に回転されなくなる問題があった。   The problem to be solved is that the above-mentioned conventional roller body supports both ends of the support shaft inserted through the shaft hole of the roller to the receiving frame. The roller body is easily deformed and the roller body is not smoothly rotated.

本考案は、ローラー体の軸方向の長さを短くすることなく、ローラー体の両端部より中心側に偏倚した位置で軸支するようにしてローラー体がレールなどの荷重で円滑な回転を損なうことがない鉄道レールなどを載置するローラー装置を提供するものである。   The present invention impairs smooth rotation of the roller body by a load such as a rail so that the roller body is axially supported at a position biased toward the center side from both ends of the roller body without shortening the axial length of the roller body. The present invention provides a roller device for mounting a railway rail or the like that never happens.

本考案のローラー装置は、軸支孔を貫通した軸支部を上面左右に突設した基板と、この基板の左右軸支部に回動可能に軸支するローラー体とを備え、前記ローラー体は、前記左右軸支部間に回転可能に軸支される中間ローラー部と、前記左右軸支部の外側位置で前記中間ローラー部と結合して同心上で回転可能に軸支される左右一対の外側ローラ−部とにて構成し、前記中間ローラー部の両端面と左右両外側ローラ−部の内側端面とのいずれか一方に前記軸支部の軸支孔に挿通する突軸部と嵌合軸部を突設するとともに他方にこの嵌合軸部を嵌合する嵌合孔を形成し、前記突軸部を軸支部の軸支孔にそれぞれ軸支するとともに前記嵌合軸部を前記嵌合孔にそれぞれ嵌合し、前記中間ローラー部の両端面に左右両外側ローラ−部をねじ部材にて結合したものである。   The roller device according to the present invention includes a substrate having a shaft support portion penetrating the shaft support hole provided on the left and right sides of the upper surface, and a roller body rotatably supported on the left and right shaft support portions of the substrate.

And it can be supported so that the intermediate roller part of a roller body, or the protruding shaft part of both right and left outer roller parts can be smoothly rotated without using a bearing.

さらに、請求項１または２記載のローラー装置において、軸支部を基板と一体にアルミニウムダイキャストにて成形したものである。そして、ローラー装置全体が軽量になり、組み立て部品数が少なくなる。   Furthermore, in the roller device according to claim 1 or 2, the shaft support portion is formed integrally with the substrate by aluminum die casting. And the whole roller apparatus becomes lightweight and the number of assembly parts decreases.

ローラー体10は中間ローラー部11の両端部にて軸支されるため、ローラー体10の両端で軸支した構成に比べ、ローラー体10で受ける例えば鉄道のレール23の荷重で撓み変形し難くなり、ローラー体10は円滑な回転を保持され、しかも、ローラー体10は中間ローラー部11と左右両外側ローラ−部12とによって所定長さを保持することができ、レール23などを安定して支持でき、例えば、レール23を載置する場合、温度変化によってローラー体10が伸縮してもローラー装置を転倒させるようにことがなく、レールの伸縮に確実に対応でき、また、レールの端面を位置を合わせるための移動も容易にできる。   Since the roller body 10 is pivotally supported at both ends of the intermediate roller section 11, the roller body 10 is less likely to bend and deform due to the load of the rail 23 of the railway, for example, compared to the configuration in which the roller body 10 is pivotally supported. The roller body 10 is maintained in a smooth rotation, and the roller body 10 can hold a predetermined length by the intermediate roller portion 11 and the left and right outer roller portions 12, and stably supports the rail 23 and the like. For example, when the rail 23 is placed, even if the roller body 10 expands / contracts due to a temperature change, the roller device does not fall down, and the rail can be reliably expanded and contracted, and the end surface of the rail is positioned. Easy to move to match.

さらに、軸支部８の軸支孔５に挿通する突軸部14は軸方向の中間部が突出する弧状軸支面16とすることにより、ローラー体10の中間ローラー部11はベアリングを用いなくても円滑に回転される。   Further, the projecting shaft portion 14 inserted into the shaft support hole 5 of the shaft support portion 8 is an arcuate shaft support surface 16 from which an intermediate portion in the axial direction projects, so that the intermediate roller portion 11 of the roller body 10 does not use a bearing. Also rotate smoothly.
