TUNNEL CARRIAGE WHEEL
To provide a tunnel carriage wheel that allows a tunnel carriage to move smoothly on a standard rail simply installed in a tunnel.SOLUTION: A wheel 2 of the invention is placed on a standard rail 1 and supports a tunnel carriage V so as to be movable along the standard rail 1 with a central portion 14 of a top surface of a head 13 forming a convex curved surface having a relatively large curvature radius R1, and with both side edges 15, 16 of the top surface of the head 13 having relatively small curvature radii R2, R3, respectively. An outer peripheral surface 21 of the wheel 2 is formed to be a concave curved surface having a radius curvature same as the curvature radius R1 of the central portion 14 of the standard rail 1.SELECTED DRAWING: Figure 3
【課題】トンネル内に簡易に設置した規格レール上をトンネル用台車が円滑に移動可能としたトンネル台車用車輪を提供する。【解決手段】頭部１３頂面の中央部１４が相対的に大きい曲率半径Ｒ１の凸曲面をなすとともに頭部１３頂面の両側縁部１５，１６が相対的に小さい曲率半径Ｒ２，Ｒ３の凸曲面をなす規格レール１に載置されてトンネル用台車Ｖを規格レール１に沿って移動可能に支持する車輪２であって、車輪２の外周面２１を、規格レール１の中央部１４の曲率半径Ｒ１と同一曲率半径の凹曲面に成形する【選択図】 図３
