PROBLEM TO BE SOLVED: To provide a wheel shape measurement device which can easily and precisely measure the shape of wheels of a railway vehicle in the circumferential direction, even if the wheel has any peeled scratches on its tread.SOLUTION: A wheel shape measurement device comprises: a wheel center adjuster 1 detachably attached to a wheel 2; a two-dimensional laser displacement sensor 6 to measure the shape of the wheel tread 2b; a roller encoder 7 set on the wheel tread; and an angle adjuster 8 of the displacement sensor 6. The wheel center adjuster comprises two pins 4a and 4b forced to touch the wheel flange 2a and an arm 5 which is set at a central part of the line connecting the two pins and perpendicularly to the line. After the two dimensional laser displacement sensors is attached to the arm and the light emitting part of the two dimensional laser displacement sensors is adjusted to be directed toward the central part by the angle adjuster, the wheel center adjuster is detached from the wheel and, during rotating the wheel, the wheel shape is measured in the circumferential direction using the two dimensional laser displacement sensor and the roller encoder.SELECTED DRAWING: Figure 1

    【課題】鉄道車両等の車輪の円周方向の形状を、車輪の踏面に剥離傷等の小さな凹凸がついている場合であっても、容易かつ精密に測定することができる、車輪の形状測定装置を提供する。【解決手段】車輪2に着脱可能に取り付けられる車輪中心調整器1と、車輪踏面2bの形状を測定する二次元レーザ変位センサ6と、車輪踏面に設置されるローラエンコーダ7と、二次元レーザ変位センサ6の角度調整器8とを備え、車輪中心調整器は、車輪のフランジ2aに当接させる二本のピン4a、4bと、二本のピン間を結ぶ直線の中央部に、前記直線と直交するように設けられたアーム5とを備え、アームに二次元レーザ変位センサを取り付け、二次元レーザ変位センサの発光部が前記中央部を向くように角度調整器により調整した後、車輪中心調整器を車輪から取り外し、車輪を回転させながら二次元レーザ変位センサとローラエンコーダとによって車輪の円周方向の形状を測定する。【選択図】図1
