PULLEY ABRASION MEASURING APPARATUS AND MEASURING METHOD

To provide a pulley abrasion measuring apparatus and measuring method capable of accurately and easily measuring the abrasion degree of a V-groove of a pulley.SOLUTION: A pulley abrasion measuring apparatus 1 includes: a shaft portion 30: a slender first measurement piece 35 in which one side is fixed to the shaft portion 30 rotatably and the other-side end is brought into contact with the one-side lateral surface of a V-groove; and a slender second measurement piece 45 in which one side is fixed to the shaft portion 30 rotatably and the other-side end is brought into contact with the other-side lateral surface of the V-groove. The pulley abrasion measuring apparatus 1 has a scale 89 for specifying a tensile amount. By using the tensile amount, the rotation angle of the second measurement piece 45 with respect to the first measurement piece 35 when the other-side end of the first measurement piece 35 is in contact with the one-side lateral surface and the other-side end of the second measurement piece 45 is in contact with the other-side lateral surface can be calculated.SELECTED DRAWING: Figure 1 【課題】プーリのＶ溝の摩耗度合を正確かつ容易に測定できるプーリ摩耗測定装置及び測定方法を提供すること。【解決手段】プーリ摩耗測定装置１が、軸部３０と、一方側が軸部３０に対して回転可能に固定され、他方側端部をＶ溝の一方側側面に接触させる細長い第１測定片３５と、一方側が軸部３０に対して回転可能に固定され、他方側端部をＶ溝の他方側側面に接触させる細長い第２測定片４５を備えるようにする。プーリ摩耗測定装置１が、第１測定片３５の他方側端部が一方側側面に接触し、第２測定片４５の他方側端部が他方側側面に接触している際の第１測定片３５に対する第２測定片４５の回転角度を算出可能な引張量を特定するための目盛８９を備えるようにする。【選択図】図１
