Abstract
(EN)
Provided are a method of testing rubber wear and a method of calculating the rubber index using the method, capable of accurately duplicating in a sample a wear phenomenon occurring in a tire. The method of testing rubber wear estimates the wear resistance of a tire using the same test piece of rubber as a tire tread and is carried out by pressing a disc-shaped sample (3) to the outer periphery of a disc-shaped abrasive wheel (1) while rotating the sample (3) and the abrasive wheel (1) at separate predetermined speeds of revolutions. A pressing load is applied such that the contact pressure of pressing the sample (3) to the outer periphery of the abrasive wheel (1) becomes the same as the contact pressure of the portion of the tread relating to the evaluation of rubber wear.

L'invention concerne un procédé pour tester l'usure du caoutchouc, et une méthode de calcul de l'indice de caoutchouc basée sur ce procédé, capables de reproduire avec précision dans un échantillon un phénomène d'usure se produisant dans un pneu. Le procédé d'essai estime la résistance à l'usure d'un pneu en utilisant comme éprouvette le même caoutchouc que celui d'une bande de roulement, et est mis en œuvre en comprimant une éprouvette en forme de disque (3) sur la périphérie extérieure d'une roue abrasive en forme de disque (1) tout en faisant tourner l'éprouvette (3) et la roue abrasive (1) à des vitesses de rotation prédéterminées distinctes. Une charge de compression est appliquée de telle sorte que la pression de contact entre l'éprouvette (3) et la périphérie extérieure de la roue abrasive (1) soit égale à la pression de contact de la partie de la bande de roulement, en vue d'évaluer l'usure du caoutchouc.

 タイヤで起きている摩耗現象を精度良くサンプルで再現することが可能なゴム摩耗試験方法及びそれを用いたゴムインデックス算出方法を提供する。 タイヤの耐摩耗をタイヤトレッドと同一ゴム試験片を用いて予測する試験方法であって、円盤状のサンプル3と円盤状の研磨ホイール1とを、それぞれ独立して定められた回転数で回転させながら、サンプル3を研磨ホイール1の外周面に押し付けることにより行うゴム摩耗試験方法である。サンプル3を研磨ホイール1の外周面に押し付ける接地圧が、トレッドのゴム摩耗の評価に係る部位の接地圧と同一になるように押付荷重を加える。
