标准摘要
[中文适用范围]： 该方法的原理是通过测量皮带轮的旋转频率以及直线跨度上的皮带速度或皮带轮之间的中心距离和时间来计算在测试夹具上的皮带轮中运行的皮带的节圆直径。 皮带的旋转，以及有效线差的计算。 [外文原描述]： The principle of the method specified is calculation of the pitch diameter of the belt operating in the pulley on a test fixture by measuring the rotational frequency of the pulley and either the belt velocity over a straight span or the centre distance between the pulleys and the time of rotation of the belt, and calculation of the effective line differential.
英文名称Belt drives — Dynamic test to determine pitch zone location — Part 2: V-ribbed belts
