1883年,在英国机械学会上发表了一个轴承摩擦实验的结果。即托尔(BeauchampTower)的实验报告。他对一个直径为100mm、长150mm、弧角为157°炮铜制的滑动轴承,在各种载荷和转速的条件下,测定了摩擦系数,在论文中提出其数值。这个测定数值对当时起到了有益的作用。然而,托尔这一实验对摩擦和润滑史上的贡献,倒不是这个费力的测定值。 In 1883, the results of a bearing friction test were published at the British Society of Mechanical Engineering. BeauchampTower experiment report. He measured the friction coefficient for a sliding bearing of 100 mm diameter, 150 mm long and 157 ° arc gun made of gunmetal under various loads and speeds, and proposed the values ​​in the paper. This measured value played a beneficial role at that time. However, the contribution of Thorr’s experiment to the history of friction and lubrication is not a laborious measurement.
