本文介绍了一种用于研究在赫兹载荷作用下形成平圆接触面的轧制钢表面间力系的试验装置。该装置是用来探索的行为接触机构滚动的润滑剂的存在下，并与表面之间的相对滑动的程度很小。已经观察到从边界到部分弹性流体动力润滑和从部分到几乎完全弹性流体动力润滑的过渡，并且从一种类型的润滑到另一种类型的过渡的特征在于系统的摩擦行为的变化。这些行为变化与接触点上的电导率读数有关，可以看出，接触点上的测量电压与施加电压的比值是表面粗糙接触频率的量度。将比率视为累积分布函数表明存在两个不同的群体，并且从一个群体过渡到另一个群体的点。
In this paper a rig is described for the study of force systems between rolling steel surfaces which under Hertzian load form flat circular contact surfaces. The rig is used to explore the behaviour of contacting bodies rolling in the presence of a lubricant and with a small degree of relative slide between the surfaces. Transitions from boundary to partial elastohydrodynamic lubrication and from partial to almost complete elastohydrodynamic lubrication have been observed and the transition from one type of lubrication to the other is marked by changes in the frictional behaviour of the system. These changes in behaviour are related to conductivity readings taken across the contact and it can be shown that the ratio of measured voltage across the contact to the applied voltage is a measure of the frequency at which surface asperities come into contact. Treating the ratio as a cumulative distribution function shows that two distinct populations exist and the point at which transition from one population to...
