Abstract

A mixture model suitable for studying the thermal effect on elastohydrodynamic lubrication (EHL) of emulsions is proposed. The maximum temperature rise occurs at the emulsion layer because sliding occurs mainly in the emulsion layer to generate shear heating, and it increases with increasing oil concentration, slide-to-roll ratio, mean speed, and load. The rise in surface temperature of the rollers decreases with the increase in the adsorbed layer’s thickness at the entrance. This result indicates that the adsorbed layers insulate the heat flux across the film, so that the surface temperature becomes cooler with a greater thickness of the adsorbed layer.

EHL触头中水包油型乳化液对混合物润滑的热效应

摘要

提出了一种适合研究乳化液弹性动力润滑（EHL）的热效应的混合模型。最大温度升高发生在乳剂层，因为滑动主要发生在乳剂层中以产生剪切加热，并且随着油浓度，滑动比，平均速度和负载的增加而增加。辊表面温度的升高随着入口处吸附层厚度的增加而降低。该结果表明，被吸附的层使穿过膜的热通量绝缘，从而随着被吸附的层的厚度增大，表面温度变得更低。
