Abstract

Five common ball bearing greases were studied using a grease-on-paper test configuration, where the bleeding of greases is described by the dynamics of a driving capillary pressure provided by the paper and its opposing counterpart in the grease matrix. The Washburn-like model for extracting the retaining capillary pressure, determined by the affinity of the oil for the grease matrix, has proven to be applicable for greases made of various type of thickeners and base oils, and can potentially contribute to modelling the bleeding of stationary grease as well as to monitoring the change in bleeding properties of greases in a bearing.

研究滚动轴承中固定油脂渗出的模型配置

摘要

使用纸上润滑脂测试配置研究了五种常见的滚珠轴承润滑脂，其中润滑脂的渗出通过由纸及其在润滑脂基质中的相对对应物提供的驱动毛细管压力的动力学来描述。用于提取毛细管压力的类 Washburn 模型由油对润滑脂基质的亲和力决定，已被证明适用于由各种类型的增稠剂和基础油制成的润滑脂，并可能有助于模拟渗出润滑脂以及监测轴承中润滑脂渗出特性的变化。
