Abstract

We present the results of a study of a model rolling tribosystem with ceramic balls making a point “ceramic–steel” contact with a flat movable thrust ring under dry rolling friction and under lubrication. The results of laboratory tribotechnical tests enabled a comparative assessment of the wear rate of hybrid “steel–ceramics–steel” model rolling tribosystems with balls made of different ceramic materials. We ranked the studied material in terms of efficiency and improved the technology of rolling elements for hybrid ball bearings. We manufactured prototype hybrid bearings that undergo bench durability tests.

不同润滑条件下陶瓷-钢混合对的滚动摩擦

摘要

我们介绍了一个模型摩擦摩擦系统的研究结果，该摩擦系统的陶瓷球在干式滚动摩擦和润滑条件下与平坦的可移动止推环形成点“陶瓷-钢”接触。实验室摩擦技术测试的结果可比较评估由不同陶瓷材料制成的球的“钢-陶瓷-钢”混合滚动摩擦系统的磨损率。我们根据效率对研究材料进行排名，并改进了混合球轴承的滚动元件技术。我们制造了经过台架耐久性测试的混合轴承原型。
