Abstract

Bubbly oil lubrication is a type of lubrication method which has a high potential for application. However, the lubricating performance of the bubbly oil has not been thoroughly considered. This paper aims to investigate the lubricating performance of the bubbly oil including generation of the bubbly oil, viscosity characteristics of the bubbly oil and the application study of the bubbly oil lubrication. Due to space limitation, the work is divided into two parts. Part 1 focuses on the generation method of the bubbly oil, observation of the bubbly oil and the measurement of viscosity characteristics under a high shear rate. Part 2 focuses on the application study of the bubbly oil lubrication in high-speed bearing. A generation method for the bubbly oil was proposed by a combination of the dispersed-air method and the pressurized dissolution one. An experiment setup for generating the bubbly oil, an observation system for the bubbly oil and a specially-designed viscometer for the bubbly oil were developed. The research results show that the generation method for the bubbly oil is of high efficiency and stability and the observation system is operational.

高剪切速率下气泡油的润滑性能研究，第一部分:气泡油的产生方法及粘度测量

气泡油润滑是一种极具应用潜力的润滑方式。然而，气泡油的润滑性能并没有得到充分的考虑。本文旨在研究气泡油的润滑性能，包括气泡油的产生、气泡油的粘度特性以及气泡油润滑的应用研究。由于篇幅所限，本文分为两部分。第一部分主要介绍了泡沫油的产生方法、泡沫油的观察和高剪切速率下粘度特性的测量。第二部分重点研究了气泡油润滑在高速轴承中的应用。提出了一种分散空气法和加压溶解法相结合的气泡油生成方法。研制了气泡油生成实验装置、气泡油观测系统和专门设计的气泡油粘度计。研究结果表明，气泡油生成方法高效、稳定，观测系统运行良好。
