摘要

本文介绍了孔板和恒流阀（CFV）节流补偿锥形轴颈轴承在工作速度变化时的轴承性能。利用有限元对不同锥角轴承进行的分析研究体现了不同的轴承特性，如最大压力、最小流体膜厚度、流体流量、刚度、阻尼等。通过求解配合面润滑剂的雷诺方程，获得了工作速度参数范围 Ω = 0.1-1.0 的这些特性。研究表明，随着速度的增加，CFV 锥形轴颈轴承比孔补偿轴承显示出更显著的结果。这将有助于设计师在设计轴承时考虑不同的速度。

Comparison of conical hybrid journal bearing performances for varying speeds

This paper describes the bearing performances of orifice and constant flow valve (CFV) restrictor-compensated conical journal bearings for variations in operating speed. The analytical studies for different cone angle bearings using FEM are represented in terms of different bearing characteristics such as maximum pressure, minimum fluid film thickness, fluid flow, stiffness, damping, and so on. The Reynolds equation for lubricant at the mating surfaces is solved to obtain these characteristics for the operating speed parameter range Ω = 0.1–1.0. The study reveals that the CFV conical journal bearing shows more significant results as the speed progresses than the orifice compensation. This will help the designer design bearings by considering varying speeds.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
