Abstract
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.
