Analysis of thermal expansion effects on leakage in self-sealed journal bearings
摘要
This paper, based on a simplified model, researched the problem of liquid lubricant leakage caused by thermal expansion effects in a self-sealed journal bearing, The analysis indi- cated that mismatch between thermal expansion coefficient of oil-holding-space in bearing, σ_T, and that of liquid lubricant, α_(oi), is a subtle factor inducing leakage when bearing temperature varies. Measures like properly selecting liquid lubricant and carefully designing bearing structure could be taken to reduce the leakage by matching α_T and α_(oil), Several such ideas concerning bearing mate- rial choosing and structure designing were presented.
