Effect of Different Liner Materials on Elastohydrodynamic Lubrication of Oil-water Two-phase Lubricated Rolling Mill Oil Film Bearing

open access: yesJixie chuandong, 2017
Taking the rolling mill oil film bearing as the research object,the model of oil- water two-phase flow of elastohydrodynamic lubrication is established by using with thermal effect of the Reynolds equation. The effects of three common liner materials are

Misalignment-Induced Micro-Elastohydrodynamic Lubrication in Rotary Lip Seals

open access: yesLubricants, 2020
In literature the lubrication of rotary lip seals is explained by hydrodynamic action on a microscopic scale. This theory assumes perfect concentricity between the seal and the shaft which in reality seldomly occurs.

Analysis of vibration characteristic for helical gear under hydrodynamic conditions

open access: yesAdvances in Mechanical Engineering, 2017
Based on the elasto-hydrodynamic lubrication theory, a 2-degree-of-freedom nonlinear dynamic model of helical gears with double-sided film is proposed, in which the minimum film thickness behaves as a function of load parameters, lubricant parameters ...
