Description

The calculation of EHL film thickness is important in rolling bearing design. The film thickness analysis under starved condition requires following two technologise. (a) EHL analysis with prescribed inlet oil distribution. (b) Inlet oil distribution analysis with prescribed oil feed rate for a bearing. There are some studies of (a), but (b) has never been studied. Thus, this paper aims to develop a new method for coupled simulation of micro (EHL) and macro flow (oil flow outside an EHL). The macro flow is modeled as liquid film (LF). The present method is applied to a rolling bearing. The relationship between oil feed rate and oil film thickness is investigated.
