Abstract

To measure oil film thickness in EHD (elastohydrodynamic) contacts, optical interferometry methods have been used for a long time. However, it is difficult to apply them to measurements for practical bearings because visible lights cannot be transmitted through metal bodies. In this study, a novel method for measuring oil film thickness in EHD contacts has been developed by improving an electrical impedance method, which has a possibility to be applied to practical bearings.
