Introduction to the Lubrication Life Prediction Project at NSK

～Lubrication Pentagon Theory for the Optimal Design of Rolling Bearings～

発表者：

Taisuke Maruyama

概要： 

To achieve both further reduction of torque and extended life of rolling bearings, NSK is deriving a theoretical formula to predict the time until oil film collapse in the EHD contacts (i.e., Lubrication life).  In this invited lecture, an overview of the lubrication life prediction project launched by NSK will be presented.

一般公演タイトル：

Application of Dielectric Spectroscopy to Lubricant Degradation Diagnosis

発表者：

Shunsuke Iwase

概要：

Dielectric spectroscopy is a method for evaluating the dynamics of polar molecules by analyzing the relaxation behavior of dipoles under an external electric field. This study investigates the dielectric relaxation behavior of oxidatively degraded lubricants and outlines a direction for its application to lubricant degradation diagnostics.
