20901 シール軸受のシール機能モデル(OS4 機構デバイスとトライボロジー)

概要

論文の詳細を見る
The sealed bearings are widely used in many applications such as automobiles, electric motors and industrial machinery because of very easy handling. Usually, the sealed bearings are used with grease lubrication. The purposes of a seal are prevention of grease leakage and prevention of contamination from the outside. As one of functional models of seals, the author formulates differential equations for grease leakage from sealed bearing. The leakage model contains two parameters that are associated with a transfer rate from effective space to moving one and a correction factor of film thickness. These two parameters are determined by curve fitting methods. Accordingly, the proposed theory agrees well with the experimental result of the amount of grease leakage versus time.
