中文摘要 | 為使潤滑劑供應順暢及降低軸承之磨損,本文探討利用一撓性襯墊黏著於轉子端面後,補償性盤狀步階推力軸承之彈性靜壓潤滑性能。當彈性膜壓從雷諾型方程解出後,托著用以計算負荷與摩擦損耗性能。為能顯示使用撓性材質襯墊後之軸承特性,上述彈性靜壓軸承數據將與剛性靜壓軸承數據做一比較。 |
英文摘要 | To enable the lubricant supply to be easier and reduce bearing wear and scoring, this study is mainly concerned with the elastohydrostatic lubrication of orifice and capillarycompensated circular step thrust bearings by using an elastic upper pad on the runner surface. The Reynolds-type equation governing the film pressure is derived to modify the local film shape. The elstohydrostatic film pressure, load-carrying capacity and viscous dissipation loss re then evaluated. To show the effect of elastic material layer, the above bearing characteristics are presented with various values of nondimensional elastohydrostatic parameter and inner step radius ratio. |
