摘要

本文為定補償和閉式靜壓平面軸承使用可變補償研究，文中討論的雙向可變節流器包括圓柱滑桿節流器，圓錐滑桿節流器，薄膜節流器以及自補償節流器。分析工作壓力比對工作台位移率、承載力，軸承靜剛度之影響，探討不同節流器設計參數對於封閉式靜壓平面軸承靜態特性之影響。因此，根據工作台位移對油腔壓力的最小位移梯度或最大剛度可以得知各節流器最佳的設計參數及油腔壓力的使用範圍。

This thesis of a serial studies for studying constant and variable compensations of the closed-type hydrostatic flat bearing. In this part, the double-action variable restrictors including cylindrical-spool, conical-spool and membrane types and self-compensation are taken into consideration. Analysis of the recess pressure versus displacement ratio of worktable and load capacity and static stiffness. Characteristics of hydrostatic closed-type bearing using double-action compensations. The static stiffness of will be also determined by the same method as shown in previous parts. Consequently, the usage range of recess pressure and optimal parameters of appropriate compensation type can be obtained according to the smallest gradient of displacement or maximum stiffness.
