摘要
文章分析了液体静压支承传统的静态性能表达式存在的严重缺陷及其产生原因 ,提出了新的静态性能表达式。这种新的静态性能表达式精确地表达了外加载荷与轴承间隙之间的非线性关系 ,真实地反映了支承的静态性能。新的静态性能通用表达式可表达各种传统节流器与新型可变节流器节流时支承的主要静态性能 ,很有应用价值。新的静态性能表达式只有一个变量即外加载荷与油垫推力比 ,故可在支承节流与尺寸参数未确定之前知道支承的主要静态性能 ,它有利于事先选择与确定支承在应用时的主要性能 ,为正确应用液体静压支承提供了可靠的技术基础。
In this paper, the traditional hydrostatic characteristic formulas of hydrostatic bearing, or slide guide, are analyzed.These formulas aren't used to calculate and design the parameters of hydrostatic bearings due to the innate defects. At the same time, new formulas for hydrostatic characteristic of bearing are presented. Using new formulas to design and calculate the parameters of hydrostatic bearing may got exact results quickly and efficiently, because the new formulas can reflect the nonlinear relation between the static load forced on the axle neck and the bearing clearance.
