摘要
对精密机床气体轴承静特性进行理论分析,运用有限元法将雷诺方程离散化,得到静压气体轴承的承载能力、刚度以及供气量的计算公式。对某精密机床小孔节流静压气体轴承的静态特性进行分析,得到供气压力、偏心率、节流孔直径和刚度以及承载能力之间的关系曲线;通过优化分析,得到精密机床主轴前后静压气体轴承优化的结构参数和操作参数。
The static characteristics of gas bearing for the precision machine tool were analyzed in theory, the Reynolds equation was discretized with the finite element method and the calculating formula of bearing capacity, stiffness and the amount of gas supply were got. The static characteristics of aerostatic bearing with orifice compensated for a precision machine tool were analyzed, the relation curves of gas supply pressure, eccentricity, orifice diameter stiffness and bearing capacity were got. By optimization analysis, the structure and operation parameters of aerostatic bearing for precision machine tool spindle were concluded.
