Study on Influence of Manufacturing Errors on Performance of Spindle Hydrostatic Bearing in Precision Machine Tool

  • 摘要: 分析了精密机床主轴静压轴承节流器孔径d0、轴承半径间隙h0、油腔长度L和油腔宽度B等参数的制造误差,选取了制造误差影响较大的节流孔径d0和半径间隙h0作为分析的对象;建立了考虑节流孔径误差εd和半径间隙误差εh的静压轴承性能计算模型,计算分析了εdεh影响下的轴承刚度J和回转精度e,并通过试验对理论分析结果进行了验证。研究结果表明:制造误差εdεhJ的影响随载荷W的增加而增大,W为600 N、εd为0.05 mm时的J值是εd为−0.05 mm时的1.34倍,εh为10 μm时的J值仅为εh为−10 μm时的29.9%;对于eεd会带来1 μm左右的影响,εh会带来2 μm左右的影响。
