油腔结构对高速动静压轴承性能的影响(英文)

Different Geometric Configurations Research of High Speed Hybrid Bearings

研究了四种不同油腔形状的高速液体动静压轴承。研究内容包括轴承润滑油流量、承载能力、刚度、涡动频率。这四种油腔结构轴承分别是正方形油腔 ,三角形油腔、圆形油腔、角向小孔轴承。通过对这四种轴承性能比较出现 ,角向小孔轴承具有最优良的性能。

In this paper,four hybrid bearings having different geometric configurations were analyses for their static and dynamic characteristics,including flow rate,load capacity,stiffness,and whirl frequency ratio.The four bearings included a square-recess bearing,a circular recess bearing,a triangular-recess bearing,and an angled-orifice bearing.Comparisons of the results were made between bearings,the angled-orifice bearing has the most favorable overall performance and has good applications in high speed spindle.
