摘 要： In this paper, we numerically analyzed the static and dynamic performances of herringbone thrust hearing, step pocket thrust bearing, taper pocket thrust hearing and taper flat thrust bearing. The optimal values of design parameters of each type of thrust hearing in terms of both maximum axial stiffness (k{sub}zz) and maximum axial stiffness to friction torque (T) ratio (k{sub}zz/T) and bearing performances in both cases are calculated. We compared their optimal performances in terms of application conditions for a hard disk spindle. It is found that step pocket thrust bearing and taper- pocket thrust bearing are obviously superior to herringbone thrust bearing and taper-flat thrust bearing with respect to both maximum k{sub}zz and maximum k{sub}zz/T. We also found that the dams of thrust bearings with pockets play a great role in improving the bearing performances. It was made clear that taper pocket thrust bearing and taper-flat thrust bearing have much larger maximum load capacity than pocket thrust bearing and herringbone thrust bearing.

本文对鱼骨式推力轴承、台阶式凹槽推力轴承、锥形凹槽推力轴承和锥形平底推力轴承的静态与动态性能进行了数值分析。针对每种推力轴承，计算了在最大轴向刚度（kzz）和最大轴向刚度与摩擦扭矩（T）比值（kzz/T）两个指标下的设计参数最优值，并分别评估了其承载性能。我们比较了它们在硬盘主轴应用条件下的最优性能。结果表明，在最大kzz和最大kzz/T方面，台阶式凹槽推力轴承和锥形凹槽推力轴承明显优于鱼骨式推力轴承和锥形平底推力轴承。同时发现，带有凹槽的推力轴承结构对提升轴承性能具有重要作用。研究还明确指出，锥形凹槽推力轴承和锥形平底推力轴承的最大承载能力远高于带凹槽推力轴承和鱼骨式推力轴承。
