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.

在本文中，我们对人字形推力轴承、阶梯型凹槽推力轴承、锥形凹槽推力轴承和锥形平推力轴承的静态和动态性能进行了数值分析。针对每种推力轴承的设计参数，我们计算了在最大轴向刚度（k{sub}zz）和最大轴向刚度与摩擦扭矩之比（k{sub}zz/T）这两个指标方面以及在两种情况下（即在应用条件方面）的最优值，并评估了其承载性能。我们比较了它们在应用条件方面（针对硬盘主轴）的最优性能。结果表明，阶梯型凹槽推力轴承和锥形凹槽推力轴承在最大 k{sub}zz 和最大 k{sub}zz/T 方面明显优于人字形推力轴承和锥形平推力轴承。我们还发现，带有凹槽的推力轴承的垫圈在提高承载性能方面发挥了重要作用。明确的是，锥形凹槽推力轴承和锥形平推力轴承的最大承载能力比带有凹槽的推力轴承和人字形推力轴承要大得多。
