| 摘 要： | 本文提出一种外径密封的螺旋槽推力轴承新结构,并利用螺旋槽近似理论对该轴承进行了分析计算。文中给出了承载能力和刚度公式,同时通过实例论证了该轴承具有远大于普通螺旋槽推力轴承的承载能力和刚度。该种轴承结构为进一步提高空气动压推力轴承的工作性能开辟了新途径。

| Abstract: | This paper deals with a newly designed spiral-groove thrust bearing, with a slit seal around it. By the approximate theory of spiral-groove bearing, this new type bearing is analysed. As a result the formulas for calculating load capacity and stiffness of this bearing are given. In order to prove that the load capacity and stiffness of this bearing is much larger than that of conventional spiral-groove thrust bearing, an example is offered. This type of spiral-groove thrust bearing presents a new possibility to improve the performances of gas lubricated thrust bearings. |
