| 摘 要： | 为了解决大重型数控转台的单油腔静压推力轴承无法承受偏载荷问题,提出了单油腔静压支承与静压径向轴承复合设计方案。同时,为了方便静压径向轴承油腔加工,提出了一种新式回型槽油腔结构。此种结构的油腔加工区域仅占单油腔总面积的10%,而承载区域达到75%以上。然后,综合应用三维造型软件Pro/ENGINEER和CFD软件FLUENT,模拟分析圆环形静压支承和回型槽油腔的流速分布及压力分布,揭示了两种油腔结构内部油液流动规律,并计算各自的静态性能,实验验证表明,该设计方案正确性与合理性。 |

| Abstract: | In order to overcome the problems that the single oil chamber hydrostatic thrust bearing of a large heavy duty NC rotary table cannot bear partial load,a composite design scheme,which is composed of single oil chamber hydrostatic bearing and radical static pressure bearing,is proposed.Also,to facilitate the processing of oil chamber of radical static pressure bearings,a new type of ring groove oil cavity structure is designed.The oil chamber processing area accounts for only 10% of single oil chamber area,w... |
