【摘要】 本文用有限元法对新型动压轴承──螺旋三油楔动压轴承的静、动特性进行了分析计算和初步应用试验。研究结果表明：把油楔加工成螺旋形，不仅有利于将润滑油导入整个润滑表面，而且能显著改善轴承的温升和动力特性。更多还原

【Abstract】 The static and dynamic characteristics of a new hydrodynamic bearing with three spiral oil wedges are analyzed and calculated with finite-element method and a primary experiment is carried out. The research makes clear that the spiral oil wedges are not only favourable to lead lubricating oil into the whole bearing surface, but also to lower the temperature and to improve the dynamic performance of the bearing更多还原
