摘　　要：提出了一种新型的气体球轴承结构,其球头尺寸大于球窝尺寸,称为过盈型静压气体球轴承。采用三维有限体积法对此类球轴承的静态特性进行了计算分析,并与传统的间隙型和跑合型静压气体球轴承进行了对比,表明本文提出的过盈型静压气体球轴承在承载力和静态刚度方面均有显著优势。A new type of bearing structure with the ball size exceeding the socket size（can be called as the pressurized spherical gas bearing with interference fit） was developed.The 3-dimensional finite volume method was used to calculate the static characteristic of the new bearing and its results were compared with those of the traditional bearings with snug fit and running fit.The comparison showed that the bearing capacity and the static stiffness of the new bearing with interference fit are much better than those of the traditional ones.
