In this paper, the conformal transformation between curved surfaces is used to transform the spherical lubrication problem into a planar lubrication problem. The approximate analytical expression of the bearing capacity of the equilateral spiral groove ball bearing and the stiffness of the gas film are derived and the optimal groove parameters are derived. The result of this paper is suitable for small compression and small eccentricity.
