Based on the characteristics of guide bearing of vertical hydropower unit, the derivation process, dimensionless process and discrete process of oil film pressure distribution are introduced in detail. The temperature sticking effect was taken into account when calculating the pressure distribution of oil film. The calculation method of oil film temperature distribution was introduced. The algorithm to calculate the oil film pressure distribution under the temperature distribution of oil film was given. The oil film pressure distribution calculation software was designed and given The calculated results can provide the data foundation for solving the bearing clearance adjustment of hydropower units and the life prediction of bearing bush.
