The power loss is a very important parameter for the planetary gear train. It can significantly influence the transmission performance of the planetary gear train. Thus, the power loss analysis can be helpful for improving the transmission performance of the planetary gear train. To overcome this problem, this paper presents a numerical analysis method to analyze the churning power loss of a planetary gear train. A computational fluid dynamics (CFD) model for a planetary gear train with four planet gears are proposed. The transient oil distribution and pressure distribution in the flow field of the planetary gear train are discussed. It seems that this works can provide some guidance for the improvement method of the churning power loss of the planetary gear train.
