This paper derives new equations for calculating the efficiencies of differential gear drives using simple laws based on mechanics, When the new equations are used, the efficiency for speed reduction is lower than that for speed increase, in most cases. This is completely opposite to the case of the results obtained from the earlier equations. The reason for this is clearly shown by analyzing the power flows used for deriving the equations. It is found that the power flows used for deriving the earlier equations do not satisfy the boundary conditions due to an assumption which is unconsciously introduced in the process of deriving the equations. Numerical calculations are conducted and differences in the efficiencies are shown in the case of representative differential gear drives.
