The loaded transmission error is calculated using Hertzian formulas for the approach deformation of a pair of teeth and approximate formulas based on the FEM analysis for the bending deflection. Analysis of the loaded transmission error proved that the actual contact ratio is an effective index of the loaded transmission error of a helical gear pair. The actual contact ratio is the ratio of the rotational angle to the angular pitch during the period in which a tooth pair is actually in contact. The analysis based on the actual contact ratio clarified the following. (1) The actual contact ratio varies between 1.0 and the geometrical contact ratio, depending on the applied load. (2) The loaded transmission error exhibits maxima when the actual contact ratios are integers. (3) The no-load transmission error whose actual contact ratio is 1.0 results in the absolute maximum. (4) A gear pair with low level of no-load transmission error exhibits low level of loaded one.
