Description

Transmission efficiencies of high reduction face gear drives were investigated. The obtained results are as follows. (1) The equation to calculate theoretical efficiencies of general face gear drives was derived and the calculation examples were shown. (2) In face gear drives, there is an optimum offset between pinion and gear axes to maximize the efficiency. (3) The face gear drives with gear ratios were made and the efficiencies were measured. As the results, the high efficiencies of 88〜95 % were obtained. In this case, the estimated friction coefficients were in the range of 0.05〜0.07.
