Previously known calculation methods permit the compen-sation of nominal ~ actual deviations on flank surfaces of spi-ral bevel and hypoid gear sets on the basis of correction matrixes.’ These are expanded forms of well known pro-portional changes, e.g., manual ABC corrections.The newly developed method described in this paper func-tions on the basis of data obtained through a one-time theo-retical flank generation using a bevel gear simulation pro-gram. Due to its universal validity, this vectorial computa-tion method is applicable in all presently known spiral bevel and hypoid gear manufacturing processes. Yet the method is based on a highly visual and transparent model which may be described as three spatial triangular vectors in a Cartesian coordinate system.
