Fabrication method of straight bevel gear shaping processing template

The invention provides a fabrication method of a straight bevel gear shaping processing template, and relates to improvement of a fabrication method of a straight bevel gear shaping processing template. The supporting template obtained by the fabrication method can meet different gear parameter requirements and has small gear shaping errors. The fabrication method comprises the following steps: calculating a horizontal coordinate and a longitudinal coordinate of a curve of a template for double-tool gear tooth surface machining according to formulas as follows: Xi=xi+etaixR and Yi=yi+etaiyR, or calculating a horizontal coordinate and a longitudinal coordinate of a curve of a template for single-tool upper-lower gear tooth surface machining according to formulas as follows: Xi=xi+etaixR, Yi=yi+etaiyR, Xi*=Xi-etaixR and Yi*=-yi+etaiyR; and making cross sections of the curve of the template to process a curve according to coordinate points Xi and Yi or coordinate points Xi, Yi, Xi* and Yi*.
