Abstract: “A method is presented for the optimization of design and manufacture of spiral bevel, hypoid, and worm gears. The aim of the optimization is to improve the operating characteristics of the gear pair, namely, to increase the service life of gears and to reduce the dynamic effects of gear mesh. Optimal modifications are introduced into the tooth surfaces to simultaneously reduce the maximum tooth contact pressure and transmission errors. These modifications are introduced by applying optimal machine tool settings and geometry of cutting tool in the manufacturing process. The method is demonstrated on spiral bevel, hypoid, and worm gears. The obtained results have shown that significant improvements in the operating characteristics of the gear pairs are achieved.”
