Derivation of optimum profile modifications in narrow-faced spur and helical gears using a perturbation method
Résumé
A perturbation method is presented which makes it possible to obtain approximate closed-form expressions for profile relief that minimize the fluctuations of quasi-static transmission errors under load. A number of results are displayed which prove the theoretical effectiveness of the proposed solutions for low and high-contact ratio spur and helical gears. It is also shown that the corresponding relief performance is not significantly downgraded by centre-distance variations. Finally, a number of practical considerations are brought up and commented.
