Abstract: A perturbation method is presented which makes it possible to obtain approximate closedform expressions for profile relief that minimize the fluctuations of quasistatic transmission errors under load. A number of results ...

Abstract: An alternative formulation for the definition of profile modifications in highcontactratio (HCR) spur gears is presented which makes it possible to select optimum relief with regard to transmission error (TE) fluctuations ...

Abstract: Approximate formulae are presented which give the timevarying mesh stiffness function for ideal solid spur and helical gears. The corresponding results compare very well with those obtained by using twodimensional (2D) ...

Abstract: This paper is mostly aimed at analyzing optimum profile modifications (PMs) in planetary gears (PGTs) with regard to dynamic mesh forces. To this end, a dynamic model is presented based on 3D twonode gear elements connected ...
