Abstract: A global model of mechanical transmissions is introduced which deals with most of the possible interactions between gears, shafts, and hydrodynamic journal bearings. A specific element for widefaced gears with nonlinear ...

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: A three-dimensional (3D) dynamic gear model is presented which combines classic shaft, lumped parameter, and specific two-node gear elements. The mesh excitation model is based on transmission errors (TEs), and its ...

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 ...

Abstract: An original hybrid gear model is introduced, which combines lumped parameter and finite elements along with a specific interface aimed at coupling mismatched discrete models. A mortar-based interface is presented, which ...
