This article deals with the static and dynamic interactions between journal bearings and gears in mechanical transmissions. The proposed approach combines classic lumped parameter and shaft elements, a specific wide-faced spur or helical gear model and external bearing forces. Bearing reactions are determined based on the linearized and non-linear solution to the Reynolds equation for short bearings. The corresponding parametrically excited non-linear state equations are solved by inserting a Newton-Raphson’s method and a unilateral normal contact algorithm into a Newmark’s time-step integration schema. Finally, the influence of bearing non-linearity, external and internal forcing terms is analyzed on several single stage reduction units with spur and helical gears.
