.ObsoleteModelica3.Mechanics.Rotational.Gear .ObsoleteModelica3.Mechanics.Rotational.GearThis component models the essential effects of a gearbox, in particular gear efficiency due to friction between the teeth, bearing friction, gear elasticity and damping, backlash. The inertia of the gear wheels is not modeled. If necessary, inertia has to be taken into account by connecting components of model Inertia to the left and/or the right flange.
