modelGear

Obsolete model. Use Modelica.Mechanics.Rotational.Components.Gearbox instead

Extends from ObsoleteModelica3.Mechanics.Rotational.Interfaces.TwoFlangesAndBearingH (Obsolete model. Use one of Modelica.Mechanics.Rotational.Interfaces.PartialXXX instead).

Information

This 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.
