Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This component is used to model a 1-dim. gearbox with non-parallel axes (defined by parameters n_a, n_b). A 3-dim. bearing frame is necessary to reflect the correct support torque, as the axes of rotation of flange_a and flange_b and the direction of the support torque vector are different in general.

Note: The name BevelGear1D is kept only for simplicity. Regardless, this component could be used to model any kind of gearbox with non-parallel axes. For a usage example, see Examples.Rotational3DEffects.BevelGear1D.
