modelGearConstantEfficiency
Extends from Modelica.Mechanics.Rotational.Icons.Gear (Icon of a rotational gear), Modelica.Mechanics.Rotational.Interfaces.PartialElementaryTwoFlangesAndSupport2 (Partial model for a component with two rotational 1-dim. shaft flanges and a support used for textual modeling, i.e., for elementary models), Modelica.Thermal.HeatTransfer.Interfaces.PartialElementaryConditionalHeatPortWithoutT (Partial model to include a conditional HeatPort in order to dissipate losses, used for textual modeling, i.e., for elementary models).
Information
This element characterizes any type of gear box which is fixed in the ground and which has one driving shaft and one driven shaft. The gear has constant efficiency but it does not have inertia, elasticity, damping or backlash. If these effects have to be considered, the gear has to be connected to other elements in an appropriate way.
Parameters

| Real | ratio | Transmission ratio (flange_a.phi/flange_b.phi) | |
| Real | efficiency | 1 | Constant efficiency coefficient |
| Boolean | useHeatPort (from PartialElementaryConditionalHeatPortWithoutT) | false | = true, if heatPort is enabled |
