Design and Analysis of High Speed Helical Gear with Different Helical Angles

Abstract

Marine engines are among heavy-duty machineries, which need to be taken care of in the best way during prototype development stages. These engines are operated at very high speeds which induce large stresses and deflections in the gears as well as in other rotating components. For the safe functioning of the engine, these stresses and deflections have to be minimized.

            In this project, we created one helical gear with calculations in CAD tool Creo-2/Pro-E which is having helical angle 20 degrees and face width 32mm and pressure angle 20, by using CAE tool ANSYS WORKBENCH we applying high rotational speed and high pressure and high torque values in static structural then we finding deformation of the object and maximum stress values and safety factor values

            The aim of this project is reducing the stress values on the object, to minimizing the stress we following 3 methods

1. 1.      Design constant material change
2. 2.      Design changing material constant
3. 3.      Design and material both changing
