A REVIEW ON DESIGN, ANLYSIS AND MATERIAL OPTIMIZATION OF HIGH SPEED HELICAL GEAR BY CHANGING DEFFERENT DESIGN PERAMETERS USING FEA APPROACH

Gears are one of the most critical components in mechanical power transmission systems. The bending and surface strength of the gear tooth are consider to be one of the main contributors for the failure of the gear in gear set. The three dimensional soli d model can be generated in pro E. This model is imported in ansys and then contact stress and bending stress can be calculated in ansys for deferent face width and helix angle. Contact stress and bending stress can also be calculated by hertz, lewis and A GMA equation. Bending stress can be occur in the root of gear and contact stress can be occur between meshing of two gear. Finally these two methods bending and contact stress results both are compared with each other for deferent face width and helix angl e Different material can also be tried for wight and cost optimization. And also to increase corrosion resistance which might be cause of failure
