Abstract

Planetary gear trains are generally used in helicopters, aircraft engines, automobiles, and wind turbines for speed reduction and slowdown motors and increase the torque. The general problems in a common gearbox are gear failure problems due to the wear and tear of the gears during rotating and the vibrations produced while transmission. This problem occurs in most gearboxes but in the case of the planetary gearbox, these problems cant be found before failure due to the complex shape of the planetary gearbox. The main objective of this project is to develop a parametric model of the planetary gearbox by using Catia v5 and perform the Static modal analysis in ansys software by using the various materials like Structural steel, AL 7075, 15Ni5Cr4Mo1, Grey cast Iron using different revolutions (2500rpm, 3500rpm) under static and modal loading conditions. Comparisons of Stress, strains, deformations using Ansys .Finally were concluded on the best material based on the results
