Design, Analysis & Fabrication of the Powertrain System for All-Terrain Vehicle

The primary goal of this project is to design, analyze, and build a two-stage reduction gearbox for use in all-terrain vehicles. A gearbox is a mechanical device that consists of a number of gears housed in a casing or a basic gear train. It transmits speed and torque conversions from the engine or CVT to the wheels, making it the most important component of the powertrain system. The gears inside the gearbox can be any of the many various types of gears available on the market, ranging from spur gears to worm gears and even planetary gears. The gearbox used in this article is a spur gear train. This paper focuses on selecting the gearbox's overall reduction ratio, as well as material selection, gear dimension selection, shaft dimension selection, key design selection, and bearing selection from the SKF bearing catalogue The bending and wear strengths are estimated to determine the factor of safety, and then the results are validated using Finite element analysis.
