Modeling, Analysis and 3D Printing of Gearbox

Abstract - A gearbox is a mechanical device that transmits power and adjusts the speed and torque of an engine or motor. It consists of a series of gears that can change the output speed and direction of rotation. Gearboxes are essential in various applications, from automobiles to industrial machinery, ensuring efficient performance. They come in various types, including manual, automatic, and planetary gear systems, each designed for specific operational needs. The main aim of this paper is to focus on the mechanical design on assembly of gears in gear box when they transmit power at different speeds. The metals selected for the gears is Aluminium Alloy by utilized materials for riggings and apparatus shafts is cast steel. In this paper to supplant the materials with Aluminium material for diminishing weight of the item. Stress, uprooting is investigated by considering weight diminishment in the rigging box at higher speed. Gear box assembly model is created by using Solid works software and a prototype of gear box is created by using 3D printing technology to check with design changes. Key Words: Gearbox, Gear assembly, Powe transmission, Aluminium alloy, cast steel, stress analysis, Displacement analysis, Weight reduction, 3D printing, Mechanical design, High-speed operation.
