The gearbox is modeled using Solidworks and then analyzed based on finite element analysis method using Ansys workbench. In this paper the gearbox is designed, considering the requirements of a mining conveyer belt. Helical gears are chosen for gearbox design as they are extensively used in industrial operations for power transmission under heavy loads with smoother and noiseless operation. The motive to develop a new gearbox is to improve in terms of safety, durability, and efficiency.

3-Stage gearbox is chosen as it can work under high gear ratio very efficiently and effectively for speed reduction. This paper focuses on designing an optimized 3-stage gearbox. Reduction Gearbox are widely used in many industrial applications like Conveyer belts in underground mines, Extruders, Cranes, Crushing Machine, etc.
