A gearbox is part of a mechanical system of gears and shafts used to reduce the speed of rotation of the input shaft at a slower rotational speed of the output shaft. This reduction in output velocity helps increase the torque of a system. Reduction gears are widely used in power transmission devices to reduce high rotational speeds. Gears have a wide variety of applications. Gears are the most important component in the power transmission system. Gears generally fail when the tooth effort exceeds the safe limit. It is essential to determine the maximum stress at which a gear tooth is subjected under a specified load. To avoid faults The analysis is performed on the gears. In this study, visualize the forces, the torsion moments, and the bending moments that are created on the shaft during the operation. In the process of power transmission at a given rotational speed, the shaft is inherently subjected to a torque, or torque. Therefore, the torsional shear stress is developed on the shaft. The finite element analysis was performed to obtain the variation of the magnitude of the stress in critical places. The three-dimensional model of the gear shaft was created in the Pro-E software. The load was then applied to the FE model and boundary conditions were applied according to the engine mounting conditions in the ANSYS. . In addition, an axle usually carries power transmission components, such as gears, belt pulleys or chain sprockets, which exert forces on the axle in the transverse direction (perpendicular to its axis). These transverse forces cause bending moments to develop at the axis, which requires an analysis of the stress due to bending. In fact, most axes need to be analyzed for combined stress.
