Theoretical and analytical research on load sharing in helical gear with evaluating the FEA method and computerized approach of AGMA standards

Gear teeth are subject to two different types of stresses: root bending stress and tooth contact stress. Gear teeth break under these two stresses.: contact stress cause pitting failure at the contact surface, and root bending stress causes fatigue fracture. Thus, while constructing gears, both of t...

Summary:Gear teeth are subject to two different types of stresses: root bending stress and tooth contact stress. Gear teeth break under these two stresses.: contact stress cause pitting failure at the contact surface, and root bending stress causes fatigue fracture. Thus, while constructing gears, both of these strains must be taken into account. Typically, strongly loaded gears are built of ferrous materials, which can withstand bending loads indefinitely. However, it is impossible to create gears that are impervious to surface failure. In industries where power transmission under big loads with smoother and quieter operation is required, helical gears are frequently utilized. Solidworks, a robust and contemporary solid modelling software, creates three-dimensional solid models with differing face widths to determine stress distribution, and ANSYS, an application for finite element analysis, does the numerical solution. The Lewis stress formula is the foundation of the analytical research. A helical gear was modelled on CAD Software for this paper's stress study, which was completed on ANSYS. The outcomes are then contrasted with AGMA Standard.
