Stress Analysis of Bevel Gear Tooth using FEA: A Review

Gears are the device used to transmit motion from one shaft to another shaft by direct contact. Tooth of the gear is most important device in a gear system and has focused in the current study. A detailed study about the earlier work conducted on the design and stress analysis of tooth of bevel gear using ANSYS and other simulating software is presented. Discussion about the types of materials being used for manufacturing of tooth of bevel-gear and the stress acting on the surface of tooth of bevel gear and its parts has presented. Tool geometry has represented for the nomenclature used during its bevel-gear design and manufacturing. Literature shows that helical bevel gear is best and can be manufactured on the same unit that of spur gears with same precision. Tooth of the gear is the most important part as they goes under high load and stress which are the reasons of the failure of gear. A design of the bevel gear is presented in the paper. 20 number of tooth has considered at the profile of the gear.
