Design and Optimization of tooth Profile Modification of Spur Gear by FEA Approach
Abstract
The most important component in vehicle is Gear, In order to accomplish high load carrying capacity with reduced weight of gear drives but with increased strength in gear transmission, gear tooth stress analysis, tooth modifications and design of gear drives are becoming major research area. The failure of gear teeth occurs for particular reason such as high load carrying capacity, high speed rotation etc. The bending stress is largest in the root fillet radius of the gear teeth. So the modified fillet radius gives reduction of bending stress and contact stress .The goals of the existing study is the to study the effect of tooth stresses and tooth deflection in spur gear drive , to study the effects of these performance parameter in the addendum and centre distance modified spur gears at critical zones of single tooth contact and to develop a technique to design and model spur gears. The performing constraints of standard and spur gear gears were determined through Finite Element Analysis (FEA). Thus the proposed design (circular root fillet) withstands higher bending strength rather than the standard root fillet design.
