Stress analysis of composite spur gear using ansys workbench

Abstract

A spur Gear is in working condition subjected to stresses, which causes failure of teeth. Due to this performance of gear affected and power transmitting capacity decreases. To overcome this problem, it is essential to find out any other material which will improve the performance of spur gears. In this present paper, stress analysis have done with replacing aluminum alloy gear with new composite material using Ansys workbench. For this the marine application has taken for design and model of spur gear is carried out in Solid works 2016. When a pair of spur gear tooth is considered, it is generally subjected to two cases of cyclic stress: contact stress and bending stress. It is not possible to reach both stress to their maximum values at the same point of contact fatigue. So, in many applications such as aerospace, automotive, marine to minimize this type of failure, analysis is carried out in the design stage and on the basis of results modifying tooth surfaces or production method. From this analysis, it is concluded that stress values for the new composite material have indicated lesser than aluminum alloy. So, it is better to use this composite material spur gear for the marine applications.
