Static and dynamic stress analysis of Spur gear considering effects of Geometric and dynamic parameters

Abstract

Gear design is considered to be one of the most important and newlinecomplicated fields of mechanical engineering design because of its wide newlineusage and applications in mechanical and electrical systems newlineDue to the high working speed requirements in industry of rotating newlineComponents gear design development becomes quite noticeable and rapid in newlinethe vicinity of parameters and effects of dynamic load and dynamic stresses newlineon its performance Consequently this work concentrates on the variation of static newlinegeometric parameters on gear tooth design as also the dynamic loading In newlinethis present work the spur gear of straight tooth is chosen under the theory of newlineinvolute gears The theories and formulations of spur gear tooth profile are newlineinvestigated by its two parts Involute and Trochoid and a geometric method newlinefor involute gearing is introduced This method discriminates the involute newlinegear tooth into segments to determine the conjugate profile instead of newlinefollowing a point to point analytical approach to determine the path of newlinecontact the geometry of the generating rack and mating wheel while the newlineactual tooth thickness is considered with infinitesimal local involutes newline newline
