Design, Modeling and Structural Analysis of Helical Gear for ceramic and steel material by using ANSYS

Abstract

This project mainly deals with the design and analysis of helical gear with involutes profile. The involutes gear profile is the most commonly used system for gearing today. In an involutes gear, the profiles of the teeth are involutes of a circle. In involutes gear design contact between a pair of gear teeth occurs at a single instantaneous point. Rotation of the gears causesthe location of this contact point to move across the respective tooth surfaces. The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement.This gradual engagement makes helical gears operate much more smoothly and quietly than spur gears. For this reason, helical gears are used in almost all power transmissions. One interesting thing about helical gears is that if the angles of the gear teeth are correct, they can be mounted on perpendicular shafts, adjusting the rotation angle by 90 degrees. Under this project the Helical gear with involutesprofile is designed with the help of CATIA V5R16 software modal and static
