Design & Analysis Of Assembled Teeth Spur Gear

Gears are the most important components in modern mechanical engineering world. The use of gears has more common in all the industries. The advantages of spur gear are simplicity in design and can be manufactured easily, economically and less maintenance. At present scenario gears plays an important role in wide space of research especially in gear motors, gear pumps, electromechanical actuators and drive shafts for the car etc. Gears predominantly fail in contact fatigue mode (pitting/spalling) due to combined rolling and sliding motion. Pitting initiation has been experimentally investigated by many researchers under different loading and operating conditions. Contact and Bending stresses at pitch point happened due to a close agreement. The highest probability of pitting /bending failure initiation is observed in single tooth contact region due to full load sharing and the chance of contact fatigue failure is more in comparison to bending fatigue failure. But if the failure happened in teeth - entire gear is replacing. So, it is so expensive. Our Aim is to design and study the failures of assembled teeth spur gear. In this work, we are going to do conceptual design to detail design with CAD Model and proceed to check the failures using Analysis Tool. Aim to find out the contact stresses and deflection by using Solid works and Ansys software's.
