DESIGN AND STRESS STRAIN ANALYSIS OF COMPOSITE SPUR GEAR IN AUTOMOBILE

To Design and draw a spur gear and Analyse the stress distribution of the cast steel and the composite material. Spur gear is one of the most commonly used component in power transmission between two parallel shafts, they are widely used in mechanical power transmission. Engineering components made of composite materials have find increasing applications ranging from space craft to small instruments. Overwhelming advantages such as higher dimensional stability, light weight, and minimal attack by environment when compared with other ordinary cast st eel gears. Modern level advanced carbon composite materials have opened a new level of soundless, high resilience, lubricant free and precision gearing in power and motion transmission. A proper understanding and prediction of gear failure is an important pre - requisite for any reliable application. In this project, a spur gear is designed using advanced modelling software (Solidworks) and is meshed and analyzed using analysis software by the application of torque load. Finally, by comparing the analysis re sult of both composite spur gear and the existing cast steel spur gear.
