ANALYSIS OF CRACK DEFECT IN SPUR GEAR ON STRENGTH USING FINITE ELEMENT ANALYSIS

Gears are the power transmission elements. Gears are used to transmit motion as well as power from one member to another. Any defect in gear will result in variation of power and torque. Gear teeth fails due to the static and the dynamic forces and the contact between the two meting gears causes the surface failures. To get the gear of more durability use of improved material, hardening of surface of gear, heat treatment and carburization, shot peening etc are performed over the gear. Present work deals with the analysis of effects of spur gear crack defect on strength with variation of gear parameters using Finite Element Analysis. Module, No of Teeth, and Pressure Angle considered for the analysis. For modeling and analysis CAD/CAM software Pro-Engineer Wildfire is used.
