ANALYSIS OF SPALLING DEFECTS IN SPUR GEAR ON STRENGTH USING FINITE ELEMENT ANALYSIS

Abstract

Two meshing gears are transmitting rotational motion as well as power. Any defect in gear will effect in variation of power and torque. Gear teeth fails due to forces and the contact between the two meting gears. Spalling is similar to destructive pitting except that the pits are usually larger in diameter and quite shallow. Present work deals with the analysis of effects of spur gear spalling defects on strength with variation of gear parameters using Finite Element Analysis. Modules, No of Teeth, Pressure Angle are considered for the analysis. For modeling and analysis CAD/CAM software Pro-Engineer Wildfire is used.
