FINITE ELEMENT ANALYSIS OF CONTACT STRESS-STRAIN IN MESHED SPUR GEAR

Abstract

A gear is a rotating machine part having cut teeth which mesh with another toothed part to transmit rotary motion and power from one shaft to another. Structural analysis has been a key area of research to minimize failure and optimize design. This research presents the structural analysis of contact area in meshed spur gear assembly using finite element analysis (FEA) method. The spur gears were modeled and assembled using Pro/E software and then imported in to ANSYS workbench for the analysis of stress-strain structure. The result showed that CAE tool was an excellent approach for analyzing defect. Also with optimum utilization of integrated CAD/CAE system, the manufacturing  industries can greatly improve on their process capabilities, predict possible defects before the manufacturing tryout, identify the causes of defects and achieve high quality components at low cost, in a shorter time and greatly enhance the competitiveness of the industry.
