COMPUTER AIDED DESIGN AND NUMERICAL ANALYSIS OF INVOLUTE SPUR GEAR – A NOVEL STUDY BY FEA
Keywords:
Involute Gear, MAT Lab , Numerical AnalysisAbstract
Gears are widely used in transmission system which undergoes cyclic loads in service. Maximum load transmitted by the gear has been an important factor in designing of a gear.The maximum stress induced on the gear tooth when it meshes with other gear should be less than its capability so that its life will be lasting. It is necessary to understand the deformations and stresses induced in the components are within the desirable limit. So it is necessary to analyze the load acting on the tooth while transmission and the corresponding induced stress on the gear tooth. Based on the above said analysis the induced stress is predicted on the tooth. The force and stress analysis is made to justify the result by analytically and using FEA tools. A spur gear profile was created MATLAB programming. A CAD model was created using SolidWorks software. FEA analysis was performed using ANSYS.The present study elucidates the mechanical and bending behavior of spur gear tooth. It can serve as valuable basis to enhance more accurate models, and obtaining all numerical parameters needed for elaboration of the system.
