FINITE ELEMENT ANALYSIS OF SPUR GEAR USED IN LATHE HEADSTOCK

One of the important parameter of mating gears design is contact stress. This paper deals with the stress analysis of the spur gear used in headstock of a lathe machine. In this paper the stress analysis of mating gears of the spur gear with three different materials is done to determine the cont act stresses generated in the gear theeth. The results obtained from Finite Element Analysis (FEA) using Ansys are compared with the values obtained from theoretical Hertzian equation.The materials of spur gear used for analysis are grey cast iron, high ca rbon steel and medium carbon steel. On comparing the results after theoretical analysis i.e. by using Hertzian equation and through Ansys, very less and acceptable difference between the values of contact stresses found
