In a mechanical power transmission system and all rotating machinery, gear is one of the most complicatedcomponents in mechanical power transmission system. Gear teeth in action are subjected bending stresses with fatigueand contact stresses causing contact fatigue. The bending and surface stresses of the gear tooth are considered to be oneof the main contributors of the failure of the gear in a gear set. Thus analysis of stresses is more important in a area ofresearch on gear to minimize or to reduce the failure and for optimal design of gear. This paper presents the stressanalysis of mating teeth of spur gear to find maximum contact stress in the gear teeth. The results obtained from finiteelement analysis are compared with theoretical Hertzian equation value for analysis EN8 material is chosen. The helicalgear are sketched, modeled and assemble in ANSYS 15 design modular. The results show that the difference betweenmaximum contact stresses obtained from hertz’s equation and finite element analysis is very less and it is acceptable.
