Abstract—This work deals with the characteristics of involutes gear system including contact stresses, bending stresses and the transmission error of the gear in mesh the gear system of the unity industry for this work. To estimate the transmission error in the actual gear system which arises because of a irregular tool geometry or imperfect geometry or imperfect mounting the characteristic of the involutes spur gear are analyzed by using finite element method. The contact stresses are examined by using 2D FEM Model. And the bending stresses in the tooth root are examined by using 3D FEM Model. The conventional method of calculating gear contact stress using Hertz’s theory for verification by 2D FEM analyzer using ANSYS, in later investigation the stiffness relationship between two contact area is usually established using a spring place between source and target surfaces for the contact generation between two gears. The stresses are compared with theoretical result. This work also considered static transmission error and analysis of load shearing method using displacement vector and the effect of this error in the actual transmission power of the mesh gear.
