Design and Analysis of Novel Non-Involute Cylindrical Gears with a Curved Path of Contact

In this paper, novel non-involute cylindrical gears are designed based on a curved path of contact. Firstly, parabolic curve is predesigned as the contact gears. Then, tooth profiles calculated using differential geometry and spatial meshing theory. Secondly, three-dimensional models established according to machining simulation. Thirdly, simulation model (including misalignment error longitudinal modification) analyze performance Finally, an example given, results show that presented have greater load-carrying capacity compared with involute Moreover, whether modified or not, without error, stresses lower than those
