Sažetak
In this investigation into the technology of tooth profile modification, we analysed the impact of meshing, meshing shocks, and load distribution of high contact ratio gears in detail and explained the necessity of tooth profile modification so that a reduction in vibration and noise of high contact ratio gears can be achieved. Firstly, a design of a conventional profile modification curve is introduced, secondly, a new profile modification curve is derived from the transmission error calculated by using the slicing method, and thirdly, the time-varying meshing stiffness of gears with conventional and new profiles is calculated based on the finite element method. Finally, a comparative analysis of the time-varying meshing stiffness of gears shows that there exist a general effect of profile modification curves on the time-varying meshing stiffness of high contact ratio gears and an outstanding effect of the new profile modification curves on vibration and noise reduction. The paper also presents a new method for designing high contact ratio profile modification based on transmission error.
