摘要

A method based on the minimization of LTE amplitude, axis force and vibration were proposed to reduce the vibration of double helical gears. The modified tooth surfaces were represented by the sum of two vector functions, describing respectively the theoretical tooth surface and the deviation surface. A 10-DOF vibration model was established considering the excitations of time-varying meshing stiffness, corner meshing impact and axial motion based on TCA and LTCA. An improved algorithm was applied to optimize the parameters of modified pinion for getting the best performance. The results show that the loads will tend to be uniform when taking the measures of gear modification and axial motion. Besides, torsional vibration mainly results from corner meshing impact and meshing stiffness excitation which have little effect on axial vibration. The axial motions excitation contribute to both axial and swing vibrations. In brief, the vibration decreases greatly because of smaller excitations by modified double helical gears.
