Numerical Calculation of Planetary Gear Train Involute Modified Gear Time-Varying Meshing Stiffness
摘要
Abstract
The time-varying gear meshing stiffness is the main cause of gear vibration.To caculate the time-varying meshing stiffness has vital significance.Based on geometric parameters calculation method of external gear tooth profile in positive modified planetary gear train,according to the differences between external and internal gear tooth profiles,the geometric parameters calculation method of internal gear tooth profile was deduced in detail.Using Ishikawa tooth deformation calculation formula and stiffness calculation formula,positive modified planetary gear train internal and external time-varying meshing stiffness curves can be got by Matlab programming.Compared with the calculation result of Weber energy method,maximum static stiffness error is 3.7% and the first four order harmonic amplitude maximum error is 9.1% without considering the small amplitude value of the dynamic stiffness.Calculation accuracy meets the requirements.It can provide relatively accurate meshing stiffness for motion differential equation of the planetary gear train.关键词
