A Model for Analysis of Time-Varying Mesh Stiffness of Helical Gears with Misalignment Errors [PDF]
Transactions of FAMENA, 2021 A mathematical model is proposed to calculate the time-varying mesh stiffness (TVMS) of helical gears under the condition of gear misalignment by combining the slice method. The proposed method aims to reveal the influences of different misalignment errors (centre distance error, action plane error and off action plane error) on the TVMS of helical ...
