Abstract

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 gears. The results show that the misalignment error on the plane of action has an enormous influence on mesh characteristics and that it not only changes the contact line and load distribution but also results in a reduced TVMS. Meanwhile, the centre distance error causes the amplitude fluctuation of TVMS and transmission error (TE). The misalignment error on the off plane of action has almost no effect on TVMS and TE. The results can be used for vibration prediction and misalignment fault diagnosis.
