EFFECT OF PITTING ON MESHING STIFFNESS OF GEARS
Jixie qiangdu, 2020 The change of meshing stiffness of gears is caused by the change of meshing position and meshing number between gears when the gears are running.The change of meshing stiffness reflects the change of meshing process of gears.When pitting occurs,the meshing stiffness of gears will change,which will lead to the change of vibration law of gearbox.This ...
