Numerical and experimental research of helical gear contact stress considering the influence of friction

open access: yesFrontiers in Mechanical Engineering, 2022
Helical gears are widely used in various mechanical transmissions. Thus, analysing gear contact stresses is crucial to improve the fatigue limit and life of gears. In this paper, the contact stress of helical gear is analyzed by finite element simulation
