Abstract :
An 8-DOF(degrees-of-freedom) nonlinear dynamic model of a spiral bevel gear pair which involves time- varying mess stiffness, transmission error, backlash and asymmetric mesh stiffness is established. The effect of the asymmetric mesh stiffness on vibration of spiral bevel gear transmission system is studied deliberately with numerical method. The results show that the mesh stiffness for drive side has more effect on dynamic response than those of the coast side. Only double-sided impact region is affected considerably by mesh stiffness of coast side while single-sided impact and no impact regions are unchanged. In addition, the increase in the mesh stiffness of drive side tends to worsen the vibration stability of the transmission system especially for light load case.
