Taking three-shaft parallel coupling rotor system with two pairs of helical gears as the research object
a meshing dynamic model with total degrees of freedom was established by considering the effects of the static transmission error and the geometric eccentricity of the gears.Combined with the rotor system
a finite element model of the multi-shaft helical gear rotor system was determined.In the model
the rotor system was simulated by using beam element and the gear pair was simulated by using mesh stiffness matrix and damping matrix.Finally
considering the static transmission error
rotor unbalance
gear geometric eccentricity and the coupling
dynamic characteristics of the system were analyzed.The results show that geometric eccentricity has a great effect on gear meshing force
of which the role is equivalent to a torque applied on the gear.
