Abstract
This study employs the finite element method to analyze the dynamic behavior of a helical geared rotor system with oil-film bearing. The system comprises the rotating shaft, helical gear pair, and oil-film bearing. The Timoshenko beam model is used to simulate the rotating shaft, and the rotating shaft's rotational inertia and shear strain effect are considered. In consideration of the gyroscopic effect, the helical gear pair is assumed to be two rigid disks, and a linear spring and damper are connected along the pressure line of the disks for simulation. This study investigates the effects of bearing lubricant viscosity, bearing radial clearance, bearing diameter, bearing length, bearing length-to-diameter ratio, helix angle, and an inner diameter of the rotating shaft on the systems' axial and lateral dynamic response for determining the system's dynamic properties. The simulation results serve as a reference for academic researchers and industrial practitioners wishing to further investigate helical gear rotor systems with oil-film bearings.
