Reference Point, Mesh Stiffness and Dynamic Behavior of Solid, Semi-Solid and Thin-Rimmed Spur Gears


Many models for predicting the dynamic behavior of gears do not take into account the blank flexibility and modes of vibration. The paper presents results for solid, semi-solid and thin rimmed spur gears. The analysis is made for the natural frequencies, when finite element models of meshing spur gears are referenced. Results show that a reference point inside the gear blank yields excellent correlation between the natural frequencies extracted from the RD-FT and F.E.A. models.
