Dynamic Behavior of Straight Bevel Gear : 2nd Report, Vibration of Bevel Gears on Rectangular-coordinate

Abstract

Using an inductance type vibrometer for shaft, the displacement of bevel gears is measured on a rectangular-coordinate, and the results are discussed. The results are as follows : The displacements of three directions perpendicularly intersecting each other are influenced by the bending stiffness of gear shaft and the stiffness of bearings. The displacements of three directions are influenced by the natural frequencies for torsional vibration of a gearing system and the natural frequency for bending vibration of a gear shaft. The vibration of high frequencies of 2fz, 3fz, 4fz etc. appears in the axial displacement of bevel gears. The vibration of low frequency is considerable influenced by the stiffness of bearing materials.
