Dynamic Behavior of Straight Bevel Gears of Gleason Type

Abstract

Dynamic behavior of straight bevel gears of Gleason type was investigated by measuring the dynamic load, circumferential, radial and axial vibration accelerations of gears and noise under different running conditions. It was found that the root stress ratios of maximum dynamic root stress to static one in the toe, middle and heel of a straight bevel gear tooth are almost equal and that the circumferential, radial and axial vibration accelerations of gears are coupled to each other. The circumferential vibration acceleration is considered to be the first source of the vibration and noise.
