INVESTIGATION TO DETERMINE THE EFFECT OF PHASING ON THE NOISE GENERATED BY SPUR GEARS

Abstract

A test program was performed to evaluate the effect of relative gear tooth contact phasing on the acoustical characteristics of a model transmission. It was concluded that within the limitations of the test configuration, the radiated noise frequency characteristics for a constant tooth contact frequency are a function of the number of gear sets, while the amplitude and directional characteristics are a function of their relative phasing. It was also noted that changes in the torsional elastic properties of the system produced significant changes in radiated noise.
