Paper 14: Dynamics and Noise of Parallel-Axis Gearing

Abstract

This paper gives a general account of gear dynamic tooth loads and noise. Experimental work in progress is used to illustrate the steps in a dynamic analysis of a gear system. The nature and specification of the excitation sources at the tooth contact, and the generation of tooth contact frequency components and of their sidebands for spur and helical gearing are described, together with the vibrational and acoustic responses and the correlation between excitation and response. The analysis indicates how control of dynamic load and noise can be achieved.
