Vibratory Response in Helical Gear System (3rd Report, Dynamic Tooth Load and its Control)

摘要

Dynamic tooth load is a pair of forces, which operates at the meshing points of a pair of helical gears. It occurs as a primary reaction of the vibratory system to mesh exciting force. In this paper, two methods of calculating dynamic tooth load are proposed, one is based upon motion of equation reported in the previous report and the other is compliance method based upon a physical exciting model. Applying building block approach to this model, dynamic tooth load is described as an explicit equation. By studying this equation, mechanism in which dynamic tooth load occurs can be classified into six cases. And according to this classification, it is discussed how dynamic tooth load can be controlled. Finally, calculations are done for a simple gear-shaft model, and the proposed strategy in controlling dynamic tooth load is shown to be valid.
