Influence of Pitch Error on Vibration, Bifurcation, and Chaos Characteristics of the Helical Gear Pair System

Table 3

Variations of vibration acceleration amplitude in each degree of freedom direction of the helical gear pair system after adding pitch error.

	Tangential direction		Axial direction		Torsional direction
	Driving gear	Driven gear	Driving gear	Driven gear
Variation of vibration acceleration amplitude	0.0009	0.0007	0.0022	0.0019	0.0113
