The Nonlinear Vibration Characteristics of Gear Swing System of Overload Swing Angle Milling Head

摘要

The overloaded swing angle milling head is an important part of the CNC machine tools; the swing system is the drive components of overloaded swing angle milling head for feed movement, mainly by gears for cutting the feed motion. In this paper, a multi-degree-of-freedom nonlinear dynamic model with multi-level multi-backlash spur gears was established, by using of numerical analysis method to solve the analysis of gears wing nonlinear vibration characteristics of the system, the results show that the gaps between the gears have a rich nonlinear characteristics of the vibration of the system.
