Helical gears with bias modification are used to suppress the vibration of gear transmissions. However the dynamics of a gear pair with bias modification is not clear. In this paper, bias modification are defined on plane of action, and the performance of gears with bias-out modification and the performance of gears with bias-in modification are presented based on the study of dynamic behavior of a helical gear system with gear surface modification. And the performance of gears with bias modification when shaft is with misalignment are also discussed.
