Vibration Characteristics Analysis of a Pair of Aviation Herringbone Gears

摘要

The lumped mass model of an aviation herringbone gear is established, which takes coupling relationship between the two helical gear into consideration. Based on this model, motional differential equation is derived, and excitation parameters of gear pair are calculated at the same time. The dynamic differential equations are solved to obtain the dynamic response of each degree of freedom, then vibration characteristics of aviation herringbone gear in different speed and power is analyzed and the appropriate rotational speed and power of different flight status is determined. Research on the reliability analysis of aviation herringbone gear and the dynamic efficiency analysis is of great significance.
