摘要/Abstract

摘要： 为改善阻尼环对航空发动机传动齿轮的减振效果，提出了阻尼环在自由状态下的型线设计方法，设计了一种均压环。开展了对阻尼环的接触分析，对比计算了普通阻尼环与均压环在齿轮振动时的摩擦耗能，探究了阻尼环局部非接触对摩擦耗能的影响。结果表明，在静止安装状态下，普通阻尼环与安装槽的接触圆心角为114°56′，工作过程中，随着转速提升，接触区域将会增大，但均压环与安装槽的接触区域始终比普通阻尼环更大，且不受转速影响，从而在齿轮发生共振时能消耗更多的振动能量，有效提高阻尼环减振效能。

Abstract: In order to improve the effects of ring damper on the vibration reduction of aeroengine transmission gears， the shape design method of the ring damper in free state was proposed， and a grading ring was designed. The contact analysis of the ring damper was carried out， and the frictional energy dissipation of common ring damper and grading ring in gear vibration was calculated. Moreover， the effect of local non-contact of ring damper on frictional energy dissipation was analyzed. The results show that the contact center angle between the common ring damper and the mounting groove is 114°56′ under the static installation. During the working process， the contact area will increase with the rotating speed increasing， but the contact area between the grading ring and the mounting groove is always larger than the common ring damper， and is not affected by the rotating speed， so that more vibration energy can be dissipated when the gear resonates， and the ring damper vibration reduction can be effectively improved.
