Vibration reduction connecting structure of propeller hub fairing

The invention relates to connecting structures of fairings, in particular to a vibration reduction connecting structure of a propeller hub fairing. The vibration reduction connecting structure comprises a propeller hub fairing front support and a propeller hub fairing rear support which are connected through bolts. Rubber linings are arranged in the support and bolt connected structure positions.The technical problems such as vibration and noise, caused by an unbalanced propeller hub mounting structure, of a turboprop are solved, the fatigue performance of a turboprop mounting structure can be effectively improved, and the service life is prolonged. 本发明涉及种整流罩连接结构，特别涉及种桨毂整流罩减振连接结构。所述的结构包括桨毂整流罩前支架和后支架，前支架和后支架通过螺栓连接，支架和螺栓连接结构处设置有橡胶衬套。本发明解决了涡桨类发动机由于桨毂安装结构不平衡带来的振动和噪音等技术难题，可以有效地改善发动机安装结构疲劳性能，延长使用寿命。
