断开装置及航空发动机
Abstract:
本发明涉及一种断开装置及航空发动机，其中断开装置用于将可失效转子(12)的支承结构断开，该支承结构包括第一支承结构(3)和第二支承结构(4)，第一支承结构(3)设置在靠近可失效转子(12)的一端，第二支承结构(4)设置在远离可失效转子(12)的一端，第一支承结构(3)与第二支承结构(4)通过连接件(1)进行连接，断开装置能够在可失效转子(12)失效时通过使连接件离开连接位置而使第一支承结构和第二支承结构断开连接。本发明的断开装置在转子断裂失效时，能够通过使连接件离开连接位置的形式，使得第一支承结构与第二支承结构断开连接，从而避免转子失效后所带来的不平衡载荷的传递，保证发动机工作的可靠性和安全性。
Abstract(English):

The invention relates to a cut-off apparatus and an aeroengine. The cut-off apparatus is used for cutting off of a supporting structure of a failure-likely rotor (12); the supporting structure comprises a first supporting structure (3) and a second supporting structure (4); the first supporting structure (3) is arranged on one end close to the failure-likely rotor (12), and the second supporting structure (4) is arranged on one end far away from the failure-likely rotor (12); the first supporting structure (3) and the second supporting structure (4) are connected through a connecting part (1).The cut-off apparatus is used for cutting off the connection of the first supporting structure with the second supporting structure via moving the connecting part from the connection position when failure of the failure-likely rotor (12) is caused, so that transmission of unbalanced load caused by rotor failure is avoided, and engine working reliability and security are ensured.
