Abstract

The invention provides a sphere connection compensation device for an aircraft fuel system. The compensation device comprises a first structural body with a sphere part, a second structural body witha mounting port for mounting the sphere body, a first sealing ring and a second sealing ring arranged in a gap between the sphere part and the mounting port, and a limiting ring for limiting movementof the first sealing ring and the second sealing ring and contacted with the sphere part to enable the first structural body and the second structural body to relatively rotate, wherein the section diameters of the first sealing ring and the second sealing ring are different; and the positions of the limiting ring and the second structural body are relatively fixed. The sphere connection compensation device enables the sphere structure to rotate in all directions to prevent vibration and other influences on an aircraft along with various attitude angles, stress application, takeoff and landingof the aircraft in the full-envelope process of the aircraft.

Description

technical field [0001] The present application belongs to the technical field of machinery, and particularly relates to a spherical connection compensation device used in an aircraft fuel system. Background technique [0002] According to the needs of tasks and functions, a special form of connection mechanism is often required in the aircraft structure, with a spherical connector as the main body, combined with a sealing ring on the outlet housing for fuel delivery. However, the traditional connector compensation mechanism has a regular shape and cannot be rotated. Under the complex conditions of aircraft use, the stress at the connection is superimposed, resulting in damage or fatigue fracture, which cannot be applied to the entire aircraft envelope. [0003] Therefore, a new form of connection mechanism is required to meet the functional requirements of the all-inclusive wire. SUMMARY OF THE INVENTION [0004] The purpose of the present application is to provide a ball...
