Problems solved by technology

For some places where the space of the aircraft is narrow, due to the irregular deformation of the flexible cable / pipe when it rotates around the axis, if the gap between the flexible cable / pipe and the rotating shaft is small, it is easy to cause the cable / pipe to be out of alignment during the movement. Interference of structure / mechanism, causing abrasion of cables / pipes

Abstract

The invention relates to an interference prevention structure of a pipeline and a rotating shaft. The interference prevention structure comprises a rotating part, a rotating shaft, a fixing part, a flexible cable / pipeline, first equipment, a baffle plate, a clamp hoop and second equipment. The interference prevention structure constrains a deformation route of the flexible cable / pipeline passing through the rotating shaft in a rotating process; a gap between the flexible cable / pipeline and the rotating shaft in the rotating process can be ensured; and the flexible cable / pipeline only bears buckling motion, so that abrasion caused by back-and-forth friction between the flexible cable / pipeline and the structure is reduced.

Description

technical field [0001] The invention relates to the field of installation of aircraft equipment pipelines, in particular to an anti-interference structure for pipelines and rotating shafts. Background technique [0002] In order to improve the combat capability of modern fighter jets, some electronic products are usually arranged inside some rotating parts. The electronic products will move together with the rotating parts. The movement of the rotating parts usually rotates around a certain axis. The cables / The tubing will also rotate around this axis, so cables / pipes are usually chosen to be flexible cables / pipes that can withstand bending back and forth. For some places where the space of the aircraft is narrow, due to the irregular deformation of the flexible cable / pipe when it rotates around the axis, if the gap between the flexible cable / pipe and the rotating shaft is small, it is easy to cause the cable / pipe to be out of alignment during the movement. Structure / mecha...
