A clapboard type feedback steel cable structure with a copper inner sleeve

Abstract

The invention relates to a clapboard penetrating type feedback steel cable structure with copper linings. The clapboard penetrating type feedback steel cable structure comprises a clapboard I, a compression nut, a front casing pipe, a lining, a front draw bar, a steel cable inner core, an additional nut, a flat nozzle, a conduit, a rear casing pipe, another lining, a rear draw bar, nuts, a locking ring and a clapboard II, wherein the front casing pipe penetrates through the clapboard I to be fixed by the compression nut, the copper lining is assembled in the front casing pipe in an interference mode, the front end of the front casing pipe is closed up to prevent the copper lining from separating in operation, the copper lining is assembled in the rear casing pipe in an interference mode, the front end of the rear casing pipe is contracted to prevent the copper lining from separating in operation, external threads of the steel cable inner core are screwed to the bottoms of holes of the front and rear draw bars to be assembled into a steel cable inner core assembly, the additional nut, the flat nozzle, the conduit and the rear casing pipe are welded into a steel cable casing assembly, and the rear draw bar penetrates the clapboard II to be installed by the nuts and the locking ring. The clapboard penetrating type feedback steel cable structure has the advantages of being reliable in operation, adaptable to a clapboard structure and capable of realizing the connection of steel cables. According to the clapboard penetrating type feedback steel cable structure, the abrasion problem of the draw bars can be efficiently solved when the steel cables are used.

Description

technical field [0001] The invention relates to the field of aero-engines, and in particular provides a clapboard-passing feedback steel cable structure with a copper inner sleeve. Background technique [0002] Aeroengine control system is an important part of the engine, and it is the key to ensure the engine to realize its function, performance and reliability. The development of the control system is very important to the development of the entire engine. The control of the engine is realized by controlling the adjustable variables such as the angle of the guide vane, the amount of fuel, and the angle of the nozzle, so as to meet all the control functions required by the engine and ensure the normal operation of the engine within the flight envelope. Generally, engines with mechanical hydraulic control systems use feedback cables to convert angle displacements into linear displacements to realize the transmission of guide vane angles and nozzle angles to control accessori...

AI Technical Summary

Problems solved by technology

[0004] Since the connecting parts at both ends of the feedback cable are movable parts, it is unavoidable that the angle deflection at the connecting end of the cable sometimes occurs during work, so problems such as wear and tear of the connecting parts may occur during work, which reduces the reliability of the cable
