Description

Technical Field

[0001] This utility model relates to the field of aviation aluminum sleeve technology, and in particular to an aviation aluminum sleeve with a safety limiting structure. Background Technology

[0002] In the fields of aerospace, precision instruments, and high-end equipment manufacturing, aviation aluminum sleeves are widely used in critical components such as hydraulic systems, transmission mechanisms, and structural supports due to their lightweight, high strength, and excellent corrosion resistance. However, aviation aluminum alloys are prone to plastic deformation or fatigue fracture under dynamic loads or extreme working conditions. Especially at the interface between the sleeve and shaft parts, the lack of an effective safety limiting structure may lead to loosening of the fit, axial movement, or even mechanical failure, thus causing significant safety hazards. Most sleeves rely solely on interference fits or threaded locking to achieve axial fixation, which is prone to fretting wear under long-term vibration or temperature changes, resulting in increased fit clearance. Therefore, we have redesigned an aviation aluminum sleeve with a safety limiting structure. Utility Model Content
