Folding mechanism suitable for folding morphing wing

Abstract

The invention provides a folding mechanism suitable for a folding morphing wing. The folding mechanism has the characteristics of lower driving torque and modularization in installation and maintenance. The folding mechanism comprises a sun wheel shaft (1), a gear ring (2), a planet wheel bearing (3), a planet wheel (4), a hinge shell (5), a gear box sealing cover (6), a planet carrier shaft (7),a hinge bearing (8), an oil-proof cover (9), a planet carrier (10), a sun wheel shaft bearing (11), a dust cover (12) and an outer sleeve (13). According to the folding mechanism, a planet gear systemis adopted, torque is transmitted through a gear meshing higher pair, and the driving torque of the mechanism for achieving the folding action is reduced by utilizing the characteristic of high reduction ratio of the planet gear system. When the wing load is large, the load of each folding mechanism can be reduced in the mode that a plurality of folding mechanisms are connected in parallel. The folding mechanism has the advantages of easiness in installation, the compact structure, large torque and high adaptability and is suitable for wings of various kinds of shipboard aircraft and foldingmorphing aircraft.

Description

technical field [0001] The invention relates to a folding mechanism suitable for folding modified wings. Background technique [0002] For traditional aircraft, it is difficult to achieve both excellent low-speed flight performance and high-speed flight performance. The working environment of high-speed aircraft has high dynamic pressure, so it does not need a large wing area and wing thickness to maintain flight. In order to reduce drag, high-speed aircraft usually have a smaller aspect ratio, lower wing thickness, and the leading edge of the wing is mostly pointed to reduce shock wave resistance; while low-speed aircraft have low dynamic pressure in the working environment to ensure lift , a wing with a relatively large aspect ratio and a relatively thick wing is required to ensure that the aircraft has a large wing area and a large lift coefficient. [0003] The folding wing variant aircraft is a variant aircraft that significantly changes the effective area of ​​the wi...

Problems solved by technology

Actuators for wing folding can be divided into mechanical actuators, memory alloy actuators, and piezoelectric actuators. Among them, mechanical actuators are relatively mature and widely used in carrier-based aircraft wing folding machines. However, these mechanisms The load-bearing capacity is poor, and the coupling with the wing structure is serious, which is not conducive to the maintenance and replacement of the mechanism
