Crossing and folding wing transmission device

Abstract

The invention relates to a crossing and folding wing transmission device which comprises a gear box body, missile wing main joints with teeth, a left missile wing, a right missile wing, half gears, a transmission gear, a driving gear set and a driving connecting rod, wherein two sides of the gear box body are provided with the missile wing main joints with teeth; sockets of the missile wing main joints with teeth are respectively connected with the left missile wing and the right missile wing; the lift missile wing is meshed with the transmission gear through the half gears of the missile wing main joints with teeth; the transmission gear is further meshed with a lower gear of the driving gear set; the right missile wing is meshed with an upper gear of the driving gear set through the half gears of the missile wing main joints with teeth; and power is transmitted to the driving connecting rod through a joint by a power source, further the driving gear set is driven, thus the synchronous rotation of the left missile wing and the right missile wing is realized. The crossing and folding wing transmission device has the advantages that the gear transmission device is modularized, the transmission is steady, and the impact force to an elastomer is tiny; the transmission gap and the clearance are less, during the process of the expanding of the missile wing and the changing of a sweep back angle, the synchronism is good, and the device has no locking action and no time delay.

Description

technical field [0001] The invention relates to a folding wing device, in particular to a cross folding wing transmission device. Background technique [0002] With the increasing complexity of the war environment, traditional missiles have exposed many defects due to their almost unchanged geometric shape, which are manifested in: the storage capacity of missiles per unit space is small, the ability to change attack targets is poor, and it is difficult to implement certain maneuvers at the end of the attack. Moreover, most of the current advanced long-range missiles have an inline shape and a large aspect ratio wing layout, which requires that the missile wings can be controlled in the initial stage, cruise stage, target search stage and terminal guidance stage, showing different aerodynamic shapes and structures. [0003] For the problem of small storage and transportation of missiles per unit of space, wing folding and unfolding technology has been adopted at home and abr...

AI Technical Summary

Problems solved by technology

[0003] For the problem of small storage and transportation of missiles per unit space, wing folding and unfolding technology has been adopted at home and abroad, but the specific content of the unfolding and folding mechanism has not been disclosed, and there are only two positions: fully folded and fully unfolded

The link mechanism generally used in China, because it needs to be attached with a separate locking mechanism, has no automatic unlocking function, and cannot be transformed into a continuously variable sweep angle; if there is a simple swing guide mechanism, each wing needs to be separated. The drive device is equipped with a separate mechanism, and the synchronization of the two wings is poor during the rotation process

Adaptive wing technologies such as the sliding skin and the hydraulic drive mechanism inside the wing to adjust the camber currently used by the aircraft are also due to the thin thickness of the airfoil of the missile wing, and there is no space for installation.
