Abstract | The invention relates to a cyclic variable-pitch screw rod dustproof device for a helicopter, in particular to a protective device capable of achieving the purpose of preventing dust from falling into a cyclic variable-pitch screw rod at the bottom of a helicopter cockpit. The cyclic variable-pitch screw rod dustproof device is one of important parts of a helicopter flight control system. The cyclic variable-pitch screw rod dustproof device is used for realizing component sealing of the cyclic variable-pitch screw rod in the cockpit and preventing the situation that as the dust falls into the cyclic variable-pitch screw rod at the bottom of the helicopter cockpit in the daily flight process, the clamping stagnation of a fright control cabling system is caused. The invention provides the cyclic variable-pitch screw rod dustproof device which is brief in structure, attractive in appearance and convenient to maintain, has a new structure and is made of new materials.
