Problems solved by technology

However, it is difficult to finely control the opening angle of the air door by using the connecting rod mechanism; in the process of opening the air door, the force borne by the air door will all act on the motor through the connecting rod, which will cause great damage to the motor; and, Because the speed is too fast, the aviation winch will be impacted at the end of receiving and unwinding the cable, which will damage the components, reduce the service life, and have potential safety hazards; therefore, the existing air door opening mechanism needs to be improved urgently

Abstract

The invention discloses an aviation winch air door opening device. The aviation winch air door opening device comprises an air door arranged on a power cabin and an adjusting assembly used for adjusting the opening angle of the air door. A fixing support frame is arranged on a main shaft of the power cabin in a sleeving mode and is used as a basic installation component of the aviation winch air door opening device. A motor and the fixing support frame are fixedly connected through a motor gland; a magnetic hysteresis brake is arranged on the fixing support frame; the rotating speed and the torque of the motor are controlled through the magnetic hysteresis brake; an adjusting screw sleeve is arranged outside the motor in a sleeving mode; in addition, an adjusting screw nut is arranged on the adjusting screw sleeve; an air door connecting rod arranged on the adjusting screw nut is movably connected with the air door; and the adjusting screw sleeve is driven to rotate by an output shaftof the motor, so that the adjusting screw nut is driven to move horizontally, the air door connecting rod is driven to push the air door to open, and goal of precisely controlling the opening angle ofthe air door achieved.

Description

technical field [0001] The present disclosure generally relates to the technical field of aeronautical equipment, and in particular to an air door opening device for an aviation winch. Background technique [0002] The aviation winch is a rectifying nacelle suspended on the wing or belly of the aircraft, which is used to mount various types of towed targets and other equipment. [0003] At present, most of the existing mechanisms for opening the air door of the aviation winch adopt a motor-driven linkage mechanism to control the opening angle of the air door. However, it is difficult to finely control the opening angle of the air door by using the connecting rod mechanism; in the process of opening the air door, the force borne by the air door will all act on the motor through the connecting rod, which will cause great damage to the motor; and, Because the speed is too fast, the aviation winch will be impacted at the end of receiving and unwinding the cable, which will dama...
