Problems solved by technology

If the hydraulic actuator is used for lifting, firstly, it must solve the load and lock when the hydraulic actuator is raised, and secondly, solve the problem that various lines are not well arranged during the lifting process.
If the four-bar linkage bracket is used, the space is not enough
If the chain lift is used, it is also limited by space and weight

Abstract

The invention provides an elevating mechanism for an aircraft radome. The elevating mechanism is arranged in a support (2) and comprises a ball screw tooth cover (3), a ball screw (4), a speed reducer(5), a hydraulic motor (6), and a coupling assembly (7), wherein the ball screw tooth cover (3), the speed reducer (5) and the hydraulic motor (6) are arranged on a lower reinforcement rib (12); thehydraulic motor (6) is connected with one end of the speed reducer (5), and the other end of the speed reducer (5) is connected with the ball screw tooth cover (3) through the coupling assembly (7); the hollow ball screw (4) is sleeved inside the ball screw tooth cover (3); the ball screw (4) is sleeved by a flange sleeve (10) which is connected with the upper reinforcement rib (11); and the hydraulic motor (6) drives the ball screw (4) to straightly move up and down so as to change the height of the radome (1). The elevating mechanism provided by the invention is simple in structure, controllable in elevating speed and good in force transmission characteristics, and the screw is hollow and thus allows various cables to pass through.

Description

technical field [0001] The invention belongs to the field of aircraft radome, and in particular relates to an aircraft radome lifting mechanism. Background technique [0002] In order to make the aircraft height conform to the upper limit of the aircraft carrier hangar, as well as the restrictions of the hangar door, upgrade ladder, maintenance in the hangar, etc., the radome must be kept as far away from the fuselage as possible during flight to avoid the obstruction of the radar vision by the fuselage. A hydraulic lifting device is designed so that the radome can be lowered to a certain height when entering the gate and storing. [0003] The aircraft radome lifting mechanism is due to the height restriction of the aircraft carrier hangar, and the radome must be designed to be liftable so that the aircraft can be parked in the hangar. When the aircraft is in normal use, the radome must be raised to a specific height to ensure that the antenna has a sufficient downward view...
