Embodiment Construction

[0011] figure 1 The two middle rotors are connected by the tilting shaft 5, and the tilting mechanism is installed in the middle of the fuselage, and its internal structure is shown in the figure. Worm wheel 1 links to each other with tilting shaft 5, is fixed by screw. The worm screw 2 is driven by the steering gear 6, and the two ends are supported by bearing blocks 9. The swivel 3 is connected with the tilting shaft 5 and fixed by screws. The pull rod 8 connects the angle sensor 7 and the swivel 3, the tilting shaft 5 drives the angle sensor 7 to rotate through the swivel 3 and the pull rod 8, and the angle sensor 7 feeds back the deflection angle to the control circuit in the form of an electrical signal. The assembly relationship of the whole tilting mechanism is as shown in the figure, the tilting shaft 5 is connected to the mounting frame 10 through the bearing 4, and the worm bearing seat 9 is fixed on the lower surface of the mounting frame 10 with bolts.

Abstract

The invention relates to a tilting mechanism, a running mode of the tilting mechanism, and the application of the tilting mechanism in a tilting rotorcraft, belonging to the technical field of tilting mechanisms. The tilting mechanism drives a tilting shaft to tilt by using a steering engine through a worm gear device, and guarantees the tilting shaft after tilting is stabilized on a preset position by using the self-locking characteristics of the worm gear device in the process of rotation. The tilting mechanism is provided with a feedback loop, the tilting shaft is provided with a rotation ring, the rotation ring is connected with one end of a draw bar, and the other end of the draw bar is connected with an angular transducer; the rotation shaft of the angular transducer and the tilting shaft rotate synchronously, and the angular transducer transfers tilting angles into electrical signals and then provides the electrical signals for a control system so as to realize feedback control.

Description

[0001] Technical field [0002] The invention relates to a tilting mechanism, its working method and its application on a tilting rotorcraft, and belongs to the technical field of tilting mechanisms. Background technique [0003] The tilting mechanism is an angle adjustment mechanism. For example, cranes, car steering wheels, etc. all use different types of tilting mechanisms. The common mechanical tilting device uses a motor to directly drive the tilting shaft to rotate. Although this method is simple and practical, the operation accuracy is not high, and the tilted position is easily affected by external disturbances and deviates from the predetermined position, making it difficult to maintain stability. For technical fields that require precise control, it is difficult for the commonly used tilting mechanism to meet the requirements. For example, the tilt rotor aircraft is a new type of aircraft that combines the advantages of fixed-wing aircraft and helicopters. The de...
