Abstract

The invention provides a tilting transmission device for fixing an engine, and belongs to the technical field of design of a rotor wing system of a helicopter. The tilting transmission device comprises a fixed end and a tilting end, the fixed end comprises the engine and a second bevel gear meshed with a first bevel gear on the end portion of a first output shaft of the engine, the tilting end comprises a third bevel gear coaxial with the second bevel gear and a fourth bevel gear meshed with the third bevel gear, and a third output shaft connected with the fourth bevel gear drives a propellerto rotate. A control mechanism controls the tilting end to rotate, so that the third output shaft can be converted into a second state from a first state, in the first state, the axis of the third output shaft is parallel to the direction of a longitudinal shaft of the helicopter to achieve forward light, and in the second state, the axis of the third output shaft is parallel to the direction of aperpendicular shaft of the helicopter to achieve lifting. According to the tilting transmission device, tilting of a rotor wing of the propeller is away from the engine so that the engine can be fixed relatively, and difficulty of design and evidence taking of the engine is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of helicopter rotor system design, in particular to an engine-fixed tilt transmission device. Background technique [0002] The tiltrotor is a unique aircraft, which not only has the vertical take-off and landing and air hovering capabilities of ordinary helicopters, but also can cruise and fly like propeller aircraft. When the plane of rotation of the propeller rotor is parallel to the plane of the fuselage, the aircraft is in helicopter mode and can perform vertical take-off and landing or short-distance take-off and landing; when the plane of rotation of the propeller rotor is perpendicular to the plane of the fuselage, the aircraft becomes In the fixed-wing aircraft mode, the lift of the aircraft is provided by the fixed wings. At this time, the aircraft can fly forward at a high speed. [0003] At present, the tilt rotor mechanism can be divided into two modes: the propeller rotor tilts and the fixed w...
