Abstract

The invention relates to the technical field of a high-speed helicopter and provides a double-engine input coaxial double-rotor main speed reducer and an aircraft. The double-engine input coaxial double-rotor main speed reducer comprises a first rotor assembly and a second rotor assembly, wherein a first gear set is used for driving the first rotor assembly to rotate, a second gear set is used fordriving the second rotor assembly to rotate, a torque dividing gear set is used for providing driving force for the first gear set and the second gear set, a power input assembly is used for providing the driving force for the torque dividing gear set, a tail output assembly is used for outputting the power, a power input assembly transmits power to the torque dividing gear set and further transmits the power to the first gear set and the second gear set so that the first rotor assembly and the second rotor assembly can rotate, and the rotating speed of the first rotor assembly and the rotating speed of the second rotor assembly are the same and opposite in direction.

Description

technical field [0001] The invention relates to the technical field of high-speed helicopters, in particular to a dual-engine input coaxial dual-rotor main reducer and an aircraft. Background technique [0002] The main reducer is a key component of the helicopter transmission system. Traditional helicopters adopt a single-rotor with tail rotor layout. The main reducer has many configurations and is relatively mature in technology. Therefore, the structure of the main reducer is more complicated than that of the single-rotor main reducer, and the design is more difficult. Coaxial twin-rotor helicopters can be divided into types without a tail rotor and with a tail rotor. The former is mainly used to eliminate the rotor reaction torque and make the helicopter fuselage shorter; in addition to eliminating the rotor reaction torque, the tail rotor can also provide thrust , so that the helicopter can fly at high speed. At present, the main reducer with dual-engine input and coax...
