Abstract

The invention discloses a coaxial helicopter lift system. The system comprises a shell. The side wall of the shell is rotationally connected with a power shaft. The end part of the power shaft is in key connection with a first bevel gear. The upper end and the lower end of the first bevel gear are in engaged transmission connection with a second bevel gear and a third bevel gear correspondingly. The first bevel gear, the second bevel gear and the third bevel gear are all located in the shell. The center of the second bevel gear is in key connection with a first rotating shaft. A lower rotor head is fixed in the middle of the first rotating shaft, and the center of the third bevel gear is in key connection with a second rotating shaft, the second rotating shaft penetrates through the interior of the first rotating shaft and extends to the upper end of the first rotating shaft, an upper rotor head is fixed to the end of the upper end of the second rotating shaft, paddle clamps are symmetrically installed on the two sides of the upper rotor head and the two sides of the lower rotor head. The structure is simple, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of helicopter lift systems, and in particular relates to a coaxial helicopter lift system. Background technique [0002] As one of the unique creations of aviation technology in the 20th century, the helicopter has greatly expanded the application range of aircraft. Helicopters are typical military-civilian dual-use products, which can be widely used in transportation, patrol, tourism, rescue and other fields. Maneuverable flight with constant head direction, especially for vertical take-off and landing on small-area sites. Because of these characteristics, it has broad application and development prospects. [0003] The lift system of the helicopter is divided into two types: single-screw and double-screw. The dual-screw coaxial helicopter has the advantages of short rotor arm span, low power consumption, no need to install the tail rotor to balance the reaction torque generated by the rotor rotation, and...
