The invention discloses a transmission device of a rotorcraft, which comprises a plurality of propeller wings, a rotor head, a reduction box body, a transmission mechanism, a main shaft and a shaft sleeve, wherein the rotor head is detachably connected with the end part of each propeller wing; a first mounting hole is formed in the edge part of the reduction box body; a second mounting hole is formed in the center of the reduction box body; the transmission mechanism comprises a transmission gear bank and a first gear; the first gear is arranged in the reduction box body; the transmission gear bank is detachably connected with the reduction box body through the first mounting hole; a helical gear is arranged in the middle of an external wall of the transmission gear bank and meshed with the first gear; the bottom of the main shaft is sleeved with the shaft sleeve; the top end of the main shaft is detachably connected with the rotor head; the bottom end of the main shaft is detachably connected with the reduction box body; and the end part of the shaft sleeve is detachably connected with the reduction box body. According to the device, the propeller wings are driven to rotate by the first gear sequentially via the main shaft, the shaft sleeve and the rotor head.
Description
technical field [0001] The invention belongs to the technical field of mechanical transmission, in particular to a rotorcraft transmission device. Background technique [0002] In the 20th century, airplanes often stalled due to malfunctions during landing and landing, resulting in many deaths. Spanish engineer Sheba then invented the autogyro to try to solve this problem. When the rotor is moved by the aircraft, the airflow is aroused to rotate and generate lift, so that the aircraft will not fall when it stalls. At that time, his invention was called "windmill aircraft" by the press. Air Force base first official test flight. Three years later, in 1928, Sheba successfully crossed the English Channel in a gyroplane in 37 minutes. Since then, some companies in the United Kingdom and the United States have begun to manufacture rotorcraft for search and survey. In December 1936, Sheba was killed in the crash when his plane stalled and crashed while taking off from London's...
