The invention discloses a rotorcraft transmission apparatus. The apparatus comprises a plurality of paddles, a rotor head, a gearbox body, a transmission mechanism, a main shaft and a shaft sleeve, wherein the rotor head is detachably connected with the end portion of each of the paddles; the edge position of the gearbox body is provided with a first mounting hole; the center position of the gearbox body is provided with a second mounting hole; the transmission mechanism comprises a transmission gear group and a first gear; the first gear is placed in the gearbox body; the transmission gear group is detachably connected with the gearbox body through the first mounting hole; the middle position of the outer wall of the transmission gear group is provided with an oblique gear; the oblique gear is engaged with a first gear; the shaft sleeve sleeves on the bottom of the main shaft; 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 gearbox body; and the end portion of the shaft sleeve is detachably connected with the gearbox body. The apparatus allows the first gear to drive the plurality of paddles to rotate through the main shaft, the shaft sleeve and the rotor head sequentially.
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...
