Problems solved by technology
[0002] The vertical lift and low-altitude civil rotorcraft is a small low-altitude civilian aircraft. The reducer is often used in the rotorcraft for power transmission. Since the volume of the vertical lift and low-altitude civil rotorcraft is relatively small, the ordinary reducer will occupy a large space, thereby reducing The normal use volume of the vertical lift and low-altitude civil rotorcraft is reduced, and the utilization rate of the vertical lift and low-altitude civil rotorcraft is reduced

The invention provides a vertical lift low altitude civil rotorcraft reducer structure, which is simple in structure, and is capable of effectively reducing the size of a reducer and better improving the utilization rate of a vertical lift low altitude civil rotorcraft. The vertical lift low altitude civil rotorcraft reducer structure comprises an output shaft and an input shaft, wherein the input shaft is connected with a change gear shaft by first variable gears; the change gear shaft is connected with the output shaft by second variable gears. The vertical lift low altitude civil rotorcraft reducer structure is characterized in that one end of the output shaft and one end of the input shaft are provided with a sleeve shaft each; a sleeve shaft variable gear is arranged on each sleeve shaft; the change gear shaft is provided with variable gears which are engaged with the sleeve shaft variable gears.
Description
technical field [0001] The invention relates to the technical field of rotorcraft, in particular to a structure of a speed reducer for vertical lifting and lowering civil rotorcraft. Background technique [0002] The vertical lift and low-altitude civil rotorcraft is a small low-altitude civilian aircraft. The reducer is often used in the rotorcraft for power transmission. Since the volume of the vertical lift and low-altitude civil rotorcraft is relatively small, the ordinary reducer will occupy a large space, thereby reducing The normal use volume of the vertical lift-off civil rotorcraft has been reduced, and the utilization rate of the vertical lift-down civilian rotorcraft has been reduced. Contents of the invention [0003] In view of the above problems, the present invention provides a vertical lift and lower civil rotorcraft reducer structure, which has a simple structure, effectively reduces the volume of the reducer, and can better improve the utilization rate of...
