Abstract
A kind of hyperbola multidiameter shaft of the utility model is related to airplane component field, more particularly to multi-rotor unmanned aerial vehicle field, in particular to a kind of hyperbola multidiameter shaft, including shaft body, the both ends of the shaft body are respectively axis big end and axis small end, the diameter of axis big end is greater than the diameter of axis small end, and from axis big end to axis small end, the diameter of axle successively decreases.The diameter of the utility model axis big end is greater than the diameter of axis small end, is the variable diameter axis of cone, and performance is most steady reliable, meet it is high-speed rotating over long distances steadily and power output reliable performance, mechanism vibration is small, run smoothly, when high speed rotation, axial runout is small.
Description
Technical field
The utility model relates to airplane component fields, and in particular to multi-rotor unmanned aerial vehicle field, in particular to it is a kind of double
Curve multidiameter shaft.
Background technique
During developing synchronizer, in order to guarantee that engine power is steadily output to the propeller of distal end, guarantee high speed
Rotary shaft smooth rotation, it is necessary to select a kind of reliable long axis.By many experiments, we use its property of the hyperbola variable diameter axis of cone
Can be most steady reliable, meet it is high-speed rotating over long distances steadily and power output, reliable performance, mechanism vibration is small, runs smoothly.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of hyperbola multidiameter shaft, and concrete scheme is as follows:
A kind of hyperbola multidiameter shaft of the utility model, including shaft body, the both ends of the shaft body be respectively axis big end and
Axis small end, the diameter of axis big end are greater than the diameter of axis small end, and from axis big end to axis small end, the diameter of axle successively decreases.
Preferably, its axis is provided with several shaft shoulders in shaft body, the distance between adjacent shaft shoulder is equal.
Preferably, the distance between two neighboring shaft shoulder is 10-15cm.
Preferably, the shaft body between the two neighboring shaft shoulder is provided with an arc-shaped ring groove, the central axis of the arc-shaped ring groove
Line and the central axis of shaft body are on the same line.
Preferably, the shaft section intersection of arc-shaped ring groove and shaft body is one section of camber line, and the both ends of camber line are apart from shaft body
Central axis is equidistant, and is all larger than arc centers point at a distance from shaft body central axis.
Preferably, which is used for driven helicopter and multi-rotor aerocraft.
The diameter of the utility model axis big end is greater than the diameter of axis small end, is the variable diameter axis of cone, performance is most steady reliable, full
Steadily and power output reliable performance, mechanism vibration is small apart from high-speed rotating for foot length, runs smoothly, axial when high speed rotation
It beats small.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the partial enlarged view of A in Fig. 1.
Appended drawing reference: 1- shaft body, 2- axis big end, 3- axis small end, the 4- shaft shoulder, 5- arc-shaped ring groove.
Specific embodiment
The utility model includes shaft body 1, and the both ends of the shaft body 1 are respectively axis big end 2 and axis small end 3, axis big end 2
Diameter be greater than the diameter of axis small end 3, and from axis big end 2 to axis small end 3, the diameter of axle successively decreases.
Its axis is provided with several shaft shoulders 4 in shaft body 1, the distance between adjacent shaft shoulder 4 is equal.
The distance between two neighboring shaft shoulder 4 is 10-15cm, which can be set to 11cm.
Shaft body 1 between the two neighboring shaft shoulder 4 is provided with an arc-shaped ring groove 5, the central axis of the arc-shaped ring groove 5 with
The central axis of shaft body 1 on the same line, the setting of arc-shaped ring groove 5, so that the utility model is in high-speed rotation process
Centrifugal force reduces, and increases centripetal force, and then reduce the utility model amplitude of fluctuation, increases the stationarity of rotation.
The shaft section intersection of arc-shaped ring groove 5 and shaft body 1 is one section of camber line, and the both ends of camber line are apart from 1 center of shaft body
Axis is equidistant, and is all larger than arc centers point at a distance from 1 central axis of shaft body.
The hyperbola multidiameter shaft is used for driven helicopter and multi-rotor aerocraft.
In use, the utility model is used for power transmission in driven helicopter and multi-rotor aerocraft, and then drive spiral
Paddle rotation, since revolution speed of propeller is higher, and power transmission distance is farther out, and the utility model is chosen suitably according to actual needs
Length, and the diameter of axis big end 2 is greater than the diameter of axis small end 3, guarantees high-speed rotating shaft smooth rotation；The utility model performance is flat
It is steady reliable, meet it is high-speed rotating over long distances steadily and power output, reliable performance, mechanism vibration is small, runs smoothly.
