Figure.
Fig. 2 is the moving ring assembly structural schematic diagram of embodiment illustrated in fig. 1 of the present invention.
Fig. 3 is the propeller hub installation diagram that the support arm of embodiment illustrated in fig. 1 of the present invention is arranged at 30 °.
Fig. 4 is the propeller hub installation diagram of the support arm arrangement at 45 ° of embodiment illustrated in fig. 1 of the present invention.
Specific embodiment
The present invention is further explained below by way of specific embodiment.
Conventional auto-bank unit can only meet a kind of propeller hub configuration, in order to overcome this deficiency, invent a kind of multi-fork
The new type auto inclinator of ear rotating ring form can adapt to the propeller hub configuration of diversified forms.
With reference to Fig. 1, which mainly includes that moving ring assembly 1, moving ring assembly 2, big flexural pivot component 3, displacement are not drawn
Bar assembly 4, torsional arm component 5, the flat key 6 for playing anti-torque arm and guide tube 7 form.Moving ring assembly is the key that portion of the present invention
Part.Moving ring assembly 2 has 8-12 fork ear 21, as shown in Fig. 2, the fork ear number of rotating ring is determined according to practical situation, it is different
The fork ear combination of (30 °, 45 °, 60 °, 90 °) of available multiple angles arrangements is combined with each other between fork ear.
By taking 10 fork ear rotating ring auto-bank units as an example, give how the auto-bank unit realizes 30 °, 45 °, 60 ° of arrangements
Scissors propeller hub: assuming that auto-bank unit be mansion depending on rotate counterclockwise, from Fig. 2 positive direction of the x-axis be pitch ear 1, rotate counterclockwise
To fork 10 (not shown) of ear, wherein to the right along x-axis, fork ear 4 is upward along y-axis for fork ear 1, and fork ear 6 to the left, pitches ear 9 along x-axis
It is downward along y-axis, as such, it will be understood that fork ear 1 pitches ear 4 to the fork each fork ear interval of ear 6 to fork each 30 ° of the fork ear interval of ear 4
45 °, fork ear 6 to fork each 30 ° of the fork ear interval of ear 9, fork ear 9 to fork each 45 ° of the fork ear interval of ear 1, based between these fork ears
Interval degree, propeller hub can be made to be combined into a variety of arrangement modes.
As shown in figure 3, the scissors propeller hub that support arm is arranged at 30 °: fork ear 1 and fork ear 5 connect torsional arm component, fork ear 3, fork
Ear 4, fork ear 8, fork ear 9 install pitch-change-link component, wherein at fork ear 4 and fork ear 9 the pitch-change-link other end connects is low
Position propeller hub support arm, fork ear 3 with pitch at ear 8 pitch-change-link connect is high-order propeller hub support arm, 8 be wherein high position propeller hub in Fig. 3,
That is the first propeller hub, 9 be low level propeller hub, i.e. the second propeller hub.
The scissors propeller hub that support arm is arranged at 60 °: installation is similar to the scissors propeller hub that 30 degree are arranged, fork ear 1 and the fork connection of ear 5
Torsional arm component, selection pitch ear 2, fork ear 4, fork ear 7, fork ear 9 and connect pitch-change-link component, wherein pitching ear 4 and pitching the change at ear 9
What it is away from the connection of the pull rod other end is low level propeller hub support arm.
As shown in figure 4, the scissors propeller hub of support arm arrangement at 45 °: due to aerodynamic effects, low level propeller hub support arm must move ahead,
The propeller hub need to change the installation site of toggle, mount scheme when arranging are as follows: fork ear 4 and fork ear 9 install torsional arm component, pitch ear
1, pitch-change-link is installed at fork ear 5, fork ear 6 and fork ear 10, wherein what fork ear 4 was connected with the pitch-change-link other end at fork ear 9
It is low level propeller hub support arm.
The invention has the advantages that when changing the height of high-low-position propeller hub support arm, it is only necessary to change the length of pitch-change-link
Degree can be suitble to；It can be suitble to the propeller hub of support arm arrangement in 90 °.
The auto-bank unit smart structural design of multi-fork ear rotating ring form need to only change pitch-change-link and the anti-torque arm of toggle
Installation site can meet 30 °, 45 °, 60 ° and 90 ° arrangement propeller hub configurations.
