Transmission efficiency is changed, in addition polygonal head transmitting driving end torque to driven end, stress surface is big, contact is steady.
In addition, the adaptive assembled multistage adjustable vane operating mechanism of the present invention is provided with lubrication on torque arm crossbeam
And wear-resistant coating, it is connected by the revolute pair that freedom degree is 1, prevents connecting rod from swinging, force drive end and at different levels driven
End can slide along torque arm crossbeam, be not only avoided because the connecting rod bring that swings interferes risk, and because of casing thermal deformation
Caused by power transmission lose, it is thus also avoided that bring is difficult to install due to the axial dipole field caused by machining tolerance.
It courts death described, the driven end of the adaptive assembled multistage adjustable vane operating mechanism of the present invention can be along torque arm cross
Beam sliding fix link assembly, gearing ring assemblies can with torque arm driven end in engine axis direction relative position always,
To improve power transmission efficiency, avoid interference with.Its drive end and the equal independent design of driven end at different levels, avoid certain level-one Rule adjusting
When changing, the case where needing replacing entire torque arm even more parts.Meanwhile torque arm drive end, driven end at different levels
Between angle it is adjustable, adapt to the variation that adjustable vanes at different levels adjust angles and range significantly.Driven ends at different levels are adaptively adjusted
Section is set, and is improved operating mechanism power transmission efficiency, is avoided interfering between part.Drive end at different levels, driven end can be individually replaced, and be fitted
Adjustable vanes at different levels are answered to adjust the variation of angle and range.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
Under the premise of from the principle and substance of the present invention, various changes or modifications can be made to these embodiments, but these are changed
Protection scope of the present invention is each fallen with modification.
