Shake and displacement motion, and transmit and centrifugal force load of the balance from blade.
Center piece as helicopter structure key component, fatigue behaviour is one important indicator, it is necessary to carried out
Fatigue test, obtains the fatigue rupture pattern and tired weak part of bearingless rotor main hub center piece, is
Initial lifetime evaluation provides foundation.
The main oar center piece of conventional bearing-type rotor is ring-like support arm structure, the fatigue experimental device of design be
Resilient bearing central point on support arm be mounted directly wave, shimmy and centrifugal force component carries out three-dimensional loading.And
The main oar center piece of bearingless rotor is fork ear type support arm, and space is small, support arm is weak, it is difficult to directly pacified on support arm
Dress three-dimensional charging assembly.Therefore, for the main oar center piece fatigue test of bearingless rotor, its installation need to be simulated
When stress, design a set of new three-dimensional loading device, examine its fatigue behaviour.
At present, China does not have similar experimental rig, it is impossible to carry out this loading.Not retrieving abroad has
The open source literature of pass.
The content of the invention
The technical problem to be solved in the present invention：There is provided a kind of helicopter bearing-free tail rotor main oar center piece three-dimensional
Loading device, stress when simulation center piece is installed, testing stand stabilization can apply to wave to center piece
Power, shimmy power and centrifugal force, reach the purpose of examination center piece fatigue behaviour.
Technical scheme：A kind of main oar center piece three-dimensional loading device of bearingless rotor, including by waving
Bearing adapter sleeve is waved, bearing pressure ring is waved, is waved bearing holder (housing, cover), wave roller bearing, wave limiting plate and wave
What dance joint was constituted waves loading adapter assembly, waves loading adapter assembly by hinged with flexible beam bogusware
Connection, the load that direction is waved in realization to main oar center piece support arm applies；By shimmy bearing adapter sleeve, shimmy
The shimmy of bearing pressure ring, shimmy bearing holder (housing, cover), shimmy roller bearing, shimmy limiting plate and shimmy joint composition adds
Adapter assembly is carried, shimmy loading adapter assembly is realized in main oar by the hinged connection with flexible beam bogusware
The load of central member support arm edgewise direction applies；By locking nut, centrifugal force joint, bolt and steel wire rope are constituted
Centrifugal force loading adapter assembly, centrifugal force load adapter assembly by the threaded connection with flexible beam bogusware,
Realize applying the load of main oar center piece support arm centrifugation force direction.
Described three-dimensional loading device includes waving charging assembly, shimmy charging assembly and centrifugal force charging assembly,
Wave charging assembly and wave direction arrangement along flexible beam bogusware, shimmy charging assembly is along the shimmy side of flexible beam bogusware
To arrangement, centrifugal force charging assembly is axial arranged along flexible beam bogusware, and each component layout points do not interfere with each other, real
Existing mutually perpendicular three-dimensional loading.
Described three-dimensional loading device, to wave and contain roller bearing in charging assembly and shimmy charging assembly, tries
When testing, wave and form hinged connection with the loading of edgewise direction, reduce additional moment, improve and wave
With the loading accuracy of shimmy power.Meanwhile, wave limiting plate and shimmy limiting plate serve prevent from waving with it is shimmy
The play of load(ing) point, it is ensured that wave constant with shimmy loading position and direction.In centrifugal force charging assembly
Locking nut prevents centrifugal force to load the loosening of joint, and steel wire rope is connected with centrifugal force joint by bolt
Connect, centrifugal force is loaded along steel wire rope direction.
Breakthrough is difficult to directly be installed on main oar center piece support arm the technical barrier of three-dimensional charging assembly, by soft
Property beam bogusware center piece is applied to wave power, shimmy power and centrifugal force, simulate the main oar center piece of bearingless rotor
Stress, reaches the purpose of examination center piece fatigue behaviour.
