Description
Technical field
The invention belongs to tail-rotor spring bearing torsional rigidity test of vehicular technologies, are related to a kind of bearing product properties experimental rig.
Background technique
Tail-rotor spring bearing is the important load bearing component of helicopter tail rotor structure, is subjected to tail-rotor in tail-rotor structure and waves
Shimmy equal motive powers, complicated load condition when because of its work need to design special device for testing stiffness, test spring bearing
Performance indexes, it is ensured that its material and process condition.Tail-rotor spring bearing torsion stiffness test request spring bearing is in perseverance
Under fixed axial compression amount, applies load to it and then measure rigidity value.
Constant axial compression amount is all provided by Material Testing Machine in previous test, then applies radial load.Test needs
Material Testing Machine protects carry for a long time, higher to the stability requirement of equipment, while moves lever displacement by using turnbuckle
It is dynamic to reach its windup-degree.The error of test is larger and efficiency is lower.Therefore, a kind of tail-rotor support spring bearing torsion is invented
Device for testing stiffness can solve the above problem.
Summary of the invention
A kind of experimental rig is provided, tail-rotor spring bearing torsion stiffness test job can be completed.
A kind of tail-rotor spring bearing twisting property experimental rig, by support outline border, adjustable plate, rotary joint, spring bearing
Pressing plate and rotation center clamping plate composition；Support outline border is frame-type side hatch frame, has spring bearing in spring bearing mounting surface
The connecting hole of pressing plate, adjustable plate are rectangular slab, have the connecting hole of spring bearing pressing plate in the spring bearing mounting surface of adjustable plate, branch
Bearing plate is supportted as whole square structure, there is sliding slot on intermediate fluted structure, groove both sides, and rotation center clamping plate is rotation center
Symmetrical structure.When installation, first two pieces of spring bearing pressing plates, are passed through connection bolt respectively and are fixed on outside support by fixed support outline border
On frame and adjustable plate, it is bolted support outline border and adjustable plate by adjusting, then tail-rotor spring bearing is mounted in rotation
On heart clamping plate, two is fixed on, the spring bearing on fixed rotation center clamping plate is supported to be installed to support outline border and adjustable plate
On, rotary joint is connected on rotation center clamping plate, and rotary joint connects executing agency to apply test load.
The rotation center clamping plate is symmetrical structure, has rotation connecting hole in its two sides, two connecting holes are rotated about center
Axial symmetry.
The rotary joint is to connect rotation center folder by threaded hole in one end about rotation center symmetrical structure
Plate.
The adjustable plate adjusts the decrement of spring bearing as needed and by adjusting bolt.
The present invention realizes tail-rotor spring bearing torsion stiffness test job.Experimental rig controls tail-rotor by fixture itself
Spring bearing axial compression amount and use angular transducer and displacement sensor, improve the precision and working efficiency of test.
