Taking this as a prelude to a more detailed description discussed later.
In consideration of it, there is damage combustion gas wheel to solve to carry out disk-bursting test directly on gas turbine in the present invention
The risk of machine, and then devise a kind of rotation test device for the verifying of combustion engine wheel disc brake test.
Scheme adopted by the present invention are as follows: a kind of rotation test device for the verifying of combustion engine wheel disc brake test, the rotation
Turning experimental rig includes whirling test stand, test wheel disc, clamp force nut, double end clamp force screw rod, loading blocks, ring flange, fixed spiral shell
Bolt and stud；
The whirling test stand includes bottom plate, rotary shaft and support tube, and rotary shaft, support tube and rotation is arranged in the center of bottom plate
Shaft is coaxially disposed, and circumferentially offers multiple mounting holes on support tube；The test wheel disc gap package on the rotary shaft, and is tried
Wheel disc is tested to be fixed in the rotary shaft of whirling test stand by ring flange, fixing bolt, stud；Loading blocks are mounted on test
In the tongue-and-groove of wheel disc；Double end clamp force screw rod passes through mounting hole, and loading blocks are fixed in one end, and the other end is fixed on by clamp force nut
On the support tube of whirling test stand；Loading blocks are applied with certain load by tightening clamp force nut；Whirling test stand is in motor
It is rotated under drive with given rotating speed.
Further: the load block size with test that test the corresponding blade root of wheel disc consistent；Test wheel disc size and reality
Border wheel disc is consistent.So set, test result is more acurrate.
Further: the mounting hole, loading blocks, double end clamp force screw rod number are consistent with the test tongue-and-groove number of wheel disc.
So set, experimental rig is more stable.
Further: the double end clamp force screw rod applies the size that magnitude of load is equal to blade centrifugal force under specified revolving speed.
Further: the internal diameter of the mounting hole is greater than the outer diameter of double end clamp force screw rod.So set, guaranteeing testing
After journey tongue-and-groove is broken, loading blocks are radially unfettered.
Further: the outboard sidewalls of the support tube establish connection by floor and bottom plate.So set, floor plays
Increase the effect of whirling test stand rigidity.It avoids that whirling test stand deformation is made to cause shadow to disk-bursting test since revolving speed is excessively high
It rings.
Further: the bottom plate, rotary shaft and support tube are integrally machined molding.So set, increasing rotation test
The intensity of platform.It avoids impacting whirling test stand deformation to disk-bursting test.
Present invention effect achieved are as follows:
Rotation test device of the invention, at low cost, structure is simple, easily operated.It avoids being tried using gas turbine
Test the risk for causing damage.
