Description
Technical field
The present invention is a kind of device for the bearing wear test, belongs to the technical field of structures of product.
Background technology
At present, the light materials such as AIRFLON of oscillating bearing widespread use in the aircraft takeoffs and landings frame system are made liner or are directly used lighter AIRFLON lining, but because the import gasket material is obstructed, oscillating bearing, lining etc. are supply shortage often.Because gasket material is the critical function material of bearing, lining, so adopt oscillating bearing, the lining of homemade gasket material production need carry out a series of polishing machine test.
The domestic present Kazakhstan of having only that can carry out the bearing wear test flies design experiment chamber and Shanghai bearing research institute.And the low-temperature condition test realizes that difficulty, the real-time monitoring of testpieces wear extent, the peace control protection of testpieces etc. are still the important difficult problem that this project faces.Simultaneously, existing equipment has test complicated, and the cost of equipment maintenance height is unfavorable for the energy-saving and cost-reducing deficiency that waits.
Summary of the invention
The present invention designs at above-mentioned the deficiencies in the prior art just provides a kind of device for the bearing wear test, its objective is the real-time monitoring that realizes the testpieces wear extent, the high and low temperature state test can be carried out, the test condition of major diameter testpieces can be satisfied.
The objective of the invention is to be achieved through the following technical solutions:
This kind is used for the device of bearing wear test, it is characterized in that: this device comprises a two fork base (1), bearing test spare (2) is installed on two fork bases (1) by mandrel (3), fit with loading monaural (4) in bearing test spare (2) top, load monaural (4) and load that pressurized strut (6) is connected and by loading pressurized strut (6) bearing test spare (2) is applied radially pressure at right angle downwards, in the said modules laying temperature chamber (8);
Mandrel (3) is connected with swing pressurized strut (10), swing pressurized strut (10) drives the crankmotion that mandrel (3) is done ± 25 degree angles, load monaural (4) and be provided with wearing and tearing displacement transducer (5) and power sensor (7) with the connecting link that loads pressurized strut (6), wearing and tearing displacement transducers (5) are by measuring the attrition value that the shift value that loads pressurized strut (6) reacts bearing test spare (2), power sensor (7) is used for the power loaded value that feedback loads pressurized strut (6), mandrel (3) is provided with torque sensor (9) and limit sensors (11), torque sensor (9) is used for the torque value of feedback oscillating pressurized strut (10), and limit sensors (11) is controlled the anglec of rotation of mandrel (3) by the rotation distance of measuring mandrel (3).
Adopted precision to reach ± 0.2% wearing and tearing displacement transducer (5) displacement transducer in the technical solution of the present invention, by the displacement measurement that loads pressurized strut (6) being realized the real-time monitoring of the wear extent of bearing test spare (2), solved and had only test to finish the problem that just can check the testpieces wear extent, simultaneously peace control value is set in the swing pressurized strut (10) on wear extent and the mandrel (3), reaching excessive can the stopping of certain wear extent or moment of torsion tests, avoid that the test specimen wear extent is excessive to damage, reached the purpose of security control.Realized more harsh high and low temperature state test by temperature test chamber (8), solved the low-temperature condition difficult problem of lowering the temperature, the low-temperature condition test temperature can be reduced to-45 ℃, guarantees that simultaneously low-temperature condition is stable, error is at ± 5 ℃, and this device has also been realized the test to the major diameter testpieces.
