Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.But, those skilled in the art are it should also be understood that the invention is not restricted to listed detailed description of the invention, as long as meeting the spirit of the present invention, all should be included in protection scope of the present invention.
Referring to accompanying drawing 1.Material sample plane contact friction performance testing device of the present invention is mainly used in the test of material friction performance, the sample 7 that uses, grind away product 8 is lamellar, it is possible to for disk, it is also possible to be other shape.
Sample 7 is fixedly mounted on the side of sample base 1, grind away product 8 is fixedly mounted on to mill sample base 2 side；Sample 7 and two planes of grind away product 8 are installed in opposite directions, and the sample 7 and contact plane of grind away product 8 is perpendicular to horizontal plane；Put on the power that power F is horizontal direction to grind away product 8 and be perpendicular to the plane to grind away product 8.So that tight fit between sample 7 and pedestal, attaching one layer of sample pad on sample base surface, sample pad preferentially selects CuCrZr material to make.
It is applied to the horizontal thrust F to grind away product 8 to be transmitted by forcing shaft 6.Forcing shaft 6 is arranged on the opposite side to mill sample base 2, the axis of forcing shaft 6 is perpendicular to the plane to grind away product 8, it is sphere that forcing shaft 6 protrudes the one end to mill sample base 2, when applying power F, can make grind away product 8 micromotion in process of friction and wear, make grind away product 8 are better contacted with to mill sample base 2.Mill sample base 2 is fixedly mounted on the pedestal 11.
Base 11 has the track 9 parallel with sample 7 plane, for reducing the frictional force that in sample 7 motor process, the abrasion of non-sample produces.The power f that sample base 1 moves along track is provided by actuating system, for sample in process of the test 7 and to the relative movement between grind away product 8.
Sample 7, to grind away product 8 are separately installed with temperature sensor 4, can sample 7 and the variations in temperature to grind away product 8 in experiment with measuring process promptly and accurately.Sample base 1 is also equipped with displacement and force transducer 5, can the frictional force in experiment with measuring process in real time, and then the size of coefficient of friction can be drawn.
Material sample plane contact frictional behaviour can be tested by another embodiment of the present invention under the vacuum condition of liquid nitrogen temperature, said structure is basically unchanged, by sample base 1 and the body structure that mill sample base 2 is made to sealing, sample base 1 and to mill sample base 2 be welded by high heat conduction, high-strength material and solder, it is preferred to CuCrZr and Ag56 is welded.Being respectively mounted liquid nitrogen ascending pipe 3 and liquid nitrogen discharge pipe 10 at sample base 1 with to the top of mill sample base 2, it is temperature required that liquid nitrogen circulation can make test environment reach.Then by sample base 1, being arranged in vacuum chamber to mill sample base 2, base 11 therein can be the bottom of vacuum chamber.
It should be noted that above-described embodiment is exemplary rather than the restriction present invention, those skilled in the art will can design a lot of alternate embodiment right without deviating from this patent.
