Abstract
Изобретение относитс к исследованию сопротивл емости материалов истиранию при трении по нежестко закрепленной абразивной прослойке и может быть использовано исследовательскими организаци ми в качестве экспресс- метода испытани материалов. Цель изобретени - повышение точности при испытани х по незакрепленному абразиву за счет стабилизации процесса попадани абразивных частиц и параметров шероховатости контртела. Прижимают эластичный цилиндр по образующей этой поверхности к плоскому контртелу, задают относительное планетарное движение абразива и контробразца, вращают образец вокруг оси и подают в зону трени абразивные частицы.The invention relates to the study of the resistance of materials to abrasion by friction on a loosely fixed abrasive layer and can be used by research organizations as a rapid method for testing materials. The purpose of the invention is to improve the accuracy of the tests on the loose abrasive due to the stabilization of the process of hitting the abrasive particles and the roughness parameters of the counterbody. Press the elastic cylinder along the generatrix of this surface to the flat counterbody, set the relative planetary motion of the abrasive and counter sample, rotate the sample around the axis and feed the abrasive particles into the friction zone.
Description
Изобретение относитс к исследованию сопротивл емости материалов истиранию при трении по нежестко закрепленной абразивной прослойке и может быть использовано исследовательскими организаци ми в качестве экспресс-метода испытаний материалов .The invention relates to the study of the resistance of materials to abrasion by friction on a loosely fixed abrasive layer and can be used by research organizations as a rapid method for testing materials.
Цель изобретени - повышение точности при испытани х по незакрепленному абразиву за счет стабилизации процесса попадани абразивных частиц и параметров шероховатости контртела.The purpose of the invention is to improve the accuracy of the tests on the loose abrasive due to the stabilization of the process of hitting the abrasive particles and the roughness parameters of the counterbody.
Способ реализуетс следующим образом .The method is implemented as follows.
Испытывают плоский контробразец и цилиндрический эластичный контробразец, который прижимают к контробразцу боковой поверхностью цилиндра, задают им относительное планетарное перемещение.A flat contra-sample and a cylindrical elastic contra-test are tested, which are pressed to the counter-probe with the lateral surface of the cylinder, and they are given relative planetary displacement.
вращают образец вокруг оси цилиндрической поверхности и подают в зону трени абразивные частицы. После испытани оценивают износостойкость материалов.rotate the sample around the axis of the cylindrical surface and feed abrasive particles into the friction zone. After testing, the durability of the materials is evaluated.
Возможен вариант, когда образцу дополнительно задают возвратно-поступательное движение вдоль оси цилиндрической поверхности .It is possible that the sample is additionally given a reciprocating motion along the axis of the cylindrical surface.
Пример. Использовали плоский и круглый контробразец, изготовленный из закаленной стали, которому задавали вращени вокруг оси со скоростью 40 об/мин и вокруг некоторого центра со скоростью 5 об/мин, удаленного на 20 мм от этой оси. Прижимали к контробразцу резиновый ролик , который вращали со скоростью 700 об/мин вокруг оси, и подавали в зону контакта кварцевый песок фракционного состаVIExample. A flat and round contra-edge made of hardened steel was used, which was set to rotate around an axis at a speed of 40 rpm and around a center at a speed of 5 rpm 20 mm away from this axis. A rubber roller was pressed to the counter piece, which was rotated at a speed of 700 rpm around the axis, and quartz sand of fractional composition was fed into the contact zone.
