Description
(54) ОБРАЗЕЦ ДЛЯ ИСПЫТАНИЯ МАТЕРИАЛОВ НА ИЗНОС(54) SAMPLE FOR WEAR MATERIAL TESTS
II
Изобретение относитс к образцам дл испытаний материалов трением и может быть использовано в качестве истигающего элемента в различных устройствах дл испытани на износ.This invention relates to samples for friction testing materials and can be used as an abatement element in various wear testing devices.
Известно применение абразивного материала Б качестве истирающего элемента при испытани х на износ 1.It is known to use abrasive material B as an abrasive element during wear tests 1.
Недостатком использовани абразивного материала вл етс невозможность точного определени нагрузок в контакте абразивное звено - испытуемый материал, поскольку не известно, сколько одновременно зерен контактирует с поверхностью и кака часть общей нагрузки приложена на каждое зерно.The disadvantage of using an abrasive material is the impossibility of accurately determining the loads at the contact of the abrasive element — the test material, since it is not known how many grains are in contact with the surface and what part of the total load is applied to each grain.
Известен образец дл испытани материалов на износ, содержащий держатель и пучок стержней 2.A known sample for testing materials for wear, comprising a holder and a bundle of rods 2.
Недостатком данного образца вл етс невозможность точного определени нагрузок в контакте стержень-испытуемый материал , что не дает возможности получатьThe disadvantage of this sample is the inability to accurately determine the loads in the contact rod-test material, which makes it impossible to obtain
достоверные результаты испытаний материалов при заданных нагрузках.reliable results of testing materials at given loads.
Целью изобретени вл етс повыщение достоверности результатов испытаний материалов на износ.The aim of the invention is to increase the reliability of the results of testing materials for wear.
Поставленна цель достигаетс тем, что держатель выполнен в виде обоймы, а стержни установлены в обойме с возможностью свободного перемещени относительно друг друга и относительно обоймы в осевом направлении. Кроме того, истирающа часть стержней выполнена многогранной.The goal is achieved by the fact that the holder is made in the form of a cage, and the rods are mounted in the cage with the possibility of free movement relative to each other and relative to the cage in the axial direction. In addition, the abrasive part of the rods is multi-faceted.
На чертеже изображен образец дЛ испытани материалов на износ.The drawing shows a sample dL of material testing for wear.
Образец выполнен в виде отдельных стержней 1, установленных свободно в обойме 2. Каждый стержень на конце имеет огранку , имитирующую абразивный материал. Образец взаи.модействует с испытуемым материалом 3. Давление в контакте стержень20 , испытуемый материал может быть получено под действием сил т жести стержней или приложением нагрузки к каждому из стержней отдельно.The sample is made in the form of individual rods 1, installed loosely in the cage 2. Each rod at the end has a cut, imitating abrasive material. The sample interacts with the test material 3. The pressure in the contact rod 20, the test material can be obtained under the action of the force of gravity of the rods or by applying a load to each of the rods separately.
