Description
) УЗЕЛ ТРЕНИЯ ДЛЯ ИСПЫТАНИЯ ЖИДКИХ СРЕД НА АБРАЗИВНОСТЬ ПРИ ТРЕНИИ КАЧЕНИЯ 1 . Изобретение относитс к испытани м материалов трением и может быть использовано при испытании на абразивность масел, смазочно-охлаждаю| |их жид костей, буровых и других растворов. Известен узел трени дл испытани жидких гре на абразивность, содержащий чашу, расположенные в ней три сферических образца и пуансон со сферическим наконечником, взаимодействующий с образцами С } Недостатком известного узла трени вл етс высокий коэффициент проскаль зывани образцов, что искажает резуль тать испытаний из-за изнашивани образцов как за счет скольжени , так. и за счет качени . Извстен узел трени дл испытани жидкиХ сред на абразивность при трении- качени , содержащий подшипник качени с расположенными между телами качени разделительными элементами. Разделительные элементы выполнены в виде перемычек сепаратора подшигтниKaD . Недостатком известного устройства вл етс то, что в процессе работы абразив забивает зазор между телами качени и пepeмычkaми сепаратора.,, вызыва повышенный износ тел качени от трени скольжени . Это снижает достоверность результатов испытаний жидких сред на абразивное гь при треНИИ качени . Целью изобретени вл етс повышение достоверности результатов испытаний за счет уменьшени -величины проскальзывани тел качени относительно абразива среды. Поставленна цель достигаетс тем, что в узле трени дл испытани жидких сред на эбрази&ность при тре НИИ качени , содержащем подшипник качени с расположенными между телами качени разделительными элементами , разделительные элементы выпол) KNOTE OF FRICTION FOR TESTING LIQUID MEDIA FOR ABRASIVENESS IN THE FRICTION OF QUALITY 1. The invention relates to the testing of materials by friction and can be used when testing the abrasiveness of oils, lubricant cooling | | their fluid bones, drilling and other solutions. A known friction unit for testing grit abrasiveness, containing a bowl, three spherical specimens in it and a spindle with a spherical tip that interacts with specimens C} sample wear due to slip as well. and by rolling. A friction assembly is wound to test fluid friction for rolling friction, comprising a rolling bearing with spacer elements disposed between the rolling bodies. The separating elements are made in the form of KaD separator jumpers. A disadvantage of the known device is that in the process of operation, the abrasive clogs the gap between the rolling bodies and separator barriers, causing an increased wear of the rolling bodies from sliding friction. This reduces the reliability of the results of tests of liquid media on abrasive gf at rolling TRAIN. The aim of the invention is to increase the reliability of the test results by reducing the amount of slip of the rolling bodies relative to the abrasive of the medium. This goal is achieved by the fact that in a friction unit for testing liquid media for ebrasion # at a rolling research institute, containing a rolling bearing with spacers located between the rolling bodies
