Description
щие через ролики 7-9 соответственно с ползуном 2 и коромыслом 4, узел 1О нагружени , плунжер 11, соединенный при помощи шарнира 12с коромыслом 4, установленный в плунжере вал 13 с держателем 14 образца и маховичком 15, снабженным выступами 16, флажок 17, бункер 18 дл абразива, заслонка 19, фиксатор 2О. Устройство работает следующим образом. В начале рабочего хода ползуна 2 приводимого кулачком 5 кулачок 6 опускает коромысло 4 и вместе с ним п унжер 11с валом 13 и образцом до соприкосновени последнего с исгираю щим элементом 3. Затем осуществл етс трение образца по истирающему элемент В конце рабочого хода флажок 17,взаимодейству с выступами 16 на маховичке, проворачивает образец относительно свое оси, который фиксируетс упругим фикса тором 2О. При обратном ходе ползуна к лачок 6 поднимает коромысло 4, вывод тем самым из взаимодействи образец и флажок 17. При исследовании абразивног износа абразив автоматически подаетс из бункера 18 при помощи заслонки 19, закрепленной на ползуне 2.through the rollers 7-9, respectively, with the slider 2 and the yoke 4, the loading unit 1O, the plunger 11, connected with the help of the hinge 12c by the rocker 4, the shaft 13 installed in the plunger with the sample holder 14 and the handwheel 15 fitted with lugs 16, the flag 17, the bunker 18 for abrasive, damper 19, latch 2O. The device works as follows. At the beginning of the working stroke of the slider 2 driven by the cam 5, the cam 6 lowers the rocker arm 4 and together with it the cam 11c with the shaft 13 and the sample until the latter touches the deflecting element 3. Then, the sample is rubbed over the abrading element. At the end of the stroke, the flag 17 interacts with the protrusions 16 on the handwheel, rotates the sample about its axis, which is fixed by the elastic fixator 2O. During the return stroke of the slider, the slider 6 lifts the beam 4, thereby withdrawing the sample and the flag 17 from the interaction. When studying abrasive wear, the abrasive is automatically fed from the hopper 18 by means of a shutter 19 attached to the slider 2.
