Description

Изобретение относится к испытанию смазочных материалов и оценке вида . изнашивания рабочих поверхностей узлов трения машин и механизмов.The invention relates to the testing of lubricants and assessment of the type. wear of the working surfaces of the friction units of machines and mechanisms.

Цель изобретения - повышение достоверности способа за счет учета, действия нерастворимых примесей в масле.The purpose of the invention is to increase the reliability of the method by taking into account the action of insoluble impurities in oil.

На чертеже представлены результаты оценки вида изнашивания поверхностей трения,.The drawing shows the results of an assessment of the type of wear of the friction surfaces.

Способ оценки вида изнашивания поверхностей трения осуществляется следующим образом.The method of assessing the type of wear of the friction surfaces is as follows.

Эксплуатируют смазанную пару трения. ’В ходе эксплуатации берут пробы, работавшего масла, подвергают их фотометрированию и определяют оптическую плотность, характеризующую количество общих примесей Д в масле. Затем пробу делят на две части. Одну из них испытывают на машине трения с определением площади S пятен износа поверхностей трения. Вторую часть пробы подвергают центрифугированию, после чего верхний слой масла повторно фотометрируют и определяют оптическую плотность, характеризующую влияние растворимых примесей Др. Затем находят величину Д/ = Д - Др, характеризующую влияние нерастворимых примесей. Строят зависимостьExploited lubricated friction pair. 'During operation, samples are taken of the working oil, they are subjected to photometry and the absorbance is determined, which characterizes the amount of total impurities D in the oil. Then the sample is divided into two parts. One of them is tested on a friction machine with the determination of the area S of wear spots of friction surfaces. The second part of the sample is subjected to centrifugation, after which the upper layer of oil is re-photometric and the optical density characterizing the influence of soluble impurities Dr. is determined. Then find the value D / = D - D p characterizing the influence of insoluble impurities. Build Addiction
