Комплексный автоматизированный метод выявления дефектов колец подшипников

Abstract

В работе рассмотрен комплексный автоматизированный метод выявления дефектов колец подшипников качения колесной пары вагона на основании ультразвукового и виброакустического методов неразрушающего контроля. Основной целью разрабатываемого метода является возможность проведения экспресс-оценки состояния колец в условиях железнодорожных ремонтных предприятий с целью разбраковки неремонтопригодных и восстановления путем шлифования поверхностного слоя подшипника качения. Описаны алгоритмы предлагаемых методов и работа системы, включающей в себя оба метода. Результатом работы такой системы является получение пользователем отчета о состоянии кольца: является ли он дефектным или нет, размере дефекта, его координатах, глубине залегания. При этом поиск дефектов происходит в два этапа. На первом этапе производится виброакустическая диагностика кольца. Время, затрачиваемое на его проведение, составляет порядка 10 секунд. Результатом является заключение о наличии, либо отсутствии дефекта в кольце. Второй этап заключается в проведении ультразвукового контроля, на который затрачивается около 5 минут. При наличии дефекта результатом являются его характеристики: размер, координаты, глубина залегания. При отсутствии подтверждение виброакустического метода. Таким образом, производится подтверждение одного метода другим.

In work the complex automated method of detection of defects of rings of rolling bearings of wheel couple of car on the basis of ultrasonic and vibroacoustic methods of nondestructive control is considered. Main objective of a developed method is possibility of carrying out an express assessment of a condition of rings in the conditions of railway repair shops for the purpose of grading not maintainable and restoration by repolishing. Algorithms of offered methods and work of the system including both methods are described. Receiving by the user of the report on a condition of a ring is result of work of such system: whether it is defective or not, the extent of defect, its coordinates, a depth. Thus search of defects happens in two stages. At the first stage vibroacoustic diagnostics of a ring is made. Time spent for its carrying out, makes about 10 seconds. The conclusion about existence, or lack of defect in a ring is result. The second stage consists in carrying out ultrasonic control for which about 5 minutes are spent. With defect its characteristic are result: size, coordinates, depth. At absence confirmation of a vibroacoustic method. Thus, confirmation of one method by another is made.
