Description

Изобретение относитс к области испытаний материалов на износ, в частности антифрикционных материаловThe invention relates to the field of testing materials for wear, in particular antifriction materials.

Цел11Ю изобретени вл етс повы- шение точности испытани за счет исключени вли ни погрешностей изготовлени элементов конструкции и их деформировани в ходе испытаний.The whole of the invention is to improve the accuracy of testing by eliminating the influence of errors in the manufacture of structural elements and their deformation during testing.

На чертеже представлено устройств дл испытани материалов на износ.The drawing shows devices for testing materials for wear.

Устройство содержит основание 1, держатель 2 контробразца 3, каретку 4 с образцом 5 материала, узел 6 нагру жени , датчик 7 линейного износа с упором 8, привод (не показан) вра- ще ни де ржа т ел 2.The device comprises a base 1, a holder 2 of a contra-edge 3, a carriage 4 with a sample 5 of the material, a loading unit 6, a linear wear sensor 7 with an emphasis 8, an actuator (not shown) of rotation orb 2.

Устройство снабжено второй кареткой 9, в которой выполнены три параллельных отверсти различного диаметра , соосньпс соответствующим отверсти м каретки 4. Меньшее отверстие предназначено дл размещени образца 10, датчик 7 закреплен в среднем отверстии каретки 4, упор 8 - в среднем отверстии каретки 9, а узел на- гружени закреплен в больших отверсти х кареток 4 и 9.The device is equipped with a second carriage 9, in which there are three parallel holes of different diameters coaxial with the corresponding holes of the carriage 4. The smaller hole is designed to accommodate sample 10, the sensor 7 is fixed in the middle hole of the carriage 4, the stop 8 is in the middle hole of the carriage 9, and the assembly the load is fixed in the large openings of the carriages 4 and 9.

Устройство работает следующим образом .The device works as follows.

Устанавливают образцы 5 и 10 в каретках 4 и 9, Привод т их в контакт с торцами контробразца 3 и нагружают с помощью узла 6 нагружени . В ходе испытани регистрируют износ с помощью датчика 7. При этом исключаетSamples 5 and 10 are installed in carriages 4 and 9, they are brought into contact with the ends of counter piece 3 and loaded using a loading unit 6. During the test, wear is recorded using sensor 7. This excludes

Invention Formula

A device for testing materials wearing a base mounted on it for rotation with its holder of a counterpiece and for moving the carriage parallel to the axis of the holder for accommodating a sample of the material, a unit and loading unit, a sample for linear wear of the sample and a rotational drive of the holder, characterized in that, in order to ensure the accuracy of the test, it is provided with a base mounted on the base that can be moved parallel to the axis The second carriage, designed to accommodate the second sample, has three parallel holes of different diameter coaxially corresponding to the corresponding holes of the other carriage, the smaller of which are used to place the sample; the linear wear sensor is fixed in the middle hole of the first carriage, its emphasis is on average the opening of the second carriage, and the loading unit is fixed in the large openings of both carriages.
