Description
камере 1 с помощью стакана И. На элементах 10 размещены датчики 12 (например тензосопротивлени ), подсоединенные к шлейфовому осциллографу (на чертежах не показан). Узел регистрации деформации и сближени образцов включает расположенный в окне держател 4 рычаг 13, на один конец которого опираетс стержень 14, а другим концом взаимодействующий с датчиком 15. Последний закреплен в рамках 16 и 17, жестко соединенных с планкой 18, перемещение которой осуществл етс с помощью микровинта 19. Привод 7 вращени образца 3 содержит вал 20 и зубчатые колеса 21 и 22, последнее размещено на держателе 2. Механизм 6 нагружени содержит передачу гайка - винт (не показан на чертеже), взаимодействующий с нагрузочным винтом динамометр 23, который опираетс на держатель - шток 2. Держатель 2 размещен и проходит через двустенный цилиндр 24 и траверсу 25. Устройство снабжено сильфоном 26, сохран ющим герметичность камеры 1, снабженной дверью 27. Дл измерени температуры образца 5 используетс термопара 28.chamber 1 with glass I. Sensors 12 are placed on elements 10 (for example, strain resistances) connected to a loop oscilloscope (not shown in the drawings). The node for detecting the deformation and approaching of the samples includes a lever 13 located in the holder 4, the rod 14 is supported at one end, and the other end interacts with the sensor 15. The latter is fixed within 16 and 17 rigidly connected with the rod 18, which moves with using a microscrew 19. The actuator 7 for rotating the sample 3 contains the shaft 20 and gears 21 and 22, the latter is placed on the holder 2. The loading mechanism 6 contains a nut-screw transmission (not shown in the drawing) interacting with a dynamo loading screw 23, which rests on the holder - rod 2. The holder 2 is placed and passes through the double-wall cylinder 24 and the cross member 25. The device is equipped with a bellows 26, which keeps the chamber 1 tight, equipped with a door 27. A thermocouple 28 is used to measure the temperature of the sample 5.
Устройство работает следующим образом .The device works as follows.
В держатель 4 вставл ют образец 5, сквозь последний пропускают стержень 14. В отверстие держател 2 устанавливают образец 3. С помощью винта 19 через планку 18, рамки 16 и 17 и рычаг 13 привод т в соприкосновение с образцом 3 стержень 14. Закрывают дверь 27 и с помощью насоса 29 создают в камере 1 давление до 10 н/м. Использованием жидкого азота и водорода давление в камере довод т доSample 5 is inserted into the holder 4, the rod 14 is passed through the latter. Sample 3 is inserted into the opening of the holder 2. Using screw 19, bar 18, frames 16 and 17 and lever 13 bring the rod 14 into contact with sample 3. Close the door 27 and with the help of pump 29, pressure up to 10 n / m is created in chamber 1. Using liquid nitrogen and hydrogen, the pressure in the chamber is adjusted to
н/м. Привод т во вращение образец 5 и нагружают его. Сигналы сближени образцов температурной деформации и момента трени записывают на ленте осциллографа. n / m Sample 5 is rotated and loaded. The signals of approaching the samples of temperature deformation and the moment of friction are recorded on the oscilloscope tape.
