Изобретение относитс к испытательным машинам дл изучени трени при низких температурах.This invention relates to testing machines for studying friction at low temperatures.
По основному авт. CR: № 263243 известно устройство дл изучени трени в крио генных жидкост х, содержащее криостат с размещенным в нем узлом трени , кинематически св занный через редуктор с электроприводом, измерительную штангу с грузами, магнитной муфтой и динамометром , а также консольный диск, несущий кольцевой образец, причем измерительна щтанга укреплена в подшипниках скольжени промежуточной опоры соосно с держателем образца 1.According to the main author. CR: No. 263243, a device for studying friction in cryogenic liquids is known, which contains a cryostat with a friction unit located in it, kinematically connected through an electric gearbox, a measuring rod with weights, a magnetic coupling and a dynamometer, and also a cantilever disk carrying an annular sample The measuring bar is fixed in the sliding bearings of the intermediate support coaxially with the sample holder 1.
Недостатком этого устройства вл етс то, что оно не обеспечивает достаточно высокой точности определени параметров трени при изменении температуры, когда имеет место переход смазочного сло в сверхпровод щее состо ние.A disadvantage of this device is that it does not provide a sufficiently high accuracy in determining the parameters of friction with a change in temperature when a transition of the lubricating layer to the superconducting state takes place.
Цель изобретени - повышение точности оценки параметров трени .The purpose of the invention is to improve the accuracy of the evaluation of friction parameters.
Поставленна цель достигаетс за счет того, что устройство снабжено токосъемником с разделенными попарно токовыми и потенциальными контактами, установленным с возможностью перемещени параллельно оси вращени держател образца. На чертеже схематически изображено устройство.This goal is achieved due to the fact that the device is equipped with a current collector with current and potential contacts separated in pairs, installed with the possibility of moving parallel to the axis of rotation of the sample holder. The drawing schematically shows the device.
Оно содержит криостат 1, вращающий5 с держатель 2 образца 3, выполненный в виде шестерни, привод держател образца , состо щий из электродвигател 4, редуктора 5, вала 6 и шестерни 7, держатель 8 контробразца 9, сменные грузы 10,It contains a cryostat 1, rotating 5 with the holder 2 of the sample 3, made in the form of a gear, the drive of the sample holder consisting of the electric motor 4, the gear 5, the shaft 6 and the gear 7, the holder 8 of the counterpiece 9, interchangeable loads 10,
,- магнитную муфту 11, тензометрический динамометр 12, установленные на крышке 13, стойку 14,промежуточную опору 15, датчик 16 температуры, герметический токоввод 17, термокамеру 18, хладопровод 19, а также токосъемник, состо щий из щтока, - magnetic coupling 11, strain gauge dynamometer 12 mounted on the lid 13, stand 14, intermediate support 15, temperature sensor 16, hermetic current lead 17, heat chamber 18, cold pipe 19, as well as a current collector consisting of a stem
15 20, микрометрического винта 21 и контактов 22.15 20, micrometer screw 21 and pins 22.
Устройство работает следующим образом .The device works as follows.
Образец 2 закрепл ют на вращающемс держателе 2, а контробразец 9 - на Sample 2 is mounted on a rotating holder 2, and counterpiece 9 is mounted on
20 держателе 8, нагружают пару трени сменными грузами 10 и включают привод держател образца. Силу трени измер ют с помощью тензометрического динамометра 12. Температуру в зоне трени поддер20 holder 8, load a pair of friction interchangeable loads 10 and include the drive holder sample. The strength of the friction is measured using a strain gauge dynamometer 12. The temperature in the friction zone is supported
