Description
(54) УСТАНОВКА ДЛЯ ИЗУЧЕНИЯ ФРИКЦИОННЫХ СВОЙСТВ МАТЕРИАЛОВ(54) INSTALLATION FOR THE STUDY OF THE FRICTION PROPERTIES OF MATERIALS
1one
Изобретение относитс к области измерительной техники.The invention relates to the field of measurement technology.
Известны установки дл изучени фрикционных свойств материалов, состо щие из платформы, закрепленной на основании одним концом с возможностью изменени угла наклона, установленной на платформе подложки с исследуемым образцом, механизм определени коэффициента трени которого выполнен в виде транспортира дл измерени угла поворота платформы 1.Installations are known for studying the frictional properties of materials consisting of a platform fixed on the base at one end with the possibility of changing the angle of inclination mounted on the platform of the substrate with the sample under test, the mechanism for determining the coefficient of friction of which is designed as a protractor for measuring the angle of rotation of the platform 1.
Недостатком таких установок вл етс невысока точность при измерении угла между платформой и горизонтальной плоскостью и, как следствие, невозможность исследовани случаев движени с малыми коэффициентами трени .The disadvantage of such installations is the low accuracy in measuring the angle between the platform and the horizontal plane and, as a consequence, the impossibility of investigating cases of movement with low coefficients of friction.
Целью изобретени вл етс повышение точности и обеспечение измерений малых значений коэффициента трени при скольжении и качении.The aim of the invention is to improve the accuracy and ensure the measurement of small values of the coefficient of friction during sliding and rolling.
Цель достигаетс тем, что механизм определени коэффициента трени выполнен в виде измерител времени от начала изменени угла наклона платформы до начала движени по ней исследуемых образ2The goal is achieved by the fact that the mechanism for determining the coefficient of friction is made in the form of a time meter from the beginning of a change in the angle of inclination of the platform to the beginning of movement along the studied image
цов, при этом установка снабжена механизмами включени и отключени измерител времени, срабатывающими соответственно один - в момент.начала изменени угла наклона платформы, а другой - в момент начала движени исследуемого образца по платформе.The installation is equipped with mechanisms for switching on and off the time meter, which are triggered, respectively, at the moment of the beginning of the platform tilt angle change, and the other at the moment of the beginning of movement of the test sample on the platform.
На чертеже показана схематично установка .The drawing shows a schematic installation.
Установка состоит из платформы 1, способной поворачиватьс вокруг неподвижной горизонтальной оси 2, двигател 3 с редуктором 4, измерител времени 5 и автоматических средств - средства запуска 6 и средства остановки 7. Вс установка помещена в термокамеру, позвол ющую проводить исследовани в интервале температур от комнатной до -Ь50°С.The installation consists of a platform 1 capable of turning around a fixed horizontal axis 2, an engine 3 with a gearbox 4, a time meter 5 and automatic means - starting means 6 and a means of stopping 7. The entire installation is placed in a heat chamber that allows studies in the temperature range from room temperature. to -50 ° C.
Установка работает следующим образом .The installation works as follows.
К платформе 1 прикрепл етс подложка , на которую устанавливаютс образцы „ исследуемого материала. Двигатель 3 через редуктор 4 приводит во вращение платформу 1 с посто нной угловой скоростью и). Измерение угла ot между платформой 1 иA support is attached to the platform 1 on which the samples of the test material are placed. Motor 3, through gearbox 4, drives platform 1 at a constant angular velocity and). Ot angle measurement between platform 1 and
