DEVICE FOR CONTROL OF ADHESION OF LIQUID LUBRICANT MATERIALS Russian patent published in 2016 - IPC G01N19/04 

FIELD: test devices.

SUBSTANCE: invention relates to investigation of materials, namely to devices for testing lubricants/oils with liquid or semi-liquid compositions. Knowledge of adhesion characteristics and properties of such types of lubricating media is very important for different engines lubrication systems of mechanical equipment, space systems and critical moving assemblies of special equipment operating under conditions of strongly varying temperature of both positive and negative. Device for control of adhesion of liquid lubricant materials includes drive for rotation of sample with lubricant, standard temperature and motor shaft speed control devices and scales. At that, in order to control adhesion properties of easily fluid lubricant materials not only in ordinary conditions of temperature, but at higher or lower, test sample contains horizontally positioned plate with controlled lubricant (oil/lubricant). At that, tray at its outer edge has circular bead with height of not more than two millimetres, which surface is hollow inclined to bottom of tray towards centre.

EFFECT: technical result is creation of device/device for control of adhesion properties of very fluid lubricants not only in ordinary conditions of temperature, but at higher or lower ones.
