(54) СПОСОБ ВЫБОРА ЖИДКИХ СМАЗОК ДЛЯ ПАР ТРЕНИЯ(54) METHOD FOR SELECTING LIQUID LUBRICANTS FOR FRICTION COUPLINGS
.; -;,Изобретение относитс к йспьггатёль- ной технике.:; - ;, The invention relates to an engineering technique .:
Известен способ выбора жидких дл пар трени смазок, заключающийс в том, что измер ют силу трени пары, трени при различных концентраци х жид- кой смазки 1J .,There is a known method of selecting lubricants that are liquid for friction steam, which consists in measuring the strength of a friction pair, friction at various concentrations of liquid lubricant 1J.,
Известный способ трудоемок.; The known method is labor intensive .;
Целью изобретени вл етс повьпие- ние производительности способа. The aim of the invention is to increase the productivity of the method.
Указанна цель достигаетс тем, что определ ют дл каждого материала пары трени косинус краевого угла смачивани , а выбор состава или концентрации смаз- . ки осуществл ют по минимальному зна-«/ чению суммы краевых углов смачивани .This goal is achieved by determining for each material of the friction pair the cosine of the wetting angle, and the choice of the composition or concentration of lubrication. The ki are performed at a minimum value - "/ to the sum of the wetting angle angles.
Способ осуществл ют следующим образом ..,The method is carried out as follows.
Определ ют косинус равновесного краевого угла смачивани cos 0 жидкой смаз-. кой поверхности образца по известной методике . Затем определ ют косинус равновесного краевого угла смачивани COSЭThe cosine of the equilibrium wetting angle, cos 0, is determined. sample surface by the known method. The cosine of the equilibrium wetting angle COSE is then determined.

жидкой смазки. Дл каждого состава смазки наход т сумму косинусов Ч (с) равновесных краевых углов смачивани смазкой поверхности образца и контр .liquid lubrication. For each lubricant composition, the sum of the cosines H (s) of the equilibrium wetting angle of the sample surface and the counter.
Величина f (с) , также как исоьО и 00502 вл етс функцией состава смазки , а также учитьшает взаимодействие смазки с поверхностью образца и с поверхностью контрьбразда. Затем наход$гг графическую зависимбсть суммы косинусов краевых углов смачивани V(c) от состава смазки, а выбор состава или концентрации смазки осуществл етс по минимальному значению суммы краевых углов смачивани .The value of f (c), as well as iso and 00502, is a function of the composition of the lubricant, as well as the interaction of the lubricant with the sample surface and with the counterbrace surface. Then the graphus dependence of the cosines of the wetting angle V (c) on the lubricant composition is found, and the composition or concentration of the lubricant is selected by the minimum value of the sum of the wetting angle angles.
