Description
(54) ОБРАЗЕЦ ДЛЯ ОПРЕДЕЛЕНИЯ АДГЕЗИОННОЙ ПРОЧНОСТИ СОЕДИНЕНИЯ НА СДВИГ Изобретение относитс к испытательной т&книке, а именно к образцам дл определени адгезионной прочности соединени на сдвиг. Известен образец дл испытани на сдвиг, выполненный в виде двух тонкостен ных втулок, причем на наружной втулке выполнены равномерно расположенные по окружности отверсти дл нанесени испытуемого покрыти Ll. Наиболее близким к предлагаемому вл етс образец дл определени адгезионной прочности соединени на сдвиг, выполненный в виде охватываемой и охватывающей втулок, на цилиндрической поверхности сопр жени которых нанесен адгезив 2 . Недостатком известных образцов вл етс низка точность определени адгезионной прочности при испытании из-за неравномерности нагружени сло адгезнва , котора приводит к постепенному разрушению этого сло , начина от его внешней кромки. Цель изобретени - повышение точности определени адгезионной прочности при испытании. Поставленна цель достигаегс тем, что внутренн поверхность охватываемой и наружна поверхность охватьшающей втулок до их поверхностей сопр жени выполнены коническими так, что сечени втулок имеют форму пр моугольных треугольников , сопр гаемые катеты которых имеют одинаковую длину, вершины конусов лежат по одну сторону от втулок, а величины конусности выбраны из соотношени ,.b.,o. - величины конусности охватываемой и охватывающей втулок соответственно; г - внутренний радиус охватываемой втулки;(54) SAMPLE FOR DETERMINING ADHESIVE STRENGTH OF CONNECTION ON SHIFT The invention relates to a test book, namely, samples for determining the adhesion strength of a shear joint. A known test specimen for shear, made in the form of two thin-walled bushings, with evenly circumferential apertures for applying the test coating Ll on the outer bushing. Closest to the present invention is a sample for determining the adhesive strength of a shear joint, made in the form of male and female sleeves, on the cylindrical interface of which adhesive adhesive 2 is applied. A disadvantage of the known samples is the low accuracy of the adhesion test when tested due to the uneven loading of the adhesive layer, which leads to the gradual destruction of this layer, starting from its outer edge. The purpose of the invention is to improve the accuracy of determining adhesion strength when tested. The goal is achieved by the fact that the inner surface of the male and the outer surface of the covering sleeves to their mating surfaces are made conical so that the sections of the sleeves have the shape of right-angled triangles whose matching legs have the same length, the tops of the cones lie on one side of the sleeves, and taper values are selected from the ratio, .b., o. - the taper values of the male and female sleeves, respectively; g - the inner radius of the covered sleeve;
