Description
(54) УСТРОЙСТВО ДЛЯ ИСПЫТАНИЯ УПЛОТНИТЕЛЬНЫХ ЭЛАСТИЧНЫХ ЭЛЕМЕНТОВ(54) DEVICE FOR TESTING SEALING ELASTIC ELEMENTS
II
Изобретение относитс к уплотнительной технике и может быть использовано дл оценки свойств материала уплотнительных элементов.The invention relates to a sealing technique and can be used to evaluate the material properties of sealing elements.
Известно устройство дл испытани j в. частности, уплотнительных элементов , выполненное в виде нескольких измерительных секций, кажда из которых .включает узел начальной деформац и в виде двух колец, между которыми располагают испытываемый элемент. Кольца через подшипники св заны с опорными дисками, один из которых сообщен с приводом вращени .A device for testing jc is known. in particular, sealing elements, made in the form of several measuring sections, each of which includes an initial deformation unit and in the form of two rings, between which the test element is placed. The rings are connected through bearings to bearing discs, one of which is in communication with a rotating drive.
.Устройство также имеет средство дл Периодической дополнительной деформации уплотнительного элемента в виде установленных под определенmsH углом относительно оси вращени опорных подшипников, и динамометр, измер ющий силу треки в опорных подшипниках, вл ющуюс мерой жест кости издели . Это устройство выбрано в качестве прототипа СО .The device also has a means for periodically additional deformation of the sealing element in the form of an angle determined by the MSH angle relative to the axis of rotation of the support bearings, and a dynamometer measuring force tracks in the support bearings, which is a measure of the stiffness of the product. This device is selected as a prototype.
Недостатком этого устройства вл етс то, что результаты измерени невозможно соспоставить со стан- дартньии характеристиками материала, например модулем упругости при сжатии . При стандартном испытании к любой точке опорной поверхности образца прикладываетс одинакова нагрузка , т.е.- поверхности, сжимающие образец, перемещаютс параллельно A disadvantage of this device is that the measurement results cannot be matched with the standard material characteristics, for example, the compressive modulus. In the standard test, the same load is applied to any point of the sample surface, i.e. the surfaces compressing the sample move in parallel
0 друг другу, а в прототипе нагрузка, вызывающа дополнительную деформацию образца, неравномерно распределена по опорной поверхности образца, т.к. дополнительна деформаци обеспечи15 ваетс перекатьшанием. Кроме того, устройство не позвол ет определ ть в одном испытании релаксацию напр жени , что не дает возможность точ- но учитывать изменение жесткости.0 to each other, and in the prototype the load causing additional deformation of the sample is unevenly distributed over the reference surface of the sample, since additional deformation is provided by redrafting. In addition, the device does not allow one to determine stress relaxation in one test, which does not allow one to accurately take into account the change in stiffness.
