лении с шагом, равным диаметру проволоки. В результате получают предварительно напр женную пружину, перевитую в обратном наиравлении, витки которой плотно поджаты один К другому. Незначительна  остаточна  деформаци , вызванна  перевивкой, уже н.е измен ет структуру материала, что обеспечивает сохранение его упругих и механических свойств. Получеипа  таким образом пружина может обладать чрезмерным предварительным напр жением , которое должно быть уменьшено до расчетного путем стабилизирующего отпуска при 400-500°С и соответствующего заневоливани , что также способствует упрочнению материала и улучшению упругих свойств пружины.

As a result, a pre-tensioned spring intertwined in reverse direction is obtained, the coils of which are tightly pressed against one another. Insignificant residual deformation caused by winding already does not change the structure of the material, which ensures the preservation of its elastic and mechanical properties. In this way, the spring may have excessive prestressing, which must be reduced to the calculated one by stabilizing tempering at 400-500 ° C and appropriate overvoltage, which also contributes to the strengthening of the material and the improvement of the elastic properties of the spring. The springs made in this way are used in a number of samples of domestic seismometers. Claims The method of manufacture of elastic, pre-stressed, helical springs for long-period seams: cm; meters by winding wire and heat treatment, characterized in that, in order to ensure the constant elastic properties of the spring and increase the stability of the tandem the springs are made in steps of 2-4 times the wire diameter, after which they are heated to 700-800 ° C and then cooled in air, then the spring is rewound for the second time. ..t, ..... „„ „j ,. The installation is carried out with a step equal to the wire diameter, and then the spring is subjected to stabilizing tempering at 400-500 ° C and its winding is performed.
