Description

Иорцибиальна пластичности участка ui Этот моиент способствует уменьшению наружного диаметра спирали.Iorcibial plasticity of the ui region. This myent helps to reduce the outer diameter of the helix.

Таким образом, дейстйие хрут цего момента И} позвол ет при неизменной геометрии пели, а поэтому при меньших степен х деформации заготовки, получить шнеки с более толстой наружной кромкой .S и меньшим наружный диаметром , а также нспол зовать в качестве заготовки менее пластичные материалы .Thus, the action of the torque of the moment I} allows, with a constant geometry, sang, and therefore with lower degrees of deformation of the workpiece, to obtain screws with a thicker outer edge .S and a smaller outer diameter, and also to use less ductile materials as a blank.

Общий экономический эффект от использовани  изобретени  составит около 300 тыс.руб.The total economic effect from the use of the invention will be about 300 thousand rubles.
