Части ввинчены одна в другую и имеют ушки на торцах. Ушки у разных торцев противоположно отогнуты и жестко соединены. Перед вворачиванием пружины раст гивают и фиксируют в раст нутом положении, 2 с. и 1 з.п. ф-лы, 3 ил.Usage: mechanical engineering, for shock absorption and vibration isolation. SUMMARY OF THE INVENTION: A tension spring is made of pre-preloaded two parts. Parts are screwed into one another and have ears at the ends. The ears at different ends are oppositely bent and rigidly connected. Before screwing, the springs are stretched and fixed in the extended position, 2 s. and 1 z.p. f-ly, 3 ill.
Description
Изобретение относитс к машиностроению и может быть использовано дл амортизации , виброизол ции, создани начальных усилий и аккумулировани механической энергии.The invention relates to mechanical engineering and can be used for shock absorption, vibration isolation, creation of initial forces and accumulation of mechanical energy.
Известна пружина раст жени , содержаща собственно пружину с двум проушинами на концах.A tensile spring is known which comprises a spring with two eyelets at the ends.
Недостатком этой пружины вл етс пр ма зависимость упругости от толщины проволоки и качества стали, из которой она сделана, т.е. дл увеличени упругости приходитс увеличивать толщину проволоки, что влечет за собой увеличение габаритных размеров, веса и соответственно увеличение расхода металла.The disadvantage of this spring is the direct dependence of the elasticity on the thickness of the wire and the quality of the steel from which it is made, i.e. to increase the elasticity, it is necessary to increase the thickness of the wire, which entails an increase in overall dimensions, weight and, accordingly, an increase in metal consumption.
Известна пружина раст жени , имеюща ушки, котора прин та за прототип.A tensile spring having ears is known which is adopted as a prototype.
Недостатком такой пружины вл етс то, что при расширении диапазона воспринимаемых нагрузок она увеличивает свои габариты.The disadvantage of such a spring is that when expanding the range of perceived loads, it increases its size.
Известен также способ изготовлени A method of manufacturing is also known.
пружин раст жени ,.при котором проволокуtension springs, at which the wire
одновременно с навивкой закручивают относительно ее оси; этот способ прин т за прототип. simultaneously with the winding twist about its axis; this method is adopted as a prototype.
Недостатком этого способа вл етс то. что он дает незначительное увеличение упругости пружины.A disadvantage of this method is that. that it gives a slight increase in spring elasticity.
Целью изобретени вл етс расшире- ние диапазона воспринимаемых нагрузок при неизменном весе и габаритных размерах .The aim of the invention is to expand the range of perceived loads with constant weight and overall dimensions.
Указанна цель достигаетс тем. что пружина сделана из двух пружин раст жени , ввернутых соосно одна в другую, а проушины на концах ее спарены между собой.The indicated goal is achieved by that. that the spring is made of two extension springs screwed coaxially one into the other, and the eyes at its ends are paired with each other.
Эта цель достигаетс также способом изготовлени пружины; состо щим в том. что обе пружины, из которых она сделана, вначале раст гивают, удлин не менее чем в два раза, затем одну креп т снаружи на концы проволоки, а другую закрепл ют на вложенном в нее стержне и соосно друг другу вворачивают их одна в другую с последующим отгибанием проушин.This goal is also achieved by the method of manufacturing the spring; consisting in that. that both springs of which it is made are first stretched, the extension is at least two times, then one is attached externally to the ends of the wire, and the other is fixed on the rod inserted into it and screwed into each other coaxially with each other, followed by bending eyes.
На фиг.1 изображена предлагаема пружина , общий вид; фиг,2 и 3 иллюстрируют способ ее изготовлени .Figure 1 shows the proposed spring, General view; Figs. 2 and 3 illustrate a method for its manufacture.

Пружина раст жени выполнена из двух пружин 1 и 2, предварительно раст нутых и ввинченных одна в другую,-а также проушин 3, 4 и 5,6 отогнутых противоположно от каждой пружины и жестко соединен- ных друг с другом пайкой или сваркой 7.The tension spring is made of two springs 1 and 2, pre-tensioned and screwed one into the other, and also the eyes 3, 4 and 5.6 bent opposite from each spring and rigidly connected to each other by soldering or welding 7.
Способ изготовлени предлагаемой пружины включает раст жение пружин 1 и 2 на величину не менее чем в два раза с последующей фиксацией их в раст нутом положении (фиг.2 и 3).A method of manufacturing the proposed spring involves stretching the springs 1 and 2 by at least two times, followed by fixing them in the extended position (Figs. 2 and 3).
Пружину 1 креп т на концы на фиксирующем элементе снаружи (фиг,2), а пружину 2 - на стержне 8 вставленном внутри ее (фиг.З). Затем, одновременно враща стер- жень 8 с пружиной 2 и перемеща влево, ввинчивают пружину 2 соосно в пружину 1.The spring 1 is fastened to the ends on the fixing element from the outside (Fig. 2), and the spring 2 is mounted on the shaft 8 inserted inside it (Fig. 3). Then, simultaneously rotating the rod 8 with the spring 2 and moving to the left, screw the spring 2 coaxially into the spring 1.
Таким образом, предлагаема пружина раст жени получаетс предварительно напр женной с возможностью удлинени при рабочем ходе в два раза. Начальна сила упругости ее равна сумме упругостей двух пружин 1 и 2 напр женных при раст жении в два раза.Thus, the proposed tension spring is pre-stressed with the possibility of elongation during the working stroke by half. The initial elastic force is equal to the sum of the elasticities of the two springs 1 and 2, tensile under tension by a factor of two.
Опытный образец предлагаемой пружи- ны по сравнению с контрольной пружиной при одинаковых габаритах и весе показал увеличение упругости ее в 12 раз.A prototype of the proposed spring in comparison with the control spring with the same dimensions and weight showed an increase in its elasticity by 12 times.
