德國SEFKO雙螺旋彈簧，術(shù)業(yè)名詞Helical disc spring，由兩個相同的扁線壓縮彈簧組成,通過螺旋相互擰緊，來實現(xiàn)與盤式碟簧組相似的截面。連續(xù)的扁線結(jié)構(gòu)避免了沖壓件造成的分子結(jié)構(gòu)破壞，從而增強了組件的耐用性，同時降低了盤式彈簧片錯位、破碎帶來的風(fēng)險。負(fù)荷的增加與螺旋彈簧鋼的彎曲應(yīng)力成正比。我們同樣可以在卷曲過程中實現(xiàn)螺旋碟簧的傾斜纏繞，來展示壓縮彈簧的特點，同時達(dá)到盤式碟簧組的高負(fù)荷特點。
相比普通的碟形彈簧組合，SeFko雙螺旋彈簧基本優(yōu)勢一覽:
•單一組件設(shè)計,沒有拆分為單獨的片狀,避免了傳統(tǒng)碟簧組使用過程中錯位的現(xiàn)象；
•裝配和維護(hù)更加易操作、低成本；
•用小的外徑達(dá)到超高的彈簧負(fù)載，彈性磁滯低；
•避免因錯誤的疊加方式或涂油導(dǎo)致的力值錯誤；
•連續(xù)鋼帶結(jié)構(gòu)使性能更持久；
•較高的操作安全性，
•可根據(jù)客戶要求設(shè)計彈簧性能；
•可避免彈簧與導(dǎo)桿或套筒之間的摩擦，允許免導(dǎo)桿運行；
•可適應(yīng)極端的的工作環(huán)境和溫度變化；
•靈活而經(jīng)濟的生產(chǎn)能力可接受任何數(shù)量的訂購；

German SEFKO double coil spring, the professional term Helical disc spring, consists of two identical flat line compression springs by screw tightening to achieve a similar section to the coil set. Continuous flat line structure avoids the molecular structural damage caused by the stamping parts, thus enhancing the durability of the component, while reducing the risk of dislocation and fragmentation of the disc spring plates. The increase in load is proportional to the bending stress of the spiral spring steel. We can also realize the tilt winding of the coil disc spring, to show the characteristics of the compression spring, while achieving the high load characteristics of the disc spring group.
Compared with the ordinary disc spring combination, SeFko double spiral spring basic advantages:
A single component design, not divided into separate pieces, to avoid the phenomenon of dislocation in the use of the traditional disc group;
Assembly and maintenance are easier to operate and at low cost;
With a small outer diameter to achieve an ultra-high spring load, low elastic hysteresis;
Avoid the wrong force value due to the wrong stacking mode or oil coating;
Continuous steel strip structure makes a more lasting performance;
High operational security,
Spring performance can be designed according to customer requirements;
Avoid friction between spring and guide rod or sleeve and allow guide rod operation;
Adapt to the extreme working environment and temperature changes;
Flexible and economical production capacity accepts any number of orders;
Specification & Category:
All the specifications of German SEFKO double spiral spring are fixed products (customized), and the specifications in the market are carefully designed products of each brand. To protect the interests of the spindle manufacturer, all the new designed products, we will treat the specifications confidential. Ensure that the service sales of the spindle manufacturers are effectively guaranteed.
Extensive used:
SEFKO double spiral spring in Germany is mainly used in the main axis of the core parts of machine tools. At present, this product has been commonly used in the high-speed spindle in Europe and the United States. In addition, steel mills, brake systems, valves, oil rigs and nuclear power.
