Helical disk springs

With our patented helical disk spring, we can offer our customers a proven and tested machine component which in many cases replaces the common multi-layer disc spring assembly. The helical disc spring consists of 2 identical flat wire compression springs screwed into one another to achieve a cross-section similar to that of disc springs. The uninterrupted grain structure of the raw material leads to an increased durability and reduces the risk of breakage of the coiled spring.

In principle, the characteristics of any inversely layered disc spring assembly can be

realized with a helical disc spring design. The load increase is proportional to the deflection since there appears only bending stress in the strip spring steel. It is also possible to apply a pitch during the coiling process of the helical disc spring, allowing it to initially display the characteristic of a compression spring and to work with the high loads of a disc spring assembly at the first contact of its coils.

The essential advantages at a glance:(基本优势一览)

1.【不错位】Single component design, avoiding mismatch and friction of individual discs;

单一组件设计, 避免了传统碟簧组中单片之间的错位偏移和摩擦力；

2.【力值稳定】No erroneous diagram results caused by incorrect layering or grease influence；避免因错误的叠加方式或涂油导致的力值曲线偏差；

3.【碎裂风险小】Uninterrupted grain structure reduce the risk of breakage;连续性结构避免了单片碎裂带来的风险，诸如力值变小、整组失效、碎片弹出等；

4.【弹性恒定】Stable spring loads even in case of breakage (no loss of deflection)；即使在弹簧碎裂的情况下（偏转无损伤），依然可以保持稳定的弹性负荷；而传统碟簧组在其中一片碎裂时，整组的性能将改变，并且会**导致其他单片逐一碎裂。

5.【无摩擦】No friction at mandrel or sleeve due to the fact that the stiffness of the spring allows to dispense with any guidance;整体结构允许免导杆运行，避免了传统碟簧组需要导杆或套筒固定而产生摩擦，**值；

6.【易安装】Simple and cost-saving assembly and maintenance；单体结构使得装配和维护更加简易、经济；

7.【专利定制】Tailor designed according to customer’s requirement；依据客户需求定制，用户授权制供货，杜绝**、伪造及任意经销；

8.【极限解决方案】High resistance to negative environmental conditions and extreme

With our patented helical disk spring, Roehrs can offer our customers a proven and tested machine component,which in many cases replaces the common multi-layer disc spring.assembly. The helical disc spring consists of two identical flat wire compression springs, screwed into one another to achieve a cross-section similar to that of disc springs. The uninterrupted grain structure of the raw material leads to an increased durability and reduces the risk of breakage of the coiled spring. 
Roehrs螺旋碟形弹簧是由采用ERCO 1812合金钢材制成的弹力面倾斜角度为β的--单头螺旋簧和弹力面倾斜角度为180°-β的第二单头螺旋簧相互嵌套叠合而成，所述的单头螺旋簧的断面呈半圆+矩形+半圆的两端圆滑的上下面平行的结构。该螺旋碟形弹簧具有体积小，载荷能力大和耐高温的特点，特别适用于大型钢包滑动水口机构，它安全可靠，经久耐用。其优点可归纳如下： 
• Lower unclamp force required 
• Custom-made to fi t a specifi c application 
• Reduced load on bearing 
• No “stacking” of belleville springs — a one-piece spring allows for much faster assembly 
• Low friction loss 
• Most spring force is maintained when springs break

螺旋碟簧-取代传统碟簧组，不错位、不易断裂、力值稳定 
Our patented helical disk spring is a tried and tested component which can often replace the familiar multi-layer disk spring assembly. It is made up of two identical helical compression springs screwed together, both made of steel strip with a cross-section similar to that of disk springs. The uninterrupted grain flow of the basic material increases service life and reduces the risk of fracture of the coiled helical disk spring. 
    Generally the function of any alternately layered column of disk springs is replaceable by a helical disk spring. The increase of force is proportional to the operating stroke, because bending stress only arises in the spring band steel. 
    The helical disk spring can even be coiled with winding distance, so it starts by operating with the characteristics of a helical pressure spring, but when it comes into contact with the windings it operates with the high spring force of a multi-layer disk spring. 
螺旋碟形弹簧又名双头螺旋碟簧，由两条完全相同的线圈弹簧相互绞旋而成，但每条线圈都被压成碟形弹簧片状。该弹簧-初适用于高速主轴拉刀机构，在替代传统碟簧组方面有着优越的表现，现在已经具备了可以替代任何碟形弹簧组的应用环境。它公开了有二级螺旋绕圈并绕，两圈的截面相对倾斜。它刚度高，摩擦小，结构紧凑，循环寿命长，避免了普通盘式碟形弹簧组工作时的错位、单片易损、力值不稳定的劣势。 

螺旋碟形弹簧的优点： 

1.和内外导杆摩擦损坏几乎为零 

2.拆装容易，不会有排列组合错误发生 

3.一条碟簧破裂，负荷仍不受影响 

4.多条绞合而成，能将扭力有效转化为扩张力 

5.能承受高速震动冲击，瞬间高负荷、高频负荷 

6.表面热塑化处理，寿命长，自我中心导引
