When we intend to design a spiral torsion spring, most of all, we need to know the application of the spiral torsion springs.
Compare with other’s flat coil springs, The spiral torsion springs mechanism feature obviously in the appearance, they own the almost same distance between each coil, which makes it zero friction and nearly linear counterbalance tortion when exerting rotation torque less than 360 degrees, once surpass 360 degrees rotation, the coils begin to be closed and the torque will burst in a short time.
This feature of almost linear torsion can be wildly used in many applications, like timers, brush motors, clocks, some toys, and so on.
YongSheng has been manufacturing springs for more than 18 years, has rich experience and a powerful R&D team makes us can easily handle all kinds of applications, customize it for you not just from the material, but also length, thickness, width, inner diameter, outer diameter.
With 18 sets of special forming machinery at hand, Yongsheng can produce 6,000,000 pcs flat wound springs every month. You will never feel anxious for springs stockout in the peak season.
in the below table, you can find several standard types of spiral torsion springs (standard tools and don’t need to open mold), choose your types, and you will get a good price.
if can’t find your ideal type, it doesn’t matter, please feel free to inquire about our expert to custom your idea products.
|Part Number||T(mm)||W(mm)||L(mm)||Min. Torque(N.mm)||Max. Torque(N.mm)||Turns||Arbor size(mm)||O.D(mm)|
T is thickness, W is width, L is length, O.D is the outer diameter. Normally, if you want us to produce a new style of spiral torsion spring, we need to know this information like thickness, width, O.D size, and Arbor size.
Meanwhile, if you want to design a new style of spiral torsion spring in your application, it’s better to tell the case size and shaft size besides the application, our engineer can assist you to design the CAD drawing based on this information.
