OEM Stainless Steel Constant Force Clockwork Spring

The constant force spring is made of stainless steel strip, and the high-strength steel strip is shaped by special production spring equipment. When the external force straightens it, the spring will naturally roll back and generate elastic force. However, to achieve our goal is to move. After that, we can return to the starting point we specified.

The constant force spring has the characteristics of maintaining constant force in a long stroke, and can be applied to products that require linear movements such as reciprocating, sliding, stretching, homing, balancing or labor saving. Like we go to common fan lifts, store display shelves, tape measures, sliding doors and windows and computer monitor lifts, etc. Then if you choose a constant force spring that suits your product, there are 8 steps in the design.

1. Select Material – Most of the flat steel springs produced by Pintejin are made of type 301 stainless steel. This material is the most accessible and predictable. Pintejin engineers can assist in selecting standard sizes to expedite the process.
2. Estimate the life cycle – The life of a constant force spring is very predictable, making it one of the most important considerations. Being realistic is important because longer life cycles are estimated to result in larger, more expensive designs. Underestimating the life cycle of constant force springs can lead to premature failure. Common lifetimes range from 4,000 to about 25,000 lifetimes. If a longer life cycle is required, increased spring diameter and force tolerances due to low stress levels and small differences in materials must be considered.
3. Build-up force – The force of the constant force spring should be equal to the requirements of the application. The standard tolerance for constant spring force is ±10%.
4. Determine the space——. The inner diameter (ID) of the spring depends on the thickness, life cycle and required force. The outer diameter (OD) depends on the above, with the overall length as an additional consideration. The constant force spring does not extend tangentially to the spring body. Standard tolerance for ID and OD is ± 10%.
5. Calculate Overall Length – The overall length of the spring should take into account the actual elongation of the spring in the application, plus at least enough material to hold 1-1/2 turns on the spring at full extension.
6. Select End Details – Pintejin has many standard end details available. Pintejin Precision is equipped with a complete tool and die department capable of creating many custom designs required by customers.
7. Consider the environment – corrosive atmospheres or extreme temperatures can affect spring life and material selection.
8. Complete the design – Once all the above criteria are considered the spring can be located or deduced.
