Constant force spring usually installed with one end wrapped tightly on the drum and the other end connected to the load. We should know below knowledge during the installment procedure.
- The drum diameter should be 10% to 20% larger than its natural diameter.
- One and one-half length of the spring should bewrapped on the drum.
- Stainless steel strip springs become unstable when stretched for a long time and should be guided to prevent twisting or kinks during recoil.
- The diameter of the drum must be greater than the natural diameter and must never be used to contribute to a backbend opposite the natural radius of curvature.
- Constant force springs can be installed in the cavity without bushings.This installation means is simple and cheap. However, the friction encountered results in relatively high lag.
- Constant force springs mounted back to backcan make the sum of the two spring forces available at one point. This approach also provides stable extension over long deflections.
- Mounting in series also makes the sum of the two spring forces available at one point, but does not increase stability.
- Pulley mounting doubles the force of a single constant force spring, but reduces cycle life.Laminated installation, where two or more springs are intertwined into an assembly, providing the sum of their forces in the smallest possible space.
