We will give you advice in the matter of choosing the optimal material.
Spring calculation and ordering
When you calculate and order different types of springs and you do not know the drawing number of spring, you have to know the values below according to the particular type of spring.
Conical band springs - evolute:
| d - spring internal diameter | D - spring external diameter |
| spring |
F - spring load |
| spring |
Lo - spring free length |
| other values |
b - band thickness |
| h - band width | F1, ... - working load for height L1, |
| Fmax - maximum load for height Lmax |
Compression springs
| d - wire diameter | D - spring external diameter, eventually mean diameter | |
| Dm - spring external diameter, eventually mean diameter the spring needs to educe | Fn - maximum force | |
| other values |
Lo - spring free length | |
| Sn - maximum stroke |
Tension springs
| d - wire diameter | D - spring external diameter, eventually mean diameter | |
| Dm - spring external diameter, eventually mean diameter the spring needs to educe | Fn - maximum force | |
| other values |
Lo - spring free length | |
| Sn - maximum stroke |
