scherdel spring is a special type of extension spring, suitable for applications with large elongation and constant load. Constant-force springs consist of spiral metal strips; the inner side of the strip is curved so that each coil wraps tightly around the inner coil. When the metal strip is stretched (twisted), internal stress resists the load force, just like a standard extension spring, but the spring rate remains nearly constant (zero). See the load/torsion diagram. In use, an ID is typically used to wind this spring tightly onto a drum, with its free end connected to the load.
scherdel fasteners Germany scherdel models scherdel prices
scherdel fasteners feature internal threaded holes and are generally shaped as flat hexagonal prisms, though flat square prisms or flat cylindrical shapes are also available. They are used in conjunction with bolts, studs, or machine screws to securely connect two parts into a single assembly. Nuts operate by using the friction between the nut and bolt for self-locking. However, the reliability of this self-locking decreases under dynamic loads. In critical applications, anti-loosening measures are taken to ensure the reliability of the nut locking. As an essential component for all manufacturing machinery, depending on the material,
