schroeder federn spring is a special type of extension spring, suitable for applications with large elongation and non-increasing load. Constant-force springs consist of spiral metal strips; the inner side of the strip is curved so that each turn wraps tightly around the inner turn. When the metal strip is stretched (twisted), internal stress resists the load force, just like a standard extension spring, but the spring rate is 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, acting like a counterweight. Alternatively, the free end can be fixed, allowing the spring itself to provide the working force, similar to carbon brushes in electrical devices.

Introduction to schroeder federn springs

Designed based on the principle of torque balance. Within the permissible load displacement, the load torque and spring torque remain balanced. For pipes and equipment supported by constant hangers, a constant supporting force is provided during displacement, thereby avoiding additional stress on the piping and equipment. Constant hangers are generally used where displacement stress needs to be reduced, such as in the suspension parts of power plant boiler bodies, steam, water, flue gas, and air ducts in power plants, burners, and similar support requirements in the petroleum and chemical industries. It is a mechanical component that works using elasticity. Components made of elastic material deform under external force and return to their original shape after the force is removed. Also known as "spring". Generally made from spring steel. Springs come in complex and diverse types; classified by shape, they mainly include helical springs, volute springs, leaf springs, and special-shaped springs.

schroeder federn spring materials

Disc springs are mostly manufactured from cold-rolled or hot-rolled strip steel, plate steel, or forged blanks (forging ratio not less than 3). The materials commonly used are spring steels such as 60S2MA and 50CVA. For thicknesses less than 1.1, high-carbon steel can also be used. Performance requirements for disc spring materials include high ultimate strength, yield limit, elastic limit, and fatigue limit after heat treatment, along with high impact toughness, plasticity, and a high yield-to-tensile strength ratio. To meet these performance criteria, high-quality cold-rolled or hot-rolled steel strips or plates are widely used domestically and internationally. For disc springs with thickness greater than 6 mm, forged blanks are used, primarily consisting of medium-carbon low-alloy spring steels (silicon-manganese or chromium-vanadium spring steels) and high-quality carbon spring steels. Due to the high silicon-manganese content and low chromium-vanadium availability in China, disc springs mainly use 60Si2MnA. Comparing the two, 50CrVA has better hardenability, temper stability, and impact toughness than 60Si2MnA, but 50CrVA is more expensive and suitable for applications with high fatigue requirements.

schroeder federn spring applications

Disc springs are replacing cylindrical helical springs in a wide range of applications. They are commonly used in heavy machinery (such as presses) and weapons like artillery and aircraft as high-force buffer and vibration-damping springs, as clamping springs for automotive and tractor clutches and safety valves, and as energy storage elements in mobile mechanisms. Disadvantage: Load deviation is difficult to guarantee. Disc springs can be divided into three categories based on cross-sectional shape: standard disc springs (rectangular cross-section), disc springs with radial slots, and trapezoidal cross-section disc springs. Standard disc springs are divided into those with support surfaces and those without. Disc springs with radial slots are derived from standard disc springs by cutting several uniformly distributed slots radially; these slots can extend from the inner hole to the outer circumference or from the outer circumference to the inner hole. Trapezoidal cross-section disc springs are divided into two types: those with inner edge thickness greater than outer edge thickness, and those with inner edge thickness less than outer edge thickness. Since the deformation and load values of a single disc spring often fail to meet usage requirements, they can be used in groups to form disc spring assemblies (columns). Typical combinations include: stacked combination disc springs, compound combination disc springs, and other combined disc springs. Compared to cylindrical helical springs, disc springs have the following characteristics: 1) The load-deflection characteristic curve is nonlinear. 2) Disc springs are thin and easy to form into assemblies, allowing modular assembly and replacement, which facilitates maintenance. 3) Disc springs with radial slots exhibit zero stiffness characteristics. This feature is applicable in situations where the spring force must remain basically stable within a certain deformation range. 4) The vibration absorption performance of disc springs is no lower than that of cylindrical helical springs; when using stacked combinations, friction between disc spring sheets provides significant damping, dissipating impact energy.
