German Winkelmann springs Winkelmann models Winkelmann prices

Winkelmann springs are conical disc-shaped. They can be used individually or in series or parallel combinations. They withstand static or dynamic axial loads at the upper inner edge and lower outer edge. Upon compression, they deform until flattened, storing energy as a live load. When necessary, they automatically convert into additional compressive load required for sealing, reducing the continuous tightening requirements for gaskets and packing. Disc springs are special springs that are conical in the axial direction and bear loads. After deforming under load, they store potential energy. When bolts loosen, the disc spring releases part of the potential energy to maintain pressure in the flange connection to meet sealing requirements. The stress distribution of disc springs decreases uniformly from the inside out, achieving high compensation force with low travel.

Winkelmann spring structure

The torsion bar spring itself is a torsion bar made of spring steel. The cross-section of the torsion bar is usually circular, with a few being tubular or rectangular. Its ends can be shaped as splines, square, hexagonal, or cylindrical with flat surfaces, so that one end is fixed to the frame and the other end is fixed to the suspension arm, which is connected to the wheel.

Winkelmann spring features and functions

1) Wide stiffness range, strong buffering and vibration absorption capacity, and high deformation energy per unit volume of material. 2) Features variable stiffness characteristics. Stiffness can be corrected by changing the combination of wave peak height, width, and thickness. Stiffness can also be adjusted by varying the number of stacked discs. 3) Compared with disc springs, it offers advantages such as high strength, good flexibility, and strong impact resistance. 4) Compact structural dimensions; under the same theoretical parameters, it requires less installation space. Functions: (1) Control mechanical motion, such as valve springs in internal combustion engines and control springs in clutches. (2) Absorb vibration and impact energy, such as buffer springs under automobile and train carriages, and vibration-absorbing springs in couplings. (3) Store and output energy as power, such as clock springs and springs in firearms. (4) Used as force-measuring elements, such as springs in dynamometers and spring scales. The ratio of load to deformation of a spring is called spring stiffness; the greater the stiffness, the harder the spring. Springs are elastic elements widely used in the machinery and electronics industries. When loaded, springs undergo significant elastic deformation, converting mechanical work or kinetic energy into deformation energy. After unloading, the deformation disappears and the spring returns to its original state, converting deformation energy back into mechanical work or kinetic energy.

Winkelmann 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 buffering and vibration-damping springs. They serve as clamping springs for automobile 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 have several uniformly distributed slots cut radially from the standard disc spring; slots can be cut from the inner hole toward the outer diameter or from the outer diameter toward 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 disc spring assemblies, compound disc spring assemblies, and other combined disc spring assemblies. Compared with cylindrical helical springs, disc springs have the following characteristics: 1) The load-deformation characteristic curve is non-linear. 2) Disc springs are thin-walled, making them easy to form assemblies, allowing modular assembly and replacement, thus facilitating maintenance. 3) Disc springs with radial slots exhibit zero-stiffness characteristics. This feature can be applied in situations where the spring force is required to 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.
