German kubo springs, kubo models, kubo prices

kubo 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 turn wraps tightly around the adjacent inner turn. When the metal strip is extended (twisted), internal stress resists the load force, similar to ordinary extension springs, 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, acting like a counterweight. Alternatively, the free end can be fixed while the spring itself provides the working force, similar to carbon brushes in electrical devices.

kubo spring applications

Compression coil springs are used in everything from home appliances to motorized equipment and motors, as they are the required spring type for these applications. Compressed by loads acting on them or their ends, compression springs are designed to return to their original shape, thereby pushing back against the load. Main application areas: medical respiratory equipment, mobile medical devices, hand tools, home care equipment, shock absorption, and engine valve springs.

kubo spring composition

Ring springs are a type of compression spring composed of several inner and outer rings with tapered surfaces. Under axial load P, significant normal pressure is generated between the contact surfaces of the inner and outer rings, causing the inner ring diameter to decrease and the outer ring diameter to increase. Due to these changes in diameter, the spring shortens in length; when the external force is removed, the spring restores its original dimensions under elastic internal forces, since the taper angle b of the rings is greater than the friction angle. When ring springs bear axial P, significant friction is generated between the tapered contact surfaces of the inner and outer rings, dissipating considerable energy, while the relationship between force and deformation remains linear. During loading, the external force P equals the sum of the spring's internal elastic force and friction. ABO represents the unloading process, which includes two stages: the AB segment and the BO segment. The AB segment indicates the situation where the load decreases, and the spring's elastic internal force overcomes static friction, gradually restoring the spring to its original state. The inner and outer rings of ring springs are made of high-quality carbon steel or wear-resistant alloy steel. Each ring is first roll-formed to the required shape to enhance its load-bearing capacity, followed by heat treatment. Ring springs are heavy-duty springs with substantial buffering and shock-absorbing capabilities (the ratio of area OABO to OACO can reach 60～70%), commonly used in buffering devices for heavy vehicles, artillery, and aircraft landing gear.

kubo spring classification

1) Standard disc springs, trapezoidal cross-section disc springs, conical trapezoidal cross-section. Disc springs: Simple shape and structure, widely applied. They can be used individually, in opposed pairs, stacked combinations, or composite disc spring groups, bearing static or variable loads. Used as heavy-duty buffering and vibration-damping springs in heavy machinery, aircraft, cannons, and other weaponry. 2) Diaphragm springs: Primarily used in automotive clutches, functioning through both separation fingers and disc spring action. 3) Wave washers: Extensively used in mechanical seals; can further develop into spiral wave springs. 4) Slotted disc springs: Typically used in clutches, such as those in lathes, automobiles, and tractors. 5) Circular plate disc springs: Feature a circular plate cross-section, deforming into a truncated cone shape under load. Simple structure with high stiffness, used for applications with special requirements. 6) Spiral disc springs: Possess dual characteristics of disc springs and coil springs, allowing for varying stiffness requirements. 7) Wave cylindrical springs (wave springs): Formed by stacking wave washers into a cylindrical shape, achieving larger deformations.
