German voss federn springs, voss federn models, voss federn prices

voss federn springs are mechanical energy storage structures, primarily used in ancient ballistae and other crossbow-type weapons. Torsion springs store energy by twisting or rotating elastic materials that are soft and highly tough, thereby imparting a certain amount of mechanical energy to the projectile. Modern torsion spring torque bars are mostly made of steel with good elasticity, and their forms have varied greatly; examples include the hairsprings in mechanical watches, power springs in toy gyro guns, and torque bars in tanks and automobiles. Torque bars are compact yet provide high torque, making them ideal as shock absorption components for transportation vehicles.

voss federn spring mechanical principles

Ring springs consist of outer rings with inner conical surfaces mating with inner rings with outer conical surfaces. The number of ring pairs is determined by the magnitude of the load and deformation requirements. Ring springs are commonly used in applications where space is limited but strong buffering is required. A ring spring comprises many pairs of inner and outer rings; if damaged or worn, it is not necessary to replace the entire assembly, only the individual discarded rings need to be replaced, making repair easier and more economical. Due to the significant friction on the contact surfaces when the outer and inner rings slide relative to each other along the mating cones, the axial force during loading is balanced by surface pressure and friction. This effectively reduces the effect of the axial load, i.e., increases the spring stiffness. During unloading, friction hinders the recovery of the spring's elastic deformation, thus effectively reducing the spring force. The characteristic curve of a ring spring during one loading and unloading cycle is OABO; without the effect of friction, it would be OC. During unloading, the characteristic curve switches from point B, rather than from point E, due to the reduction caused by spring elastic hysteresis. Ring spring: A spring composed of alternating stacked washer-like spring steel rings with inner conical and outer cylindrical surfaces, and washer-like spring steel rings with inner cylindrical and outer conical surfaces. The number of inner and outer ring pairs in a ring spring is determined by the magnitude of the load it bears and the deformation requirements.

voss federn spring structural classification

Based on the nature of the force, springs can be classified into tension springs, compression springs, torsion springs, and bending springs. Based on shape, they can be classified into disc springs, ring springs, leaf springs, helical springs, truncated cone volute springs, and torsion bar springs. Based on the manufacturing process, they can be classified into cold-coiled springs and hot-coiled springs. Ordinary cylindrical springs are the most widely used due to their simple manufacturing, ability to be formed into various types according to load conditions, and simple structure. Spring manufacturing materials should generally possess high elastic limits, fatigue limits, impact toughness, and good heat treatment performance. Commonly used materials include carbon spring steel, alloy spring steel, stainless spring steel, as well as copper alloys, nickel alloys, and rubber. Spring manufacturing methods include cold coiling and hot coiling. Spring wire diameters less than 8 mm are generally cold-coiled, while those greater than 8 mm are hot-coiled. Some springs undergo strong pressing or shot peening treatment after manufacturing to improve their load-bearing capacity.

1) Ordinary disc springs, trapezoidal cross-section disc springs, conical trapezoidal cross-section. Disc springs: Simple in shape and structure, widely applied. They can be used individually, in opposed pairs, in stacked combinations, or as composite disc spring groups, bearing static or variable loads. They are used as heavy-duty buffering and vibration-damping springs in heavy machinery, aircraft, artillery, and other weapons. 2) Diaphragm springs: Primarily used in automotive clutches, functioning through the separation fingers and the disc spring part. 3) Wave washers: Extensively used in mechanical seals, further developable 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: With a circular plate cross-section, deforming into a truncated cone shape under load. Simple in structure with high stiffness, used in applications with special requirements. 6) Spiral disc springs: Possessing dual characteristics of disc springs and helical springs, allowing for different stiffness requirements. 7) Wave cylindrical springs (wave springs): Formed by overlapping wave washers into a cylindrical shape, allowing for greater deformation.
