German reca springs, reca models, reca prices

reca springs are elastic elements with multiple peaks and valleys on a thin metal ring. They are typically used in applications with low loads and deformation, where low spring stiffness and axial preload are required. Wave springs are particularly suitable for weight-sensitive applications and those constrained by limited installation space. Typical application areas include aerospace, precision machinery, hydraulic seals, and high-end motors. They are thin, ring-shaped elastic metal components composed of multiple peaks and valleys. The product uses high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al /SUS304), is heat-treated using specific methods, and depending on the specific conditions, the hardness is generally controlled between HRC44 and 55. The surface is blackened, providing good elasticity. Wave springs are widely used in motors, textile machinery, hydraulic equipment, automotive, and other industries. They are mainly installed in bearing housings or bores suitable for their nominal dimensions. They require very little installation space and have special functions such as noise reduction and vibration damping.

reca Spring Classification

1) Based on the characteristics of the load during operation, helical springs can be divided into compression, extension, and torsion types; 2) Based on structural characteristics, they can be divided into two main categories: cylindrical helical springs and variable-diameter helical springs; variable-diameter helical springs mainly withstand compressive loads; 3) Based on shape characteristics, they can be divided into conical, volute, concave, and convex shapes. 4) In terms of production and use, helical springs can also be divided into large helical springs and small helical springs based on the forming method and material diameter; the former are usually hot-formed, while the latter are cold-formed. 5) Other classifications: There are many types of helical springs. By external shape, they can be divided into: ordinary cylindrical helical springs; variable-diameter helical springs. By the direction of the helix, they can be divided into: left-hand springs; right-hand springs. Variable-diameter helical springs are divided into: conical helical springs, volute helical springs, and concave helical springs. Cylindrical helical springs have a simple structure, are easy to manufacture, and are the most widely used. Their characteristic curve is linear, and they can serve as compression, extension, and torsion springs. When the load is high and radial dimensions are limited, two compression springs with different diameters can be nested together to form a combination spring.

reca Spring Classification

1) Torsion springs are springs that withstand torsional deformation, and their working part is also tightly wound into a helical shape. The end structure of a torsion spring is processed into various shapes of torque arms, rather than hooks. Torsion springs utilize the lever principle, twisting or rotating elastic materials with softness and high toughness to store significant mechanical energy. 2) Extension springs are helical springs that withstand axial tensile forces. When not under load, the coils of an extension spring are generally tightly closed with no gaps. 3) Compression springs are helical springs that withstand axial compressive forces. The cross-section of the material used is mostly circular, but rectangular and multi-strand steel wires are also used. The springs generally have equal pitch. The shapes of compression springs include: cylindrical, conical, convex, concave, and a small number of non-circular shapes. There is a certain gap between the coils of a compression spring. When subjected to external loads, the spring contracts and deforms, storing deformation energy. 4) Progressive springs: These springs adopt a design with inconsistent thickness and spacing. The advantage is that when the pressure is low, the part with a lower spring constant absorbs road undulations, ensuring ride comfort. When the pressure increases to a certain level, the thicker part of the spring supports the vehicle body. The disadvantage of this type of spring is that the handling feel is not direct, and the precision is poor. 5) Linear springs: The thickness and spacing of linear springs remain unchanged from top to bottom, and the spring constant is a fixed value. This design allows vehicles to achieve more stable and linear dynamic responses, facilitating better control for the driver. They are mostly used in performance-oriented modified cars and racing vehicles. The downside is that comfort is affected. 6) Short springs: Short springs are shorter and thicker than original factory springs. Installing short springs can effectively lower the vehicle's center of gravity, reduce body roll during cornering, make cornering more stable and smooth, and improve the vehicle's cornering handling. However, the damping setting of original factory shock absorbers leans towards comfort, so the combination of short springs and original factory shock absorbers is not very stable. They cannot effectively suppress the rebound and compression of short springs. When driving on bumpy roads, there will be an uncomfortable jumping sensation. Over time, the life of the shock absorbers will be greatly shortened, and oil leakage may occur. Of course, these situations are relative; daily driving will not cause such severe damage. Moreover, aggressive driving should be avoided, as original factory shock absorbers cannot withstand high-load pressure.

reca Spring Functions and Applications

1) Reset function: The spring deforms under external force and returns to its original state when the force is removed. Many tools and devices utilize this property of springs for resetting. For example, reset springs are installed on the hinges of many building doors, allowing the door to automatically return to its closed position after people pass through. This function is also used in products such as automatic umbrellas and mechanical pencils, offering great convenience. In addition, reset springs are essential components in various buttons and keys. 2) Drive function: Mechanical clocks and wind-up toys are driven by tightening the mainspring. When the mainspring is tightened, it undergoes bending deformation and stores a certain amount of elastic potential energy. Upon release, the elastic potential energy is converted into kinetic energy, driving rotation through the transmission mechanism. Toy guns, starting pistols, and military firearms also operate based on this property of springs. 3) Buffering function: Springs are installed between the frame and wheels of locomotives and automobiles, utilizing the elasticity of the springs to dampen vehicle vibration and shock. 4) Vibration and sound generation function: When air flows through the reed holes in harmonicas and accordions, it strikes the reeds, causing them to vibrate and produce sound.
