40/4/4 spring Germany durovis model 40/4/4 price

40/4/4 springs are elastic elements with multiple peaks and valleys on a thin metal ring. They are typically used in applications where the load and deformation are small, requiring low spring stiffness and the application of axial preload. 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. This product uses high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al /SUS304), undergoes specific heat treatment, 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 industries such as motors, textile machinery, hydraulic equipment, and automotive. They are mainly installed in bearing housings or bores suitable for their nominal dimensions. They require very little installation space and have special functions of reducing noise and vibration.

40/4/4 spring surface treatment

1) Black oxide treatment: This surface treatment provides a black surface; black oxide is primarily for aesthetic improvement rather than corrosion resistance. 2) Chrome plating: Chrome plating is mainly used for carbon steel products, primarily to increase corrosion resistance. 3) Oil impregnation: Oil impregnation is the standard treatment for carbon steel products to prevent rust during transportation and storage. 4) Passivation: Passivation is a cleaning method for stainless steel materials. 5) Phosphate coating: Phosphating offers better corrosion resistance than black oxide. 6) Ultrasonic cleaning: This is the standard surface treatment for stainless steel materials. 7) Vibratory deburring: To remove sharp edges from the product.

40/4/4 spring features and functions

1) Wide stiffness range, strong buffering and vibration absorption capacity, and high strain energy per unit volume. 2) Variable stiffness characteristics. Stiffness can be adjusted by changing the combination of peak height, width, and thickness. Stiffness can also be adjusted by varying the number of stacked discs. 3) Compared to disc springs, they offer advantages such as high strength, good flexibility, and strong impact resistance. 4) Compact structural dimensions; under the same theoretical parameters, they require 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 car and train carriages, and vibration-absorbing springs in couplings. (3) Store and release energy as power, such as clock springs and springs in firearms. (4) Used as force-measuring elements, such as springs in force gauges and spring scales. The ratio of load to deformation in a spring is called spring stiffness; the higher the stiffness, the harder the spring. Springs are elastic elements widely used in the mechanical and electronic industries. When loaded, springs undergo significant elastic deformation, converting mechanical work or kinetic energy into strain energy. Upon unloading, the deformation disappears and the spring returns to its original state, converting strain energy back into mechanical work or kinetic energy.

40/4/4 spring functions and applications

1) Reset function: Springs deform under external force and return to their original state when the force is removed. Many tools and devices utilize this property for resetting. For example, reset springs are installed on the hinges of many building doors, allowing the door to automatically reset after people pass through. This function is also used in automatic umbrellas and mechanical pencils, offering great convenience. In addition, various buttons and keys require reset springs. 2) Drive function: Mechanical clocks and wind-up toys are driven by tightening the mainspring. When the mainspring is tightened, it bends and stores elastic potential energy. Upon release, the elastic potential energy converts to kinetic energy, driving rotation through a transmission mechanism. Toy guns, starter pistols, and military firearms also operate using this property of springs. 3) Buffering function: Springs are installed between the frame and wheels of locomotives and automobiles to use the spring's elasticity to reduce vehicle bumpiness. 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.
