German tamawira springs tamawira models tamawira prices

tamawira springs are elastic elements with several 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 several peaks and valleys. This product uses high-quality spring steel 65Mn (60Si2MnA/50CrVA /0Cr17Ni7Al /SUS304), heat-treated using specific methods. Depending on the specific conditions, 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. With very small installation space, they offer special functions of noise reduction and vibration damping.

tamawira Spring Introduction

Designed based on the principle of moment balance. Within the permissible load displacement, the load moment and spring moment always remain in balance. For pipes and equipment supported by constant-load hangers, a constant support force can be provided during displacement, thus not imposing additional stress on the piping equipment. Constant-load hangers are generally used where displacement stress needs to be reduced, such as in the suspension parts of power plant boiler bodies, steam, water, flue gas, and air ducts of power plants, burners, as well as in the petroleum and chemical industries where such support is required. It is a mechanical part that works using elasticity. Parts made of elastic material deform under external force and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel. Springs come in complex and diverse types. Classified by shape, they mainly include helical springs, spiral springs, leaf springs, and special-shaped springs.

tamawira Spring Composition

Ring springs are a type of compression spring composed of several inner and outer rings with conical 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 diameters, the spring shortens in length; when the external force is removed, since the cone angle b of the rings is greater than the friction angle, the spring restores its original dimensions under the action of internal elastic forces. When ring springs bear axial P, significant friction is generated between the conical contact surfaces of the inner and outer rings, consuming a large amount of energy. At this time, the force and deformation still maintain a linear relationship. During the loading process, the external force P equals the sum of the spring's internal elastic force and friction force. ABO represents the unloading process, which includes two stages: the AB stage and the BO stage. The AB stage indicates the situation where the load decreases, and the spring's internal elastic 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 improve its load-bearing capacity, followed by heat treatment. Ring springs are heavy-duty springs with significant buffering and shock absorption capabilities (the ratio of area OABO to OACO can reach 60～70%). They are commonly used in buffering devices for heavy vehicles, artillery, and aircraft landing gear.

tamawira Spring Features

Suspensions using torsion bar springs have lighter mass, simpler structures, and do not require lubrication. By adjusting the installation angle of the fixed end of the torsion bar spring, automatic adjustment of vehicle body height is easily achieved. Torsion bar springs store greater elastic energy per unit volume and have low mass. Compared to helical springs, torsion bar springs are compact and easier to arrange. Torsion bar springs are widely used in off-road vehicles, light passenger cars, and trucks. According to their cross-sectional shape, torsion bar springs can be classified into circular, tubular, and strip types. Circular solid torsion bars have a simple structure and are the most commonly used. To assemble the torsion bar, its ends are machined into splines, hexagonal, square, etc. Since the spline head dimensions are relatively small, spline connections are mostly used. Generally, the major diameter of the spline is 1.2~1.3 times the working diameter of the torsion bar, and the spline length is approximately 1.4 times the spline major diameter. As long as the compressive stress on the spline teeth is within permissible limits, the spline teeth should not be selected too long. Torsion bar springs generally use involute splines GB3478. In the JSB2705 standard, the recommended standard pressure angle for splines is 45°; modules are 1mm and 0.75mm. To facilitate the assembly of torsion bar springs, some designs feature unequal diameters for the splines at both ends or machine a blind tooth on the spline teeth at both ends.
