German hail tec springs, hail tec models, hail tec prices

hail tec springs are mechanical energy storage structures, primarily used in ancient ballistae and other crossbow types. 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. Their forms have varied greatly, including 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.

hail tec spring installation and removal

Hydraulic hand pallet trucks are widely used in production. During maintenance of their pressure oil pumps, we found that the pressure spring responsible for returning the piston rod of the pressure oil pump and the pressure arm of the truck has a wire diameter of n and stores elastic force up to 1000N, making its installation and removal very difficult. This often delays troubleshooting and directly affects production progress. Several measures were taken, but none were effective. Therefore, I designed a pressure spring installation/removal tool as shown in Figure 1. The tool consists of a lower pressure lever 1, pressure blocks 10, connecting pins 14, nuts 1, spherical washers 12, upper pressure lever 13, positioning sleeves 16, and levers. During operation, rotate the nut 11 to an appropriate position so that the cylindrical head claw of the lower pressure lever 1 contacts the vehicle body 2. The two pressure blocks 10 press symmetrically on the washer 6. Rotate the pressure nut n to tighten the pull rod 15, causing the upper pressure lever 13 and lower pressure lever 1 to move relative to each other, forcing the pressure spring to compress. When the washer 6 separates from the cylindrical pin 7, the pressure wheel axle 9, pressure wheel 8, and cylindrical pin 7 can be removed. Then, loosen the nut 11, remove the installation/removal tool, and take out the pressure spring to disassemble, inspect, and repair the pressure oil pump. The positioning sleeve 16 on the installation/removal tool is a key component. During manufacturing, one end features an internal spherical surface with a slot-shaped hole in the middle, and the other end is a slanted flat surface. It fits with the pressure lever via an interference fit. It must make good contact with the spherical washer 12 and the ball head of the lever 15. The pressure block 10 and connecting pin 14 have a clearance fit, requiring flexible rotation. The connecting pin 14 and upper pressure lever 13 have an interference fit. The connecting shaft 18 and pressure lever have a clearance fit.

hail tec spring classification

1) Torsion springs: Torsion springs (torsional springs) utilize the principle of leverage. By twisting or rotating elastic materials that are soft and highly tough, they store significant mechanical energy. These springs withstand torsional deformation, and their working parts consist of coils that are either closely wound or spaced apart. The ends of torsion springs are processed into various shapes of torsional arms, ranging from single torsion to double torsion, and even various torque bar deformations, depending on the design. Torsion springs are commonly used in balancing mechanisms in machinery and are widely applied in industrial production such as automobiles, machine tools, and electrical appliances. 2) Compression springs: Compression springs are helical springs that withstand axial pressure. Springs are generally classified into constant-pitch and variable-pitch types. Shapes of compression springs include cylindrical, conical, convex, concave, and a small number of non-circular forms. 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. Variable-pitch springs are becoming increasingly common, not just constant-pitch springs. Variable-pitch springs can perform different functions in different environments. 3) Carbon nanotube springs: The diameter of carbon nanotube springs can reach hundreds of micrometers, while their length can reach several centimeters. Their spun structure has broad application prospects, potentially applicable in stretchable conductors, flexible electrodes, micro strain sensors, supercapacitors, integrated circuits, solar cells, field emission sources, and energy dissipation fibers. This provides the possibility of preparing carbon nanotube electronic devices visible to the naked eye. They are also expected to be used in medical devices, such as tension-sensing bandages. This new structure can also be developed into multifunctional carbon nanotube fiber composites for utilization. 4) Extension springs: Extension springs are helical springs that withstand axial tensile forces. Extension springs are generally made from round cross-section materials. When not under load, the coils of extension springs are usually tightly closed with no gap. They work using the restoring force (tensile force) after extension, used to control component movement, store energy, measure force magnitude, etc., and are widely used in machines and instruments. Hook forms include side-hook extension springs, long-hook extension springs, British-hook extension springs, German-hook extension springs, semi-circular hook extension springs, duck-bill hook extension springs, etc. Materials include stainless steel, music wire, high-carbon steel, phosphor bronze, beryllium copper, and oil-tempered alloy spring steel. 5) Air springs: Air springs are non-metallic springs that achieve elastic action by adding pressurized air into a flexible sealed container, utilizing the compressibility of air. They can be roughly divided into bladder type and diaphragm type. Air springs have excellent elastic characteristics. Using them in suspension systems of high-end vehicles can greatly improve vehicle ride smoothness, thereby significantly enhancing driving comfort. Therefore, air springs are widely used in automobiles and railway locomotives. In addition, since air springs have many advantages compared to ordinary steel springs, they are also applied in some mechanical equipment and precision instruments.

hail tec spring features

Suspension systems using torque bar springs are lighter in weight, have a simpler structure, and do not require lubrication. By adjusting the installation angle of the fixed end of the torque bar spring, automatic adjustment of vehicle height is easily achieved. Torque bar springs store greater elastic energy per unit volume and have low mass. Compared to helical springs, torque bar springs are compact and easier to arrange. Torque bar springs are more commonly used in off-road vehicles, light passenger cars, and trucks. Torque bar springs can be classified by cross-sectional shape into circular, tubular, and leaf types. Circular solid torque bars have a simple structure and are the most commonly used. To assemble the torque bar, its ends are processed 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 to 1.3 times the working diameter of the torque bar, and the spline length is approximately 1.4 times the major diameter of the spline. As long as the crushing stress of the spline teeth is within permissible limits, the spline teeth should not be selected too long. Torque 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 torque bar springs, some torque bar springs have unequal diameters at both ends of the splines, or a blind tooth is machined on the spline teeth at both ends.
