Large High Compression Tension Coil Spring Nitinol For Garage Door

Heavy Duty Large Tension Compression Nitinol Spring Garage Door Extension Spring Tool

Tension spring is a spiral spring bearing axial tension, the hook in the form of side hook spring, long hook spring, English hook spring, German hook spring, semicircle hook spring, duck beak hook spring and so on," hook "is used to ensure the tension source of the stretching spring, generally made of circular section material spring steel, when not bearing load, The coil between the tension spring is generally tight without gap, and the use of stretch resilience (tension) work, to control the movement of parts, energy storage, measurement force, etc., most of the stretch spring is usually under a certain degree of tension, even in the absence of any load. This initial tension determines how tightly the stretch spring is wound without any load.

Design parameters
Indicate material diameter (D), outer diameter (d), total length (Ho), number of working rings (n), position and shape of earring, load (P 1 P 2...... P I) and corresponding values (H1H2...... Hj) as shown in Figure 2. If there is initial tension, add Po as shown in Figure 2.

Tension spring, suitable for high and low temperature, corrosion resistance and other working environment, materials mainly include stainless steel spring line, carbon steel wire, oil quenching and tempering alloy spring line, high and low temperature alloy spring wire.
