Factory Custom Brake Titanium Steel Return Tension Coil Spring With Dual Pull Hook
Tension spring characteristics
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.
The rings are tightly wrapped so that they can be stretched by force, and each end is wound in a Loop. The following is the necessary information for a stretch spring:
Parameters:
(1) free length :(a) total length, (b) total length of the loop, (c) length inside the hook loop.
(2) control diameters :(a) outer diameter, (b) inner diameter, (c) inner diameter of casing.
(3) Wire size "wire diameter".
(4) Materials (type, grade).
(5) number of turns :(a) total number of turns and (b) right or left.
(6) Terminal form.
(7) load in the hook.
(8) Load rate, deflection, pounds per inch.
(9) Maximum stretching length.
A typical example is the Extension Spring
