Product Description

65mn Spring Steel Switch Conical Spring, Compression Coil Spring Automobile;auto;car


Product Description


d (spring wire diameter) : This parameter describes the diameter of the spring wire.
s (Maximum mandrel diameter) This parameter describes the maximum diameter of a spring shaft in industrial applications.
De (outsole diameter) : outside diameter of the widest end of the spring.
De (small bottom outside diameter) : outside diameter of the narrowest end of the spring.
H (minimum aperture): This is the diameter of the minimum space required for the spring to function properly.
Lc (compression length) : the theoretical length when the spring is pressed to the contact of each coil. For most tower springs, this value is equal to two parts of the wire diameter.
L0 (natural length): the length of the spring in its natural state after being pressed and passed once.
R Spring stiffness: This parameter represents the change in load of a spring per unit of deformation. Unit calculation: 1 DaN/mm = 10 N/mm (Newton /mm), tolerance ±15%.
L1 & F1 (length of spring under the action of load F1 L1) : load F1 and length L1 can be calculated by this formula: F1 = (L0-L1)* R, and then calculate the length L1: L1 = L0-F1 /R
