Compression Spring Technical Parameters Introduced
Compression spring are widely used computer, electron, home appliances, camera, instrument, motorcycle, automobile, railway, electric power station, engineering machinery, mining machinery, construction machinery, elevator and other industry.
Compression spring technical parameters:
D (wire diameter): the diameter of wire used as material for spring.
S (shaft): the maximum diameter of spring shaft in industrial applications.
Di (internal diameter): Internal diameter of a spring can be calculated by subtracting the doubled wire diameter from the external diameter of a spring.
De (external diameter): External diameter of a spring can be calculated by adding the doubled wire diameter to the internal diameter of a spring.
H (hole): This is the minimum diameter of the hole in which spring can work.
P (pitch): Average distance between two subsequent active coils of a spring.
Ln (block length): Maximal length of a spring after total blocking. This parameter is shown in the picture on right.
L0 (free length): Free length of compression springs is measured in its uncompressed state after previous one time blocking.
Nr of coils: This is a total number of coils in a spring - in the picture above it is equal to six. To calculate number of active coils subtracts two terminating coils from total number of coils.
R (spring rate): This parameter determines spring's resistance, while it is working. It is measured in 1 Dan/mm = 10 N/mm.
L1 & F1 (length at force F): Force F1 at length L1 can be calculated from equation: F1 = (L0-L1)
