1, the characteristics of the
compression spring compression spring (
CompressionSprings)
Provide external load pressure resistance.
Compression spring is usually of wire pitch, such as coil and a fixed line size.
Compression spring with multiple open coil external pressure (
Such as gravity pressure wheel, or physical pressure on the mattress)
Supply resistance.
In other words, they pushed back against outside pressure.
In addition, there is also a conical compression spring, or cone and linear combination of the spring.
According to the different field of application of compression spring can be used to resist the pressure and (
Or)
Stored energy.
Round wire is the most commonly used compression spring, but also have a square, rectangle and special shaped wire producing compression spring.
2, the parameters of the compression spring
in the meaning of each representative for the above formula:
G = [shear elastic modulus
MPa,psi]
(
G value of size of steel 8000, stainless steel 7200)
d = [line diameter
mm,in]
effective laps [n =
-
]
D = diameter center [
mm,in]
k = [spring coefficient
N/mm,lb/in]
this formula is spring stiffness calculation formula of stiffness multiplied by the working stroke is equal to the efforts of spring.
according to the type, we can conclude that the parameters of the compression spring must be composed of: material, wire diameter, the diameter of center, the effective number of turns, the spring length, height of work, demand intensity of the parameters.
If the spring to strength without special requirement, can not provide the parameters of the spring working height and strength of demand
