Description

Custom heavy duty large clutch compression coil spring with closed end

Description

Compression spring is under axial pressure of the spiral spring, can withstand the pressure, both ends can be open or closed or round flat or smooth, materials used in the cross section is round more, it is also useful for rectangular and multi-strand steel rolled a travelling.

springs have a pitch and defect, such as the shape of the compression spring are: cylindrical, conical, convex and concave, and a small amount of noncircular and the variation of various end, All products need to be shaped in accordance with the design, etc.

Compression spring is a kind of metal accessories formed by the line spiral geometry, so the hardening and strengthening of his operation is more difficult than the plane hardware accessories (such as stamping parts), in addition to strictly control the hardening effect of the cross section of the pressure spring, so as to fully decompression spring after the use of fatigue fracture resistance.

F=kx, where F is the spring force, k is the stiffness coefficient, and x is the elongated length of the spring
For example, to test a 5N spring:
With 5N force pull stiffness coefficient of 100N/m of the spring, the spring is elongated by 5cm
F=kx,k is stiffness coefficient (in newtons per meter), x is spring elongation (in meters), this law is called Hooke's law

Characteristics of compression spring
Compression springs are generally coils of wire equal pitch and have a fixed wire diameter. Compression springs use multiple open coils to provide resistance to external pressure (such as gravity pushing down a wheel or the body pressing down on a mattress). Compression springs are generally coils of wire equal pitch and have a fixed wire diameter. In addition, there are conical compression springs, or a combination of conical and linear springs. Depending on the application, compression springs can be used to resist pressure and/or store energy. Round wires are the most commonly used compression springs, but there are also various springs made of square, rectangular, and special-shaped wires.
