Tension Springs: A Comprehensive Guide

Tension springs, also known as extension springs, are vital components in various mechanical systems. They are designed to absorb and store energy while providing resistance to pulling forces. This guide will delve into the technical features, types, and applications of tension springs, highlighting their importance in industries ranging from automotive to aerospace.

Understanding Tension Springs

Tension springs are helical springs that bear axial tension. They are typically made from spring steel and are characterized by their tightly coiled structure when not under load. The initial tension in these springs is crucial, as it determines how tightly the coils are wound without any load. This feature allows them to maintain a certain degree of tension even when not in use.

Technical Features of Tension Springs

The following table summarizes the key technical features of tension springs:

Feature	Description
Material	Commonly made from stainless steel, carbon steel, and alloy steel.
Wire Diameter	Ranges from 0.05 mm to 65 mm, depending on the application.
Finish	Options include zinc plating, chrome plating, and powder coating.
Processing	Involves coiling, heat treatment, and surface treatment for durability.
Applications	Used in automotive, aerospace, electronics, and machinery.
Quality Certification	ISO9001:2000, ISO14001, SGS certifications ensure quality standards.

Types of Tension Springs

Tension springs come in various types, each designed for specific applications. The following table outlines the different types of tension springs and their characteristics:

Type	Description
Standard Tension Springs	Basic helical springs used in general applications.
Long Hook Tension Springs	Feature extended hooks for specific mounting requirements.
Double Hook Tension Springs	Have hooks on both ends for balanced tension distribution.
Trampoline Springs	Designed for high elasticity and strength, used in trampolines.
