Common Mistakes in Torsion Spring Design – Video

Our brand-new Springtelligence video looks at the common mistakes made when designing a torsion spring. The four main spring design flaws which we look at and demonstrate in this video are: - Incorrect direction of operation - Inside diameter too small - Body length too large - Overstressing It is also important to consider: - The size of the mandrel over which the spring operates. The inside diameter of a torsion spring reduces during deflection; therefore, if insufficient space [...]

Torsion spring design common pitfalls

What is a torsion spring? A torsion spring is a tightly coiled helical spring which stores and releases energy to resist force applied through torque. Nothing lasts forever. However, JB Springs' compression, torsion and tension springs are designed with a view to them having a very long lifespan – potentially outlasting other components within their application. The following factors can cause failure in compression springs and tension springs as well as torsion springs, however, this blog will focus on [...]

Prestressing: Ensuring high spring quality

Prestressing is a quality-improving process often implemented during the manufacture of springs – mainly compression springs – to enhance their mechanical properties and improve their fatigue life (life cycle). The process involves compression by loading a spring past its elastic limit until it reaches a solid position or a predetermined length (the latter is less common) and plastic deformation occurs. This results in a number of enhancements to the spring including: Increased elastic deformation Increased load capability Improved relaxation [...]

How Fit and Function Affect Spring Longevity

It is fundamental to optimal spring operation and spring longevity that it fits and works freely within the space available. While this may sound obvious, insufficient space for a spring to operate within is a common cause of spring failure. How Fit and Function of Compression Springs Affects Spring Longevity Compression springs often fit over a rod, within a bore, or sometimes both. It is imperative that the spring does not rub on either of these. This will prevent [...]
