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 is allowed the spring may bind on the mandrel and break/deform.

– The size of the hole within which the spring operates. The outside diameter of a torsion spring expands during deflection as more wire feeds into the body of the spring during deflection; therefore, if there is insufficient space, the spring may bind within the space and break/deform.

– The lateral space available. As a torsion spring deflects, it increases in length and may fail if this growth cannot be accommodated in the application.

– The torques/forces and rotation required.

– The intended environment. This will affect the suitable material and and finish requirement (i.e. for corrosion protection).

– The maximum working deflection required.

– The frequency of operation.

– How and where the spring fits. This will determine type of ends required.
