Torsion Springs

Central Springs and Pressing Limited has been a trading body for the past 14 years, although the origins venture much further back to the 18 th century. Central Springs was developed from the original company Herbert Terry & Sons Ltd (Terrys), which was established in 1855.

Torsion springs are a specialised type of spring designed primarily for rotary applications. Their unique design allows them to store and release energy by twisting, providing torque or rotational force when subjected to an external load. Torsion springs have a wide range of applications, from small and delicate devices to heavy-duty machinery. Their adaptability, advanced manufacturing processes, and the variety of materials and surface finishes available make them a versatile choice for a multitude of applications.

In rotary applications, such as switches, torsion springs play a vital role. They provide the necessary torque to ensure that switches move smoothly and stay in their desired positions. Torsion springs are integral in these applications as they allow for precise and reliable operation, guaranteeing proper electrical contact and functionality.

The advanced manufacturing capabilities of torsion springs are a testament to their versatility. The use of advanced CNC (Computer Numerical Control) coilers allows for the creation of sophisticated shapes and forms. These coiling machines can produce complex torsion spring designs that meet specific requirements while minimising the product's footprint. This is especially advantageous in modern engineering and manufacturing, where space constraints are often a critical factor.

In drawing up specifications for torsion springs, observe the following points:

  • Diameter, stating whether inside or outside dimension.
  • Size of shaft or rod over which spring operates.
  • Number of coils required, and state whether right- or left-hand.
  • If the spring is assembled under tension, state how many turns are required to produce initial tension and the number if turns required beyond the initial point.
  • State how rapidly the spring operates
  • If required to carry a certain weight, specify how far from the centre of the coils this weight is applied, as leverage must be computed accordingly.
  • Show angles of arms by number of degrees of arc and show length of all bends and diameters of all eyes and hooks.

Consider that each turn will reduce the diameter and allow sufficient clearance between inside diameter of coil and diameter of rod or shaft. A spring which binds on shaft will break or set.

Consider also that each turn will elongate the coil a distance equal to the thickness of the wire of which it is made; allowances must be made for this elongation; if spring is confined, by coiling with sufficient space between coils to permit this elongation; if spring is closed coiled, the surrounding parts must be far enough apart to allow this movement.
