What is conical spring?

Conical springs are compression springs that derive their name from their distinctive cone shape. The unique conical spring design offers the advantage of a reduced solid height in comparison to straight compression springs. As a result, conical compression springs can provide a near-constant spring rate.

What are conical springs used for?

Definition: Conical springs are compression springs which are helically coiled round wires forming a tapered or conical shape. They are used to provide balance and reduce the solid height by the coils telescoping into each other.

How do you make a conical spring?

  1. In a conical coil spring with a fixed pitch angle, R and n’ (= θ / 2π) are associated with the following formula.
  2. The deflection before the coils are compressed to the ground is calculated by integrating dδ = (2πφ / ν) R2dR, where ds is eliminated from the two formulas dδ = Rφds and dR = (ν / 2πR) ds, from R1 up to R2.

How do you make a helical in Solidworks?

You can create a helix or spiral curve in a part.

  1. In a part, do one of the following: Open a sketch and sketch a circle. Select a sketch that contains a circle.
  2. Click Helix and Spiral (Curves toolbar) or Insert > Curve > Helix/Spiral .
  3. Set values in the Helix/Spiral PropertyManager.
  4. Click .

What is a constant rate spring?

When we talk about variable rates and constant rates, we are referring to the rate of force acting upon the spring, or “deflection.” Constant-rate springs have a uniform rate of deflection because they are the same diameter from top to bottom.

How do you find the pitch of a spring?


  1. Closed Ends. p = (L–3d) ÷ Na.
  2. Closed and Ground. p = (L–2d) ÷ Na.
  3. Double Closed Ends. p = (L–5d) ÷ Na.
  4. Open Ends. p = (L–d) ÷ Na. p = pitch. L = free length. d = wire diameter. Na = active coils.
