Spring in SolidWorks


In this tutorial i will make a torsion spring the same as you can see in my models. I hope it will be halpefull for you.

  1. Step 1:

    Part. Choose top plane and start. Draw a circule D:3,60 mm and go under Features and choose (under Curves) Helix Spiral. Pitch is 2 mm and we will have 13 Revolutions. OK

  2. Step 2:

    Then choose Front plane to sketch and draw a centerline from the center up. Then draw a line and and choose 3 Point Arc and draw 2 half circules. Then draw a centerline like in the photo. Angle: 45 deg.

  3. Step 3:

    Smart Dimensions and close the sketch.

  4. Step 4:

    Open 3D sketch. Select Spline and draw a line like in the photo.

  5. Step 5:

    Then select the Spline and Line (hold Ctrl) and select Tangent. See the photo.

  6. Step 6:

    close the sketch. Choose the front plain and make the same on the other side.

  7. Step 7:

    Close the sketch and open 3D sketch Select Spline and draw a line. See STEP 4 and 5.

  8. Step 8:

    Now exit 3D sketch and go to Features and select (under Curves) Composite Curve and select all and OK

  9. Step 9:

    Now choose a plane (Reference Geo.) and select the Edge and Point like u see in the photo. and Sketch on that plain.

  10. Step 10:

    Draw a circule D: 0,8mm and close the sketch.

  11. Step 11:

    Features and select Swept Boss and select the circule u draw in the step 10 and the curve.

  12. Step 12:

    Hate to mention this, but this is an extension spring, not a torsion spring.
