We want to add a Chain-Link.
The Chain-Link is represented by one of the Parts in an RPR Dyad.
We add an RPR Dyad between a Point on Slider-Set 1 and a Point on Slider-Set 2.
As always, a Dyad has two Parts and three Joints.
• | Add a new Part and join it with a Pin-Joint(R) to a Point on Y-Slider of Slider-Set 1 |
• | Add a new Part and join it with a Pin-Joint(R) to a Point on Y-Slider of Slider-Set 2 |
• | Join the two new Parts together with a Slide-Joint(P). |
The two Parts and three Joints make the RPR Dyad.
We use the Part that is joined to Slider-Set 1 as the 'Tool-Part'. We can add a 'Solid' to this Part.
Remember, Dyads always have two Parts and three Joints. Add an R-P-R Dyad between Slider-Set 1 and Slider-Set 2 This dyad is: R(Pin-Joint) - P(Slide-Joint) - R(Pin-Joint) |

The two Pin-Joints are the R joints in the R – P – R dyad We need a P joint to complete the dyad. P = Prismatic-Joint. Confusingly, we call a Prismatic-Joint a Slide-Joint. |

The Slide-Joint completes the RPR Dyad The Part-Outlines become Green. When you cycle the machine, you will see the RPR Dyad move with the Slider-Sets. To show the length variation between the Pin-Joints:
The length variation between the Pin-Joints is from 100mm to 93.55mm. |
