6-Bar Kinematic-chains - R-R-R+R-R-P

Objective of the Tutorial

The objective of this topic is to:

continue to demonstrate how easy it is to add dyads to build more complex kinematic-chains

continue to demonstrate that the Pin-Joint and the Slide-Joints do not necessarily use the CAD-Line and the Points at its ends.

add the R-R-P Dyad.

Remember, there are 5 planar Dyads.

These are kinematic-chains with six-bars. It is easy to add another dyad to assemble kinematic-chains with eight-bar. And so on, to assemble kinematic-chains with 10, 12, 14, ... and more Parts.

Watt and Stephenson 'Slider' Mechanisms


This is called a 'Watt Slider `'.


This is the 'Stephenson Slider 1'


This is the 'Stephenson Slider 2'

Four new Mechanisms...


The next four images show more mechanisms.

Each begins with a standard four-bar mechanism, to which we add an R-R-P Dyad.

In addition to the four shown, it should be clear to you that you can reverse the 'R' and 'P' joints.

If you want to do this yourself, you can either build a new set of mechanisms, or simply delete the joints and re-join then to the 'opposite' Parts.
