How to assemble this model: Summary

1.Add a Gear-Pair so that one Gear orbits insides a stationary Gear, and the orbiting Gear orbits one time per machine cycle
2.Add a Dyad:
Join Part 1 of the Dyad to the orbiting Gear with a Pin-Joint
Join Part 2 of the Dyad as a Sliding-Part, to slide along the Base-Part horizontally
Join Part 1 to Part 2 with a Pin-Joint.
3.Add a Rocker to the Sliding-Part
4.Design and add a motion to rotate the Rocker
5.Add a Cam-Follower Roller with Profile to the Rocker
6.Add a 2D-Cam - select the Base-Part and the Roller Profile in the Rocker.

The key difference between Design 1 and Design 2:

... we do not know the motion of the Sliding-Part [Part 2]- unless we measure its motion.


The motion of the Sliding-Part is quite complex. It is a function of many parameters:

ratio of the Gear-Pair
The Base-Value of the Rocker that rotates the gear
The length of Parts

...and more.

The rotation of the Rocker to be a function of the position of the Sliding-Part.
