Failed Connections in an Assembly

[ejyuhas]

Greetings, all! I'm kinda new around here, but not new to Pro/E...although some days it feels that way!

Anyhow, I have an issue where I am assembling a conceptual solenoid-linkage using connections. However, they are failing to some extent.

Here's the description of what's going on in the picture: The pink gear is assembled to the shaft using Cylinder. It moves axially 22.225mm and rotates 360 degrees freely.

The blue trunnion collar is assembled to the pink gear using Cylinder and moves along with it. It is also Aligned to the centerline and Aligned from its bottom surface to the top surface of the pink gear.

Next, the green bar is assembled using Cylinder at the fulcrum, and then to the blue trunnion collar using the Slot connection.

With these assembled, I can hold down Ctrl+Alt and pick the green bar with the L Mouse Btn, and the linkages and gear will move up and down like I want it to.

Now, when I assemble (or attempt to assemble) the solenoid plunger to the other slotted end of the green bar, the whole assembly fails to move as it should. Seems like the connections are fighting each other and it's frozen.

I've tried every combo for the other slot: Bearing, Slot, etc. to no avail.

Any suggestions? Let me know if you need more details...

Thanks and best regards,

Edward

The distance is changing from one end to the other end of the green bar; this is why the green bar is locked. The best way is mate the two surfaces (cylinder) green bar to the orange in the middle where the green bar is hinged, and then align the green bar to the orange mount....either by surface or datum plane to keep it centered....then use the point on surface or suface to surface on both ends of the green bar....all you need is one constraint on each end of the breen bar....theses ttwo ends will float or slide along the inside flat surface of the slots and the other surface of the two parts on each end. Hopefully this makes sense. I use to do this awhile back and it works. I have been away from Pro/E for a couple of years, but I do remember doing this many times. I hope this helps points you down the correct path.
