Question

Failing Connections in an Assembly

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...for the record I'm using Wildfire 4. Thanks and best regards, Edward

Do you want the plunger to control the movement? If the blue piece is assembled using cylinder & is constrained as you say then you can grab the green bar & move within your limits. I would use a pin constraint to connect the green bar to your plunger. I am assuming that your plunger is a two part assembly with a cylinder connection to control the movement of it. With the failure you're describing it sounds like there is a conflict with your cylinder constraints.

Mike,

Yes, the plunger shall control the movement of the linkage assembly. I've tried connectiing to it using Pin, but it still fails.

For the record, I've also tried changing the green bar's fulcrum to Pin, but this also fails.

I appreciate any other insights you may have...thanks for the help.

Ed

I would start by assemblying the plunger to the green bar first & get that working. then add your connections & eliminate the problem. I have had many problems like this before you just have to go back through it. Let me know if you are still having problems & I can look more at it tomorrow./
