alright so ive searched all over and tried suggestions from previous posts on this site. I have a setup of gears in a drill speeder assembly. The shaft gear spins 2 smaller gears on either side which are attached to a gear below those 2 which drive the spindle gear. to further clarify my setup; In the center you have the shaft gear, on each side of that gear are 2 smaller pinion gears which are attached to an intermediate gear below. These 2 gears are on either side of the spindle gear. I can get the 1 smaller gear to drive the shaft gear but i cant get the shaft gear to drive the 2 pinion gears that eventually turn the spindle. If i don't constrain the pinion gear to the intermediate gear i can get the shaft gear to spin the pinion gear. I constrained planes between the pinion gear and the intermediate gear in order for the intermediate gear to spin when the pinion gear spins. Ive tried an angle constraint between the pinion gear and the shaft gear with a motion constraint but does not work. And this is only when trying to get one side to work, not sure how to get the opposite side to act in the same manner. I hope i made my setup clear, hard to put into words without a picture of whats going on. Any help much appreciated.

I can't say that I can help with your gear issue....but Giroux is probably my favorite Flyer since Brindy was traded.

oh absolutley, i hope he's a flyer for life. So fun to watch.

Attach your sun and planet gear assembly here.

Why can't you attach picture?

Oh misread the rules, thought it said i was not allowed to post files and i took that as any file include jpegs. So here is a pic of my setup.

Send me the files.

What version of Inventor do you have?

Sent you the email (subject: Mcad forums:Gear Box assembly). I have version 2010. Really appreciate your help on this, still trying to learn all i can about inventor. Im not familiar with how iam files open with out the ipt files on the same source so if it doesn't open properly let me know.

An iam file is simply a list of hyperlinks to the ipt files and a record of assembly constraints.
Without parts an assembly is useless.
I recommend you go through the Help>Tutorials before we continue as it is going to be difficult to communicate since I an running 2012 and you are running 2010 with limited experience.

Are running 2010 standard or 2010 Professional (with Dynamic Simulation)?

I am running 2010 professional with dynamic simulation. Its the education version you get from autodesk. I didn't think 2012 was that much different from 2010, least not from what i saw watching youtube tutorials. I will email you a copy of the ipt files. I have a pretty good understanding about inventor, i am no professional and yes i am still learning but i am not a total retard either, even though it might seem that way based on my confusion about how iam files work. I have basic knowledge on the fundamentals. i have not had a whole lot of experience with dynamic assemblies ie gears. ive already learned the concepts that most of the help tutorials cover.

I am working my way through your assembly.
First thing I notice is that some of your sketches are not constrained and some are sick.
I haven't found anything (yet) that would keep the assembly from working - but when something doesn't work AND I find unconstrained sketches I start to worry how many things I won't (easily) find.

In this sketch you don't need the construction line and there should be a coincident constraint betweek the midpoint of the vertical line and the projected origin.
- you can drag the line a bit to the side to see that it is missing constraint.

You might go through this document

Notice the i in a circle in this sketch. Not good.
And the sketch is not fully constrained.

You did not send me the two Gear Generator sub assemblies so I do not know the pitch circle diameter (I can figure it out from the center-to-center distance).
You need to make visible the extruded Pitch Diameter surface.

Alright, would you like me to send you those assemblies?. Yea those sketches got out of control when i realized i needed to make changes after i was already done everything. The changes turned into a lot of contraint issues that i was partially unsure of how to diagnose and then i got all caught up in the assembly and forgot to go back and fix. I know i got a lot of learning to do, but i really do appreciate the help even though it seems to be a complete disaster for you. I will go though that document you sent me.

ive also gone though this file and constrained everything. No more "I"s
