Broken Axle

Do any of you know how to get the gears off because frankly, I really want to be able to keep this axle sorry the picture is so bad.

What exactly is wrong with it?

I’ll get a better picture up in a little bit but the thing is the axle twisted if you can see on the sides of the gears.

WOW…dude, I don’t see any way you’ll get that axle off clean…Unless you dremell (cut) all the way around the sides of the gears…Did you just want to keep the axle as a trophy? Thats what we did last year. Heck, if you do something that terrible, might as well keep it, right?

Oh, and I can honestly say that I have NEVER seen an axle twisted that badly, I applaud you, my good sir!

Oh, WOW. That is crazy!

I have never seen an axle twisted that much before.

I would just keep it as a Building Trophy.

If not, I really don’t see another way to get it out unless you use a dremel.

Amazing bro!

I have several gears from last year that are completely shot through with cracks.
Another add on to what snuss said (same team) we completely mutilated a potentiometer in the process of trying to dremel it off
Anecdote time
Finals match 2 us middle school national championship our gear shattere d and we had to take the whole thing apart and put it back together in 3 minutes before match 3
happy Result: Total descoring domination by team 985B

I remember that. I was on the other alliance that lost to you guys.
Ah well…

I think when we did that we used a pair of pliers and pulled it off as we were twisting it. It will require some strength but we managed to save the axel.

Here’s some more pictures if you guys can think of anything I just want the axle as a trophy.


You guys had Some good robots
It was a hard fought match

Now that’s a lot of torque. What was your gearing?
If the gears are shot, I might try beating it with a hammer until the gears break the rest of the way off. If you want a more civil solution, then the dremel suggestion should work fine. With an axle that twisted, I think it would be difficult to just pull the gears off.

It was the smallest gear to the largest gear with a 393 on each side

The way I look at it, either the Axle or the Gears need to be cut.

Option 1: Use a saw or dremmel to cut the axle as close as possible to the gear.

Option 2: Cut the gears off. Based on how much that axle is twisted, I find it hard to believe that the square holes in the gear are in good condition.

Why not just leave it as it is? Too bulky maybe?
Its not likely you’ll be able to salvage the gears anyway, unless you used locking bars.

We had a similar thing happen to us last year (not close to that extreme). We found that it was caused by having too much force being put on the axle, so if you are going to replace it, either reduce the amount of force that that axle is going under (eg. make mechanism lighter if that axle is lifting it).

If you are really wanting it to be the same, add more gears to spread out the force on the axles. It really helps a lot.
