 Boy you guys try to make my job harder every year. - Al Skierkiewicz [more] |

If this were to be constructed it would function to my knowledge at least. There are there still some things that need to be added. I would like to make it more compact, add mounting points, etc. Does anyone have any idea how this could be condensed? I am trying the West Coast Products style of enclosure but it seems too open and asking for a finger to get caught. Any ideas? Thanks for supporting my project.

You could do something like 192 did with their gearbox to keep the finger hazard lower. However, that would imply that you have enough meat on the gearbox side plates to drill and tap a hole to bolt on some thin sheet aluminum to cover the exposed gears.

I could do that, it is all 1/4 plate alum. Thank you

Will you be posting a .step of this? Could be easier to give feedback that way.
One thing I notice about the design is that it appears that it would require you to take the entire thing apart just to replace the motors. Maybe something to think about in future revisions.

If the plates are getting milled (As opposed to waterjet or laser cut), you could also leave 1/16" or so of metal in the bottom of all the pockets. It won't weigh much, but will keep fingers out.
Totally awesome design by the way. I have a feeling my FTC team will be making something similar for next year.

Awesome gearbox so far!
I just opened up the step file. Your construction technique is similar to 192's gearbox from 2012, but you currently don't have any hard connections. If you look at theirs (though I'm no expert on it, I've just seen pictures) they still have some bolted connections. While it looks like you're going for a press fit, having some hard connections would be wise. Reliability and durability is key on gearboxes, especially your drive. The last thing you want is one of those plates falling off.
Also, as far as condensing it goes, you could cut down the shafts on the CIMs, which would allow you to pull everything in some more.
One last thing, as far as face-mounting goes, the sides extend some distance past the front. It's not a big deal, but it may annoy you a bit if you want to face-mount these.
Other than that, great work. Can't wait to see where this goes!

Is it possible to put both motors on one side so that you can reduce the overall width? Make one motor horiz and the other under it on an angle - same site.

If you feel like driving 450 miles to SVR next week I can try to have a 2012 gear box there. Let me know by Monday and I will arrange it. This years is even nicer.

I've run into a myriad of different issues while attempting to design my own worm drive, so seeing how you guys were able to accomplish it would be amazing!

If you need any help with your worm drive gearbox I’m sure Joey Milia would love to help.

Can't wait to stop by 192's pit.

Okay here comes V3, some of the bearing holes became overly sized for some reason and they will be an easy fix but I want to go to bed lol. I also need to add a 3:1 third stage to correct the ratios because as of right now they are way too high. It also now mounts to the KOP frame through 4 tapped holes on the face that line up with the toughbox mounting holes. Let me know what you think.

Re: pic: Next Revision
V3 is looking good!
A few things though:
1. To make facemounting easier, I would go one of a few routes: Put the four bolts holding it together in through the back and tap the front plate (this would give you a flush, flat front) or I would use countersunk bolts on the front instead. The other option is to just have holes for the bolt heads to fit through on the spot you're mounting this. Generally, your mount will be a lot more snug and reliable if the face is right up against the surface you are mounting it to.
2. You probably already know this, but just to remind you, you're going to need another spot for a bearing on the front plate if you intend to add a third stage.
This is a beautiful, elegant gear box. Awesome job on it!

. As for saving space I am making this box with the intention of making it easy to tuck away and less awkward so I could mount the motors closer together but I choose not too. Thanks for the feedback.
