Re: pic: what is cooking
Well that's one heck of a reduction (in a fairly lightweight package too). But why the (what appears to be) 1:1 gearing on the last stage? Also, you should render that thing in Inventor Studio if you have it. It will look nice.
Also, nice job filleting all your corners. However, your machinist won't be thrilled with that really pointy triangle. What do you need to get in there, like an 1/8" or 3/16" tool? |

hmm...how to turn your CIM into a Taigene 101? looks nice.

...That's a lot of reduction. I also like the lightening method. However, as Sanddrag mentioned, you may want to make your corner filets a little larger, just to be friendly to the machinist.

I really like how well you've done the "spokes" out from the bearing locations. It looks just great. :)

Re: pic: what is cooking
Are you sure those spokes can take the torque of the final output, I'm no ME, but they look a little small to me. The big gears look about the same size throughout the gearbox, as do the little ones. So, lets say the little one looks about 12-15 tooth and the big ones look about 60. There look to be about 5 reductions, so I'm thinking a final output of 1.7-5.2 rpms. So, either turning swerve modules (seems a bit excessive) or some sort of arm? I might be a bit off on the tooth counts (hopefully not too far) but whatever the exact number is, that is one heck of a reduction.

Judging by Luke's calc of final output RPM which sounds about right....im guessing a telescoping arm mechanism or other arm mechanism...looks very cool tho

Re: pic: what is cooking
Lukevanoort you were close the large gear is 70 teeth and the small gear is 12 teeth the final out put is 2.2 RPM :D

But how can you test something like that...the only thing I know of is COSMOS and that is only for solidworks. I really like the wight reduction designs though and if there are no torque problems that is an amazing gearbox. |
Re: pic: what is cooking
Where are you counting a fifth reduction I count four... I had someone else look and they also only see four.

Round holes will be faster to cut and stronger to boot. True, you will probably want your machinist to machine down the gears since they require balance; but the frame? -------------------------------------------------------------------------- What do you plan on doing with your telescoping arm anyways? Any cool off-season projects a-brewing? Nice work. |
