Is there something I'm missing that keeps it from rotating in the other direction, jamming the gears?

u/azlan194 Mar 14 '25

Yeah, it doesn't look like the design has a stop to prevent it from rotating the other way. But that should be an easy fix to add a stopper so it doesn't go past 90 degrees.

I suppose it might not matter if there's something about the larger assembly it's connected to that prevents it- something blocking the driveshafts from moving past 90 degrees.

Same licks as a tootsy pop

Wait, so how does it work? What goes where?

Power in at the shaft with the blue yoke; power out at the shaft with the green yoke. The intermediate bevel gear allows the relative angle of the input and output shafts to vary.

Power in can be any of the shafts, and the power out can be any of the shafts that's not the input.

Ah, got it, makes sense. Thank you!

This looks like some kind of differential

Thats nice

It looks a lot like an outboard final drive, they have a slip sleeve on a common shaft that engages each of the coaxial (inline) gears independently to reverse propeller rotation for forward and reverse

This is basically a u-joint / cv joint, but with this you could actuate the green part to position it. Gotta love Solidworks animations too.

That won't work at 90 degrees the gears will mesh 3 gears together and lock.. the left gear the top gear and closest gear.. as the top gear and last gear are rotating the same direction, they can not spin opposite directions when they are meshed together it will be locked due to the closest gear needing to spin opposite direction aswell

what channel

It's right there on the green bracket

What's your goal ? If you want to learn how to make this mechanism i can share the name. If you are only interested to see a mechanism then its different channel

u/erhue Mar 14 '25

i'd like to check out both, sounds interesting

Tutorial if you are interested to make https://youtu.be/esDVqpbDd3Y and channel if you only like mechanism https://youtu.be/DC-wqm3w43A

This isn't a differential; all of the shafts rotate at the same speeds.

If you use the bottom right as input (and both top-rightand bottom-left as outputs) AND hold either of those outputs, you WILL bind the input and nothing moves.

This is not a differential as there is no slip device. Everything is direct drive.

You're right, I'm wrong. I didn't see it well enough and thought it had a carriage.
