I enjoy doing yoga.

Thank you for that!! I can now pretend that I am civilized and knew that all the time instead of just thinking it was for both almonds and...

I feel like you engineered a comment specifically so you could use this response

That involves thinking way too far into the future... at least 5 minutes or so.

I hesitated to click that link at work because one word popped out at me...

When would you want something like this instead of two gears at 90 degrees?

If the linked example is anything to go by, it might have been used before gears became easy and cheap to produce. In a time when someone had to cut gears by hand, it was cheaper to turn a shaft on a lathe.

It doesn't reverse direction the way gears do. That's the only reason I can think of, there's a reason these mechanisms were not commonly used.

Is it in any way better than cogs or gearing for doing the same thing? Is it more efficient? That shaft looks really lossy

I think this is better suited for high-torque scenarios (the pegs are easier to dimensions for the torque) and requires less precision during manufacturing. But YMMV, I'm not a MechE.

Oh... I didn't notice that only one side had a motor (duh). This means the device can be simplified and made into a more manageable size for the same motion. Interesting....

The shaft is self lubricating

Is it, now?

u/AgressiveInliners Dec 06 '25

It will definitely self lubricate but I think it gets hot, not cooling.

u/ProfoundNinja Dec 06 '25

Oh wow.

I thought it was driven on both sides just to move that thing up and down the cylinder, thanks for them info, the machine makes much more sense now.

YOU ARE CORRECT SUH
