Top Reddit comments about Mechanical Gears:

They probably use a 90 degree gearbox to change the direction of motion. The gearbox probably has reduction gearing to make turning the handle easier.

u/marauderingman · 1 pointr/HelpMeFind

There are many specifications needed to describe those gears accurately. Have a look at these for some of the specs relevant to your application.

u/Strikew3st · 1 pointr/specializedtools

I have been thinking that same thing all the way down here, BUT- the thought just occurred to me. Would this tool be less awful if all but the furthest out pivot used mating teeth? Maybe like a bevel gear? I am still against it, anybody really concerned about a non-90 angle cut is still better off with a scribe..but what if? Just what if?

u/blargh12312312312312 · 1 pointr/CNC

That's an interesting concept. I wonder how I'd attach something like this to my rails. This requires more research.

I don't really know much about gears (or rack and pinion). Anyone care to offer advice on pitch, pressure angle, or whatever, for this purpose? It looks at a glance like Amazon has some options, though they're a bit expensive. This might be a future upgrade.

We use this worm gear in the woozi pusher: https://www.amazon.com/Ajax-Scientific-Plastic-0-82cm-Diameter/dp/B00EPQMKHQ/

u/WhiteStripesWS6 · 1 pointr/ender3

I'm guessing this is also the case. Maybe OP could swap to a new gear on the extruder first but a BMG clone is like only 22 bucks if OP want's to go that route. Maybe trying another slicer first is a good idea too.

u/wromit · 1 pointr/metalworking

Depth is 1mm along the side. The worm gear does have a key (threaded screw) but the shaft would still need a flat surface for the screw to hold on to I suppose. I don't have the equipment so I'll check if any local metal working places (Houston, TX) could help me out.
