Hi,
this is a video about the basics of gear ratio. The video is definitely boring if you already know how gear ratio works, but could be interesting if you don't. I don't know if it's understandable, though.
Enjoy watching,

When watching the video the second time, I noticed that the video is a bit too fast... If it's also too fast for you, you can slow it down in the settings (then it's longer than 4 minutes, though). The most important part is only 30 seconds anyway.
I liked this video, but something missing. Can you (2in1 Bricking) tell me is it ok. I don't beg for views, just giving new info.. kzhead.info/sun/Z7eSnphorHSLpq8/bejne.html
Ok
Mechanical engineering student. You got it pretty dead on. A few important things to remember though, when output speed is increased/decreased relative to input (changing ratio), the output torque changes proportionally. A 2:1 ratio will spin twice as fast with half the torque, and a 1:2 ratio will spin half as fast with twice the torque. Also, worm gears can't be backdriven (so by trying to spin the gear you cannot spin the worm)
It might be important to clarify that, while chains and belts do maintain the same gear ratio, the gears rotate in the same direction, rather than the opposite direction they would rotate in if they were directly linked.
Also worth noting that the belt can slip. This is a bad thing in a mechanism which demands synchronisation between moving parts, but it can be used offer overload protection (a "mechanical fuse"), e.g. between a drive and its mechanism.
Belts can be crossed between the pulleys to reverse the direction.
Thank you! This has been a super helpful video! It's to the point and simple. Almost all the other videos I've seen on gear ratios are confusing
You're my favourite lego youtuber, i got my inspiration to start making motorized things and understanding so more mechanisms 😁 ex:car
I get a lot of help from your videos. Thanks.
So this is what Twitter users mean when they say "Don't care + didn't ask + *_ratio_* "
Thank you much I really need this
Very interesting and useful
Thanks I need this
This is great info to know, I was never taught the multiply gear ratios of stacked gears thing, its nice to know. Why is the worm tooth gear diameter only 1/8?
Good point. The gear ratio is only 1:8 with a 8-teeth gear. He mentioned correctly in the video with one turn the worm gear moved one teeth. (Simply explained and for me eye-opening). So with that 24-teeth gear in the video it is a 1:24 ratio. And of course it can never be a 24:1 ratio. So the wormgear is very useful to reduce ratio’s.
Pas mal le cours de SI
RESPECT❤❤❤❤❤
interesting 👍🙂
Short but shoot!)
