Hey its simple if you make it in assembly. Design tab and Spur gear. You can edit all the properties from face width to number of teeths.

Hey, thanks for actually narrating! Seriously, it really means a lot. This video was so useful to me. I just wanted to quickly model a knurled cylinder for 3D printing with TPU. The measurements were not critical because it will only ever mesh with flesh! I was trying to create the circular pattern in the sketch but it wouldn't extrude properly. Your technique did the trick.

I was hoping for a verbal walkthrough of making a true involute curve for the tooth, as inventor STILL doesn't have this feature built in. Making a gear like this with grossly approximated tooth pitches isn't actually useful, you can't use this gear for anything important, because it will never mesh correctly with any other gear teeth.

At the risk of pissing people off I have to thank you for your video. I am a total novice trying to learn this stuff and found your video very easy to follow. Maybe rather than criticizing you they should try to make their own video showing the "right" way of doing this. There are a lot of videos out there but frankly either they have no audio narration, just annoying and distracting music tracks or people for whom English is not their first language narrating so following and understanding the videos is very difficult or impossible for newbs like me. So thank you again and if you could make one on bevel or helical gears that would be greatly appreciated.

Thank you 🙏🏻 it is really amazing explanation

Learning how to 3D model for 3D printing. Very Helpful. Thank you

How do you match the gaps between the teeth so that the gear could fit in if I ever wanted to resize the gear diameter? 🤔

that works too, however by subtracting material it might make using the circular tools little more trickier. But that's the great thing about inventor, there's multiple ways to achieve the same objective

hey john, congratulations! could you please create a video of creating a ring gear?

A better way to model is to cut the gears from the model, not add the material for the teeth. That way you can suppress the teeth for a simplified view, whereas if you were to suppress your teeth here now the simplified gears would not intersect in the assembly. Plus I would have started with a revolve that includes all turned features (gear and hub) on such a simple part, or on more complicated, then as much as possible all turned features in the main revolve, until it doesn't make sense, then cut away material, more like you'd really manufacture it, instead of adding and adding material unlike it would be manufactured (assuming not additive manufacturing).

How will i make a chain and can i use some tool to resize the gear example is a gear train with 2 gears one gear is smaller and other is bigger the big one has 30 T the small have 20 T only difference is the teeth and the diameter

Thank you sir may you please help with rack and how we assemble it to this gear please

ty man this video awesome... i am 3rd year mechanical

Which software u using??

is this a spur gear or a ''look like'' spur gear? lol

awesome work!

how to convert this spur gear from inch to mm ?

that's not a spur gear

so helpfull~

> Sorry, but that is not how one creates a toothed wheel Create a sprocket from a involute.
