- Creating Spur and Helical Gears - Tutorial - SOLIDWORKS. This video shows not only how to create Spur and Helical Gears using SOLIDWORKS, but also how to add intelligence to the design and let SOLIDWORKS do most of the heavy lifting for you. This video relies heavily on equations. If you’ve never used equations in SOLIDWORKS, this is a great video for that also.

I have watched many videos on gear design and this video is by far the best explanation of how gears are designed and the use of equation tables to control size and number of teeth for a gear. The narrator speaks clearly, knows his subject and moves slow enough for viewers to follow the video. In my opinion the best tutorial on the subject I have ever viewed. Great teacher!
We are so glad you found this helpful!
This tutorial was amazing!!! So now, I need to build a pulley system that will lift my jaw off of the floor!
***** Hahaha this is awesome. Well done.
This is a great SolidWorks tutorial, with the one exception that these gears would explode in use. Gear teeth are nearly universally involutes, not circular arcs. SolidWorks even offers involute support. This can't be overlooked.
After the first impulse to agree, I googled it (but didn't get too deep into the matter) and found that actually the "Wildhaber-Novikov gearing" or "Circular arc gearing" seems to even have advantages over the common involute or zykloid teeth... But it is more complicated to manufacture - and so quite rare.
Anyway I guess that if someone is constructing "gears", he is going to buy them as standard parts. Or if he really makes them himself - he knows about involutes ;)
This is One of the best "How Tu's" of the power of Solidworks I've seen. Love the software and the schooling.
Holy Mackerel that was a great tutorial. I will have to watch your other videos. You are a GREAT teacher.
Wow, this video was great. Well spoke, directions and descriptions were clear also. Two thumbs up for me. Keep the videos coming. I like to follow along in solidworks and create parts to help me practice.
Probably the best explanation of how to make a gear, thank you so much!
Through out years of looking for a proper gears video, this is hands down the best of the best.
Well explained and simple to replicate in any CAD software.
Thank you!
this was the best gear design tutorial I have ever watched, so simple!
Literally the best tutorial I've ever seen. Great job!!!!
This is awesome. With equations you can even add conditions for the rest of the wheel, like making it solid or hollowed, the size and number of pins. Thank you.
This brought me back to earth and showed me how little I really know. Brilliant tutorial, more of the same, please.
I've only ever played with Google Sketchup and auto CAD from like ten years ago but I fully understood the entire vid. you're a pro and I appreciate your thorough approach and solid focus. I hope to be able to get into solid works and learn more from your vids
huehue "Solid" focus
Most brilliant tutorial to learn about creating gears in solidworks ... So elegantly explained... 👏👏
Awesome tutorial. Helps learn a lot, amazing when you know the software how powerful it becomes
I saw this video today saved on my hard drive. Wanted to find and like it. Thanks a lot for the tutorial
nice tutorial for using the equation functionalities however as a mechanical engineer here are some major faults in the design:
1- by definition the involute is never an arc, it follows sin and cos formula
2- the pressure angle should never be done as shown, it simply used to calculate the base diameter where the involute starts
3- the helical angle is also wrong, simply projecting a line is so wrong, it should be done with a "helix", the helix pitch depends on the helical angle and pitch diameter, for instance for 45 degrees its tangent is 1 so the pitch is 3.141 * pitch diameter
I didn't want to sound critical, but if you produce such tooth profile as indicated the gears will slide and won't roll.
they won't be efficient at all especially for molding plastic gears.
I have produced perfect gears geometries this way, it takes more time in the beginning but if you set your global variable as indicated it should be easy.
I will be happy to share my knowledge with the community
thanks
jean daher I had the same thoughts, jean. The method in this clip is wonderfully simple, and great for making realistic looking gears (as long as the "looking" is done from a distance) but it should be made very clear that gears modelled in this way are not functional.
Most people will not realise that the projected curve, in particular, produces a different result from a helix, and it is increasingly incorrect as the helix angle increases. A "crossed" skew-gear pair at 45 degree helix angle would make this very apparent, and the interference towards the ends of the teeth would be considerable.
A further problem is that, for a helical gear, the tooth profile needs to be swung around normal to the helix. Not that it matters for a "Not for production" visualisation of a gear.
+jean daher I am studying Design of Machine Elements, and one of my final assignment is to create a gearbox, which I have choose to use spur gear and I found your comments very accurate with what I am studying at the moment.Would you share how you have created perfect gear geometries? I am struggling at the moment in creating the shaft....
Sure, but as I said it takes some time upfront. SW is also limited since it always refers to the original coordinate system and disregard the new one. (I complained abut it, they admitted it but still not fixed)
1. start setting an equation for
1a-pitch diameter 1b- diametral pitch (module for metric) 1-c pressure angle
2. make a sketch for all relevant diameters driven by the equation, from previous you can set your number of teeth, base diameter, addendum etc.
3. now create an equation driven sketch, make sure you pick parametric with t1=0 t2=2*pi (it doesn't have to be 2pi but it is better to be longer than not enough)
set Xt=(base diameter/2)*cos(t)+(base diameter/2)*t*sin(t)
set Yt=(base diameter/2)*sin(t)-(base diameter/2)*t*cos(t)
you should have a full involute. after that just fix the curve, another bug with the software
the rest is up to you to make an extrusion based on that sketch and cut based on equation curve, create the cuts pattern from calculated number of teeth.
if you follow that you have a template that works perfect every time.
once you master that helical gear is similar however you cut the involute with a helical cut instead straight cut. the helix pitch will based on helical angle described in earlier post
hope that helps you
jean
Thanks a lot!!! Will give it a go today!
off chance that you will see this but i need some help with a gear design and wondering if you would be willing to freelance? 15t and 21t 3.25" on center
Such a life saver! Thank you so much. Great tutorial! Already Subscribed and Liked.
Really nice turorial... Helped me a lot. Thank you!
BEAUTIFUL explanation! Loved the video. Thanks for sharing
An excellent video! Thanks for sharing!
The best tutorial I've ever seen for spur gears
This was incredibly helpful! Thank you. I'm designing a 3D printed helical gear box and this just answered like 50 of my open questions.
We're so glad you found this helpful!
Very helpful thanks. I needed to sketch a gear at work today and although it was something I routinely did in minutes ten years ago it had completely slipped my mind! Thanks for the tips!
Thank you so much for this awesome video! :D
And again an awesome Video, thank you!
The best tutorial on the gears
Very informative thank you
Awesome tutorial!
MORE POWER!
Great video! Keep 'em coming! :)
Amazing tutorial, many thanks!
Great Explanation :) Thank you!
Dude... This is so damn awesome. You are a great teacher.
Thank you very much for this detailed tutorial. Even after 5 years, this is still a great tutorial to follow on when learning how to design gears in Solidworks!
Hi There! We are pleased to hear that! 👍 😃
Yes, it’s a great tutorial. I remember learning this in school, Solidworks class.
Wonderful tutorial to follow and learn.
Very clear explanation. Thank You.
That is great! Thank you for this excellent tutorial
Awesome tutorial Thank you
Really helpful, I learned a lot from this.
thanks for such a wonderful tutorial
That is really how to use SolidWorks. You are a true expert.
Excellent very detailed video
good video. very clear. thank you
great tutorial, very informative
Thank you very much for the lesson! It's nice to see some of the shortcuts that I've learned along the way can be done in a simpler more efficient way! Never used "derived sketch" before. Now I'll fully abuse thatcommand! :-)Can we see a tutorial on creating a continual "internal cam surface" that I can use in a motion study?
I only recently received a certificate as a SolidWorks Associate. This video was very helpful! Now making drawings for these two gear types won't be so troublesome.
Would love to see more like this tutorials !!!!!!
Your lesson is outstanding.
realy awsome tuturial!!
it was really help for my project. Thanks Mr. Jeremy.
Is is possible, if you could manage to produce a tutorial on worm gear? It will really help alot.
Very clear and precise instructions. Thank you! What adjustment do you have giving the solid a authentic material appearence?
The content of the video was very concise and to the point. Thank you for a well done presentation.
Awesome! Thanks a lot!
Clever tutorial!
Great! Thanks~
Great job showing us the tooth profile generation & a gear that can have the helical twist adjusted within a sketch or simply making reference to a global variable as tooth angle/twist.
Could you produce a video teaching us how to build equation driven helical bevel / miter gears?
great quality!
I am mechanical design engineer and honestly this is quite satisfactory video.
That is great to hear! Thank you for the feedback!
I'd love to see a video like this showing how to model miter/bevel gears.
You are an amazing teacher
Thank you for useful tutorial. Successfully goodness of life.
Great tutorial, do you have any video tutorials on worm gears?
love this
I learned a lot thank you
Terrific!!!
Dont forget that you can drop your driving sketch into every assembly and sub assembly, this lightens up the processing time in the main assembly and helps your computer to think in smaller chunks of information this helps stop crashes and opening and saving times.
Thanks a lot, sir
very good.... thanks alot.......
Thank you!
thanks for tutorial
do you made something like this tutorial for bavel gear?
Hi! Great video! is it possible to carve out a cyclic section (with one tooth) for a 3d cyclic FEM simulation?
nice presentation
Holy cow, best gear tutorial ever.
We're so glad you found it helpful Jesse!
just an FYI, the gear as modeled produced interference when mated with an identical gear of ~0.2mm according to interference detection features. It would not be functional. I verified the equation outputs to be sure it was not a replication error.
Thank you
Love Equations and love you 1000 times 💕
damn this guy just singlehandedly show you how to modelling gears the most efficient way.
I really like the way this was taught, I see a worm gear in the animation. is there a tutorial, you have posted, that shows how to make "worm" and "rack and pinion" gears
Can you please add a video on mating these gears too?
what is the name of that gold colored shaft with the grooves that enables the slider to move in that pattern? It's visible in the assembly at the beginning of the video.
Life saver !!!
that looks beautiful
Very nice tutorial, thank you very much. Just one small thing. At 6:39 you say the whole depth should be 2.40*m if module is finer than 1.25, and 2.25*m for coarser module. But should this not be opposite? I would expect a greater whole depth for a coarse module gear.
Greetings, Does this also apply to internal helical gears as well? Thanks
I applauded
I cannot thank you enough. 😊😊😊
Please put video also for bevel and worm gear.
Hi,
I have a question for you. Can you please explain how did you set the angle of the arc for helical gear to 10 degrees? did you calculate it? or did you just randomly set that to 10 degrees?
Many thanks
How do you calculate the center to center distance if you know what gear ratio and module you would like to have?
How do you make various boxes appear where your mouse is? What short cuts are those?
Can you link the previouse video please? Thank you
Great tutorial.
Thank you! We're so glad you found it helpful!
sir i need to know how to make helical gear with these type of equations if we know diametral pitch and number of teeth because these equations that u are using not working in designing helical gear with helix angle 45
if u provide this information it would be very helpful to me
Hi!, Is a very useful tutorial, but please tell me. What is the difference between this method and the toolbox option?
Can you please make a link to the gear assembly in the beginning
DUDE you are amazing :D I study mechanical engirenig and i recived more knowledge about gears from you than from my proffesor :D
(Y)
Very nice! However, i wanted to create global variables for everything and works! The only thing that didn't is the angle of the teeth. When i change in positive values, works fine, but doesn't when i try in negative ones. There is some trick to change angles in global variables?
If the gears are on the same plane, what angle would you use if you are meshing helical gears?
It would be great if there was a video on the assembly from the beginnning
Intresting tutorial sir, one doubt why you create one circle above outer circle
Thanx
