great job displaying the exact equations necessary to produce a gear that can be changed with only a couple variables. Could you produce a video teaching us how to build equation driven helical bevel / miter gears?
Hi there. This is an amazing tutorial and has come in handy for me more than once! I was curious and hoping that you might be willing to make a similar tutorial for the internal version of this? I've been hunting around and have yet to come up with a decent tutorial! Either way thanks for your time.
Your video's good, but when I tried making my own spur gear based on the number of teeth and chordal pitch (the size changing accordingly), with a contact angle of 20°, I couldn't have more that 41 teeth because the base circle was getting smaller than the root circle. What can I do to fix this? I'd like to be able to have at least 50 teeth on that gear...
Hi, I'm trying to use this tutorial but I'm having trouble. Every time I try to do the first centerpoint arc (9:06) my angled construction lines and equation driven spline become under defined. I have no idea why this is happening, please help?
+Lewis Holmes I have done this way many times but didn't get such problem ever. Try to draw the lines/centerlines/arcs without snapping to the appropriate edges and then apply appropriate relations manually. Also make sure the ends of invoulte curve are defined completely, if not, then apply relations manually between involute curve and base circle (bd).
+Sonu Singh Hi Sonu, Thanks for the quick reply. What relations should I apply to the involute curve? It's strange because as under defined I can move the curve about, but it always snaps back once I let go. In other words it does still work but it just isn't fully defined. I will try again and apply all the relations manually. Thanks.
sir, I was trying to make gears of different configuration for my project in one of the gear I have to make 60 teeth, module 2mm when I made changes in the equation I found the error that is -- "db" is smaller than "pd-2*b" ..... what should i do (pressure angle in 20 )
it seems that whenever we change values the form of a tooth change. what should i do if i want to make two gears with different diameter circle and the same form of a tooth ? because i want to make a smal gear that can move an other big gear with a 160mm addendum circle diameter but i dont know how to do that because the small one hasn't the same tooth as the big one. can anybody help me please ?
Hello. Thanks for video. How do you add equations on a fly? I have to open equations window then click on dimension and then type formula into equations dialog. But you somehow type formula when making dimension or setting up extrusion and instantly save it as an equation. Is there a hotkey for this or any checkbox in solidworks configuration? Or may be its just SW version? Mine is 2016.
Vesrand define your variable beforehand in the equation box, then use them on afly by typing equal to sign (=) followed by the equation. As soon as you type you will be able to access all the global variable. If you are calling any predefined variable, make sure that variable is within the double quote (" ").
during the process of selecting the faces to circular pattern, make sure that geometric pattern is ticked before accepting it, if that doesnt work, do the pattern first, then fillet after
They are start and end angle (in radian) and they control the start and end point of the involute profile. 0 ensures starting the involute profile from the base circle itself and 1 ensures that involute profile crosses the addendum circle. If your involute profile doesn't cross the addendum circle then you can replace 1 by any higher value or vice versa. Try Changing these parameters on your own for better understanding.
The explanation was great but the zooming in when writing the equations and variabes has just earned you an special place in heaven
This is the best explanation ive seen for involute gear profile design
great job displaying the exact equations necessary to produce a gear that can be changed with only a couple variables.
Could you produce a video teaching us how to build equation driven helical bevel / miter gears?
it is best presentation to draw spur gear in a good involute method. Thanks,
Thank you. This is the best explanation.

` Hi Sonu Singh Rajpoot
i am dying for your feedback for the question!
hi, im using solidworks 2013 and when i enter values it shhows incorrect syntex. what to do ?
thank you from Ukraine =)
so dificult but necesary,!! excelent! thanks

It's because of you didn't specified value of alpha
sir, I was trying to make gears of different configuration for my project in one of the gear I have to make 60 teeth, module 2mm when I made changes in the equation I found the error that is -- "db" is smaller than "pd-2*b" ..... what should i do (pressure angle in 20 )
what if i wnat to do an internal spur gear? given the teeth and the module, how can i work out the pitch? is it the same equation?
please give me tutorial make internal gear with equations
it seems that whenever we change values the form of a tooth change. what should i do if i want to make two gears with different diameter circle and the same form of a tooth ? because i want to make a smal gear that can move an other big gear with a 160mm addendum circle diameter but i dont know how to do that because the small one hasn't the same tooth as the big one. can anybody help me please ?
kaioid For meshing of two gears the only compulsion is both gears should have equal MODULE (ratio of their respective diameter and teeth).

Oh thank you for fast reply. Yeah that works.
For some reason trying to circular pattern with the fillets in the gear doesnt work
same problem. did you find what was the issue?
during the process of selecting the faces to circular pattern, make sure that geometric pattern is ticked before accepting it, if that doesnt work, do the pattern first, then fillet after
hope this helps
thanks for info. just tried those options. fillet after pattern worked for me.
why are 0 and 1 for parameter t?
They are start and end angle (in radian) and they control the start and end point of the involute profile. 0 ensures starting the involute profile from the base circle itself and 1 ensures that involute profile crosses the addendum circle. If your involute profile doesn't cross the addendum circle then you can replace 1 by any higher value or vice versa. Try Changing these parameters on your own for better understanding.
excelent! thanks
