I'm very lucky to have found this channel, thank you for your generousity to share valuable knowledge. I have a question and wonder if someone could enlight me. Considering a gear train system, for ex. 3 gears. If the first two gears are design with profile shift, making an operating pressure angle, say 30deg, differed from the standard pressure angle--20deg(from gear cutter). Is it required that the rest of the gears in the system, for ex. the 3rd gear, be designed with the same operating pressure angle? or the rest of the gears can be designed with any arbitary working pressure angles as long as the base pitch is the same with all gears for them to mesh. Thank you!
The 3rd gear in your example does not need to share the same operating pressure angle as the first two, provided that you use the same gear cutter with the same standard pressure angle of 20° while manufacturing! You will find more information in the linked video: th-cam.com/video/RgMSsQApYIk/w-d-xo.html
@@tec-science Thank you. I now understand that the gears with the same maunufacturing pressure angle can be meshed at different center distances, resulting in different operating pressure angles.
This channel is a Mechanical Engineer's paradise
Thank you 🙏🏽
I'm surprised about how little views this has. It's really well explained.

Can you please make a video on "minimum number of teeth to avoid interference"?
like I said: th-cam.com/video/bol1U0BHcew/w-d-xo.html
Please explain interference in gears
See the video "Undercut of Gears"
