Spreadsheet with calculations

Spreadsheet with calculations

I'm looking for a post on this forum, where somebody said that a person named Emil (if memory serves well) might no longer be with us, because his website has been removed, but before that happened the author of the post had been able to save some spreadsheets from that site.

Thanks mfgenggear!
I really enjoyed these sites. I've seen a 66 MHz precessor requirement, pages last updated in 2015, DOS programs, DXF version 12. It was a nice experience, bringing back memories from the past. The spreadsheet (or, as it turns out, a little exe file) was just one of the things I remembered about that post I was looking for.

It's interesting to see a program completely ignoring the trochoid section of the tooth, simply replacing it with a straight line, which may lead to serious interference related problems, making that gear profile unusable. The program is online for so many years and no one ever complained?

RE: Spreadsheet with calculations

Lately I found several web pages for designing the gears. One of them is


I did not check for accuracy of their calculations, use it carefully.
I think that eventually we could create a list of similar services/apps with our own notes about them.
