I traced back to the revision from the date I posted the link:crossbreak wrote:There was once a complete table with all cases on Wikipedia, some fool deleted . I should have saved this table once. The german version still has a table, hope you can read ("Sonnenrad fest" means sun gear fixed, "Steg" means planet carrier, "Hohlrad" means ring gear): http://de.wikipedia.org/wiki/Umlaufr%C3%A4dergetriebe#Kinematik
Yes. That's correct.Whiplash wrote:If I understand correctly if I start with a 5:1 ratio, fixing the outer hub will deliver 6:1? That's great because I am hoping for lower gearing doing this!
I never knew fixing different parts of a planetary gearbox produced different ratios!
I'm looking at 4 MPH in low gear and like 17 in high with my 12 turn Mac
Having actually looked at your link, I'm not sure I have the table you're referring too... Sure. We can mine the revision history for the best material.crossbreak wrote:Awesome, miles! May we copy it to our own wiki?
