Ring gearing was Gearbox efficiency while back-driving
Side topic:
I have read that the Wehrmacht's tanks, esp. the later ones that were so large, suffered badly from final drive failures. So much so that a road march of them for any distance would disable say 33%. This helped me better understand Allied anti-railroad tactics...forcing them onto the roads. [They also lacked tank retrievers of enough strength to salvage them....] The failures were because of 2 basic reasons: they lacked sufficient chromium to fully harden the gearing, and the second was my question..... This source (that I now can't find again...) said there was a way to better design/machine the ring gears needed, but Germany lacked the tooling/resources to use that approach, and instead used less strong methods. I inferred the better way needed more time or a better mill but beyond that, I don't know. I'm curious about what that might have meant, and wonder if anyone can speak to gear design issues... -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |
