The cam drive on the NSU Supermax, 4th pic from the bottom, is interesting (item 2 in the illustration). It consists of 2 conrods phased at 90 deg to each other (avoiding a dead spot at the end of the stroke). Smooth, quiet and efficient, and despite initial impressions, purely rotary motion so it doesn't add to reciprocating weight. I believe it was quite expensive though.
The art work in these cut-a-ways is beautiful. Each one a master piece of its own.
ReplyDeleteWow! I've seen textbooks & repair manuals with less detail!
