Maybe this should have its own heading, like "Cog Belt PSRUs". I've been collecting pictures and descriptions of cog belt PSRUs just for my own information, looking at different examples. Plus looking at other types of PSRUs, this is the way I started to understand that COG BELTS CANNOT BE USED TO ISOLATE TORTIONAL VIBRATION. One thing that bothered me - unless most of the anti-vibration couplers were very cleverly hidden, I did not see any at all, because the input cog pulleys all looked like they were mounted directly onto the flywheel. How come? Unless I'm really, REALLY missing something. What say you?
