whips nd chains mmmm lol

whips nd chains mmmm lol

whips nd chains mmmm lol

(OP)
Just being naughty lol
   Seriously tho my question is not exactly solidworks related but I do have a question about chains and gears.
   sprocket 1 is 200mm dia
   sprocket 2 is 100 dia
   First example  distance between sprocket centers is 1000mm
   second example same sprockets but distance is 500mm
which is easiest to turn???
   The reason I ask is a person I work with said that if you shorten the length of chain between sprockets it gets harder to turn (think pushbike)But i dont get it ???
Having modeled up a simple gear box with belts a while back and using gear mates what he said doesn't ring right ???
   The machine that we were trying to fix today has a lot of sprockets and chains and we think we may have to do some mods on it cool
   Thanks gurus

Ctr to Ctr distance doesn't matter, its the diameters (ratio) of the two.

Tooth ration only takes into account ideal power transmission.  There is more that can affect chain performance.
