Maybe this is something you are looking for: 2012 SOLIDWORKS Help - Gear Mates
After you created the mates you can make and run motion studies and you should be able to analyse the timing of the gears
Thank you Bryan, I will look into this but what I'm after is more of the result when for example a set of gears and chains and trying to get the timing do on the output " or the last gear to match or a desire time to turn lets say 2 rpm. I just hope that I'm not confusing. This is my first time traveling down this road.
