Hello,
I am trying to model a gear train in CosmosMotion 2008. There arefour spur gears with 6, 7, 8, and 9 teeth. The gear teeth use aradius instead of a true involute shape. The gears have about a2.00 inch pitch diameter. The fastest gear is driven by a motor at10 rpm. The motion study property manager has "use precise contact"checked. I've tried frame rates uo to 800 frames per second,accuracy from .0001 to .000000001, Integrator types Gstiff, Wstiff,and S12_GStiff.
No matter what I've tried: The assembly starts with clearancebetween the teeth but after about a quarter of a revolution theteeth penetrate each other about .010 inch (as seen in the graphicdisplay).
Thanks for any suggestions or advice?
