chain motion study

hey,

i am new and don't have a lot of experience in solid works.
I am trying to do a motion study with a simple chain/sprocket assembly but the chain always flew through one sprocket and petrates the other. the motion study properties are already set to 500 fps, max Geometry Accuracy and max 3D contact Resolution.
Any idea how to fix it ?
thanks !
