To use this expression, first create and import two gears that mesh together properly. In order for two gears to mesh properly, the ratio of the difference in size between the two gears must equal the ratio of the difference in the number of teeth between the two gears. Once imported, decide which gear will be the Leader and which will be the Follower. Apply the Expression below to the Rotation parameter of the Follower gear. Then set the LayerToFollow, in the Expression, to the name of the Leader gear.
Set the Ratio in the expression to the size of the Leader, relative to the Follower.

LayerToFollow = "Leader";
Ratio = 3/4
mul((this_comp.layer(LayerToFollow).rotation) * Ratio, -1)
