Start with a polygon 12-16 sides
Shape tool, drag a node towards center to make a star looking thing
Shape tool click down from point tip to create node now grab points node move it Down to make point a square
Create a circle hold shift and control to make it evenly round, place it over the other object make sure it intersects each tooth on the polygon
Group those together make another circle smaller for the center of gear, trim that
Now do an interactive fill across it to shade
Use the extrude tool to give dimension
And BOOM its a gear
Simple as mud
