Если это правда ENTER_FRAME, то по идее

//ЕнтерФрейм
private function eFrame(e:Event) {
   var angle:Number;
   angle=Math.atan2(mouseY+291,mouseX)*180/Math.PI;
   if(angle - logo.gear.rotation > 180)
      angle -= 360;//ищем кратчайший поворот
   if(logo.gear.rotation - angle > 180)
      angle += 360;//ищем кратчайший поворот
   TweenLite.to(logo.gear, 0.5, {rotation:angle, overwrite:1});
   bigGear.rotation = -logo.gear.rotation*0.5;
   gearNG.rotation = -logo.gear.rotation*2;
   gearLvl.rotation = -logo.gear.rotation*2;
   gearHS.rotation = -logo.gear.rotation*2;
}
