GearTrax is an intuitive and easy to use tool for creating solid models of gear and drive components. GearTrax creates models of spur and helical gears, bevel gears, worm gears, involute splines, timing belt pulleys, chain sprockets, V-belt pulleys, and even creates spur gear geometry for use in adding gear teeth to existing SolidWorks models. Easy to use for a designer with limited gear design experience yet powerful enough for experts is gear design to rely on model accuracy; the product develops accurate SolidWorks models in literally seconds. An animation window shows the spur/helical gear mesh and updates as the data is changed helps the user understand how changes to the gear parameters will be reflected on the gear mesh.
