![]() ![]() Finally, Figure 1, DETAIL C uses a worm wheel and a hyperbolic worm gear which provides the greatest amount of surface area. The second is to have a worm wheel as shown in Figure 1, DETAIL B in this case, the receiving gear has a concave outer ring in order to increase surface contact. The first can be simplified down to two cylinders perpendicular to each other as seen in Figure 1, DETAIL A. In a gear, the surface strength, shear force and bending stress of the gear tooth majorly contribute to the failure of the gears. There are many styles and methods to create worm gears I will elaborate on three. Helical gears are chosen for gearbox design as they are extensively used in industrial operations for power transmission under heavy loads with smoother and noiseless operation. Since SOLIDWORKS Toolbox does not contain any worm gears, I needed to create my own. The benefit of the worm gear is it allows me to convert the motion from the motor to the gears in a compact way, with an added benefit is that it looks fantastic. That presented an opportunity to apply some unique solutions. ![]() I decided to use a worm gear since I needed to have the motor perpendicular to the gearing to help minimize the profile of this project. If you missed Part 1 and 2, you will find the links at the bottom of this post. Today’s blog article is focused on creating a worm gear. Thank you for returning to my Kinetic art project series.
