A set of meshing gears

thingiverse

These are a set of precision-engineered gears, each featuring robust, useful torque capabilities. A 9-tooth pinion with a 1/4" flattened hub is designed to fit snugly onto an aluminum hub made from sturdy 1/4" round stock. By drilling the aluminum to match the motor shaft and adding a secure set screw, you can lock this gear in place with confidence. The other gears are equally impressive: a 27-tooth input idler, a 30 x 15-tooth compound gear, and a 30-tooth output gear with a 1/4" square socket for effortless locking to an output shaft. These high-performance gears boast a diameter of about 1-3/4" and are built with durable teeth that can withstand demanding applications. I manufacture these gears using PLA, a material prized for its exceptional hardness and rigidity. This ensures that my gears remain precise and reliable even under heavy use. How I Design My Gears To bring these innovative designs to life, I employ a gear generator program that allows me to input specific gear properties. Once the parameters are set, the software exports the gear drawing as a 2D DXF file, which I then import into AutoCad for final fine-tuning. From there, I export the revised design to 3D Design, where I create a detailed 3D model complete with accurate thickness, hubs, and other critical features. The resulting G-Code is then used by my printer to produce precise, high-quality gears that meet the most exacting standards. It's a streamlined process that makes it easy to create complex gear systems with confidence.
