A track Gear differential: The self-locking differential gear via 3D printing process

A open source project allows 3D printing of a self-locking differential gear previously used in high quality vehicles. The completed differential illustrates the basic principle of force distribution. If one downforce is braked, the other may continue to rotate. This function is particularly important when driving in curves, since the wheels arehave to rotate at different speeds. That >>A track gear differential<< can be replicated with basic CAD knowledge.

The self-locking differential gear differs from a conventional bevel gear differential in its design of spur gears. It consists of two sun gears and six planetary gears, which are arranged in opposite directions. A drive bevel gear transfers the force to the differential basket. The peculiarity ofDesigns are in its simple design. All parts are based on basic geometric shapes and can be reproduced without complex CAD knowledge. The planetary gears distribute the load evenly and ensure smooth operation. The assembly is step by step. First, the large drive bevel gear is attached to the differential basket. After that, the planet gearsused, followed by the sun gears and their spacers. Clip connections secure the assembly in the frame.
