Elliptical Gears

This 3D-printed elliptical gearbox is designed to demonstrate how non-circular gears can convert constant rotational input into variable rotational speed. The model features two elliptical gears mounted on a sturdy base, making it a great educational tool or conversation piece for gear enthusiasts and makers alike.When you rotate one gear, the other responds with variable speed due to the changing radii of the elliptical shapes. This principle is useful in applications where variable output speed is required, such as certain pumps, textile machinery, and specialized robotics mechanisms.
