Ball Ratchet
grabcad
In the second phase of constructing a miniature, 3D-printed gear ratchet for a spring-powered vehicle, I created upper and lower sections of the outer gear that snap together, featuring an inner spline-driven ratchet. Version 3 exhibited low rolling resistance but was extremely difficult to assemble. It could function with three bearings instead of six, although performance was acceptable. Previously, Version 2 worked well, albeit noisy and tough to reverse ratchet. However, it boasted impressive locking strength.
