Ratchet - Educational model

My Educational Mechanical Examples SeriesThis model is one of my educational mechanical mechanism examples on 80mm x 80mm base plates.You can find all models of the series in this collection => [Mechanical Mechanism Examples]This modelThis is an educational model of a spring-free ratchet mechanism which does not cause large click noise when it freewheels. Turning the central disc clockwise drives the outer ring, while turning it counterclockwise makes the ratchet freewheel. Brief descriptionGenerally speaking, a ratchet mechanism is used to allow rotation in only one direction, preventing reverse motion. In this model, the ratchet works between two rotational elements: the central disk acts as the input, and the outer ring serves as the output.When the input disk is rotated clockwise, the ratchet prevents relative motion between the two parts. As a result, the output ring rotates together with the input. On the other hand, when the input is
