Ratchet and Pawl system.

myminifactory

I designed a custom ratchet and pawl system for my university project, adapting it for 3D printing capabilities. This unique design allows the ratchet to turn in one direction only. To assemble the system: insert the shaft into the central hole of the base, position the keyway within the notch at the end of the shaft, then place the ratchet onto the assembly as shown in the image. Next, attach the pawl to the bolt and secure it in the upper base hole with the large bolt facing forward. Finally, tighten the nut to allow the pawl to rotate freely. The right-hand side notch on the base is intended for attaching a spring, which will be connected to the pawl at the other end. Gravity should sufficiently load the mechanism, making it functional without the need for an additional spring.
