Rigid couplings are for well-constrained systems where the two shafts are not likely to get out of perfect axial alignment. Rigid couplings include sleeve or muff couplings which generally clamp ...

Interfacing a shaft to a 3D printed gear doesn’t have to be tricky. [Tlalexander] demonstrated a solution that uses one half of a spider coupling (or jaw coupling) to create an effective modular ...
