Roller or silent chain couplings have sprockets on each shaft coupled by a chain or chains. They are useful for heavy-duty, high torque applications. Steel grids have slotted flanges on each shaft ...

Most rigid couplings are made of aluminum, steel, or stainless steel. Bore diameter is the internal diameter for mating to the shaft-end. Coupling diameter is the outside diameter (OD), a measurement ...

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 ...
