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 ...

Beam, flexured or helical couplings prevent backlash and provide constant velocity with angular misalignment. With gear or multi-jaw couplings, gears with external teeth are mounted on shafts. A ...

Gearboxes and gearheads, also called gear reducers or speed reducers ... Input and output connection configurations for gearboxes and gearheads include solid shaft, hollow shaft and integral coupling.
