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 ...

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 ...

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.
