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 ...

With gear or multi-jaw couplings, gears with external teeth are mounted on shafts. A sleeve with internal teeth fits over the gears. These couplings provide high torque and allow axial misalignment, ...

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

After testing several kinds of gear teeth, gear diameters ... We think it would be helpful to revise the drive shaft coupling method, allowing the handle or drill to be easily removed from ...
