The objective of optimized shaft alignment is to increase the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate ...

Torque is a stone-cold killer. While its more flamboyant partner, Horsepower, rakes in the magazine headlines and dyno-chart hosannas, Torque wages a quiet but unceasing campaign of mechanical mayhem ...

Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between the rotor and stator, and transfer loads from the shaft to the motor frame.

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 ...
