Engineers and manufacturers often speak of “gear quality.” In the U.S. the term is usually associated with a quality number based on AGMA criteria – this number is by no means a comprehensive ...

Gear tooth geometry is determined primarily by pitch, depth, and pressure angle. Pitch: Standard pitches are usually whole numbers when measured as diametral pitch P, the ratio of the number of teeth ...

Simulation tools are now available to simulate complex gear measurements after heat-treatment simulation. This is the focus of the feature article that has just been published in Thermal Processing, ...

Hypoidal ring and pinion gears are the most efficient way to transfer rotational power at right angles, from a vehicle’s engine to its wheels. These gears, having curved, angled teeth, were conceived ...
