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 ...
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 ...
Even before the Industrial Revolution, gears of one kind or another have been put to work both for and against us. From ancient water wheels and windmills that ground grain and pounded flax, to the ...
Army invests in technology that typically makes clocks work to increase helicopter transmission powe
The U.S. Army Research Laboratory (ARL) helped figure out 20 years ago a revolutionary way to increase transmission power in the Apache helicopter without increasing the transmission's size or weight.
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 ...
Q: What are the challenges when machining gears for wind turbines? Gears for wind turbine applications are typically large in diameter and have wide face widths, requiring very exacting material ...
GWJ Technology GmbH from Braunschweig, Germany, one of significant suppliers of calculation software for gears and gearboxes, has announced a new version for its GearEngineer software. Herringbone ...
