F16H GEARING
Description
F16H covers mechanical power transmission systems that transmit motion and torque between rotating shafts through direct contact of teeth, friction surfaces, or flexible elements. This subclass encompasses gear types including spur gears, helical gears, bevel gears, worm gears, and rack-and-pinion systems, as well as non-toothed alternatives such as friction wheels and belt/chain drives. The classification includes gear design, manufacture, lubrication, efficiency optimization, and integrated transmission assemblies across applications ranging from automotive and industrial machinery to household appliances. Related noise reduction, vibration damping, and gear material specifications are covered within this subclass.
