Gear Hardness and Hardness Testing Gears are designed to operate under several known circumstances and from those circumstances designers can understand how strong a gear must be to operate properly. During the manufacture of different gears, the gear or gear blank cannot be cut in its final hardness due to machine or cost efficiency constraints.…
Threads Threads can be generated by means of subtractive, formative or additive manufacturing methods, though the most common method for precision thread generation is by subtractive methods such as thread cutting or grinding. Different methods are used for internal and external threads being generated. Threads are used in assembly applications for various engineering systems, as…
Worm and Worm Wheels Worm gear sets are comprised of a worm and a worm wheel, or worm gear. These gear sets transmit power between two non-parallel, non-intersecting shafts, generally have an angle of 90 degrees between them. A worm is essentially a thread wrapped around a shaft while a worm gear is a gear…
