“Heat treatment is a critical and complex element in the manufacturing of gears [and] greatly impacts how each will perform in transmitting power or carrying motion to other components in an assembly. Heat treatments optimize the performance and extend the life of gears in service by altering their chemical, metallurgical, and physical properties.” (Bugiliarello, et…
Grinding is the most common form of abrasive machining processes. It “is a material removal process accomplished by abrasive particles that are contained in a bonded graining wheel rotating at very high surface speeds.” The tool used in grinding is called the wheel and “consists of abrasive particles and bonding material. The bonding material holds…
Contact ratio is average number of gear teeth in contact with one another as the gears are in operation. Gear tooth profiles must be dimensioned in such a way that more than one pair of gears must be in contact with one another. This insures smooth and quiet operation of the gear pair. The formula…
