Powder metal gears are found in aerospace, agricultural, automotive, building and construction, marine transportation, material handling, medical, military, petrochemical, pharmaceutical, power generation and robotics industries. The demand for application specific metal gears has led to the introduction of several types or styles such as anti-backlash, bevel, miter, chance, cluster, differential, helical, herringbone, hypoid, internal, planetary, spur and pinion gears. While these mechanisms can be produced in a number of machining processes, powder metal parts provide several advantages over traditional gear manufacturing methods.
