Cast Iron: A Solid choice for Reducing Gear Noise - September/October 1999
The article "Cast Iron: A Solid choice for Reducing Gear Noise" appeared in the September/October 1999 issue of Gear Technology.
Material selection can play an important role in the constant battle to reduce gear noise. Specifying tighter dimensional tolerances or redesigning the gear are the most common approaches design engineers take to minimize noise, but either approach can add cost to the finished part and strain the relationship between the machine shop and the end user. A third, but often overlooked, alternative is to use a material that has high noise damping capabilities. One such material is cast iron.
