Development of High-Hardness-Cast Gears for High-Power Mining Applications - January/February 2017

The article "Development of High-Hardness-Cast Gears for High-Power Mining Applications" appeared in the January/February 2017 issue of Gear Technology.

Summary
Multiple possibilities are available to increase the transmissible power of girth gears. These solutions include: using a larger module, increasing of the gear diameter through the number of teeth, enlarging the face width, and increasing the hardness of the base material. The first three parameters are mostly limited by cutting machine capability. Module, outside diameter, and face width (for a cast gear) can theoretically be increased to infinity, but not the cutting machine dimensions. There are also practical limits with respect to the installation of very large diameter/large face width gears.
