About this document
Girth Gear Failure Analysis in Ball Mill by Jaime Gutierrez is a document available to read on EtoBox.
- The document describes a failure analysis of cracks in the girth gear of an industrial ball mill. - 3D finite element modeling analyzed stresses from charge weight, charge motion, centrifugal forces, and pinion driving forces. It found charge weight and motion caused most stress, with pinion contributing only 20%. - Stresses matched crack characteristics and were highest in specific locations by the gear flange, indicating this is where cracks initiated. - Crack growth rates were modeled and compared to
