When an important gear failure occurs, someone becomes responsible for analyzing the failure, determining its cause and recommending a solution. A company can select its own engineer, an outside consultant or both. If a consultant is called in, this should be done as early in the process as possible. Though similar procedures apply to any failure analysis, the specific approach can vary depending
Michael Sexton's ball mill Michael Sexton sent me some pictures of the ball mill that he built using wooden gears drawn with the gear template generator. Michael writes: "This design has turned out rather well. Those are steel bearings in the center of each gear. They are held in by a press fit (forstner bit with a bit of tape around the bearing). They hold up to wear pretty well. I have had ...

A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or ...
