Gearboxes can fail in drastically different ways Data: 257 gearbox damaged records Bearings: 70%; gears: 26%; and others: 4% Observations: • Both bearing and gear failures are concentrated in the parallel section • Top failure mode is high-speed shaft (HSS) or intermediate-speed shaft (IMS) bearing axial cracks Damage
The larger the mill, the greater are the stresses between the shells and heads and the trunnions and heads. In the early 1970s, maintenance problems related to the application of gear and pinion and large speed reducer drives on dry grinding cement mills of long length drove operators to
Gear failure often follows bearing failure. Gear tooth contact patterns. (Complete this step before disassembling gearbox components for inspection). The way in which mating gear teeth contact indicates how well they are aligned (Figure 1). If practical, record tooth contact patterns under either loaded or unloaded conditions.
