Lubrication and its role in gear-failure analysis
When gears fail, it is most often due to fatigue and overloading. The most common form of distress and failure […]
Multi-sensor metrology advances
Demand for accurate gears delivered on tight schedules is increasing. To keep pace, technology is continually advancing, enabling manufacturers to […]
Finding the ideal materials for gears
When designing an individual gear or a gear train, the choice of material will either be the primary factor on […]
Nonlinear dynamic characteristic analysis of a coated gear transmission system
Coatings can significantly improve the load-carrying performance of a gear surface, but how they affect the vibration characteristic of the […]
Optimization of rack and pinion for offshore jack-up applications
Liftboats or jack-up oil rigs are essential for the oil and gas industry. The subsystem (rack, pinion, gearbox, and brake) […]
Root cause for noise excitation in geometrically-accurate (perfect) parallel-axes gearing
Gears are extensively used to transmit a rotation from a driving shaft to a driven shaft. Depending on the gear […]
