Potential of oil-lubricated cylindrical plastic gears
Bending strength of injection molded polyacetal test gears is investigated in back-to-back testing using oil-lubrication. To validate state of the art calculation methods, tooth geometries with a variable number of teeth are investigated, maintaining a ...

Observations of acoustic emission activity during gear defect diagnosis. [PDF]
It is widely recognised that acoustic emission (AE) is gaining ground as a non- destructive technique (NDT) for health diagnosis on rotating machinery.

Influence of Variable Side-Stay Geometry on the Shimmy Dynamics of an Aircraft Dual-Wheel Main Landing Gear [PDF]
Commercial aircraft are designed to fly but also need to operate safely and efficiently as vehicles on the ground. During taxiing, take-off, and landing the landing gear must operate reliably over a wide range of forward velocities and vertical loads ...

Friction behavior in a sliding contact is strongly influenced by the surface topography of the bodies in contact. This also applies to friction clutches. Even small differences in surface topography may cause significant differences in friction behavior.

Identification and Validation of Linear Friction Models Using ANOVA and Stepwise Regression
For wet disk clutches, the energy input is strongly influenced by its friction behavior. However, the friction behavior cannot be simulated and therefore is mostly derived from experimental data for specific clutch systems.

Bearing Power Losses with Water-Containing Gear Fluids
Lubricants have a large influence on gearbox power losses. Recent investigations at a gear efficiency test rig have shown the high potential of water-containing gear fluids in drastically reducing load-dependent gear losses and temperatures.

CFD Analysis on the Heat Dissipation of a Dry-Lubricated Gear Stage
Power losses in gearboxes result in frictional heating. Sufficient heat transfer from the gearbox to the environment is required for reliable operation. The heat dissipation from gears is linked to their interaction with fluids in the gearbox.
