Leeds-Lyon Symposium on Tribology 'The Tribology Design of Machine Elements' (15th) 6-9 September 1988.

摘要

The industrial definition of tribology tends to be somewhat wider than the classical 'study of friction and wear'. The interest of the industrial tribologist will extend beyond the behaviour of the contact itself to consider heat generation, cooling, component stressing and life. In the case of the aero engine the most prominent tribological problem is bearings. The combination of load, speed and environment have caused the designer to use tool steels to meet the required life. A less obvious tribological application is that of the rubbing blade tip seals on compressors where any excessive wear directly affects the engine performance. Gearboxes are common to both helicopters and turbo-prop engines. The applications are very different due to the very high ratio required for a helicopter and the different safety requirements since, in the case of the helicopter, the gear box is fundamental to its operation.
