SELF-CONTAINED GREASE LUBRICATION SYSTEMS FOR AIRCRAFT APPLICATIONS

The need for add-on, self-sufficient systems, together with simplified existing helicopter components that are lighter in weight and require less maintenance, create an effort directed toward ingenious concepts. This paper directs attention toward one such add-on, an infrared suppressor and its self-contained bearing/grease lubrication system. Against the requirements for self-contained lubrication systems in helicopter and aircraft bearing support applications, the design principles and concepts, development, and demonstration of grease cavities for antifriction bearings are described.
