dc.description.abstractThe choice of which lubrication strategy to apply for pump bearings has implications for both the short term characteristics exhibited by the bearings and their long term reliability. When lubricating rolling element bearings, four basic strategies have historically been employed: Grease lubrication; Oil bath lubrication; Oil lubrication via slinger disc or oil ring; Oil mist lubrication. For high speed (3000 RPM and higher), slinger discs or oil rings are commonly used due to the short re-greasing interval exhibited with grease lubrication and the high heat generation due to churning seen with oil bath lubrication. This paper seeks to reprise the work of Lemmon & Booser, Heshmat & Pinkus, Gardner and Ettles et al in defining the equations of performance related to oil slinger discs and oil rings. It will then address some of the operational and reliability concerns of each of these oiling methods using a purpose built test rig that is representative of the current state of the art in bearing housing design for pumps. Specifically it will look at how the following parameters affect oil delivery and stability: Rotational speed; Bearing housing inclination; Oil ring material; Slinger geometry; Slinger and oil ring submergence depth.en
