Influence of the Shape of a Rolling Body on the Hydro-Dynamic Power Losses in High-Speed Antifriction Bearings,

Abstract

An experimental study was made of the power losses incurred in driving the rolling elements of gas turbine ball bearings. An attempt was made to ascertain whether results obtained regarding the estimation of power losses due to overcoming hydrodynamic resistance forces in roller bearings can be used in calculations of the energy losses incurred in driving gas turbine ball bearings. It is shown that in the absence of an axial load an estimate of the power required to drive turbine ball bearings can be made by a method proposed by one of the authors for high speed roller bearings.
