Experimental results indicate that oil supply can have a significant effect on cage and roller motion in a lubricated roller bearing. A theoretical analysis is presented which enables cage and roller motion, for various operating conditions, to be predicted. The theoretical results imply that reducing the oil supply to a minimum value required to maintain full hydrodynamic conditions, reduces cage slip by up to 75 percent of its fully flooded value. This conclusion is consistent with existing experimental evidence.
This paper describes the development of an empirical equation used to determine the minimum thrust load that is required to prevent gross ball and cage skidding in high speed angular contact bearings. Based on extensive computer results the equation is shown to give excellent agreement with existing experimental evidence.
This paper describes the start of an investigation into the factors affecting cage and roller slip in high-speed roller bearings. Cage and roller speeds, for different radial clearances, are measured over a range of steady radial loads and shaft speeds, using several lubricants. These results are analysed and compared with existing theoretical evidence. To improve the correlation between theory and practice further theoretical results of cage and roller motion are obtained for bearing conditions relevant to the regime where the fluid pro-perties are pressure dependent. The theoretical extent of cage and roller slip shows only a fair agreement with the experimental findings. However, the load below which cage slip will occur is much more accurately forecast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
