Numerical investigation of the oil–air distribution inside ball bearings with under-race lubrication
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021Oil distribution inside the under-race lubricated bearing is crucial for lubrication and cooling of high-speed ball bearings. An under-race lubricated ball bearing is modeled to numerically investigate the effects of operating parameters and feed hole configuration on the distribution behavior of lubricant oil.

The Numerical Study of Oil Drop Jet from Oil-Air Lubrication Nozzle
Advanced Materials Research, 2011Nozzle is an important part of oil-air lubrication system. This paper uses Computational Fluid Dynamics (CFD) software FLUENT to study the flow field of oil air, and different air pressure and nozzle throat size are discussed. The results show that: When air pressure is increased from 0.05Mpa to 0.1Mpa, the maximum diameter (2mm) percentage reduces ...

Investigation of the ball-bearing temperature rise under an oil-air lubrication system
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2001Ball-bearings are widely used on many high-speed rotating systems. However, heat generation and dynamic loading caused by high-speed operation have been the limiting factors for increasing the speed limit of many high-speed ball-bearing applications. Therefore, providing proper lubrication and preload to reduce heat generation effectively is a major ...
