Numerical investigation of the air–oil two-phase flow inside an oil-jet lubricated ball bearing

International Journal of Heat and Mass Transfer, 2014
Abstract The air–oil two-phase flow inside an oil-jet lubricated ball bearing was investigated by the CFD method. The VOF method for multiphase flow was used to track the air–oil two-phase flow. The sliding mesh plane was applied between the flow field inside the bearing and the flow field on both outsides of the bearing. The results suggest that the

A new formulation for convective heat transfer in oil jet lubricated spur gears

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology
This study aims to analyze thermal heat-transfer between an oil jet and a rotating spur gear using a novel experimental methodology 1 to have an analytical model based on lubrication conditions and geometric characteristics of spur gears.

Volume of Fluid (VOF) Analysis of Oil-Jet Lubrication for High-Speed Spur Gears Using an Adaptive Meshing Approach

Volume 7A: Structures and Dynamics, 2015
In high speed gearbox systems, the lubrication is generally provided using nozzles to create small oil jets that feed oil into the meshing zone. It is essential that the gear teeth are properly lubricated and that enough oil gets into the tooth spaces to permit sufficient cooling and prevent gearbox failure.

A novel approach for identifying gas cavitation in oil jet pumps for lubrication systems:

2019
Curkovne črpalke za olje so ključna komponenta mazalnih sistemov turbostrojev. S povečevanjem gostote moči pri turbostrojih se pojavlja problem kavitacije v omenjenih črpalkah, ki lahko ogroža varnost obratovanja. Med različnimi vrstami kavitacije v curkovnih črpalkah za olje ima posebno vlogo plinska kavitacija, ki znatno vpliva na učinkovitost ...

Criterion representation of power loss in the hybrid bearing with oil-jet lubrication

2017
В работе предложена аналитическая зависимость с применением критериев подобия для определения потерь мощности при вращении шарикоподшипника. Новизна данного представления в том, что оно учитывает расход масла, это позволяет более точно оценить составляющую потерь, приходящуюся на перемешивание масла.
