... solved by Liang’s method decreases. To resolve these two issues of low time consumption and good accuracy under vital hydrodynamic lubrication, this study suggests a new approach that treats the circumferential bearing lands on both sides of recesses as infinitely long bearings and treats the axial...

... in the literature. Ma et al. [ 15 ] developed a model to study the hydrodynamic lubrication in cylindrical REB cage pockets. The authors used the Reynolds equation to determine the pressure inside the cage pocket and friction from fluid shear. It was assumed that the pocket was fully flooded and lubricant...

... enter the hydrodynamic lubrication faster in the acceleration phase. In the deceleration phase, slow deceleration helps the journal-bearing system maintain hydrodynamic lubrication for a longer time. The higher final speed, lower lubrication oil temperature, and lower bearing clearance can make...
