On the Lubricating Mechanism of Roller Skew in Cylindrical Roller Bearings
Tribology Transactions, 2013Skewing is the motion of a roller as it turns about an axis normal to the roller–race interface in cylindrical roller bearings. With a special coordinate transformation technique, complete numerical solutions for the finite line elastohydrodynamic lubrication (EHL) contact formed between a roller and races were obtained to investigate the lubricating ...

On the Causes and Effects of Roller Skewing in Cylindrical Roller Bearings
Tribology Transactions, 1998Cylindrical roller bearings which support thrust and/or moment loading in addition to predominant radial loading have flanges on both the inner and outer rings to accommodate the thrust loading carried by the rollers. The roller thrust loading causes roller tilting and friction moments about the rotating axis perpendicular to both the bearing and ...

Cage Instabilities in Cylindrical Roller Bearings
Journal of Tribology, 2004A six-degree-of-freedom model was developed and used to simulate the motion of all elements in a cylindrical roller bearing. Cage instability has been studied as a function of the roller-race and roller-cage pocket clearances for light-load and high-speed conditions.
