Skidding research of a high-speed cylindrical roller bearing with beveled cage pockets

Abstract: Purpose This study aims to uncover the influencing mechanism of the tilt angles of the cage pocket walls of the high-speed cylindrical roller bearing on the bearing skidding. Design/methodology/approach A novel cylindrical roller bearing with the beveled cage pockets was proposed. Using the Hertz contact theory and the elastohydrodynamic and hydrodynamic lubrication formulas, the contact models of the bearing were built. Using the multibody kinematics and the Newton–Euler dynamics theory, a dynamics model of… Show more

“…[20] can be targeted to the skidding ratio analysis of a specific rolling element. Liu [21] and Tu [6] conducted research on the cylindrical roller bearing vibration responses as skidding occurs, and discussed the effects of frictional force [11,13] and cage pocket type. The results indicate that a proper cage pocket size (tilt angles of 5° and 10° for the front and rear walls can attenuate the skidding degree, and the skidding-induced friction forces are www.Springer.com/journal/40544 | Friction strongly related to the vibration level.…”

“…Relevant data show that the contact area lubrication failure is caused by the bearing and is the main reason for wear and failure. A good lubrication state is maintained as an effective measure to reduce wear and avoid failure of rolling bearings [3][4][5][6][7][8][9]. In the lubrication process, the oil film is heated by viscous shear and compression, resulting in an increase in temperature, causing the oil film thickness and pressure to change.…”
