Experimental Investigation on Roller Skewing and Tilting at the Loaded Positions of Double-Row Tapered Roller Bearings Under Eccentric Loading Available to Purchase

Eccentric loading is a widespread issue in the engineering field that can notably affect the performance of double-row tapered roller bearings (DTRBs). Eccentric loading can trigger roller skewing and tilting, resulting in localized temperature spikes and a shortened lifespan of the bearing. In this study, an experimental system was transformed to apply eccentric radial loads and detect roller movements based on the established methodologies. The effects of combined conditions including eccentric radial load, axial load, shaft speed, and bearing temperature on these roller movements were investigated experimentally. The results indicate that the roller skew angle reaches its minimum value, while the tilt angle exhibits an inverse trend at the most loaded position of the bearing. Furthermore, both the roller skew angle and the tilt angle increase with the eccentric displacement, axial load, and shaft speed, but decrease with the increasing radial load and bearing temperature.
