Effects of deformations and angular ring misalignment on
In this paper, a comprehensive model of ball bearing considering deformations and angular ring misalignment is proposed to investigate the bearing dynamic properties. The geometrical interactions between the assembly state and the bearing deformations are derived based on the deformation coordination conditions. …

Soft measurement of ball mill load under variable working …
In actual industrial production, labeled sample data of a ball mill is difficult to obtain under variable working conditions. Aiming to realize the soft measurement of ball mill load under variable working conditions, a joint discriminative high-order moment alignment network (JDMAN) is proposed, based on the deep transfer learning in this paper.

What Happens When a Pinion Bearing Goes Bad?
Identifying a Failing Ball Mill Pinion Bearing Unusual Noises. One of the primary indicators of a failing pinion bearing is the emergence of unusual noises during the operation of the ball mill. Listen for grinding, knocking, or rumbling sounds, as these may suggest that the bearing is experiencing excessive friction or misalignment.

Self-Aligning Bearings | SpringerLink
The outer raceway of this bearing is a portion of a sphere. Thus balls on the inner raceways are internally aligned with respect to the outer raceway to accommodate any misalignment, free from any moment loads. Unlike conventional ball bearings, the outer raceway in the self-aligning ball bearings does not conform well to the balls.
