A Better Way to Protect Generator Bearings

Nov 27, 2009· The bearing protection ring and collar were on the drive end of the shaft, and the standard carbon block brushes were on the non-drive end. For the Series 2 readings, the bearing protection ring was disengaged and the shaft collar removed, leaving the carbon block brushes on the non-drive-end as the only shaft-current mitigation path. A closer look

How to prevent false brinelling in rolling-element bearings

Jan 20, 2015· Changes to the pitch are infrequent and small, leading to damage to the bearings supporting the blade. Intentional motion can be imposed on the system to promote lubricant flow. This motion is called dither. The minimum motion required is a function of the spacing of rolling elements within the bearing.
