Latest Patents
One of her latest patents is titled "Rolling element bearing having starved lubrication conditions." This invention involves a rolling element bearing that consists of an inner ring and an outer ring, each equipped with a raceway. The design includes a series of rolling elements that maintain contact with the raceways of both rings. A lubricant film is established in the contacts between the rolling elements and the raceways, forming a lubricant meniscus at the inlet side of each contact. In this bearing, starved lubrication conditions are prevalent. The surface of each rolling element features minute recesses filled with a lubricant quantity. These recesses are flattened in the contact area, allowing lubricant to be released at the inlet side of each contact. This results in a displacement of the meniscus further away from the contact, leading to an increased lubricant film thickness in each contact area. Consequently, this innovation improves the lubricating conditions within the bearing.
Career Highlights
Marie-Laure Dumont is currently employed at SKF Engineering and Research Centre B.V., where she continues to develop her expertise in bearing technology. Her work has been instrumental in advancing the understanding of lubrication in rolling element bearings.
