Abrégé
(DE) Die Erfindung betrifft ein Großwälzlager, insbesondere mittenfreies Großwälzlager, mit zwei konzentrischen Laufringen, zwischen denen in einem Lagerspalt eine Vielzahl von Wälzkörpern vorgesehen sind, die auf zumindest zwei Laufbahnen abwälzen. Insbesondere ist der Lagerspalt zwischen den Laufringen und/oder zwischen zumindest einem Laufring und den Wälzkörpern zumindest teilweise mit einem Festkörperschmierstoff, der eine Polymermatrix und einen darin eingebetteten Schmierstoff umfasst, befüllt.
(EN) The invention relates to a large rolling bearing, more particularly an open-center large rolling bearing, comprising two concentric running rings, between which a plurality of rolling elements is provided in a bearing gap, which rolling elements roll on at least two raceways. More particularly, the bearing gap between the running rings and/or between at least one running ring and the rolling elements is at least partially filled with a solid lubricant, which comprises a polymer matrix and a lubricant embedded therein.
(FR) L'invention concerne un palier à roulement de grande dimension, en particulier un palier à roulement de grande dimension à centre libre, comportant deux bagues de roulement concentriques entre lesquelles, dans un intervalle de roulement, un pluralité d'éléments roulants roulent sur au moins deux chemins de roulement. En particulier, l'espace entre les bagues de roulement et/ou entre au moins une bague de roulement et les éléments roulants est au moins partiellement rempli d'un lubrifiant solide comprenant une matrice polymère et un lubrifiant intégré dans celle-ci.
