Title (EN) IMPROVED BEARING ASSEMBLY
(FR) ENSEMBLE DE PALIER PERFECTIONNÉ
Abstract:
(EN) An improved bearing assembly is disclosed. Ring-shaped rolling elements in an alternating staggered formation, which allows maintenance of the bearing assembly geometry with fewer structural elements than prior bearings. The rolling elements can create a constant elastic tension, or preload, which maintains the bearing assembly geometry under various loads and rotational speeds, and reduces wear on the rolling elements and the raceways. The rolling elements can also comprise energy-dampening members and/or instrumentation which can monitor the functioning of the bearing assembly. An alternate embodiment in which the rolling elements are interlocked allows the use of more rolling elements in the same volume. An improved cage assembly, highly suitable for use with the improved bearing assembly, is also disclosed. The improved cage assembly comprises individual cage segments, which each retain one rolling element. The cage assembly can flex at every joint in a way not allowed by prior cage assemblies.
(FR) L'invention concerne un ensemble de palier perfectionné. L'invention concerne des éléments roulants en forme d'anneau dans une formation en quinconce alternée, qui permettent la maintenance de la géométrie d'ensemble de palier avec moins d'éléments structurels que les paliers précédents. Les éléments roulants peuvent créer une tension élastique constante, ou une précharge, qui maintient la géométrie de l'ensemble de palier sous diverses charges et vitesses de rotation, et réduit l'usure sur les éléments roulants et les chemins de roulement. Les éléments roulants peuvent également comprendre des éléments d'amortissement d'énergie et/ou des instruments qui peuvent surveiller le fonctionnement de l'ensemble de palier. Un autre mode de réalisation dans lequel les éléments roulants sont verrouillés permet d'utiliser davantage d'éléments roulants dans le même volume. L'invention concerne également un ensemble de cage perfectionné, hautement approprié pour une utilisation avec l'ensemble de palier perfectionné. L'ensemble de cage perfectionné comprend des segments de cage individuels, qui retiennent chacun un élément roulant. L'ensemble de cage peut fléchir au niveau de chaque articulation d'une manière qui n'est pas permise par les ensembles de cage antérieurs.
