Title (EN) ROLLING BEARING ARRANGEMENT AND WIND TURBINE
(FR) ENSEMBLE PALIER À ROULEMENT ET ÉOLIENNE
(DE) WÄLZLAGERANORDNUNG UND WINDKRAFTANLAGE
Abstract:
(EN) The invention relates to a rolling bearing arrangement (1) for a wind turbine (10), comprising an outer ring (2) and an inner ring (3) mounted inside the outer ring (2), at least in part. The outer ring (2) and the inner ring (3) are rotatable about an axis of rotation (4) relative to one another. Between the outer ring (2) and the inner ring (3), a first tapered roller bearing (5) having first tapered rollers (6) and a second tapered roller bearing (7) having second tapered rollers (8) is arranged. The invention is characterized in that in the unloaded state of the rolling bearing arrangement (1), the first tapered rollers (6) have a first logarithmic roller profile, and the second tapered rollers (8) have a second logarithmic roller profile that differs from the first logarithmic roller profile. The invention further relates to a wind turbine (10) having the rolling bearing arrangement (1).
(FR) L'invention concerne un ensemble palier à roulement (1) pour une éolienne (10), comprenant une bague extérieure (2) et une bague intérieure (3) montée au moins partiellement à l'intérieur de la bague extérieure (2), la bague extérieure (2) et la bague intérieure (3) pouvant tourner l'une par rapport à l'autre autour d'un axe de rotation (4), un premier roulement à rouleaux coniques (5) pourvu de premiers rouleaux coniques (6) et un deuxième roulement à rouleaux coniques (7) pourvu de deuxièmes rouleaux coniques (8) étant placés entre la bague extérieure (2) et la bague intérieure (3). L'invention est caractérisée en ce que, à l'état non sollicité de l’ensemble palier à roulement (1), les premiers rouleaux coniques (6) présentent un premier profil logarithmique et les deuxièmes rouleaux coniques (8) présentent un deuxième profil logarithmique qui diffère du premier profil logarithmique. L'invention concerne en outre une éolienne (10) comprenant l'ensemble palier à roulement (1).
(DE) Es wird eine Wälzlageranordnung (1) für eine Windkraftanlage (10) aufweisend einen Außenring (2) und einen zumindest teilweise innerhalb des Außenrings (2) gelagerten Innenring (3) vorgeschlagen, wobei der Außenring (2) und der Innenring (3) um eine Drehachse (4) relativ zueinander drehbar sind, wobei zwischen dem Außenring (2) und dem Innenring (3) ein erstes Kegelrollenlager (5) mit ersten Kegelrollen (6) und ein zweites Kegelrollenlager (7) mit zweiten Kegelrollen (8) angeordnet ist, dadurch gekennzeichnet, dass im unbelasteten Zustand der Wälzlageranordnung (1) die ersten Kegelrollen (6) ein erstes logarithmisches Rollenprofil und die zweiten Kegelrollen (8) ein von dem ersten logarithmischen Rollenprofil abweichendes zweites logarithmisches Rollenprofil aufweisen. Ferner wird eine die Wälzlageranordnung (1) aufweisende Windkraftanlage (10) vorgeschlagen.
