Abstract

Vorgeschlagen ist ein Rollenelement (1a, 1 b) für ein schwenkbewegliches Maschinenteil (2), das vorzugsweise als Schwenkhebel (12a, 12b) eines hubvariablen Ventiltriebs einer Brennkraftmaschine ausgebildet ist. Das Rollenelement ist auf einem mit dem Maschinenteil verbundenen Rollenbolzen (3) gleit- oder wälzgelagert angeordnet und weist eine in dessen axialer Richtung gestufte Außenmantelfläche (6) mit benachbarten und im Durchmesser voneinander verschiedenen Axialabschnitten (7a, 8a, 9a, 7b, 8b, 9b) auf, zwischen denen jeweils eine Ringstirnfläche (10a, 11 a, 10b, 11 b) verläuft, wobei das Maschinenteil über wenigstens einen der Axialabschnitte in radialer Richtung des Rollenelements abgestützt und über die eine oder mehrere Ringstirnflächen in axialer Richtung des Rollenelements geführt ist. Dabei soll das Rollenelement in sich starr ausgebildet sein.
