摘要:
La présente invention concerne un rotor arrière de giravion comportant au moins deux éléments de pale (1), chaque élément de pale (1) étant apte à pivoter autour d'un axe Z de variation d'un pas collectif pour faire varier ledit pas collectif de chaque élément de pale dudit rotor arrière, chaque élément de pale (1) comportant au moins une masse de compensation (2) comportant une protubérance (4) émergeant sensiblement perpendiculairement à un axe principal d'inertie (5) dudit élément de pale (1), ledit axe principal d'inertie (5) étant parallèle à une direction longitudinale de l'élément de pale. Conformément à l'invention, le rotor se caractérise en ce que la masse de compensation (2) comporte une portion déformable (6), mobile par rapport à la protubérance (4) dans un plan P parallèle à l'axe principal d'inertie (5) de l'élément de pale (1).

摘要:
A damper unit for a lift, for the purpose of reducing vertical vibration of a stopping lift car (2), has at least one roller (5, 6, 7) which, in an active position, is in contact with the guide rail (3) and can be rotated about an axis of rotation (R). For the purpose of damping the rotary movements during vertical vibration of the stopping lift car (2), the roller (5, 6, 7) is connected to a rotation damper (8, 9, 10).
