Vibration damper for absorbing rotary vibrations in a camshaft or crankshaft has a flywheel and a running wheel to rotate on bearings and roll away on a surface

摘要

A flywheel's (7) center of gravity (S) describes a course that is an epicycloid or a hypocycloid (Z). A flywheel support (3) constitutes a first running wheel (FRW) fitted radially on a camshaft or crankshaft to rotate on bearings with a first bearing surface (3a). The FRW rolls away on a surface (4) fitted coaxially to an axis (2a) of rotation.
