Roller for a pendulum mass of a centrifugal force pendulum

摘要

The vibration damper for damping vibrations for rotation around an axis of rotation, including a first component with at least one bow spring channel formed radially outside of a second component. A spring is formed in the bow spring channel, and fixed by a counter-component, wherein the first and second component and counter-component are made of sheet metal, characterized in that the second component and at least one of the following contact components: a) the first component and b) the counter-component have common contact areas, into which the second component and the at least one contact component run vertically to the rotation axis, and in which the edges thereof for centering lie one against the other, at least in some sections.

1. A vibration damper for damping vibrations and for rotation about an axis of rotation, the vibration damper comprising:
a first component having at least one bow spring channel formed radially outside of a second component, at least one spring being formed in the at least one bow spring channel, the spring being fixed in the bow spring channel by a counter-member, the first component and the second component and the counter-member being made of sheet metal, the second component and at least one contact component, wherein the at least one contact component is at least one of: a) the first component and b) the counter-member having common contact areas, the second component and the at least one contact component running perpendicularly to the axis of rotation in common contact areas, and in the common contact areas, edges the second component and at least one contact component having edges that at least partially abut each other for centering purposes; wherein at least one bearing area is formed, the second component and at least one of: a) the first component and b) the counter-member abutting each other flat in the at least one bearing area; and wherein, in at least one first bearing area of the at least one bearing area, the counter-member abuts against a first side of the second component in the direction of the axis of rotation and, in at least one second bearing area of the at least one bearing area, the first component abuts against a second side of the second component situated opposite the first side.
