Abstract
Abstract A damper ring for damping vibration of a structural member. The damper ring includes an annular recess for receiving an extension, such as a flange, of the structural member and can include radially extending tabs to restrict relative axial movement. The damper ring is preferably severed to allow it to be retained radially against the extension of the structural member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
69 words
Means effective for damping vibration of an annular structural member including a neutral axis and an annular extension protruding only radially from said structural member, comprising a damper ring having a neutral axis and only a radially facing, annular recess therein for receiving said extension, and thereby mounting said damper ring on said structural member for radially spacing said neutral axes of said structural member and said damper ring.
Claim 2
Dependent Claim
69 words
Means effective for damping vibration of an annular structural member including a neutral axis and an annular extension protruding only radially from said structural member, comprising a damper ring having a neutral axis and only a radially facing, annular recess therein for receiving said extension, and thereby mounting said damper ring on said structural member for radially spacing said neutral axes of said structural member and said damper ring.
Claim 3
Dependent Claim
12 words
The damping means of claim 1 wherein said extension comprises a flange.
Claim 4
Dependent Claim
17 words
The damping means of claim 1, wherein said damper ring is of a generally U-shaped cross section.
Claim 5
Dependent Claim
19 words
The damping means of claim 1, wherein said damper ring is severed for enabling diametral expansion and contraction thereof.
Claim 6
Dependent Claim
12 words
The damping means of claim 1, wherein said damper ring is metallic.
Claim 7
Dependent Claim
29 words
The damping means of claim 2, wherein said damper ring further comprises means for restricting relative axial movement between said damper ring and said flange of said structural member.
Claim 8
Dependent Claim
33 words
The damping means of claim 6, wherein said means for restricting relative axial movement comprises at least one tab extending radially from said damper ring and adjacent said flange of said structural member.
Claim 9
Dependent Claim
106 words
Means effective for damping vibration of an annular structural member including a neutral axis and an annular flange extending only radially from said structural member, comprising a metallic damper ring severed for enabling diametral expansion and contraction thereof, said damper ring having a neutral axis and only a radially facing, annular recess therein for receiving said flange and thereby mounting said damper ring on said structural member for radially spacing said netural axes of said structural member and said damper ring, and having a plurality of tabs extending radially therefrom and adjacent said flange for restricting relative axial movement between said damper ring and said flange.
Claim 10
Dependent Claim
106 words
Means effective for damping vibration of an annular structural member including a neutral axis and an annular flange extending only radially from said structural member, comprising a metallic damper ring severed for enabling diametral expansion and contraction thereof, said damper ring having a neutral axis and only a radially facing, annular recess therein for receiving said flange and thereby mounting said damper ring on said structural member for radially spacing said netural axes of said structural member and said damper ring, and having a plurality of tabs extending radially therefrom and adjacent said flange for restricting relative axial movement between said damper ring and said flange.
Claim 11
Dependent Claim
17 words
The damping means of claim 8, wherein said damper ring is of a generally U-shaped cross section.
Claim 12
Dependent Claim
160 words
Means effective for damping vibration of a rotatable, annular structural member including a neutral axis and an annular flange extending radially inwardly from said structural member, comprising a metallic damper ring severed for enabling diametral expansion and contraction thereof, having a neutral axis and only a radially outwardly facing, annular recess therein for receiving said flange and thereby mounting said damper ring on said rotatable structural member for radially spacing said neutral axes of said structural member and said damper ring, said damper ring having a U-shaped cross section defined by a base portion and sidewalls, and having a plurality of tabs extending radially outwardly from each of said sidewalls and adjacent said flange for restricting relative axial movement between said damper ring and said flange, and said damper ring being disposed radially inward of said flange and dimensioned for enabling centrifugal force to exert a radial force on said damper ring for retaining said damper ring on said flange.
Claim 13
Dependent Claim
160 words
Means effective for damping vibration of a rotatable, annular structural member including a neutral axis and an annular flange extending radially inwardly from said structural member, comprising a metallic damper ring severed for enabling diametral expansion and contraction thereof, having a neutral axis and only a radially outwardly facing, annular recess therein for receiving said flange and thereby mounting said damper ring on said rotatable structural member for radially spacing said neutral axes of said structural member and said damper ring, said damper ring having a U-shaped cross section defined by a base portion and sidewalls, and having a plurality of tabs extending radially outwardly from each of said sidewalls and adjacent said flange for restricting relative axial movement between said damper ring and said flange, and said damper ring being disposed radially inward of said flange and dimensioned for enabling centrifugal force to exert a radial force on said damper ring for retaining said damper ring on said flange.
Claim 14
Dependent Claim
56 words
