Abstract
Abstract Driving and driven members of a drive train are arranged as plates astraddle a flange with springs arranged between the plates to engage the flange for resisting angular displacement between the plates and the flange. Elastomeric annuli are compressed between the plates and the faces of the flange with sufficient force to maintain a nonslip engagement with these parts as viscoelastic deformation of the annuli dampens the smaller of the angular displacement. The compressive force on the annuli is insufficient to prevent slipping of the annuli for larger angular displacements to prevent destruction of the annuli.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
In a coupling between a driving and a driven member including a flange extending radially from one of said members, a pair of spaced-apart plates extending the other of said members astraddle said flange, and a plurality of springs arranged between said plates to engage said flange for resisting angular displacement between said flange and said plates, a damper assembly comprising: a. at least one of said plates and said flange having smooth, confronting surfaces throughout an annular concentric region; b. a flat, smooth, elastomeric annulus arranged between said confronting surfaces with freedom to assume any angular relationship with said confronting surfaces; c. said plates being secured together to compress said annulus between said confronting surfaces with sufficient force to hold said annulus in nonslip engagement with said confronting surfaces as viscoelastic deformation of said annulus dampens angular displacements between said flange and said plates; and d. said compression of said annulus being insufficient to prevent angular slipping of said annulus to a new angular relationship with said confronting surfaces for occasional angular displacements between said flange and said plates larger than said vibrational displacements.
Claim 2
Dependent Claim
185 words
In a coupling between a driving and a driven member including a flange extending radially from one of said members, a pair of spaced-apart plates extending the other of said members astraddle said flange, and a plurality of springs arranged between said plates to engage said flange for resisting angular displacement between said flange and said plates, a damper assembly comprising: a. at least one of said plates and said flange having smooth, confronting surfaces throughout an annular concentric region; b. a flat, smooth, elastomeric annulus arranged between said confronting surfaces with freedom to assume any angular relationship with said confronting surfaces; c. said plates being secured together to compress said annulus between said confronting surfaces with sufficient force to hold said annulus in nonslip engagement with said confronting surfaces as viscoelastic deformation of said annulus dampens angular displacements between said flange and said plates; and d. said compression of said annulus being insufficient to prevent angular slipping of said annulus to a new angular relationship with said confronting surfaces for occasional angular displacements between said flange and said plates larger than said vibrational displacements.
