Vibration damping coupling

A coupling for transmitting torque between at least a pair of rotatable members, one of said members having a polygonal peripheral surface portion, the other of said members having a polygonal peripheral surface portion, a coupling element comprised of a plurality of sections of trapezoidal cross section corresponding in number to the sides of said surface portions disposed in side by side abutting relation, each section having a surface portion confronting and engageable with said peripheral surface portions and each section consisting of metal and elastomer layers.

A coupling for transmitting torque between at least a pair of rotatable members, one of said members having an interior polygonal peripheral surface portion, the other of said members having an exterior polygonal peripheral surface portion, a coupling element comprised of a plurality of sections of trapezoidal cross section corresponding in number to the sides of said surface portions disposed in side by side abutting relation, each section having a surface portion confronting and engageable with said interior and exterior peripheral surface portions and each section consisting of metal and elastomer layers.

A coupling for transmitting torque between a series of coaxially oriented shaft members, adjacent shaft members in said series each having terminal end portions with an exterior polygonal peripheral surface portion, a sleeve element circumscribing said terminal end portions having an internal polygonal surface portion confronting and radially spaced from said exterior polygonal surface portions of said adjacent shaft members and a coupling element comprised of a plurality of trapezoidally shaped sections corresponding in number to the sides of said surface portions disposed in the space between said sleeve member and terminal end portions of adjacent shafts, said sections disposed in side by side abutting relation and engageable with said interior and exterior peripheral surface portions, each section consisting of metal and elastomer layers.

A coupling for transmitting torque comprising inner and outer sleeve members having confronting exterior and interior polygonal peripheral surfaces and a coupling element comprised of a plurality of sections of trapezoidal cross section corresponding in number to the sides of said surface portions disposed in side by side abutting relation, each section having a surface portion confronting and engageable with said interior and exterior peripheral surface portions and each section consisting of metal and elastomer layers.

A coupling for transmitting torque between at least a pair of rotatable members, one of said members having a polygonal exterior peripheral surface portion, the other of said members having a polygonal interior peripheral surface portion, a coupling element comprised of a plurality of sections of trapezoidal cross section corresponding in number to the sides of said surface portions disposed in side by side abutting relation, each section having a surface portion confronting and engageable with said peripheral surface portions and each section consisting of metal and elastomer layers, the angularly disposed sides of adjacent sections being in abutting relation and the parallel inner and outer faces of said sections abutting the interior and exterior peripheral surface portions of said members.
