Abstract
A coupling between a driving and a driven shaft includes a rigid tube to which are attached by bonding, in axially spaced apart relation at least two flexible annular elements of elastomeric material, the annular elements being of various shapes; the outer periphery of each ring is bonded to an attachment ring which is attachable to a flange of a connecting hub with each hub mounted or connected to one the shafts; in one form the tube is split axially and is adjustably attachable to the periphery of the rings.
Claims37
A coupling apparatus for connecting two shafts for rotational transmission of torque between the shafts, comprising a spool having an axis and having opposite, axially spaced ends and an exterior surface, a pair of flexible, annular elements each mounted on said spool in axially spaced apart relation adjacent a respective said end, at least one of said annular elements having an radially inner base having an inner peripheral surface adhesively bonded to said exterior surface of said spool, said at least one of said annular elements extending from said base thereof along a substantially arcuate path to a radially outer periphery, said outer periphery being attached to a ring member which surrounds the axis of said spool, at least one of said annular elements being made of an elastomeric material.
A coupling apparatus for connecting two shafts for rotational transmission of torque between the shafts, comprising a spool, a pair of flexible annular elements each mounted directly on said spool in axially spaced apart relation, a pair of hubs with one of said pair of hubs being attachable to one shaft and the other of said pair of hubs being attachable to the other of said shafts, each hub having a flange portion and at least two connecting members on each flange portion for connecting the respective flange to one of said annular elements, said annular elements each being made from an elastomer material, wherein each said annular element has an inner peripheral edge, each said inner peripheral edge being mounted on and adhesively bonded to the exterior surface of a hub element.
A coupling apparatus for connecting two shafts for rotational transmission of torque between the shafts, comprising a spool, a pair of hubs each for mounting on one of the shafts, each hub having an outer peripheral surface and a flexible ring mounted on said outer peripheral surface, each flexible ring having an outer peripheral edge connected to a reinforcing ring, said spool having opposite ends, each said end being connected to a said reinforcing ring.
A coupling apparatus for connecting two shafts for rotational transmission of torque between the shafts, comprising a spool having a cylindrical surface and is free of any flanges, a pair of flexible rings each having an inner surface mounted directly on said cylindrical surface of said spool in axially spaced apart relation, a pair of hubs with one of said pair of hubs being attachable to one shaft and the other of said pair of hubs being attachable to the other of said shafts, each hub having a flange portion and at least two connecting members on each flange portion for connecting the respective flange to one of said flexible rings, said flexible rings each being made from an elastomer material, each said flexible ring extending from said base thereof along a substantially arcuate path to a radially outer periphery.
A coupling apparatus for connecting two shafts for rotational transmission of torque between the shafts comprising a spool having a cylindrical surface and a pair of flexible annular members each having an inner surface adhesively bonded directly onto said cylindrical surface of said spool in axially spaced apart relation, each said flexible member having an outer periphery adhesively bonded to a reinforcing ring, each said reinforcing ring having attachment means for attaching a said ring to a shaft, said annular members being made from an elastomer material.
