Abstract
A resilient shaft coupling includes a annular member constructed of a hexagonal resilient joint disc and at least one attaching element which includes a plurality of flange arms. The resilient joint disc includes attaching regions at its corners provided with axial connecting element bores. The straight sides of the joint disc are provided with thin web regions which permit elastic deformation.
Claims16
A resilient shaft coupling comprising:
- a fiber reinforced resilient annular member comprising a joint disc with web regions and connecting regions, circumferentially alternating around said annular member;
- at least one homogenous attaching element for connecting a shaft to the circumference of said annular member, the at least one attaching element having a plurality of integral flange arms;
- and wherein said resilient annular member is formed into the flange arms of the attaching element so as to fully enclose the connecting regions of the joint disc at the flange arms.
A resilient shaft coupling comprising:
- a fiber reinforced resilient annular member comprising a joint disc with web regions and connecting regions, circumferentially alternating around said annular member;
- at least one unitary attaching element for connecting a shaft to the circumference of said annular member, the at least one attaching element having a plurality of flange arms;
- wherein said resilient annular member is formed into the flange arms of the attaching element so as to fully enclose the connecting regions of the joint disc;
- wherein the disc joint is polygonous and the joint disc and flange arm are connected at the corner points;
- and
- a plurality of axial webs connected to the flange arms respectively, said axial webs disposed radially inside the resilient joint disc and tapering radially outward.
A method of producing a resilient shaft coupling including a resilient joint disc and attaching element comprising:
- providing a resilient joint disc;
- and
- molding a homogenous attaching element having a plurality of flange arms so that said flange arms completely surround at least a portion of said joint disc.
A resilient shaft coupling comprising:
- a fiber reinforced resilient annular member comprising a joint disc with web regions and connecting regions, circumferentially alternating around said annular member;
- at least one homogenous attaching element for connecting a shaft to the circumference of said annular member, said at least one attaching element having a plurality of flange arms integrally formed with said homogenous unitary attaching element;
- wherein said resilient annular member is molded into the flange arms of the attaching element during the molding of the attaching element so as to capture the annular member within said flange arm.
