Abstract
Abstract The flexible coupling includes an elongated sleeve with a plurality of radially extending elongated blades and a cylindrical elongated hub with a plurality of radially outwardly extending blades. The sleeve is coaxially positioned on the hub member with the sleeve inwardly extending blades alternately interleaved between the outwardly extending blades of the hub member. Elongate flexible members having metal plates bonded to their sidewalls are positioned between the interleaved blade members. Sleeve channel members are positioned around the axial ends of the sleeve blade members at one end of the hub in abutting relation with the adjacent ends of the metal plates secured to the flexible members. An annular plate member is secured to a flanged end portion of the sleeve to maintain the elastic members axially between the blades. Hub channel members are positioned around the axial ends of the hub blade members at the opposite end of the hub and also in abutting relation with the adjacent ends of the metal plates secured to the flexible members. With the above arrangement the sleeve channel members and hub channel members abut opposite sides of the flexible members at opposite ends thereof. A retaining ring is secured to the hub in abutting relation with the hub channel members and an end ring is secured to an opposite flanged portion of the sleeve member in abutting relation with a thrust ring which is secured to the retaining ring. The dimensions of the sleeve member, the hub member, the channel members and the flexible members with the metal plates secured thereto are such that an axial force exerted on the end ring preloads the flexible members axially. Substantial axial thrust can be imposed on the preloaded coupling without axial movement between the components of the coupling. Above a given predetermined axial thrust, axial movement between the components takes place. Torsional preloading of the flexible members is accomplished by wedging them into the spaces between the interleaved blades which are circumferentially smaller than the width of the flexible members in their free state.

Claim 1
Independent Claim
132 words
In a flexible coupling having a driving element and a driven element, the combination comprising: said driving element having spaced projecting blades with opposite end portions; said driven element having spaced projecting blades with opposite end portions; said blades on said driven element projecting alternately between the blades on said driving element forming an interleaved relation therebetween; flexible elements positioned between said interleaved projecting blades and having sidewalls and end walls, said sidewalls abutting the adjacent sidewalls of said interleaved projecting blades and forming a flexible connection between said interleaved projecting blades; and retaining means abutting certain of said blade end walls and said flexible member end portions to maintain said flexible elements between said interleaved blades and distort said flexible elements axially to maintain an axial thrust on said flexible elements.
Claim 2
Dependent Claim
132 words
In a flexible coupling having a driving element and a driven element, the combination comprising: said driving element having spaced projecting blades with opposite end portions; said driven element having spaced projecting blades with opposite end portions; said blades on said driven element projecting alternately between the blades on said driving element forming an interleaved relation therebetween; flexible elements positioned between said interleaved projecting blades and having sidewalls and end walls, said sidewalls abutting the adjacent sidewalls of said interleaved projecting blades and forming a flexible connection between said interleaved projecting blades; and retaining means abutting certain of said blade end walls and said flexible member end portions to maintain said flexible elements between said interleaved blades and distort said flexible elements axially to maintain an axial thrust on said flexible elements.
Claim 3
Dependent Claim
55 words
A flexible coupling as set forth in claim 1 which includes second rEtaining means secured to the top surface of certain of said projecting blades on one of said elements in overlying relation with portions of said flexible elements on opposite sides of said projecting blades to maintain said flexible elements between said interleaved blades.
Claim 4
Dependent Claim
52 words
A flexible coupling as set forth in claim 2 which includes rigid sidewalls on both sides of said flexible elements, said rigid sidewalls abutting the adjacent sidewalls of said projecting blades so that each of said projecting blades abuts a pair of rigid sidewalls of said flexible elements on opposite sides thereof.
Claim 5
Dependent Claim
21 words
A flexible coupling as set forth in claim 1 in which said flexible elements have concave bottom, top and end walls.
Claim 6
Dependent Claim
150 words
A flexible coupling comprising: a hub member having blades projecting radially outwardly therefrom; a sleeve member having spaced blades projecting radially inwardly therefrom; said sleeve member positioned coaxially on said hub member with said inwardly projecting blades positioned alternately between said hub member outwardly projecting blades and forming an interleaved relation therebetween; flexible elements positioned between said interleaved projecting blades, said flexible elements having rigid sidewalls abutting the adjacent sidewalls of said interleaved projecting blades; first retaining means abutting said flexible element rigid sidewalls on opposite sides of said hub member blades adjacent one end of said sleeve member; second retaining means abutting said flexible element rigid sidewalls on opposite sides of said sleeve member blades adjacent the other end of said sleeve member; and thrust means exerting an axial thrust on said retaining means and distorting said flexible element and provide a preload axial thrust on said flexible elements.
Claim 7
Dependent Claim
150 words
A flexible coupling comprising: a hub member having blades projecting radially outwardly therefrom; a sleeve member having spaced blades projecting radially inwardly therefrom; said sleeve member positioned coaxially on said hub member with said inwardly projecting blades positioned alternately between said hub member outwardly projecting blades and forming an interleaved relation therebetween; flexible elements positioned between said interleaved projecting blades, said flexible elements having rigid sidewalls abutting the adjacent sidewalls of said interleaved projecting blades; first retaining means abutting said flexible element rigid sidewalls on opposite sides of said hub member blades adjacent one end of said sleeve member; second retaining means abutting said flexible element rigid sidewalls on opposite sides of said sleeve member blades adjacent the other end of said sleeve member; and thrust means exerting an axial thrust on said retaining means and distorting said flexible element and provide a preload axial thrust on said flexible elements.
