Abstract
A coupling means (10) extending along a longitudinal axis of symmetry (100) from a first plate (11) towards a second plate (12), which plates are connected together by a link member (20). Said link member (20) is provided with a first hub (21) secured to said first plate (11) and with a second hub (22) secured to said second plate (12), a first end section (21′) of the first hub (21) being connected to a second end section (22′) of the second hub (22) by link means (30), said link means (30) comprising a first web (31) connecting said first end section (21′) to a maximum section (33) of said link means (30), said link means (30) having a second web (32) connecting a second end section (22′) of said second hub (22) to said maximum section (33).
Claims20
A one-piece coupling means comprising:
- a first plate extending along a longitudinal axis of symmetry towards a second plate;
- the first plate and the second plate being connected together by a hollow link member defining an inside space;
- wherein the link member is provided with a first hub secured to the first plate and a second hub secured to the second plate, a first end section of the first hub being connected to a second end section of the second hub by link means;
- the link means comprising a first frustoconical web connecting the first end section to a maximum section of the link means, the link means having a second frustoconical web connecting the second end section of the second hub to the maximum section;
- and
- the maximum section being the portion of the link member that is transversely furthest away from the longitudinal axis of symmetry.
A rotable coupling member for coupling rotable shafts, the rotable member comprising:
- a first plate extending orthogonally to a longitudinal axis of symmetry, the first plate having a plurality of radially spaced fastener holes;
- a second plate extending orthogonally to the longitudinal axis of symmetry and spaced from the first plate, the second plate having a second plurality of radially spaced fastener holes;
- the first plate and the second plate being connected together by a hollow link member defining an inside space;
- wherein the link member is provided with a first hub secured to the first plate and a second hub secured to the second plate, a first end section of the first hub being connected to a second end section of the second hub by a web link comprising a first frustoconical web connecting the first end section to a maximum section of the link and a second frustoconical web connecting the second end section of the second hub to the maximum section;
- and
- the maximum section being the portion of the link member that is transversely furthest away from the longitudinal axis of symmetry.
A one-piece coupling comprising:
- a first plate extending orthogonally to a longitudinal axis of rotational symmetry;
- a second plate extending orthogonally to the longitudinal axis of rotational symmetry spaced from the first plate;
- a hollow link member connecting the first plate and the second plate together, the hollow link member defining an inside space, the hollow link member having a first hub secured to the first plate and a second hub secured to the second plate, the first hub having a first end section and the second end having a second end section;
- and
- a web link connecting the first end section of the first hub to the second end section of the second hub, the web link comprising a first frustoconical web, a second frustoconical web, and a maximum section connecting the first web to the second web, the maximum section being the portion of the web link that is transversely furthest away from the longitudinal axis of rotational symmetry.
