Flexible coupling for torque-transmitting connection of two elements, and assembly

Abstract

A flexible coupling for torque-transmitting connection of two elements comprising a supporting body to which are assigned pick-up fixtures which are movably disposed relative to one another, to each pick-up fixture there is assigned at least one elastically deformable layer. Each pick-up fixture surrounds one at least partly spherically shaped elastic layer and a cylindrically shaped elastic layer, and wherein the layers cooperate during the relative movement of the pick-up fixtures. Such a flexible coupling finds use in an assembly.

Claims

1. A flexible coupling for torque-transmitting connection of two elements, comprising: a supporting body; anda plurality of pick-up fixtures disposed within said supporting body that are disposed movably relative to one another, each pick-up fixture including at least one elastically deformable layer,wherein each pick-up fixture surrounds one at least partly spherically shaped elastic layer and a cylindrically shaped layer, the partly spherically shaped elastic layer and the cylindrically shaped layer cooperating during relative movement of the pick-up fixtures.

2. The flexible coupling as defined in claim 1, wherein each pick-up fixture surrounds one cylindrical sleeve and one at least partly spherically shaped sleeve.

3. The flexible coupling as defined in claim 2, wherein the cylindrical sleeve is surrounded by the cylindrical elastic layer, the cylindrical elastic layer being surrounded by the at least partly spherically shaped sleeve and the sleeve being surrounded by the at least partly spherically shaped layer.

4. The flexible coupling as defined in claim 2, wherein the at least partly spherically shaped sleeve is surrounded by the at least partly spherically shaped layer, the at least partly spherically shaped layer being surrounded by the cylindrical sleeve and the sleeve being surrounded by the cylindrical elastic layer.

5. The flexible coupling as defined in claim 1, wherein the at least partly spherically shaped elastic layers are provided with flattened regions.

6. The flexible coupling as defined in claim 1, wherein the supporting body is spherically shaped in at least some regions.

7. The flexible coupling as defined in claim 1, wherein recesses are provided in at least an outer periphery of the supporting body.

8. The flexible coupling as defined in claim 1, further comprising a centering sleeve disposed in the supporting body for accepting an end of a shaft.

9. The flexible coupling as defined in claim 8, wherein the centering sleeve is provided with an elastic layer.

10. An assembly comprising a flexible coupling according to claim 1, wherein the flexible coupling includes a first side and a second side, the first and second sides having at least one flange, each flange is assigned an end of a shaft, and each flange being connected with at least one pick-up fixture.

11. A flexible coupling comprising: a support body supporting a first flange and a second flange; anda plurality of pick-up fixtures disposed between said first flange and said second flange, each pick-up fixture including a cylindrical sleeve, a cylindrically shaped elastic layer, an at least partly spherically shaped sleeve, and an at least partly spherically shaped elastic layer,wherein said cylindrically shaped elastic layer yields to a greater extent than said partly spherically shaped elastic layer during movement of said pick-up fixtures.

12. The flexible coupling of claim 11, wherein said pick-up fixtures move cardanically and axially.

13. The flexible coupling of claim 11, wherein said first flange and said second flanges each include a plurality of arms, said pick-up fixtures disposed between said arms of said first flange and said second flange.

14. The flexible coupling of claim 11, wherein said at least partly spherically shaped elastic layer includes flat regions.

15. The flexible coupling of claim 11, wherein said supporting body includes at least one recess.
