Abstract
A coupling has an inner member and an outer annular member and an intermediate annular member which when aligned share a common axis and have a common centre on the common axis. The inner and the intermediate annular member are constrained to rotate, one with respect to the other about a second axis perpendicular to the common axis. The intermediate annular member and the outer annular member are constrained to rotate, one with respect to the other about a third axis perpendicular to the common axis and the second axis. The members are spaced apart to leave a gap between each of the members.
Claims7
A coupling comprising:
- an inner member, an outer annular member and an intermediate annular member between the inner member and the outer annular member which, when aligned, share a common axis and have a common centre on the common axis;
- the inner member comprising a central aperture in which a shaft is engaged;
- one or a diametrically opposed pair of first axles disposed radially of the common centre coupling the inner member and the intermediate annular member, and constraining the inner member and the intermediate annular member to rotate, one with respect to the other about a second axis perpendicular to the common axis;
- one or a diametrically opposed pair of second axles disposed radially of the common centre coupling the outer annular member and the intermediate annular member, and constraining the outer member and the intermediate annular member to rotate, one with respect to the other about a second axis perpendicular to both the common axis and the first axis;
- the inner member, intermediate annular and outer annular member being spaced apart with a gap between each of the members and in that the gaps and the concentricity of the intermediate annular member is maintained by the axles being fixed in the one or other of the inner or outer annular member and intermediate annular member and supported in bearings in the other, and wherein
- said coupling is one of two such couplings in which the shaft links the central apertures of the inner members of the couplings, with a drive shaft connected to the outer member of one coupling and a driven shaft connected to the outer member of the other coupling.

- the inner member, intermediate annular and outer annular member being spaced apart with a gap between each of the members and in that the gaps and the concentricity of the intermediate annular member is maintained by the axles being fixed in the one or other of the inner or outer annular member and intermediate annular member and supported in bearings in the other of the inner or outer member and intermediate member;
- a pulse damper disposed are around the central axis, said pulse damper comprising a first end plate and a second end plate said end plates being parallel and opposed to one another;
- the first end plate being connected an input or output;
- the second end plate being connected to the outer annular member;
- one of the said end plates comprising an axle centred on the central axis extending therefrom towards the other of said end plates which has a tube extending therefrom around said axle and co-axial with said axle and forming a housing for a plurality of bearings between the co-axial tube and the axle;
- a damping ring comprising an even number of dividers disposed equidistantly from one another around said co-axial tube, the dividers comprising elastomeric material between them, with alternate dividers being fixed to the first end plate from which the axle extends, the other dividers being fixed to the co-axial tube.
