Flexible element comprising:
1 Natural rubber in the form of a cross.
2 A floating aluminium or steel star, whose arms are bonded to the rubber.
Mountings:
Two aluminium bosses, bonded to the rubber which will be attached to one of the machines.
Two bosses bonded to the rubber which will be attached to the other machine.
The TETRAFLEX coupling is designed with the following features:
– Binary symmetry which allows considerable conical misalignment.
– The rubber is precompressed from manufacture which limits operation under tension.
Advantages:
The floating star allows:
– Increased torque capacity without reducing the axial flexibility, hence reduced size for a given torque.
– Rotation at higher speeds as the star ensures that the arms are anchored centrifugally.
– A good torque/speed ratio.
Flexible element made up of a variable number of FLEXIBLE STUDS
1 depending on the torque to be transmitted:
2 Solid natural rubber blocks in the form of a truncated cone.
3 Internal armature bonded to the rubber.
4 Threaded stud.
5 External armature bonded to the rubber.
6 Studding welded to armature.
7 Cylindrical metal cover.
Steel disks:

5 Band for precompressing the rubber before assembly.
Two retaining bars are supplied although not shown in the photo.
Flexible element comprising a variable number of flexible bushes, depending on the torque to be transmitted.
1 Inner with tapped or smooth holes (normal mounting or on fly wheel).
2 Precompressed natural rubber bonded to inner 1 and to outer the half-cylinders 3.
3 Half-cylinders bonded to the rubber.
4 Outer housing ensuring precompression of rubber by exerting pressure on the half-cylinders 3.
Steel disks:
5 Flange to which the inner studs are attached (normal mounting).
6 Disk to which the studs are attached (flywheel mounting).
Die cast steel hubs:
7 The two hubs are identical. They may be bolted to disks 5 or 6 depending on the mounting used.
