Flexible element:
1 Formed of solid natural rubber.
2 External steel surround, bonded to the rubber.
3 Triangular hub: a hollow hub bonded to the rubber and attached to the flange 5, or a solid hub which accommodates a grooved or keyed shaft.
Steel flanges:
4 round.
5 triangular.
The CARDAFLEX coupling is designed with the following features:
– Safe in use.
– Fairly low conical stiffness.
– Compact shape.
– Good performance at high speeds.
Advantages:
– Especially in the case of the CARDAFLEX solid hub coupling, the space occupied by the unit is much reduced.
– The outer surround of the flexible element can be centred directly on-to the flywheel of one of the machines to be coupled.
Flexible element:
1 Metallic bobbins linked together by rayon fibres.
2 The whole unit 1 is potted in natural rubber and is hexagonal.
Flange:
3 Forged steel specially bored to accommodate the separate hub.
4 Universal separate hub (not supplied by PAULSTRA).
Flexible element:
1 Six fairly hard natural rubber shaped support blocks, on the inside edge of the outer ring of the coupling.
Flange:
2 inside flange has six arms which fit axially between the blocks by “blind axial” assembly.
Outer ring:
3 Ring with teeth that hold the blocks.
Standard SAE fixing and centring.
Flexible element:
1. Natural rubber block bonded to.
2. V-shaped metal armatures.
Flange: aluminium or cast-iron.
3. Drive segment.
Flexible element:
1 Precompressed natural rubber
2 Bonded metal spacers,
3 Precompression band (to be removed after installation).
Flange:
4 Die-cast steel (except 632320 which is cast-iron).
