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).
In addition to the characteristics described above, the separate hub used in conjunction with the STRAFLEX coupling provides the advantage: ready to assemble without machining.
Advantages:
– Reduced size.
– Simplified axial positionning.
– Easy to assemble and disassemble.
– Reduction of costs by simplifying the machining required for the shafts and flanges.
Recommendation:
The reinforced textile structure means that it has a low tolerance to irregularities in the torque.
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 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).
Flexible element comprising:
1 Natural rubber in the form of a cross.
2 A floating aluminium star, whose arms are bonded to the rubber.
Mountings:
3 Two aluminium bosses, bonded to the rubber, which will be attached to one of the machines.
4 Two aluminium bosses, bonded to the rubber, which will be attached to the other machine.
5 Band for precompressing the rubber before assembly.
Two retaining bars are supplied although not shown in the photo.
