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 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.
