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 Precompressed natural rubber.
2 Bonded metal reinforcing mountings.
3 Precompression band (to be removed after installation).
Flange:
4 Die-cast steel (except 632267 which is cast-iron).
Flexible element 1: polyurethane in the form of a Maltese cross.
Flange 2: cast iron with drive segments 3 supplied unbored (except633054 and 633055).
Variations : For assemblies with a ring or spacer, consult our technical manuals.
