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.
The STRAFLEX coupling is designed with the following features:
– Radial disassembly without moving the machines that are coupled.
– Reduced size.
– Used at relatively high rotational speeds.
Recommendation:
The reinforced textile structure means that it has a low tolerance to irregularities in the torque.
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.
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:
1 Precompressed natural rubber.
2 Bonded metal spacers.
3 Precompression band (to be removed after installation).
Flange:
4 Die-cast steel specially bored to fit the separate hub.
5 Universal separate hub (not supplied by PAULSTRA).
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:
8 Two identical disks, bolted to the flanges 10 and with slits 9 to house the studs 1.
Flanges: 10 die-cast steel.
