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 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.
Flexible element:
1. Natural rubber block bonded to.
2. V-shaped metal armatures.
Flange: aluminium or cast-iron.
3. Drive segment.
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.
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.
