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).

The separate hub used in conjunction with the JUBOFLEX coupling provides the advantage :

Ready to assemble without machining the flanges.

Advantages

➤ Reduced size.

➤Simplified axial positionning.

➤Easy to assemble and disassemble.

➤ Reduction of costs by simplifiying the machining required for the shafts and flanges.

Recommendation

In use, precompression is achieved by the fixing bolts and the JUBOFLEX coupling operates

without the precompression band round the flexible element.

ASSEMBLY

➤ Precompression for the initial installation is achieved by a band  placed round the outside (our

flexible elements are delivered with this band).

➤Position the flexible element with its band to attach three non-adjacent holes to the three arms of

one flange, and then the three other holes to the other flange.

➤Tighten the bolts to the following torques :

Cut the original band or remove the disassembly band.
