The torsionally flexible jaw coupling ZS-DKM-SH is a double-cardanic elastomer coupling with split hubs (SH SPLIT).
The ROTEX ZS-DKM-SH with SPLIT hub provides the advantage that the coupling can be radially assembled and disassembled without displacing the adjacent power packs. The hub resp. connection of the two hub halves is not weakened by cracking.
This design is also referred to as drop-our center design coupling, half shell coupling, clamping coupling, coupling with split hubs or elastomer coupling with split clamping hub.
The hubs of the double-cardanic jaw coupling ROTEX ZS-DKM-SH are mechanically split by cracking and screwed back together with the assembly. This elastomer coupling is ideally suitable to offset larger radial displacements. Due to the split hubs the coupling can be radially assembled and disassembled without displacing the adjacent power packs.
