ROTEX COUPLING KTR ZS-DKM-H

DESCRIPTION: Double-cardanic drop-out center design coupling - radial assembly/disassembly The torsionally flexible jaw coupling ZS-DKM-H is a double-cardanic elastome coupling with split hubs (half shell coupling). This type is also referred to as drop-out 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-H are split. 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.

Torsionally flexible jaw coupling ZS-DKM-H

Double-cardanic drop-out center design coupling - radial assembly/disassembly

The torsionally flexible jaw coupling ZS-DKM-H is a double-cardanic elastome coupling with split hubs (half shell coupling).
This type is also referred to as drop-out 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-H are split. 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.

Benefits of couplings with split hubs Rotex ZS-DKM-H

Please find more detailed information about benefits of half shell couplings in our article "Couplings with split hubs: benefits and applications".

Double-cardanic jaw coupling for large shaft displacements
Good damping properties due to double arrangement of spiders
Spacers adjusted to drop-out center lengths of standard pumps
For larger radial displacements resulting from thermal expansion
Assembly/disassembly via four screws
For reduced load on bearings / axial forces on mechanical seals
Type ZS-DKM available with SPLIT hubs
Complying with ATEX (acc. to EU directive 2014/34/EU)
Maintenance-free
Radially dismountable, easy to service
Standard drop-out center lengths available

ROTEX ZS-DKM-H torsionally flexible jaw couplings are elastomer couplings characterized by a compact design.

In spite of low weights and mass moments of inertia of the elastomer couplings they are able to transmit high torques. The compact shaft couplings are characterized by a long service life and sound operating characteristics generated by allover machining.

Thanks to the elastomer (elastomer spider) between the coupling hubs of the jaw couplings shocks respectively torsional vibrations in the drive train are damped. The high temperature-resistant spider material T-PUR® (elastomer) is available in various degrees of hardness. The torsionally flexible ROTEX couplings are used in almost every range of general machinery and plant engineering.
