MULTI MONT SELLA General Technical Description MULTI MONT SELLA W Nominal torques from 63 Nm to 1 000 000 Nm MULTI MONT SELLA Flexible claw coupling The torsionally flexible MULTI MONT SELLA couplings (abbreviation: The coupling is fitted with a separately screwed-on retaining cap MMS) have been built in series since 1958. These pluggable claw that fully encloses the circumferential edge of the rubber elements. couplings, successfully proven over a number of decades, have This screwed connection is not involved in torque transmission. been continually updated to meet technical developments...

Coupling Information MULTI MONT SELLA Standard Types Type MMS-T…W Shaft coupling with taper bush Equipped with a taper bush as a connection element to the shaft. The taper bush is bolted in place in the coupling hub so that a shrink-fit connection free from backlash is established between the coupling hub and the shaft after assembly. The separately bolted on retaining cap allows changing of flexible elements with no need for axial movement of either of the coupling hubs. Type MMS…W Shaft coupling Standard version for connecting two shafts. The separately bolted on retaining cap allows...

Brake disc coupling for brake callipers. For higher requirements, e.g. for control-optimised drives, backlash free versions are available on request. The separately bolted on retaining cap allows changing of flexible elements with no need for axial movement of either of the coupling hubs. Brake disc coupling The TBS type allows radial removal of the brake disc with no need for axial movement of the coupling hubs. The flexible elements can also be easily fitted and removed radially with no need for axial movement of the coupled machines after the retaining cap has been released and...

Coupling Information Material Overview Part No. Part no. can be found in the drawings of the individual types Cast iron coupling hubs are used as standard. If special material specifications exist, other materials are available as an option The technical data applies only to the complete coupling or the corresponding coupling elements. It is the customer/user’s responsibility to ensure that there are no inadmissible loads acting on any of the components. In particular, existing connections, e.g. bolted connections, must be checked with regard to the torques to be transmitted. If necessary,...

General technical data for MULTI MONT SELLA couplings with NBR elements on request. Other rubber materials and other shore hardnesses can also be supplied on request All MULTI MONT SELLA couplings are of balancing grade G 16 for n = 1 500 min-1 according to DIN ISO 21940 as a standard sufficient for normal speed ranges. Should a higher balancing grade be required, please specify the speed and the desired balancing grade when ordering. MULTI MONT SELLA Product Catalogue |

Coupling Information MULTI MONT SELLA Selection of the Coupling Size The coupling size should be selected to ensure that the permissible For drives with combustion engines or prime movers which coupling load is not exceeded in any operating condition are subject to periodically recurring vibratory torques, the final encountered. For drives which are not subject to periodically selection of the coupling should be verified by a full torsional recurring fatigue torques the coupling design may be selected vibration analysis which will be conducted by us on request. based on the driving torque...
