MULTI MONT ASTRA Flexible Claw Coupling with and without Taper Bushes

D2C – Designed to Customer The guiding principle of Designed to Customer is the recipe for success behind REICH. In addition to the catalogue products, we supply our customers with couplings developed to their specific requirements. The designs are mainly based on modular components to provide effective and efficient customer solutions. The special nature of our close cooperation with our partners ranges from; consulting, development, design, manufacture and integration to existing environments, to customer-specific production, logistics concepts and after-sales service - worldwide.

MULTI MONT ASTRA General Technical Description MULTI MONT ASTRA-W Nominal torques from 10 Nm to 3 600 Nm MULTI MONT ASTRA Flexible Claw Coupling The flexible MULTI MONT ASTRA coupling (short form: MMA) coupling halves. The fixed position of the flexible element allows is a fail-safe claw coupling with flexible element for a torsionally axial deformation so that no detrimental axial loads can act upon flexible shaft connection. The advantage of the comprehensively the machine bearings even if vibratory torques are encountered. machined MULTI MONT ASTRA coupling, and of the claw flanks The...

MULTI MONT ASTRA-T Nominal torques from 10 Nm to 3 600 Nm that even in the event of major shaft tolerances, backlash-free no need for removing connected machinery. MULTI MONT ASTRA and axial fixing on the shaft is ensured. In addition, the slide fit coupling finds its applications in general engineering in all places facilitates axial alignment of the coupling. The flexible element can where a reliable shaft connection is required between the motor be easily changed by axial movement of the coupling halves with MULTI MONT ASTRA Advantages Salient features and advantages of the MULTI MONT...

It is the customer’s/user’s responsibility to ensure 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, further measures, such as additional...

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

MULTI MONT ASTRA Permissible Displacement Values The permissible displacement values as given in the “General Technical Data” table are dependent on the rotational speed and ∆ Kr/a/w = ermissible radial, axial or angular displacement of the p shafts or coupling halves (see “General Technical Data” table). Angular displacement Radial displacement decrease when displacement occurs simultaneously. Coupling Information ∆ Wr/a/w = ermissible radial, axial or angular displacement of the p shaft or coupling halves.
