MULTI CROSS RILLO General Technical Description MULTI CROSS RILLO Highly Flexible Tyre Coupling with Taper Bushes The MULTI CROSS RILLO (short form: MCR) are highly torsionally MULTI CROSS RILLO shaft couplings reduce torque surges flexible tyre couplings with progressive torsional deflection substantially. The high torsional flexibility has a particularly characteristic. The salient feature of the MULTI CROSS RILLO shaft beneficial effect in systems where torsional vibrations occur couplings is that the coupling hubs are supplied with commercially creating stresses in the drive train....

MULTI CROSS RILLO Nominal torques from 24 Nm to 14 675 Nm MULTI CROSS RILLO Advantages Salient features and advantages of the MULTI CROSS RILLO coupling: ➜ High torsional flexibility with progressive torsional deflection characteristic ➜ High compensating capability for axial, radial and angular displacements ➜ Easy and time saving mounting of the coupling hubs thanks to the use of taper bushes ➜ Radial change of the rubber element without axial movement of the coupled machines ➜ Backlash-free torque transmission even in case of alternating directions of rotation ➜ High torsional vibration...

Coupling Information MULTI CROSS RILLO Assignment to IEC standard motors Shaft couplings for IEC Standard motors acc. to DIN 42637/1 The allocation takes into account usual loads, service factor S = 1.75. For other loads, a design according to “Selection of the proper coupling size” is required. For plants with predominant periodic excitation, the design shall either comply with DIN 740 part 2, or a torsional vibration analysis shall be conducted. The analysis can be provided by us on request. Motor MULTI CROSS RILLO Product Catalogue
