The MULTI CROSS RILLO (short form: MCR) are highly torsionally flexible tyre couplings with progressive torsional deflection characteristic. The salient feature of the MULTI CROSS RILLO shaft couplings is that the coupling hubs are supplied with commercially available taper bushes for nominal torques of up to 14 675 Nm. This allows easy and time saving mounting of the coupling hubs on the shaft. Special tools are not required.
The torque transmission element of the MULTI CROSS RILLO coupling is a rubber tyre reinforced with fabric plies. This tyre transmits the torque without torsional backlash, it is wear-resistant and maintenance-free. The rubber tyre is slotted to allow easy radial mounting without axial displacement of the coupled machines.
MULTI CROSS RILLO shaft couplings reduce torque surges substantially. The high torsional flexibility has a particularly beneficial effect in systems where torsional vibrations occur creating stresses in the drive train.
The use of a rubber tyre as the transmission element compensates to a large extent for axial, radial and angular shaft displacements.
