UNE Flexible Tyre couplings Couplings with Pulley, Brake disc, spacer, SAE Flywheel-shaft, and ATEX normative

The Uneflex coupling is a highly flexible rubber fabric coupling appropriated for compensation of big shifting and shock energies.

Its remarkable high elasticity makes it possible to compensate extremely large offsets in all directions without generating wear. Free from backlash, it is the appropriated coupling to absorb torque peaks and dampen vibrations, due to its quick smoothing qualities.

One of the most interesting features of the Uneflex shaft coupling consists on the simple way in which the elastic tyre is coupled. The tyre, composed of natural rubber with fabric reinforcements, are set on the coupling’s hub and fixed by means of fastening the rings with the screws. The coupling’s rubber tyre is split, allowing the rubber band to be radially replaced without moving the hubs and realigning either the driver or the driven equipment, reducing downtime.

The fabric of the tyre can be aligned radially (R arrangement) or transversally (X arrangement), obtaining a different spring stiffness. R fabric arrangement tyres have a lower torsional stiffness, but the X arrangement is better suited for reverse operations and shock loads.

The Uneflex coupling covers a high range of series: from the standard, to taper lock bushings, with spacer for pump drives, with brake discs and brake drums in accordance with the standards of the cranes of metallurgical plants, with SAE flywheel assembly, with special design tyres to balance greater misalignments for drives with sliding rotor motors and many other designs already created or to be developed for your application.

Features and benefits

Zero maintenance: No routine maintenance or lubrication required
Quick and easy installation and replacement: Design that allows a quick and easy element installation and replacement without moving hubs and realigning either the driver or the driven equipment, reducing downtime
High misalignment capabilities: Compensates extremely large angular, axial and radial misalignments
Vibration dampening and shock absorption: Due to its quick smoothing qualities, provides damping properties to the torsional vibration induced in the system by cyclic variation of the twisting moment and shocks induced by the fast load variation, protecting the entire system
Working temperature range from -20°C to +80°C with the standard tyre of natural compound and from -15°C to +100°C with the chloroprene tyre compound
